Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and in particular to a method and system for detecting electrical parameters of an old transformer in a mobile substation. Background Art

[0002] A transformer is an electrical device that uses the principle of electromagnetic induction to change AC voltage. It is widely used in industry, agriculture, transportation, urban communities and other fields.

[0003] When a transformer is withdrawn from the power system due to aging, upgrading, failure or other reasons, the old transformers withdrawn from the power system can be re-used by carrying out limited low-cost transformation and packaging them into a mobile substation. As a transfer tool for emergency repair and transformation of other substations, the mobile substation avoids the loss of retired materials while improving the power supply reliability of the substation. It also expands the operating range of the mobile substation through cable connection, so that the mobile station has the ability to operate in complex environments. When the mobile substation needs to be used for outdoor connection operations, the electrical parameters of the transformer on the mobile substation need to be tested to determine the operating status of the transformer, and the high-voltage switch and transformer on the mobile substation are directly connected and used outdoors.

[0004] When high-voltage switches and transformers are connected and used outdoors, the surrounding environment may be subject to high temperatures, animal interference, and rainfall, which may cause abnormal effects on the transformer's electrical parameter detection, such as parameter output deviation and transformer damage. This makes it difficult for the vehicle-mounted mobile substation to carry out emergency repairs on other substations in a timely manner. Summary of the invention

[0005] In order to facilitate the emergency repair of the substation by a vehicle-mounted mobile substation, the present invention provides a method and system for detecting electrical parameters of an old transformer of a mobile substation.

[0006] In a first aspect, the present invention provides a method for detecting electrical parameters of an old transformer in a mobile substation, which adopts the following technical solution:

[0007] A method for detecting electrical parameters of an old transformer in a mobile substation, comprising:

[0008] Obtain electrical detection parameters of the transformer;

[0009] When the electrical detection parameters are inconsistent with the preset reference electrical parameters, a preset trigger signal is output;

[0010] When the preset protection device receives the trigger signal, the environmental detection information around the vehicle-mounted mobile substation, the current time of the area where the vehicle-mounted mobile substation is located, and the vertical height between the protection device and the ground are obtained;

[0011] Determine the light angle based on the environmental detection information;

[0012] Determine the sun's altitude angle based on the current time and light angle;

[0013] Determine the shadow center position corresponding to the protective device according to the solar altitude angle and vertical height;

[0014] Calculate the straight-line distance between the center position of the shadow and the preset center position of the transformer and use it as the protection distance;

[0015] Determine the extension length and rotation angle according to the protection distance and the sun altitude angle;

[0016] The vertical height, extension length and rotation angle are combined to form protection control information and output to the protection device to provide sunshade protection for the transformer.

[0017] By adopting the above technical solution, the protection device is controlled to output protection control information combining vertical height, extension length and rotation angle, so that the transformer can reduce direct sunlight, making the transformer less susceptible to temperature influences to produce parameter output deviations, thereby facilitating emergency repairs of the substation by the vehicle-mounted mobile substation.

[0018] Optionally, the method after obtaining the trigger signal includes:

[0019] Acquire surrounding image information of the protective device;

[0020] Determine the biological location based on surrounding image information and preset biological features;

[0021] Determine the moving distance based on the position of the organism and the center position of the transformer;

[0022] When the moving distance is not greater than the preset reference safety distance, the person detection information is determined based on the surrounding image information;

[0023] Determine whether the person detection information is entered into a preset person database;

[0024] If the person detection information is entered into the preset person database, then continue to obtain surrounding image information;

[0025] If the person detection information is not entered into the preset personnel database, the person's position is retrieved according to the person detection information;

[0026] Alarm information is generated based on the position of the person and the biological being and output to the terminal held by the operator to prompt the operator to handle the situation.

[0027] By adopting the above technical solution, the living things around the protective device are understood, and the animals and non-staff whose moving distance is less than the reference safety distance are output with alarm information to drive them away, so that people or animals around the transformer will not touch or damage the transformer during its operation, thereby enabling the transformer to continue to maintain normal operation.

[0028] Optionally, the specific steps before combining the vertical height, the extension length and the rotation angle to form the protection control information are also included:

[0029] According to the trigger information, the transformer specifications on the vehicle-mounted mobile substation and the shooting range of the preset shooting device when shooting the transformer are obtained;

[0030] Match the displayed height from the preset lift database according to the shooting range and transformer specifications;

[0031] Determine the transformer height according to the transformer specifications;

[0032] Calculate the difference between the transformer height and the displayed height and use it as the reference lifting height;

[0033] Get the actual height between the protective device and the transformer;

[0034] Determine whether the actual height is greater than the reference lifting height;

[0035] When the actual height is greater than the reference lifting height, the vertical height, the extension length and the rotation angle are continuously combined to form the protection control information;

[0036] When the actual height is not greater than the reference lifting height, the adjustment length is determined based on the displayed height and the sun altitude angle;

[0037] The rotation angle, the adjustment length and the display height are combined to form new protection control information and output to the protection device.

[0038] By adopting the above technical solution, the transformer is photographed by a photographing device to understand the operating condition of the transformer, and the protective device is controlled to adjust the height, and then new protection control information combining the rotation angle, adjustment length and display height is output to the protective device, so that the transformer can continue to be protected while understanding the operating condition of the transformer.

[0039] Optionally, the specific steps after forming new protection control information and outputting it to the protection device are also included:

[0040] According to the transformer specifications, the reference temperature value is retrieved;

[0041] Retrieving the ambient temperature around the protective device based on the environmental detection information;

[0042] When the ambient temperature is greater than the reference temperature, the difference between the ambient temperature and the reference temperature is calculated and used as the temperature deviation value;

[0043] Match the operating power from the preset wind wall database based on the temperature deviation value;

[0044] Update the operating power according to the displayed height and adjusted length;

[0045] Using the updated operating power as wind wall control information, and outputting the wind wall control information to a wind wall device preset on the protective device and extending together with the protective device to form a wind wall;

[0046] Obtain the internal temperature value in the protective device;

[0047] When the internal temperature value is greater than the reference temperature value, the difference between the internal temperature value and the reference temperature value is calculated and used as the internal temperature deviation value;

[0048] The skylight blowing power is determined according to the internal temperature deviation value, and a blowing device preset in the skylight of the protective device is controlled to blow air based on the skylight blowing power.

[0049] By adopting the above technical solution, when the ambient temperature is greater than the reference temperature value, the wind wall is opened to isolate the transformer from the temperature around the protective device, so that the transformer is not easily affected by the temperature to produce parameter output deviation. When the internal temperature value is greater than the reference temperature value, the blowing device in the skylight is controlled to blow air, so that the air around the transformer can circulate through the blowing of the wind wall device and the blowing device to cool the transformer.

[0050] Optionally, the method further includes controlling a blowing device preset in the skylight of the protective device to blow air:

[0051] Get the internal humidity value of the protective device;

[0052] Determine the baseline humidity value based on the transformer specifications;

[0053] When the internal humidity value is greater than the reference humidity value, the skylight on the protective device is controlled to close and the internal humidity value is updated according to a preset unit time;

[0054] Calculate the difference between the internal humidity values ​​before and after the update and use it as the humidity deviation value;

[0055] Calculate the quotient of humidity deviation value and unit time and use it as the penetration rate;

[0056] Determine the evaporation rate based on the internal temperature value and unit time;

[0057] When the penetration rate is greater than the evaporation rate, the difference between the penetration rate and the evaporation rate is calculated and used as the velocity deviation value;

[0058] The changed power is determined according to the speed deviation value, and the changed power is output to the wind wall device as new wind wall control information for operation.

[0059] By adopting the above technical solution, the humidity around the transformer is kept constant by controlling the blowing power of the wind wall device, so that the transformer is not easily affected by humidity to cause parameter output deviation.

[0060] Optionally, the method further includes calculating the difference between the maximum value of the internal temperature value and the reference temperature value and using it as the internal temperature deviation value:

[0061] Obtain the heat distribution position of the transformer and the operating temperature value corresponding to the heat distribution position, and arrange the operating temperature values ​​in positive order;

[0062] Determine the heat dissipation power according to the maximum operating temperature value corresponding to the positive sequence;

[0063] Determine the heat distribution range and the concentration position corresponding to the heat distribution range according to each heat distribution position;

[0064] Determine whether the heat distribution range is greater than a preset reference heat dissipation range;

[0065] When the heat distribution range is not larger than the reference heat dissipation range, the heat dissipation device preset at the bottom of the transformer is controlled to perform air blowing heat dissipation based on the concentrated position and heat dissipation power;

[0066] When the heat distribution range is larger than the reference heat dissipation range, the correction factor is determined based on the heat distribution range, the reference heat dissipation range and the ambient temperature value;

[0067] Update the heat dissipation power according to the correction factor;

[0068] Based on the centralized location and the updated cooling power, the cooling device is controlled to perform air blowing cooling.

[0069] By adopting the above technical solution, when the transformer generates temperature during operation, the heat dissipation device is controlled by outputting heat dissipation power to blow air to dissipate heat in the heat distribution range corresponding to the bottom of the transformer, thereby cooling the transformer and making the transformer less susceptible to the influence of temperature to produce parameter output deviation.

[0070] Optionally, the method further includes taking the updated operating power as wind wall control information and outputting the wind wall control information to a wind wall device preset on the protective device and extending together with the protective device to form a wind wall:

[0071] Retrieving the external humidity value outside the protective device based on the environmental detection information;

[0072] Determine whether the external humidity value is greater than a preset reference external humidity value;

[0073] If the external humidity value is not greater than the reference external humidity value, the wind wall control information continues to be output to the wind wall device;

[0074] If the external humidity value is greater than the reference external humidity value, the precipitation parameter of the area corresponding to the center position of the transformer is obtained;

[0075] Determine the diffusion pressure value of rainwater diffusion according to precipitation parameters;

[0076] Match the blowing pressure value from the wind wall database based on the operating power;

[0077] Calculate the difference between the diffusion pressure value and the blowing pressure value and use it as the pressure deviation value;

[0078] Match the increased power from the wind wall database based on the pressure deviation value;

[0079] Calculate the sum of the increased power and the operating power and use it as the adjusted power;

[0080] The operating power in the wind wall control information is replaced based on the adjusted power to reform the wind wall control information.

[0081] By adopting the above technical solution, the wind wall device is controlled to block raindrops and isolate the penetration of ambient humidity, so that the transformer is not easily affected by humidity to cause parameter output deviation and transformer damage.

[0082] Optionally, the specific steps before re-forming the wind wall control information are also included:

[0083] Get the rainfall angle outside the guard;

[0084] Update the diffusion pressure value according to the rainfall angle and precipitation parameters;

[0085] The difference between the diffusion pressure values ​​before and after the update is calculated and used as the diffusion pressure deviation value;

[0086] Determine the regulating power according to the diffusion pressure deviation value;

[0087] Determine the marking number and adjustment number corresponding to the wind wall device according to the rainfall angle and the center position of the transformer;

[0088] Calculate the sum of the adjusted power and the regulated power and use it as the regulated operating power;

[0089] Determine the rainfall deviation angle according to the rainfall angle and the preset reference rainfall angle;

[0090] Determine the reduction of operating power based on the rainfall deviation angle;

[0091] Based on adjusting the operating power to form new wind wall control information, the wind wall device operation with the tag number is controlled, and based on reducing the operating power to form new wind wall control information, the wind wall device operation with the adjusted number is controlled.

[0092] By adopting the above technical solution, when raindrops fall with the wind, the wind wall devices with different numbers are controlled to operate, thereby preventing raindrops from falling into the wind wall and reducing the energy consumption of the wind wall device.

[0093] Optionally, the method further includes combining the rotation angle, the adjustment length and the display height to form new protection control information and outputting the new protection control information to the protection device:

[0094] According to the vehicle-mounted mobile substation, a vehicle-mounted mobile substation that cooperates with each other is obtained and defined as a cooperating vehicle-mounted mobile substation, and a vertical height corresponding to the cooperating vehicle-mounted mobile substation is defined as a vertical cooperating height;

[0095] When the vertical matching height is inconsistent with the displayed height, the difference between the vertical matching height and the displayed height is calculated and used as the height deviation value;

[0096] When the height deviation value is positive, the protective device corresponding to the displayed height is controlled to be lifted to the vertical matching height until the displayed height is consistent with the vertical matching height;

[0097] When the height deviation value is not a positive value, the protective device corresponding to the vertical matching height is controlled to be lifted to the displayed height until the vertical matching height is consistent with the displayed height;

[0098] When the protective device is raised, the coordination position between the vehicle-mounted mobile substation and the matching vehicle-mounted mobile substation is obtained;

[0099] When the vertical matching height is consistent with the display height, the clearance distance between the matching vehicle-mounted mobile substation and the vehicle-mounted mobile substation is determined according to the preset circular platform specifications and matching position;

[0100] Obtaining the electric energy parameters of the vehicle-mounted mobile substation, and using the electric energy parameters of the vehicle-mounted mobile substation as the marked electric energy parameters;

[0101] When the marked electric energy parameter is consistent with the electric energy parameter, the wind wall device of the vehicle-mounted mobile substation is controlled to extend at the gap distance;

[0102] When the marked electric energy parameter is inconsistent with the electric energy parameter, the difference between the marked electric energy parameter and the electric energy parameter is calculated and used as the electric energy deviation value;

[0103] When the electric energy deviation value is positive, the wind wall device of the vehicle-mounted mobile substation is controlled to extend at a gap distance;

[0104] When the electric energy deviation value is negative, the wind wall device of the vehicle-mounted mobile substation is controlled to extend at the gap distance.

[0105] By adopting the above technical solution, when the vehicle-mounted mobile substation cooperates with the matching vehicle-mounted mobile substation for operation, the height of the protective device of the vehicle-mounted mobile substation and the matching vehicle-mounted mobile substation is controlled to be flush, and then the wind wall device is controlled to extend to supplement the gap between the protective devices, and the supplementary extended wind wall device is controlled not to start blowing, thereby reducing the energy consumption of the wind wall device when the vehicle-mounted mobile substation cooperates with the matching vehicle-mounted mobile substation.

[0106] In the second aspect, the present application provides an electrical parameter detection system for old transformers in a mobile substation, which adopts the following technical solution:

[0107] An electrical parameter detection system for old transformers in a mobile substation, which applies any electrical parameter detection method for old transformers in a mobile substation, comprises: an acquisition module, which is used to acquire electrical detection parameters, environmental detection information, current time, vertical height, surrounding image information, transformer specifications, shooting range, actual height, internal temperature value, internal humidity value, heat distribution position, operating temperature value, precipitation parameters, rainfall angle, coordinated vehicle-mounted mobile substation, coordinated position and electric energy parameters;

[0111] 1. By controlling the protection device to output the protection control information in combination with the vertical height, extension length and rotation angle, the transformer can reduce direct sunlight, making it less susceptible to temperature influences to produce parameter output deviations, thereby facilitating the vehicle-mounted mobile substation to carry out emergency repairs on the substation;

[0112] 2. When the ambient temperature is higher than the reference temperature, the wind wall is opened to isolate the transformer from the temperature around the protective device, so that the transformer is not easily affected by the temperature to produce parameter output deviation.

[0119] The following is combined with Figures 1 to 5 The present invention is further described in detail with examples.

[0120] A method for detecting electrical parameters of an old transformer of a mobile substation. When a vehicle-mounted mobile substation is used outdoors, it is necessary to protect against outdoor factors. The sun is detected in real time to protect the transformer on the vehicle-mounted mobile substation from direct sunlight. Further adjustments are made according to the presence of surrounding organisms, rain in the surrounding environment, and temperature or humidity around the transformer to reduce the impact of abnormal operation of the transformer on the vehicle-mounted mobile substation, thereby facilitating emergency repair of the substation by the vehicle-mounted mobile substation.

[0121] Reference Figure 1 The present application embodiment discloses a method for detecting electrical parameters of an old transformer in a mobile substation. The method comprises the following steps:

[0122] Step S100: obtaining electrical detection parameters of the transformer.

[0123] The electrical detection parameter refers to the voltage or current parameter corresponding to the operation of the transformer on the vehicle-mounted mobile substation, and the parameter detected by the voltage sensor preset on the transformer is used as the electrical detection parameter. The vehicle-mounted mobile substation includes a transformer and a transport vehicle for transporting the transformer. In this embodiment, different transformer parameter specifications are set with different numbers of transport vehicles for matching connection, and the vehicle-mounted mobile substation is 35kV.

[0124] Step S101: When the electrical detection parameter is consistent with the preset reference electrical parameter, continue to obtain the electrical detection parameter.

[0125] The reference electrical parameters refer to the reference parameters of voltage or current when the transformer is operating normally. The reference electrical parameters are set in advance by those skilled in the art and will not be described in detail here. When the electrical detection parameters are consistent with the reference electrical parameters, it means that the transformer is operating normally, so the electrical detection parameters continue to be obtained.

[0126] Step S102: when the electrical detection parameter is inconsistent with the preset reference electrical parameter, output a preset trigger signal.

[0127] The trigger signal refers to a signal that controls the start-up of the protective device. The trigger signal is set in advance by a person skilled in the art and will not be described in detail here. When the electrical detection parameters are inconsistent with the reference electrical parameters, it means that the transformer is affected by factors in the outdoor environment, resulting in abnormal operation of the transformer, so the trigger information is output to the protective device. The protective device refers to a device that is used to prevent the transformer from being affected by factors in the outdoor environment.

[0128] The protective device can be a protective shell or a protective shed arranged on the transport vehicle. In this embodiment, the protective device includes a circular platform and a lifting rod, the lifting rod is installed on the side of the circular platform close to the transport vehicle and is used to control the lifting and lowering of the circular platform and drive the circular platform to rotate, the circular platform is installed with temperature, humidity, optical sensors and a number of image detection devices, an extension part that can be extended is installed on the circular platform, the area corresponding to the maximum extension of the extension part and the circular platform can be rotated in real time according to the position of the sun to block the sunlight, the extension part is fan-shaped and the arc on the extension part and the straight line parts on both sides corresponding to the arc are installed with wind wall devices, each wind wall device has a separate number, when the extension part is extended, the wind wall devices extending from the straight line parts on both sides corresponding to the arc on the extension part are in operation.

[0129] Step S103: When the preset protection device receives the trigger signal, the environmental detection information around the vehicle-mounted mobile substation, the current time of the area where the vehicle-mounted mobile substation is located, and the vertical height between the protection device and the ground are obtained.

[0130] Environmental detection information refers to the information corresponding to the environment surrounding the protective device. When the protective device receives a trigger signal, it indicates that the protective device starts to operate. Therefore, the parameters such as temperature, humidity and light obtained after detection by various sensors on the protective device are combined to form environmental detection information.

[0131] The current time refers to the current time in the area where the protection device is located. The current time is obtained by querying the time in the area where the protection device is located through the network.

[0132] The vertical height refers to the vertical height between the protective device and the ground. The distance between the protective device and the transport vehicle is detected by an infrared sensor preset in the protective device, and the sum of the distance and the preset reference height of the protective device on the transport vehicle is calculated as the vertical height.

[0133] The reference height refers to the distance between the bottom of the protective device and the ground when the protective device is transported by a transport vehicle. The reference height is pre-set and stored by the operator.

[0134] Step S104: Acquire the light angle according to the environment detection information.

[0135] The light angle refers to the angle of light corresponding to the sun shining on the sunshade device. The light angle is determined by retrieving the angle of the sun's rays to the optical sensor on the protective device from the environmental detection information.

[0136] Step S105: Determine the solar altitude angle according to the current time and the light angle.

[0137] The solar altitude angle refers to the height and angle of the sun in real time. The real-time time is used to estimate the position of the sun, and then combined with the light angle to determine the solar altitude angle.

[0138] Step S106: Determine the center position of the shadow corresponding to the protective device according to the solar altitude angle and the vertical height.

[0139] The center position of the shadow refers to the position of the center of the shadow formed by the protective device. It is analyzed by the vertical height of the protective device and the sun exposure corresponding to the solar altitude angle, and the center position of the shadow corresponding to the center position of the circular platform of the shading device is taken as the center position of the shadow.

[0140] Step S107: Calculate the straight-line distance between the center position of the shadow and the preset center position of the transformer and use it as the protection distance.

[0141] The center position of the transformer refers to the center position of the transformer, which is set and stored by the operator in advance. The protection distance refers to the distance required for the shadow to cover the transformer, and the straight-line distance between the center position of the shadow and the center position of the transformer is calculated as the protection distance.

[0142] Step S108: Determine the extension length and the rotation angle according to the protection distance and the solar altitude angle.

[0143] The extension length refers to the length of the radius corresponding to the extension of the protective device with the center of the circular platform. The rotation angle refers to the angle corresponding to the rotation of the circular platform on the protective device. The digital parameter corresponding to the protection distance is used as the extension length, and the vector angle obtained by calculating the difference between the solar altitude angle and the preset reference altitude angle is used as the rotation angle. The reference altitude angle refers to the angle between the sun and the ground when the sun is perpendicular to the ground. It is formed by the operator's pre-setting and storage.

[0144] Step S109: Combine the vertical height, the extension length and the rotation angle to form protection control information and output it to the protection device to provide sunshade protection for the transformer.

[0145] The sunshade control information refers to the control information corresponding to the vertical height, extension length and rotation angle of the protective device. The values ​​corresponding to the vertical height, extension length and rotation angle are converted into output signals corresponding to the protective device to serve as the sunshade control information. The sunshade control information is output to the protective device to extend the fan-shaped part of the protective device to shade the transformer, thereby reducing the probability of the transformer temperature rising due to direct sunlight on the transformer, resulting in transformer damage or abnormal parameter output, and thus facilitating the vehicle-mounted mobile substation to carry out emergency repairs on the substation.

[0146] The methods after obtaining the trigger signal include:

[0147] Step S200: Acquire surrounding image information of the protection device.

[0148] The surrounding image information refers to the image of the surrounding environment of the protective device, which is obtained by combining the images taken by various cameras on the protective device.

[0149] Step S201: Determine the biological position according to surrounding image information and preset biological features.

[0150] Biological features refer to the morphological features corresponding to animals, which are set and stored in advance by the operator. Biological positions refer to the positions where there are organisms around the protective device, and the positions corresponding to the biological features are identified from the surrounding image information as the biological positions.

[0151] Step S202: Determine the moving distance according to the biological position and the transformer center position.

[0152] The moving distance refers to the distance that a person or animal moves around the center position of the transformer. The straight-line distance between the biological position and the center position of the transformer is calculated as the moving distance.

[0153] Step S203: when the moving distance is not greater than the preset reference safety distance, determining the person detection information according to the surrounding image information.

[0154] The reference safety distance refers to the safety distance corresponding to the operation of the vehicle-mounted mobile substation, which is pre-set and stored by the operator.

[0155] Human detection information refers to the information obtained by detecting people within the reference safety distance. When the moving distance is greater than the reference safety distance, it means that the person or animal is moving outside the reference safety distance, and there is no situation that affects the operation of the vehicle-mounted mobile substation, so the surrounding image information continues to be obtained. When the moving distance is not greater than the reference safety distance, it means that the person or animal is moving within the reference safety distance, and there is a situation that affects the operation of the vehicle-mounted mobile substation, so the face or position information corresponding to the preset human features is identified through the surrounding image information and combined to form human detection information. Human features refer to the facial and body features corresponding to the person. The human features are set in advance by technicians in this field and will not be repeated here.

[0156] Step S204: Determine whether the person detection information is entered into the preset person database. If yes, jump to step S205. If no, jump to step S206.

[0157] Determine whether the person detection information is entered into the preset personnel database, so as to determine whether the person within the reference safety distance will cause impacts such as contact or damage to the operation of the transformer. The personnel database pre-stores the facial recognition information corresponding to each person who operates the transformer. The personnel database is formed by the operator pre-recognizing and acquiring the features of each person and storing them.

[0158] Step S205: Continue to obtain surrounding image information.

[0159] When the person detection information is entered into the personnel database, it means that the personnel within the reference safety distance will not cause any impact on the operation of the transformer, such as touching or damaging it, so the surrounding image information continues to be obtained.

[0160] Step S206: Retrieve the person's position according to the person detection information.

[0161] The person position refers to the position of the person within the reference safety distance. When the person detection information is not entered into the person database, it means that the person within the reference safety distance may cause contact or damage to the operation of the transformer. Therefore, the person position is retrieved from the person detection information.

[0162] Step S207: generating an alarm message according to the position of the person and the position of the organism and outputting the alarm message to the terminal held by the operator to prompt the operator to process the alarm message.

[0163] Alarm information refers to information that emits a warning sound to prompt people or animals within a reference safety distance to leave, and prompts the operator to drive away the people or animals. The alarm information is formed by combining the parameters corresponding to the position of the person and the position of the organism, and the alarm information is output to the terminal held by the operator to prompt the operator to process it, so that it is not easy for people or animals around to touch or damage the transformer during operation, thereby enabling the transformer to continue to maintain normal operation.

[0164] It also includes the specific steps before combining the vertical height, extension length and rotation angle to form the protection control information:

[0165] Step S300: obtaining the transformer specifications on the vehicle-mounted mobile substation and the shooting range of the preset shooting device when shooting the transformer according to the trigger information.

[0166] When the protection device receives the trigger information, the transformer specification refers to the specification of the transformer on the mobile substation, and the operator pre-queries the transformer specification to obtain the transformer specification. The shooting range refers to the range corresponding to the transformer shot by the camera, and the operator pre-enters the shooting parameters of the camera to obtain the shooting range.

[0167] Step S301: Match the display height from a preset lifting database according to the shooting range and transformer specifications.

[0168] The display height refers to the height between the protective device and the transport vehicle when the transformer is displayed within the shooting range. The display height is matched from the preset lifting database through the shooting range. The lifting database stores the display heights corresponding to different shooting ranges and transformer specifications. The lifting database is a database set by humans and will not be described in detail here. In this embodiment, the position of the shooting device is fixed on each transport vehicle, and there are transformers of different specifications on each transport vehicle, so the display heights corresponding to each transformer are different.

[0169] Step S302: Retrieve the transformer height according to the transformer specifications.

[0170] Transformer height refers to the height of the transformer, which is obtained by retrieving the transformer height from the transformer specifications.

[0171] Step S303: Calculate the difference between the transformer height and the display height and use it as the reference lifting height.

[0172] The reference lifting height refers to the reference height to which the protective device needs to be lifted when the transformer is displayed within the shooting range. The difference between the transformer height and the display height is calculated and used as the reference lifting height.

[0173] Step S304: obtaining the actual height between the protective device and the transformer.

[0174] The actual height refers to the actual height between the circular platform of the protective device and the transformer. The distance between the circular platform and the transformer is detected by an infrared sensor preset on the circular platform as the actual height.

[0175] Step S305: Determine whether the actual height is greater than the reference lifting height. If yes, jump to step S306. If no, jump to step S307.

[0176] By determining whether the actual height is greater than the reference lifting height, it is determined whether the protective device needs to be lifted.

[0177] Step S306: Continue to output protection control information.

[0178] When the actual height is greater than the reference lifting height, it indicates that the protection device does not need to be lifted, so the protection control information continues to be output to the protection device.

[0179] Step S307: Determine the adjustment length according to the displayed altitude and the solar altitude angle.

[0180] The adjustment length refers to the length of the radius corresponding to the extension of the protective device with the center of the circular platform. The adjustment length is matched from the preset extension database through the display height and the sun altitude angle. The extension database stores the adjustment lengths corresponding to different display heights and sun altitude angles. The extension database is a manually set database and will not be described in detail here.

[0181] Step S308: Combining the rotation angle, the adjustment length and the display height to form new protection control information and outputting it to the protection device.

[0182] By combining the parameters corresponding to the rotation angle, adjustment length and display height to form new protection control information and output it to the protection device, the transformer can continue to be protected from the sun when the camera is photographing the transformer.

[0183] Reference Figure 2 , and also includes the specific steps after forming new protection control information and outputting it to the protection device:

[0184] Step S400: Retrieve a reference temperature value according to transformer specifications.

[0185] The reference temperature value refers to the maximum temperature value that the transformer can tolerate during operation. The reference temperature value is obtained from the transformer specifications.

[0186] Step S401: obtaining the ambient temperature around the protective device based on the environmental detection information.

[0187] The ambient temperature refers to the temperature of the environment surrounding the protective device, which is obtained by obtaining the ambient temperature from the environmental detection information.

[0188] Step S402: When the ambient temperature is not greater than the reference temperature value, continue to determine the ambient temperature.

[0189] When the ambient temperature is not greater than the reference temperature value, it means that the transformer is not prone to parameter output deviation when operating at the ambient temperature, so continue to determine the ambient temperature.

[0190] Step S403: When the ambient temperature is greater than the reference temperature value, the difference between the ambient temperature and the reference temperature value is calculated and used as the temperature deviation value.

[0191] The temperature deviation value refers to the deviation between the ambient temperature and the reference temperature value. When the ambient temperature is greater than the reference temperature value, it means that the transformer is prone to parameter output deviation when operating at the ambient temperature. Therefore, the difference between the ambient temperature and the reference temperature value is calculated and used as the temperature deviation value.

[0192] Step S404: matching the operating power from a preset wind wall database based on the temperature deviation value.

[0193] The operating power refers to the power of the wind wall device, and the operating power is matched from the preset wind wall database through the temperature deviation value. The wind wall database stores the operating power corresponding to different temperature deviation values. The wind wall database is a manually set database and will not be described here.

[0194] Step S405: Update the operating power according to the displayed height and the adjusted length.

[0195] By calculating the quotient of the displayed height and the preset benchmark blowing height as the height correction coefficient, calculating the quotient of the adjusted length and the preset benchmark extension length as the extension correction coefficient, calculating the product of the height correction coefficient and the extension correction coefficient as the correction coefficient, and then calculating the product of the correction coefficient and the operating power as the new operating power. The benchmark blowing height refers to the benchmark distance between the protective device and the ground when the wind wall device is blowing. The benchmark extension length refers to the benchmark distance corresponding to the extension when the wind wall device needs to change the blowing power. The benchmark blowing height and the benchmark extension length are set in advance by those skilled in the art and will not be elaborated here.

[0196] Step S406: Using the updated operating power as wind wall control information, and outputting the wind wall control information to a wind wall device that is preset on the protective device and extends together with the protective device to form a wind wall.

[0197] Wind wall control information refers to control information that controls the wind wall device to blow air to form a wind wall. By using the updated operating power as the wind wall control information and outputting the wind wall control information to the wind wall device to form a wind wall, it is possible to easily circulate the temperature of the surrounding environment and the temperature around the transformer.

[0198] Step S407: Acquire the internal temperature value of the protection device.

[0199] The internal temperature value refers to the temperature value inside the protective device when the transformer is running. The parameters inside the protective device are detected by a temperature sensor preset on the circular platform as the internal temperature value.

[0200] Step S408: When the internal temperature value is not greater than the reference temperature value, continue to obtain the internal temperature value.

[0201] When the internal temperature value is not greater than the reference temperature value, it means that the transformer is not affected by the temperature when the parameters are output, so the internal temperature value continues to be obtained.

[0202] Step S409: When the internal temperature value is greater than the reference temperature value, a difference between the internal temperature value and the reference temperature value is calculated and used as the internal temperature deviation value.

[0203] The internal temperature deviation value refers to the deviation value between the internal temperature value and the reference temperature value. When the internal temperature value is greater than the reference temperature value, it means that the transformer is affected by temperature when outputting parameters. Therefore, the difference between the internal temperature value and the reference temperature value is calculated and used as the internal temperature deviation value.

[0204] Step S410: determining the skylight blowing power according to the internal temperature deviation value, and controlling the blowing device preset in the skylight of the protective device to blow air based on the skylight blowing power.

[0205] The skylight blowing power refers to the power corresponding to the blowing device in the skylight preset in the circular platform. The skylight blowing power is matched from the preset blowing database through the internal temperature deviation value, and the blowing device is controlled to blow in the direction away from the transformer based on the skylight blowing power, so that the air around the transformer can be circulated through the blowing of the wind wall device and the blowing device to cool the transformer. The blowing device can be a fan controlled by a motor. The skylight blowing power corresponding to different internal temperature deviation values ​​is stored in the blowing database. The blowing database is set by humans and will not be described in detail here.

[0206] Reference Figure 3, and also includes a method for controlling a blowing device preset in a skylight of the protective device to blow air:

[0207] Step S500: Obtain the internal humidity value of the protection device.

[0208] The internal humidity value refers to the humidity value in the protective device, and the parameters in the protective device are detected by a humidity sensor preset on the circular platform as the internal humidity value.

[0209] Step S501: Determine a reference humidity value according to transformer specifications.

[0210] The reference humidity value refers to the maximum humidity value that the transformer can tolerate during operation. The reference humidity value is obtained from the transformer specifications.

[0211] Step S502: When the internal humidity value is greater than the reference humidity value, the skylight on the protection device is controlled to close and the internal humidity value is updated according to a preset unit time.

[0212] When the internal humidity value is not greater than the reference humidity value, it means that the output deviation of the parameters is not likely to occur when the internal humidity value is running around the transformer, so the internal humidity value continues to be obtained. When the internal humidity value is greater than the reference humidity value, it means that the output deviation of the parameters is likely to occur when the internal humidity value is running around the transformer, so the skylight on the control protection device is closed, and the internal humidity value after the preset unit time is obtained as the updated internal humidity value. The unit time refers to the time used to detect the change speed of the internal humidity value, which is set in advance by the operator and stored.

[0213] Step S503: Calculate the difference between the internal humidity values ​​before and after the update and use it as the humidity deviation value.

[0214] The humidity deviation value refers to the deviation value between the internal humidity values ​​before and after the update within a unit time, and the difference between the internal humidity values ​​before and after the update is calculated as the humidity deviation value.

[0215] Step S504: Calculate the quotient of the humidity deviation value and the unit time and use it as the penetration rate.

[0216] The penetration rate refers to the speed at which the humidity around the protective device penetrates into the protective device. The penetration rate is calculated by dividing the humidity deviation value by the unit time.

[0217] Step S505: Determine the evaporation rate according to the internal temperature value and the unit time.

[0218] The evaporation rate refers to the speed at which the temperature generated when the transformer is running can evaporate the moisture in the protective device. The evaporation rate is matched from a preset temperature database through the internal temperature value and unit time. The temperature database stores the evaporation rates corresponding to different internal temperature values ​​and unit time. The temperature database is set manually and will not be elaborated here.

[0219] Step S506: When the penetration rate is greater than the evaporation rate, the difference between the penetration rate and the evaporation rate is calculated and used as the speed deviation value.

[0220] The speed deviation value refers to the deviation between the penetration speed and the evaporation speed. When the penetration speed is not greater than the evaporation speed, it means that the humidity around the transformer will decrease when the parameters are output and it is not easy to have parameter deviation, so continue to obtain the internal humidity value. When the penetration speed is greater than the evaporation speed, it means that the humidity around the transformer will not decrease when the parameters are output and it is easy to have parameter deviation, so the difference between the penetration speed and the evaporation speed is calculated and used as the speed deviation value.

[0221] Step S507: Determine the changed power according to the speed deviation value, and output the changed power as new wind wall control information to the wind wall device.

[0222] The changed power refers to the power of the wind wall device after it is changed. The changed power is matched from the wind wall database through the speed deviation value. The wind wall database also stores the changed power corresponding to different speed deviation values. By outputting the changed power as new wind wall control information to the wind wall device for operation, the power of the wind wall operation can be increased to reduce the humidity around the protective device from penetrating into the transformer, so that the transformer parameter output deviation is not likely to occur.

[0223] Further, the method for calculating the difference between the penetration rate and the evaporation rate and using it as the rate deviation value comprises the following steps:

[0224] Step S510: Determine the extension area according to the adjusted length and the preset extension specification.

[0225] The extension specification refers to the size specification of the extension part, which is set and stored by the operator in advance. The extension area refers to the area extended by the extension part on the circular platform. The size parameter corresponding to the adjustment length is retrieved from the extension specification, and the product of the adjustment length and the size parameter is calculated as the extension area.

[0226] Step S511: Calculate the product of the extended area and the display height and use it as the extended volume.

[0227] The extended volume refers to the volume enclosed by the wind wall corresponding to the extended part of the circular platform. The extended volume is calculated by the product of the extended area and the displayed height.

[0228] Step S512: Determine the display volume according to the display height, the preset circular platform specifications and the extension volume.

[0229] The circular platform specification refers to the size specification corresponding to the circular platform. The displayed volume refers to the volume enclosed by the wind wall corresponding to the displayed height of the protective device. The area of ​​the circular platform is calculated according to the circular platform specifications, and the product of the area of ​​the circular platform and the displayed height is calculated as the unextended volume, and then the sum of the unextended volume and the extended volume is calculated as the displayed volume.

[0230] Step S513: Determine a reference internal volume according to the speed deviation value.

[0231] The reference internal volume refers to the volume that the wind wall of the protective device needs to enclose when the evaporation rate is not greater than the penetration rate. The reference internal volume is matched from the preset evaporation database through the speed deviation value. The evaporation database stores the reference internal volumes corresponding to different speed deviation values. The evaporation database is a manually set database and will not be described in detail here.

[0232] Step S514: Calculate the difference between the reference internal volume and the displayed volume and use it as the volume deviation value.

[0233] The volume deviation value refers to the deviation value between the reference internal volume and the displayed volume, and the difference between the reference internal volume and the displayed volume is calculated as the volume deviation value.

[0234] Step S515: determining an offset angle according to the volume deviation value and the display height, and controlling the operation of the wind wall device based on the offset angle.

[0235] The offset angle refers to the angle after the wind wall device is offset when blowing air. The offset angle is calculated from a preset calculation database through the volume deviation value and the display height, and the wind wall device is controlled to operate at the offset angle. This can reduce the volume formed by the protective device and the wind wall device, so that the humidity around the transformer remains unchanged during operation, making it less likely for transformer parameter output deviations to occur.

[0236] It also includes a method for calculating the difference between the internal temperature value and the reference temperature value and using it as the internal temperature deviation value:

[0237] Step S600: Obtain the heat distribution positions of the transformer and the operating temperature values ​​corresponding to the heat distribution positions, and arrange the operating temperature values ​​in positive order.

[0238] The heat distribution position refers to the distribution position of the heat generated at the bottom of the transformer, and the operating temperature value refers to the temperature value corresponding to the heat distribution position when the transformer is running. The position parameter of the heat detected by the optical fiber temperature sensor preset at the bottom of the transformer is used as the heat distribution position, and the temperature parameter detected by the optical fiber temperature sensor is used as the operating temperature value. The operating temperature values ​​corresponding to each heat distribution position are arranged from small to large.

[0239] Step S601: Determine the heat dissipation power according to the maximum operating temperature value corresponding to the positive sequence.

[0240] The heat dissipation power refers to the power of the heat dissipation device for the transformer. The heat dissipation power is matched by the maximum operating temperature value corresponding to the positive sequence from the preset heat dissipation database. The heat dissipation database stores the heat dissipation power corresponding to different operating temperature values. The heat dissipation database is a database set by humans and will not be described here. The heat dissipation device refers to a fan that is set at the bottom of the transformer and can move horizontally.

[0241] Step S602: determining a heat distribution range and a concentrated position corresponding to the heat distribution range according to each heat distribution position.

[0242] The heat distribution range refers to the range of heat distribution when the transformer is running, and the concentrated position refers to the center position of the heat distribution range. The heat distribution positions are connected by straight lines, and the range corresponding to the straight line connection away from the center position of the transformer after the connection is taken as the heat distribution range, and the center position of the shape corresponding to the heat distribution range is taken as the concentrated position.

[0243] Step S603: Determine whether the heat distribution range is greater than a preset reference heat dissipation range.

[0244] The reference heat dissipation range refers to the maximum range in which the heat dissipation device can dissipate heat when operating at the heat dissipation power. The reference heat dissipation range is set in advance by those skilled in the art and will not be described in detail here. By determining whether the heat distribution range is greater than the reference heat dissipation range, it is determined whether the heat dissipation device can directly dissipate the heat distribution range at the heat dissipation power.

[0245] Step S604: When the heat distribution range is not greater than the reference heat dissipation range, the heat dissipation device preset at the bottom of the transformer is controlled to perform air blowing heat dissipation based on the concentrated position and the heat dissipation power.

[0246] When the heat distribution range is not larger than the reference heat dissipation range, it indicates that the heat dissipation device can directly dissipate heat within the heat distribution range under the heat dissipation power. Therefore, the heat dissipation device is controlled to move to a centralized position and the transformer is cooled by air blowing at the heat dissipation power.

[0247] Step S605: When the heat distribution range is greater than the reference heat dissipation range, a correction coefficient is determined according to the heat distribution range, the reference heat dissipation range and the ambient temperature value.

[0248] The correction coefficient refers to the coefficient used to correct the heat dissipation power. When the heat distribution range is larger than the reference heat dissipation range, it means that the heat dissipation device cannot directly dissipate the heat distribution range under the heat dissipation power. Therefore, the product of the area corresponding to the heat distribution range and the reference heat dissipation range is calculated and used as the correction reference coefficient. Then, the correction coefficient is matched from the preset correction database through the ambient temperature value and the reference coefficient. The correction database is set manually and will not be described in detail here.

[0249] Step S606: Update the heat dissipation power according to the correction coefficient.

[0250] The product of the correction factor and the heat dissipation power is calculated and used as the new heat dissipation power.

[0251] Step S607: Controlling the heat dissipation device to perform air blowing and heat dissipation based on the centralized location and the updated heat dissipation power.

[0252] By controlling the heat dissipation device to move to a centralized position and using the updated heat dissipation power to blow air to dissipate heat to the transformer, the transformer can be cooled, and the temperature is unlikely to cause a parameter output deviation of the transformer.

[0253] Reference Figure 4 , further comprising a method before taking the updated operating power as wind wall control information and outputting the wind wall control information to a wind wall device preset on the protective device and extending together with the protective device to form a wind wall:

[0254] Step S700: Retrieve the external humidity value outside the protective device based on the environmental detection information.

[0255] The external humidity value refers to the humidity value outside the protective device, and is obtained by retrieving the humidity parameter detected by the corresponding humidity sensor from the environmental detection information to serve as the external humidity value.

[0256] Step S701: Determine whether the external humidity value is greater than a preset reference external humidity value. If not, jump to step S702; if yes, jump to step S703.

[0257] The reference external humidity value refers to the minimum humidity value of the environment outside the protective device when it starts to rain. By judging whether the external humidity value is greater than the preset reference external humidity value, it is judged whether it is raining in the environment around the protective device.

[0258] Step S702: Continue to output the wind wall control information to the wind wall device.

[0259] When the external humidity value is not greater than the reference external humidity value, it indicates that there is no rain in the surrounding environment, and the wind wall control information continues to be output to the wind wall device.

[0260] Step S703: Obtain precipitation parameters of the area corresponding to the center position of the transformer.

[0261] Precipitation parameters refer to the volume, weight and speed of rain falling per unit time in the area where the mobile substation is located. When the external humidity value is greater than the reference external humidity value, it means that it is raining in the surrounding environment. The precipitation situation in the corresponding area is queried through the network to determine the precipitation amount, and the piezoelectric rain gauge preset on the protective device is used to calculate the impact force of the falling raindrops and the rain weight and rain speed in combination with the principles of physics. The data corresponding to the precipitation amount, rain weight and rain speed are combined to form precipitation parameters.

[0262] Step S704: determining the diffusion pressure value of rainwater diffusion according to the precipitation parameters.

[0263] The diffusion pressure value refers to the pressure value corresponding to the diffusion flow of rainwater around in unit time. The precipitation volume in unit time is determined by precipitation parameters. The density of water, weight of rainwater and speed of rainwater are integrated to calculate the pressure value of rainwater on the surrounding area as the diffusion pressure value.

[0264] Step S705: Match the blowing pressure value from the wind wall database based on the operating power.

[0265] The blowing pressure value refers to the pressure value caused by the wind wall device when blowing, and the blowing pressure value is retrieved after matching and searching from the wind wall database through the operating power. The wind wall database also stores the blowing pressure values ​​corresponding to different operating powers, which will not be described here.

[0266] Step S706: Calculate the difference between the diffusion pressure value and the blowing pressure value and use it as the pressure deviation value.

[0267] The pressure deviation value refers to the deviation value between the diffusion pressure value and the blowing pressure value. The difference between the diffusion pressure value and the blowing pressure value is calculated and used as the pressure deviation value.

[0268] Step S707: matching the increased power from the wind wall database based on the pressure deviation value.

[0269] The increased power refers to the increased power required by the wind wall device in rainy conditions. The increased power is retrieved and matched from the wind wall database through the pressure deviation value.

[0270] Step S708: Calculate the sum of the increased power and the operating power and use it as the adjusted power.

[0271] Adjusted power refers to the power of the wind wall device after adjustment in rainy conditions. The adjusted power is calculated by adding the sum of the increased power and the operating power.

[0272] Step S709: replacing the operating power in the wind wall control information based on the adjusted power to reform the wind wall control information.

[0273] By replacing the numerical value corresponding to the operating power in the wind wall control information with the adjusted power to reform the wind wall control information and output it to the wind wall device for blowing, it is not easy for the humidity generated by rain to cause data detection deviation on the transformer.

[0274] Reference Figure 5 , also includes the specific steps before re-forming the wind wall control information:

[0275] Step S800: Obtain the rainfall angle outside the protective device.

[0276] The rainfall angle refers to the angle at which rainfall falls on the outside of the protective device, and the parameter obtained by detecting the optical raindrop sensor preset on the circular platform is used as the rainfall angle.

[0277] Step S801: updating the diffusion pressure value according to the rainfall angle and precipitation parameters.

[0278] The correction coefficient of the diffusion pressure value is matched from the preset rainfall database according to the rainfall angle, and then the product of the correction coefficient and the diffusion pressure value is calculated and used as the new diffusion pressure value. The correction coefficients of the diffusion pressure values ​​corresponding to different rainfall angles are stored in the rainfall database. The rainfall database is set manually and will not be described in detail here.

[0279] Step S802: Calculate the difference between the diffusion pressure values ​​before and after the update and use it as the diffusion pressure deviation value.

[0280] The diffusion pressure deviation value refers to the deviation value between the diffusion pressure values ​​before and after the update, and the difference between the diffusion pressure values ​​before and after the update is calculated and used as the diffusion pressure deviation value.

[0281] Step S803: determining the adjustment power according to the diffusion pressure deviation value.

[0282] The regulated power refers to the power that the wind wall device needs to regulate, and the regulated power is matched from the wind wall database through the diffusion pressure deviation value. The wind wall database also stores the power of the wind wall device blowing corresponding to different diffusion pressure deviation values, which will not be described in detail here.

[0283] Step S804: Determine the mark number and adjustment number corresponding to the wind wall device according to the rainfall angle and the center position of the transformer.

[0284] The marking number refers to the number corresponding to the wind wall device facing the rainfall angle, and the adjustment number refers to the number that needs to be adjusted for the wind wall device not facing the rainfall angle. The number corresponding to the wind wall device between the center position of the transformer and the rainfall angle is selected from each wind wall device as the marking number, and the numbers corresponding to the remaining wind wall devices are used as the adjustment numbers.

[0285] Step S805: Calculate the sum of the adjusted power and the regulated power and use it as the regulated operating power.

[0286] The regulated operating power refers to the power of the wind wall device after regulation. The sum of the adjusted power and the regulated power is calculated and used as the regulated operating power.

[0287] Step S806: determining a rainfall deviation angle according to the rainfall angle and a preset reference rainfall angle.

[0288] The reference rainfall angle refers to the minimum rainfall angle corresponding to the wind wall device with the adjustment number that needs to be adjusted, which is set and stored in advance by the operator. The rainfall deviation angle refers to the deviation between the rainfall angle and the reference rainfall angle, and the difference between the rainfall angle and the reference rainfall angle is calculated and used as the rainfall deviation angle.

[0289] Step S807: Determine to reduce the operating power according to the rainfall deviation angle.

[0290] Reducing the operating power refers to the power of the wind wall device after the reduction, and the reduced operating power is matched from the wind wall database through the rainfall deviation angle. The wind wall database also stores the reduced operating power corresponding to different rainfall deviation angles, which will not be described in detail here.

[0291] Step S808: Based on adjusting the operating power to form new wind wall control information, control the operation of the wind wall device with the tag number, and based on reducing the operating power to form new wind wall control information, control the operation of the wind wall device with the adjustment number.

[0292] By adjusting the operating power to form new wind wall control information to control the operation of the wind wall device with the mark number, and reducing the operating power to form new wind wall control information to control the operation of the wind wall device with the adjustment number, the wind wall device can be controlled to continue to resist raindrops when the raindrops fall and deviate, and the power of other wind wall devices can be reduced, thereby reducing the energy consumption of the wind wall device.

[0293] It also includes the specific steps of combining the vertical height, the extension length and the rotation angle to form the protection control information and outputting it to the protection device to provide sunshade protection for the transformer:

[0294] Step S900: obtaining mutually cooperating vehicle-mounted mobile substations according to the vehicle-mounted mobile substations and defining them as cooperating vehicle-mounted mobile substations, and defining the vertical height corresponding to the cooperating vehicle-mounted mobile substations as the vertical cooperating height.

[0295] The matching vehicle-mounted mobile substation refers to the vehicle-mounted mobile substation that works in conjunction with the vehicle-mounted mobile substation. The vehicle-mounted mobile substation is used as the reference and the corresponding vehicle-mounted mobile substation when the matching connection is made with the vehicle-mounted mobile substation is used as the matching vehicle-mounted mobile substation. The vertical matching height refers to the height between the protective device on the matching vehicle-mounted mobile substation and the ground.

[0296] Step S901: When the vertical matching height is inconsistent with the display height, the difference between the vertical matching height and the display height is calculated and used as the height deviation value.

[0297] The height deviation value refers to the deviation value between the vertical fit height and the displayed height. When the vertical fit height is inconsistent with the displayed height, it means that there is a cross collision in the protective device. Therefore, the difference between the vertical fit height and the displayed height is calculated and used as the height deviation value.

[0298] Step S903: When the height deviation value is a positive value, the protective device corresponding to the display height is controlled to be lifted to the vertical matching height until the display height is consistent with the vertical matching height.

[0299] When the height deviation value is a positive value, it means that the protective device of the vertical matching height cannot be lowered, so the protective device corresponding to the displayed height is controlled to be raised to the vertical matching height until the displayed height is consistent with the vertical matching height.

[0300] Step S904: When the height deviation value is not a positive value, the protective device corresponding to the vertical matching height is controlled to be lifted to the display height until the vertical matching height is consistent with the display height.

[0301] When the height deviation value is a negative value, it means that the vertical height protection device cannot be lowered, so the protection device corresponding to the vertical matching height is controlled to be raised to the displayed height until the vertical matching height is consistent with the displayed height.

[0302] Step S905: When the protection device is raised, the coordination position between the vehicle-mounted mobile substation and the coordinated vehicle-mounted mobile substation is obtained.

[0303] The matching position refers to the position where the vehicle-mounted mobile substation and the matching vehicle-mounted mobile substation are matched. When the protective device is raised, the circular platform of the protective device is extended, so the operator inputs the position of the transformer corresponding to the transformer specification to obtain the matching position.

[0304] Step S906: When the vertical matching height is consistent with the display height, the gap distance between the matching vehicle-mounted mobile substation and the vehicle-mounted mobile substation is determined according to the preset circular platform specifications and matching position.

[0305] The gap distance refers to the distance between the protective device of the vehicle-mounted mobile substation and the matching vehicle-mounted mobile substation. When the vertical matching height is consistent with the displayed height, it means that the vehicle-mounted mobile substation is flush with the protective device of the matching vehicle-mounted mobile substation. Therefore, the distance between the centers of the two circular platform specifications corresponding to the specifications is calculated, and the difference between the distance and the diameter corresponding to the circular platform specifications is calculated and used as the gap distance.

[0306] Step S907: Acquire the electric energy parameters of the vehicle-mounted mobile substation, and use the electric energy parameters of the vehicle-mounted mobile substation as the marked electric energy parameters.

[0307] The electric energy parameters refer to the parameters of the power supply electric energy corresponding to the vehicle-mounted mobile substation, and the marked electric energy parameters refer to the parameters of the power supply electric energy corresponding to the vehicle-mounted mobile substation. The parameters detected by the electric energy meter preset on the power supply of the vehicle-mounted mobile substation are used as the electric energy parameters, and the parameters detected by the electric energy meter preset on the power supply that cooperates with the vehicle-mounted mobile substation are used as the electric energy parameters.

[0308] Step S908: When the marked electric energy parameter is consistent with the electric energy parameter, control the wind wall device of the vehicle-mounted mobile substation to extend at the gap distance.

[0309] When the marked electric energy parameter is consistent with the electric energy parameter, it means that the wind wall device needs to consume electric energy to supplement the gap. Therefore, the wind wall device that cooperates with the vehicle-mounted mobile substation is controlled to extend by the gap distance, so as to consume the power supply of the vehicle-mounted mobile substation and facilitate the supplement of the power supply of the vehicle-mounted mobile substation.

[0310] Step S909: When the marked power parameter is inconsistent with the power parameter, a difference between the marked power parameter and the power parameter is calculated and used as a power deviation value.

[0311] The electric energy deviation value refers to the deviation value between the marked electric energy parameter and the electric energy parameter. When the marked electric energy parameter is inconsistent with the electric energy parameter, it means that the wind wall device of the vehicle-mounted mobile substation with high electric energy needs to be controlled to extend. Therefore, the difference between the marked electric energy parameter and the electric energy parameter is calculated and used as the electric energy deviation value.

[0312] Step S910: When the power deviation value is a positive value, control the wind wall device of the vehicle-mounted mobile substation to extend at a gap distance.

[0313] When the electric energy deviation value is positive, it means that the electric energy of the vehicle-mounted mobile substation is higher than the electric energy of the vehicle-mounted mobile substation. Therefore, the wind wall device of the vehicle-mounted mobile substation is controlled to extend at a gap distance, and the extended wind wall device is controlled not to start blowing.

[0314] Step S911: When the electric energy deviation value is a negative value, the wind wall device of the vehicle-mounted mobile substation is controlled to extend by the gap distance.

[0315] When the electric energy deviation value is negative, it means that the electric energy of the vehicle-mounted mobile substation is higher than the electric energy of the matching vehicle-mounted mobile substation. Therefore, the wind wall device of the vehicle-mounted mobile substation is controlled to extend at a gap distance, and the extended wind wall device is controlled not to start blowing.
