[0022] The following will describe in detail the specific implementation manners of the present disclosure with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0023] With the development of the power system, as a key device in the medium-voltage distribution network, the intelligent, environmentally friendly and integrated requirements of the ring main unit are increasing day by day. Traditional ring main units mostly adopt a design with the separation of primary equipment and secondary equipment, which has problems such as large equipment volume, low intelligence level and inconvenient operation and maintenance.

[0025] Thus, this technical solution integrates Beidou positioning technology and the primary-secondary equipment integration technology in the ring main unit, making the ring main unit have the characteristics of small volume, intelligence, convenient operation and maintenance, and safety and reliability.

[0026] Figure 1 It is a schematic diagram of the external structure of a ring main unit shown according to an exemplary embodiment. As Figure 1 shown, the ring main unit includes a ring main unit body 101, and the ring main unit body 101 can be made of environmentally friendly materials. The ring main unit body 101 can adopt different shapes or external designs in combination with the specific installation environment, which will not be limited herein.

[0027] In some embodiments, the ring main unit body 101 includes a box body, a box door rotatably installed on the front of the box body, and a side door rotatably installed on the side of the box body Figure 2 It is a block diagram of a ring main unit shown according to an exemplary embodiment. As Figure 2 shown, the ring main unit further includes: a primary-secondary integration system 102 arranged on the ring main unit body 101, a Beidou positioning device 103 arranged on the ring main unit body 101, a data acquisition device 104 arranged on the ring main unit body 101, and a main control device 105 arranged on the ring main unit body 101.

[0028] Among them, for the above-mentioned various devices, according to the specific device, they can be arranged inside the main body 101 of the ring main unit or on the ring main unit body at implementable positions, etc.

[0029] For example, the data acquisition device 104 can be arranged on the ring main unit body to monitor the environment where the ring main unit is located and the ring main unit. For example, for reasons of stability, the primary-secondary integration system 102, the Beidou positioning device 103, and the main control device 105 can all be arranged inside the ring main unit body.

[0030] In some embodiments, the primary-secondary integration system 102 includes: a primary switch unit and a secondary control unit. The primary switch unit is an environment-friendly switch unit, and the secondary control unit is used to control the primary switch unit.

[0031] In some embodiments, the primary switch unit can include a load switch and a fuse. Among them, the load switch is used to operate the normal current, and the fuse is used to cut off the short-circuit current. The combination of the two can have the function of a circuit breaker. In some embodiments, the primary switch unit can also adopt the implementation mode of a circuit breaker.

[0032] In some embodiments, the environment-friendly switch unit can have environmental protection characteristics. For example, the circuit breaker of the primary switch unit adopts vacuum arc extinguishing technology; the busbar and the connection terminal adopt epoxy resin casting solid insulation; the insulating medium has no greenhouse gas components and meets the GB / T 11022 withstand voltage standard, etc.

[0033] In some embodiments, the primary switch unit can be connected with a distribution branch to realize the ring main distribution function of the ring main unit.

[0034] In some embodiments, the secondary control unit is further used to obtain the switch state of the primary switch unit and the target parameters of the distribution branch connected to the primary switch unit; according to the switch state and the target parameters, generate a control signal for the primary switch unit, and control the primary switch unit according to the control signal, where the control signal is used to adjust the switch state of the primary switch unit and to switch the distribution branch connected to the primary switch unit.

[0035] In this implementation mode, the secondary control unit can control the primary switch unit according to the switch state and the target parameters.

[0036] In some embodiments, the target parameters can be circuit parameters such as current and voltage.

[0037] In some embodiments, if circuit parameters such as the current and voltage of a distribution branch meet the preset switching conditions, the distribution branch can be switched. Among them, the preset switching conditions can be conditions corresponding to normal switching situations or conditions corresponding to fault situations. Thus, switching can be performed when normal switching is required or when a fault occurs and switching is needed.

[0038] In some embodiments, if the switch state of the primary switch unit is detected to be abnormal, the switch state needs to be adjusted. For example, if the control signal of the primary switch unit is periodic, but the actual switch state does not follow the periodic characteristics of the control signal, it indicates that the switch state is abnormal. For another example, if it is detected that the switch response of the primary switch unit has delays, errors, etc., it indicates that the switch state is abnormal.

[0039] In some embodiments, different abnormal adjustment methods can be adopted according to different abnormal situations. For example, the switch state can be reset and then restored to the previously required controlled switch state, etc.

[0040] In some embodiments, for more implementation manners of the primary-secondary integrated system 102, reference can be made to the technologies of mature primary-secondary equipment in the art. In the embodiments of the present disclosure, the main protection is to integrate the two into a system and set it in the ring main unit.

[0041] In some embodiments, for the Beidou positioning device 103, a mature Beidou positioning module in the art can be adopted to implement the Beidou positioning function.

[0042] In some embodiments, the ring main unit can adopt a modular assembly structure, including: an expandable switch cabinet unit that supports dual-power or multi-power access; an independent compartment design to achieve physical isolation between primary equipment and secondary equipment; and a heat dissipation air duct that combines with a temperature sensor to achieve adaptive temperature control.

[0043] In some embodiments, the ring main unit can adopt a standardized communication interface to be compatible with at least one of the following protocols: IEC 61850-7-420 (new energy grid connection extension protocol); Modbus TCP / RTU; DL / T 860 (power automation communication standard).

[0044] In some embodiments, the main control device 105 is respectively communicatively connected to the primary-secondary integrated system 102, the data acquisition device 104, and the Beidou positioning device 103, and is also communicatively connected to a remote monitoring terminal. The main control device 105 is configured to generate remote monitoring information according to the Beidou positioning information, the ring main unit monitoring data, and the historical switch control information of the secondary control unit, and report the remote monitoring information to the remote monitoring terminal.

[0045] In this embodiment, the master control device 105 can communicate with a primary-secondary integrated system 102, a data acquisition device 104, and a Beidou positioning device 103 respectively to obtain corresponding data, perform risk prediction on the ring main unit according to the corresponding data, and report the risk prediction result and the Beidou positioning as remote monitoring information to the remote monitoring terminal to achieve remote monitoring of the ring main unit.

[0046] Figure 3 is a schematic structural diagram of a ring main unit shown according to an exemplary embodiment, as Figure 3 shown, the ring main unit further includes an environment-friendly heat dissipation device, and the environment-friendly heat dissipation device includes a water storage tank 106, a first heat conduction plate 107, and a second heat conduction plate 108. The water storage tank 106 is fixedly connected inside a bracket at the top of the ring main unit body 101. The first heat conduction plate 107 is fixedly connected to the inner bottom of the water storage tank 106 and has a wavy structure. The second heat conduction plate 108 is fixedly connected to the bottom of the first heat conduction plate 107 and extends into the ring main unit body 101 for transferring the heat inside the ring main unit to the water in the water storage tank 106 for cooling.

[0047] In some embodiments, the first heat conduction plate 107 and the second heat conduction plate 108 can be made of heat-conducting materials.

[0048] In some embodiments, the water volume in the water storage tank 106 can be configured according to the heat dissipation requirement. The higher the heat dissipation requirement, the more water can be configured.

[0049] In some embodiments, the data acquisition device 104 may include an environment sensor and an image sensor.

[0050] Among them, the environment sensor is used to collect the environmental data of the ring main unit, and the image sensor is used to collect the image data of the ring main unit.

[0051] Among them, the environmental data of the ring main unit may be weather, temperature, humidity, etc., and the image data of the ring main unit may include the external image, internal image, and surrounding environment image of the ring main unit, etc.

[0052] In some embodiments, the image data of the ring main unit may be a panoramic image or a non-panoramic image.

[0053] In some embodiments, remote monitoring information can be generated based on Beidou positioning information, ring network cabinet monitoring data, and historical switch control information of the secondary control unit, which may include: determining whether there is a risk in the primary-secondary integrated system 102 according to the historical switch control information; in the case of determining that there is a risk in the primary-secondary integrated system 102, determining ring network cabinet risk prediction information according to the ring network cabinet environmental data and the ring network cabinet image data; in the case of determining that there is no risk in the primary-secondary integrated system 102, determining target data from the ring network cabinet environmental data and the ring network cabinet image data according to the Beidou positioning information, and determining ring network cabinet risk prediction information according to the target data; generating remote monitoring information according to the ring network cabinet risk prediction information and the Beidou positioning information.

[0054] In this implementation, it is first determined whether there is a risk in the primary-secondary integrated system 102. In the case of there being a risk, it indicates that the probability of abnormality of the ring network cabinet is relatively high, and more comprehensive data can be combined for risk prediction. In the case of there being no risk, it indicates that the probability of abnormality of the ring network cabinet is relatively low, and only important data can be combined for risk prediction.

[0055] In some embodiments, the historical switch control information includes: historical switch state adjustment information and historical distribution branch switching information. The historical distribution branch switching information is used to characterize the switching situation of the distribution branch connected to the primary switch unit. The historical switch state adjustment information includes: the number of switch state adjustments, the frequency of switch state adjustments, and the first total duration consumed by the switch state adjustment. The historical distribution branch switching information includes: the number of distribution branch switches, the frequency of distribution branch switches, and the second total duration consumed by the distribution branch switch.

[0056] In this implementation, the secondary control unit can record the number of switch state adjustments, the frequency of switch state adjustments, and the first total duration consumed by the switch state adjustment as the historical switch state adjustment information. And it can record the number of distribution branch switches, the frequency of distribution branch switches, and the second total duration consumed by the distribution branch switch as the historical distribution branch switching information.

[0057] Further, determining whether there is a risk in the primary-secondary integrated system 102 according to the historical switch control information may include: determining a first risk value according to the number of switch state adjustments, the frequency of switch state adjustments, and the first total duration; determining a second risk value according to the number of distribution branch switches, the frequency of distribution branch switches, and the second total duration; determining a target risk value according to the first risk value and the second risk value; and determining whether there is a risk in the primary-secondary integrated system 102 according to the target risk value.

[0058] In some embodiments, the first risk value can be expressed as: Y1 = A1×L1 + B1×F1 + C1×T1, and the second risk value can be expressed as: Y2 = A2×L2 + B2×F2 + C2×T2. Wherein, A1, B1, and C1 respectively represent the risk impact weights of the number of switch state adjustments, the switch state adjustment frequency, and the first total duration, and A2, B2, and C2 respectively represent the risk impact weights of the number of distribution branch switches, the distribution branch switch frequency, and the second total duration. Y1 and Y2 respectively represent the first risk value and the second risk value. L1 and L2 respectively represent the number of switch state adjustments and the number of distribution branch switches. F1 and F2 respectively represent the switch state adjustment frequency and the distribution branch switch frequency. T1 and T2 respectively represent the first total duration and the second total duration.

[0059] Wherein, A1, B1, and C1, as well as A2, B2, and C2 can be determined by means such as offline testing / simulation testing. The greater the impact, the higher the risk impact weight.

[0060] In some embodiments, the first risk value and the second risk value can be averaged to obtain the target risk value.

[0061] In some embodiments, if the target risk value is higher than the preset risk value, it is determined that there is a risk in the primary-secondary fusion system 102. The preset risk value can be configured according to different scenarios, and can be specifically determined by means such as offline testing / simulation testing, and the value is not limited herein.

[0062] In some embodiments, the Beidou positioning information includes Beidou positioning coordinates; according to the Beidou positioning information, determining target data from the ring main unit environmental data and the ring main unit image data may include: obtaining pre-configured reference information, the reference information including: a plurality of preset Beidou positioning coordinate ranges and preset impact factors corresponding to the plurality of preset Beidou positioning coordinate ranges, the preset impact factors including environmental impact factors and / or image impact factors; determining a target Beidou positioning coordinate range that matches the Beidou positioning coordinates from the plurality of preset Beidou positioning coordinate ranges; and determining target data from the ring main unit environmental data and the ring main unit image data according to the preset impact factors corresponding to the target Beidou positioning coordinate range.

[0063] In some embodiments, impact factors corresponding to different Beidou positioning coordinate ranges can be pre-configured as reference information for different Beidou positioning information.

[0064] Exemplarily, in extreme environmental conditions, the importance of the image data is lower than that of the environmental data. Therefore, the preset impact factors corresponding to the Beidou positioning coordinate range corresponding to the extreme environment include: environmental impact factors.

[0065] Exemplarily, in a relatively common environmental situation, the importance of image data is similar to that of environmental data. Therefore, the preset influence factors corresponding to the Beidou positioning coordinate range for the ordinary environment may include environmental influence factors and image influence factors.

[0066] Exemplarily, in an environment with a large number of external objects (such as a large number of people), the importance of image data is higher than that of environmental data. Therefore, the preset influence factors corresponding to the Beidou positioning coordinate range for this environment may include image influence factors.

[0067] In some embodiments, the environmental influence factor and the image influence factor may be represented by different identifiers respectively. For example, the environmental influence factor is 1 and the image influence factor is 2. Then, when configuring the reference information, if the environmental influence factor corresponding to a Beidou positioning range is 1 + 2, it means that both the environmental influence factor and the image influence factor are included; if the environmental influence factor corresponding to a Beidou positioning range is 1, it means that only the environmental influence factor is included.

[0068] Furthermore, from multiple preset Beidou positioning coordinate ranges, the target Beidou positioning coordinate range that matches the Beidou positioning coordinate is determined. It can be understood that the Beidou positioning coordinate is within the preset Beidou positioning coordinate range that matches it.

[0069] In some embodiments, according to the preset influence factors corresponding to the target Beidou positioning coordinate range, determining the target data from the ring network cabinet environmental data and the ring network cabinet image data may include: if the preset influence factors include environmental influence factors and image influence factors, the target data includes the ring network cabinet environmental data and the ring network cabinet image data; if the preset influence factors include environmental influence factors, the target data includes the ring network cabinet environmental data; if the preset influence factors include image influence factors, the target data includes the ring network cabinet image data.

[0070] In some embodiments, the implementation manner of determining the ring network cabinet risk prediction information based on the ring network cabinet environmental data and the ring network cabinet image data may be the same as the implementation manner of determining the ring network cabinet risk prediction information based on the target data, where the specific difference lies in the data involved. Therefore, taking the target data as an example, the method of risk prediction is introduced.

[0071] In some embodiments, determining the risk prediction information of the ring main unit according to the target data may include: determining a risk prediction identifier corresponding to the target data, wherein the ring main unit environmental data and the ring main unit image data correspond to different risk prediction identifiers, and the dimensions of the risk prediction information of the ring main unit corresponding to different risk prediction identifiers are different; preprocessing the target data to obtain the preprocessed target data; and determining the risk prediction information under the dimension corresponding to the risk prediction identifier according to the preprocessed target data and the risk prediction identifier through a pre-trained risk prediction model, wherein the pre-trained risk prediction model is used to output the risk prediction information according to the input preprocessed target data and the risk prediction identifier.

[0072] In some embodiments, the preprocessing method may be: converting the target data into a data vector. For example, for the environmental parameters corresponding to multiple time points, they can be arranged in chronological order and then converted into a time series vector. Also, for the images corresponding to multiple time points, they can be arranged in chronological order and then converted into an image feature vector.

[0073] Among them, the conversion of the time series vector and the image feature vector can refer to the mature technologies in the field.

[0074] In some embodiments, the ring main unit environmental data corresponds to a first risk prediction identifier, and the dimension of the risk prediction information of the ring main unit corresponding to the first risk prediction identifier is the real-time risk level dimension. The dimension of the risk prediction information of the ring main unit corresponding to the ring main unit image data is the ring main unit change information, and the ring main unit change information includes at least one predicted change amount of the ring main unit parameters.

[0075] Furthermore, the preprocessed target data and the risk prediction identifier can be input into the pre-trained risk prediction model to obtain the risk prediction information under the dimension corresponding to the risk prediction identifier output by the risk prediction model.

[0076] In some embodiments, the training process of the pre-trained risk prediction model includes the following steps: obtaining a training data set, where the training data set includes multiple training samples, and the multiple training samples include training samples corresponding to different monitoring data types. Each training sample includes: sample monitoring data, a risk prediction identifier corresponding to the sample monitoring data, and a risk prediction information label corresponding to the sample monitoring data; initially training the risk prediction model to be trained according to the multiple training samples to obtain the initially trained risk prediction model; testing the initially trained risk prediction model according to the target training samples in the multiple training samples to obtain a test result, where the target training samples include sample monitoring data and a risk prediction information label corresponding to the sample monitoring data; and optimizing and training the initially trained risk prediction model according to the test result to obtain the pre-trained risk prediction model.

[0077] In some embodiments, the pre-trained risk prediction model can be a large model with strong processing capabilities. Among them, the risk prediction identifier can be regarded as a reference information for model processing to assist the large model in achieving more intelligent data processing.

[0078] Among them, the ring main unit environment data and the ring main unit image data belong to different monitoring data types, and furthermore, the ring main unit environment data and the ring main unit image data can also respectively involve different data types.

[0079] In some embodiments, the training dataset can be obtained through measured data or simulation data, and the labels or identifiers therein can be manually labeled or intelligently labeled by the model.

[0080] In some embodiments, training samples corresponding to different monitoring data types can be collected to make the training samples diverse. Among them, the numbers of the training samples corresponding to the environmental data type and the image data type respectively can be kept consistent.

[0081] In some embodiments, first, use multiple training samples to conduct initial training on the risk prediction model to be trained, and obtain the initially trained risk prediction model. Since the initially trained risk prediction model already has a certain risk prediction ability, therefore, part of the sample monitoring data can be output to the model for prediction without identifiers to obtain a prediction result, and then compare this prediction result with the risk prediction information label corresponding to the sample monitoring data to determine the model accuracy and obtain a test result.

[0082] Exemplarily, assuming that the required accuracy of the model is above 95% when it has identifiers, then, when the model has no identifiers, if it can reach an accuracy of 80%, it means that the model optimization training is completed. That is, when testing based on the target training samples, its test accuracy can be slightly lower than that of the samples with identifiers.

[0083] Therefore, according to the test result, the initially trained risk prediction model can be optimized to improve the model accuracy.

[0084] Through this implementation method, the training optimization of the model can be realized with fewer training samples, and the difficulty of model training can be reduced.

[0085] In some embodiments, if the target data involves multiple dimensions, the corresponding risk prediction information also involves multiple dimensions. If the target data only involves one dimension, the corresponding risk prediction information also involves one dimension.

[0086] Further, the ring main unit risk prediction information and Beidou positioning information can be directly integrated into remote monitoring information, so that the remote monitoring terminal can simultaneously obtain the location and risk prediction situation.
