It is located at the end of the power grid and is a point on a radial network, connected to the substation above and to various electrical equipment below. It generally has a small capacity and a voltage level below 35 kV. It is divided into two categories. Most of them are used for dispatching, dispatching various lines, and balancing the load of each line; there are also some independent ones that play a role in changing the transmission method. With the rapid development of electricity, distribution stations are also playing an increasingly important role.

[0066] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0067] Example 1, please refer to Figure 1-Figure 2 As shown, the technical solution provided by the present invention is: a visual management method for distribution stations based on industrial Internet of Things, and the visual management method for distribution stations is specifically as follows:

[0068] Step S10, constructing a virtual three-dimensional diagram of the power distribution station according to the three-dimensional drawing;

[0069] In practice, the virtual three-dimensional diagram can be used to collect the structural information of the distribution station and the object specification information of the internal objects, and then input the structural information and object specification information into the three-dimensional modeling software to establish a three-dimensional model of the distribution station. At the same time, it can also be obtained through digital twin technology, using physical models, IoT nodes and other data to build a digital twin model of the distribution station, and realize the three-dimensional visualization of the distribution station through augmented reality technology;

[0070] Step S20, obtaining equipment supervision values ​​of electrical equipment in the distribution station according to equipment data analysis and obtaining equipment importance values ​​of electrical equipment in the distribution station according to power data analysis;

[0071] It should be specifically noted that the equipment data and power data may be specifically stored in relevant memories or storage devices. The above-mentioned electrical equipment includes but is not limited to high-voltage switchgear, transformers, etc., wherein the operation data is the commissioning time, the number of operation abnormalities and the number of damage caused by external objects of the electrical equipment in the distribution station, and the number of environmental abnormalities at the location of the distribution station. Operation abnormality refers to the abnormal operation state of the electrical equipment itself, such as high temperature inside the electrical equipment, etc., and damage caused by external objects refers to damage to the electrical equipment caused by external objects, such as insects and rodents entering the interior of the electrical equipment and causing damage to the line. Environmental abnormality refers to abnormalities in the environment at the location of the electrical equipment, such as high temperature environment, water immersion, etc. In this embodiment, only the above-mentioned data are shown for subsequent visual marking; the power data is the number of electrical equipment connected to the electrical equipment in the distribution station, the number of electricity users, and the power radiation area;

[0072] In this embodiment, the calculation process of the device supervision value and the device importance value is as follows:

[0073] Step S201, marking the electrical equipment in the power distribution station as i, where i is the number of the electrical equipment;

[0074] Step S202, obtaining the time when the electrical equipment in the power distribution station is put into use, and subtracting the time when the electrical equipment in the power distribution station is put into use from the current time to obtain the time Ti of the electrical equipment in the power distribution station being put into use;

[0075] Step S203, then obtain the number of abnormal operation times YCi and the number of damages caused by foreign objects WCi of the electrical equipment in the distribution station, as well as the number of environmental abnormalities HCi where the distribution station is located;

[0076] Step S204, substitute the above parameters into the formula, and calculate the equipment supervision value SJi of the electrical equipment in the distribution station through the formula. The specific formula is as follows:

[0077] SJi=Ti×a1+(YCi+WCi+HCi)×a2; where a1 and a2 are weight coefficients, and a1<a2. In practice, a1 can be 0.3 and a2 can be 0.7. The equipment supervision value is used to reflect the degree of management and supervision of electrical equipment. That is, the larger the equipment supervision value, the more the electrical equipment needs to be managed or monitored.

[0078] Step S205, obtaining the number of electric devices YSi, the number of electric users YHi and the electric radiation area connected to the electric equipment in the distribution station, and superimposing the areas of the electric radiation areas to obtain the electric radiation area YMi of the electric equipment in the distribution station;

[0079] In practice, for example, if an electrical device supplies power to two communities, the area of ​​the two communities can be added together to obtain the power radiation area of ​​the electrical device;

[0080] Step S206, using the formula SZi=YSi×b1+YHi×b2+YMi×b3 to calculate the equipment importance value SZi of the electrical equipment in the distribution station; wherein b1, b2 and b3 are all weight coefficients, b1<b2<b3.

[0084] Step S302, the visible value KSi of the electrical equipment in the distribution station is calculated by a formula, and the specific formula is as follows:

[0085] KSi=SJi×c1+SZi×c2; where c1 and c2 are weight coefficients, and c1=c2;

[0086] Step S303, calibrating the control level of the corresponding electrical equipment according to the visible value of the equipment, specifically:

[0087] When the device visibility value is less than the first threshold, the control level of the electrical equipment is the third control level;

[0088] When the device visibility value is greater than or equal to the first threshold and less than the second threshold, the control level of the electrical equipment is the second control level;

[0089] When the device visibility value is greater than or equal to the second threshold, the control level of the electrical equipment is the first control level; wherein the first threshold is less than the second threshold, the control intensity of the first control level is higher than the control intensity of the second control level, and the control intensity of the second control level is higher than the control intensity of the third control level;

[0090] Step S304: Visually mark the electrical equipment according to the control level. The visual mark is specifically:

[0091] If the control level of the electrical equipment is the first control level, the electrical equipment in the virtual three-dimensional diagram will be marked in red;

[0092] If the control level of the electrical equipment is the second control level, the electrical equipment in the virtual three-dimensional diagram will be marked in orange;

[0094] Step S40, determining the inspection route of the electrical equipment in the distribution station according to the control level, and collecting real-time status data of the electrical equipment in the distribution station based on the inspection route;

[0095] In this embodiment, the real-time status data is the real-time temperature value and real-time humidity value of the electrical equipment in the power distribution room at different time points. In addition, relevant data such as real-time voltage value, real-time current value, and real-time dust value can also be collected and used for status analysis of the electrical equipment. In specific implementation, the real-time status data can be collected through various sensors configured on the electrical equipment, and the real-time status data can be sent to the analysis platform for analysis through the gateway;

[0096] In a specific embodiment, the process of determining the inspection route is as follows:

[0097] Step S401, obtaining the device visible value of the electrical equipment corresponding to the first control level, traversing and comparing the device visible values ​​to obtain the maximum value among the device visible values, and taking the electrical equipment corresponding to the maximum value as the first inspection object of the inspection route;

[0098] Step S402, obtaining the adjacent electrical devices of the electrical device that is the first inspection object, and comparing the control levels of the adjacent electrical devices;

[0099] Step S403: If there are no adjacent electrical devices with the same control level, electrical devices are selected as the next inspection object according to the control level from high to low;

[0100] If there are adjacent electrical equipment with the same control level, the control level is used as the first selection factor, and then the equipment visibility value is used as the second selection factor. The electrical equipment is selected as the next inspection object from the largest to the smallest according to the equipment visibility value;

[0101] Step S404, sequentially determine the inspection order of the electrical equipment in the distribution station, and add the inspection times to the virtual three-dimensional map, and sequentially connect them according to the inspection order to obtain the inspection route of the electrical equipment in the virtual three-dimensional map;

[0102] It should be specifically explained that the inspection route in this embodiment is not an actual inspection route, but a collection route for real-time status data corresponding to each electrical equipment in the power distribution station.

[0103] Step S50, judging the equipment operation status of the electrical equipment in the power distribution station based on the real-time status data, and visually displaying the equipment operation status through a virtual three-dimensional diagram;

[0107] Specifically, this embodiment only analyzes the temperature and humidity exceeding the standard of the electrical equipment in the distribution station. In practice, the low temperature of the electrical equipment in the distribution station can also be analyzed;

[0108] Step S503: If the real-time temperature values ​​corresponding to all time points belong to the temperature interval value, and the real-time humidity values ​​corresponding to all time points belong to the humidity interval value, proceed to the next step;

[0109] Step S504, calculate the real-time temperature change rate WS between adjacent time points by formula t and real-time humidity change rate SS t , the formula is as follows:

[0110] WS t =|WD t+1 -WD t | / (T t+1 -T t ); In the formula, T t+1 is the next time point, T t is the current time point, WD t is the real-time temperature value corresponding to the current time point, WD t+1 is the real-time temperature value corresponding to the next time point;

[0111] SS t =|SD t+1 -SD t | / (T t+1 -T t ); in the formula, SD t is the real-time humidity value corresponding to the current time point, SD t+1 The real-time humidity value corresponding to the next time point;

[0112] Step S505, if the real-time temperature change rate between any adjacent time points does not belong to the preset temperature change rate interval or the real-time humidity change rate between any adjacent time points does not belong to the preset humidity change rate interval, then an operation abnormality signal is generated;

[0113] Step S506, if the real-time temperature change rate between all adjacent time points belongs to the preset temperature change rate interval or the real-time humidity change rate between all adjacent time points belongs to the preset humidity change rate interval, then a normal operation signal is generated;

[0114] Step S507: If the corresponding electrical device generates an abnormal operation signal, the red mark corresponding to the electrical device in the virtual three-dimensional map flashes;

[0115] If the corresponding electrical equipment generates a normal operation signal, no operation is performed.

[0116] In this application, if corresponding calculation formulas appear, the above calculation formulas are all dimensionless and take their numerical calculations. The weight coefficients, proportional coefficients and other coefficients in the formulas are set to a result value obtained by quantifying each parameter. The size of the weight coefficient and the proportional coefficient can be determined as long as it does not affect the proportional relationship between the parameter and the result value.
