[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1

[0030] Reference Figure 1 and Figure 2 , which is the first embodiment of the present invention, and provides a power grid dynamic switch position positioning system, comprising:

[0031] Processor module, display module, monitoring module, alarm module, signal receiving module, data acquisition module, storage module, detection module and identification module.

[0032] Specifically, Figure 1 The system structure diagram of the present invention is shown, in which the processor module and the display module, the monitoring module, the signal receiving module, the data acquisition module and the detection module are bidirectionally connected; the output end of the monitoring module is connected to the input end of the alarm module; the data acquisition module and the storage module are bidirectionally connected; the detection module and the identification module are bidirectionally connected; the detection module includes a first signal output module and a current and voltage detection device, and the current and voltage detection device is connected to the second signal output module.

[0033] Preferably, the processor module is used to establish a power grid topology model, mark the distribution lines between adjacent substations in the power grid topology model as distribution links, mark each power branch in the distribution link as a topological link, and number the dynamic switches in each line, and each dynamic switch includes a signal receiving unit.

[0034] Furthermore, the signal receiving unit is used to receive signal instructions issued by the first signal output module and the power grid control system.

[0035] Specifically, the first signal output module and the second signal output module use a laser transmitter to convert electrical signals into optical signals and transmit them to the signal receiving unit and the signal receiving module through optical fibers. The signal receiving module and the signal receiving unit use optical receivers to convert optical signals into electrical signals for output through photodiodes.

[0036] Preferably, the present invention utilizes the high bandwidth and anti-interference characteristics of optical fiber to ensure accurate signal transmission in complex electromagnetic environments. Compared with traditional electrical signal transmission that is easily affected by external interference, resulting in signal loss or false alarms, the present invention greatly improves signal reliability through the combination of laser and optical fiber.

[0037] Preferably, the data acquisition module is used to collect current and voltage data of each line and upload it to the processor module. The processor module summarizes and calculates the received circuit voltage data and stores the current and voltage data information in the storage module.

[0038] Specifically, the monitoring module is used to detect the current and voltage data collected by the data acquisition module in real time, and compare the current and voltage data with the standard value. If the collected current and voltage data exceeds the rated range of the standard value, the alarm module will issue an abnormal alarm and display the abnormal information through the display module.

[0039] Preferably, the present invention can accurately reflect the operation status of the power grid by real-time collection of current and voltage data of each power supply cable and substation in the power grid, thereby improving the real-time and accuracy of monitoring. Compared with traditional systems that can only rely on manual inspections, the data acquisition module and the monitoring module can obtain data in real time, reducing the problem of slow maintenance response due to information delays.

[0040] Specifically, the detection module is used to detect whether the dynamic switch is abnormal, the current and voltage detection device is used to detect the current data information passing through the dynamic switch, and the first signal output module is used to control the dynamic switch.

[0041] Furthermore, a switching instruction is sent to the dynamic switch through the first signal output module, the current and voltage detection device detects the current data changes passing through the dynamic switch, and the second signal output module uploads the current data change information to the identification module. The identification module is used to determine whether the current data change information is abnormal, thereby determining whether the dynamic switch is working normally, and the second signal output module sends the status data of the dynamic switch to the signal receiving module.

[0042] Specifically, when the recognition module identifies whether the data is abnormal, the degree of data abnormality can also reflect the severity of the fault, so as to facilitate priority processing. The method for calculating the degree of data abnormality is calculated by the standard deviation method or the Euclidean distance method. The specific formula of the standard deviation method is as follows:

[0043]

[0044] Among them, Z is the calculated value of the abnormality degree, and the larger the absolute value, the higher the abnormality degree; X is the data point; u is the data average; m is the standard deviation of the data.

[0045] When calculating multi-dimensional power grid data, the Euclidean distance method is used to calculate the distance between the data point and the data center. The specific formula for calculating the distance between the data point and the data center is as follows:

[0046]

[0047] Where D is the distance between the data point and the data center. The larger the distance, the higher the degree of abnormality. i is the i-th dimension of the data point; is the average value of the i-th dimension; n is the number of dimensions.

[0048] Preferably, since traditional systems have weak ability to analyze multi-dimensional abnormal data, the present invention introduces a multi-dimensional computing algorithm, and by combining mathematical statistical methods with power grid monitoring, it achieves efficient abnormal point detection, improves the accuracy of fault detection, and can quickly identify anomalies in complex power grid environments.

[0049] Further, such as Figure 2 The figure shows the detection flow chart of the present invention. First, the approximate area of ​​the dynamic switch is located, and then the specific dynamic switch in this area is located, so as to find the abnormal dynamic switch. The positioning of the approximate area includes the following steps: first, the data acquisition module collects abnormal data, the alarm module sends out an alarm, and the abnormal power grid alarm information is received, so that the staff can handle it in advance, which is conducive to reducing the impact of the fault on customers, and extracting the location information of the abnormal point of the power grid from the abnormal power grid alarm information.

[0050] The data acquisition module receives the real-time status information of the power grid transmitted by the power grid information collection system, and can collect the real-time status information of the power grid, including the current information of each power supply cable, the inter-station stage protection start-up signal uploaded by each substation, and the switch status information of the inter-station circuit breaker; the power grid information collection system can collect the current information on the power supply cable measured in real time by the current monitoring device installed on the power supply cable, and can also collect the inter-station stage protection start-up signal and the switch status information of the inter-station circuit breaker uploaded by each substation through the monitoring device installed on the substation and the inter-station circuit breaker.

[0051] According to the real-time status information of the power grid, the target area is located in the pre-stored power grid geographical wiring diagram, and the local wiring diagram of the target area is determined. According to the abnormal changes in the current information of each power supply cable in the real-time status information of the power grid, the abnormal power grid area is determined; according to the area with abnormal data, the target area is located in the power grid geographical wiring diagram; according to the inter-station stage protection start-up signal uploaded by each substation and the switch status information of the inter-station circuit breaker, combined with the power grid geographical wiring diagram, the local wiring diagram in the target area can be determined.

[0052] According to the abnormal alarm information of the power grid and the real-time status information of the power grid, a topological analysis is performed on the local wiring diagram of the target area to determine the approximate location area of ​​the abnormal dynamic switch.

[0053] Furthermore, topological analysis is performed on the local wiring diagram of the target area to determine the approximate location area of ​​the abnormal dynamic switch, including the following steps: determining the type of power grid abnormality based on the location information of the abnormal point of the power grid.

[0054] According to the fault determination algorithm corresponding to the abnormal type of the power grid, the faulty equipment is determined in the local wiring diagram.

[0055] Determine the fault affected area based on the location of the faulty equipment in the local wiring diagram.

[0056] Preferably, the traditional method relies on large-scale blind troubleshooting, while the present invention uses local topology analysis and the topological structure information of the power grid to decompose the problem into a local area, significantly reducing the scope of the investigation, thereby quickly locating and repairing the fault and improving efficiency.

[0057] Specifically, detecting the abnormal position of the dynamic switch includes the following steps: detecting the first dynamic switch in the power grid, identifying whether the dynamic switch fails, and if a failure occurs, repairing or replacing the damaged dynamic switch.

[0058] If the dynamic switch is not faulty, the next numbered dynamic switch is tested and the above steps are repeated.

[0059] After repairing or replacing the damaged dynamic regulating switch, check whether the grid circuit has returned to normal. If the circuit has returned to normal, it means that the dynamic switch in the grid circuit has only this one abnormal point, and the detection is completed.

[0060] If the grid circuit does not return to normal, it means that there are other abnormal points in the dynamic switch in the grid circuit. It is necessary to continue to detect whether the next numbered dynamic switch is abnormal and repeat the above steps.

[0061] Preferably, compared with the traditional system which cannot accurately locate the dynamic switch fault, the present invention realizes one-by-one troubleshooting through step-by-step detection and cooperates with label management, thereby improving the orderliness and efficiency of dynamic switch detection and avoiding omissions.

[0062] In summary, the present invention proposes a power grid dynamic switch position positioning system, which monitors the power grid system in real time through the set processor module, display module, monitoring module, alarm module, signal receiving module, data acquisition module, storage module, detection module and identification module structure. When an abnormality occurs in the dynamic switch in the power grid system, it makes it more convenient to detect and troubleshoot the abnormality of the dynamic switch in the power grid, and can quickly locate the abnormal point, thereby achieving the effect of quickly troubleshooting the abnormality and timely maintenance.

For the purposes of this specification, "computer-readable medium" can be any device that can contain, store, communicate, propagate or transmit a program for use by an instruction execution system, device or apparatus, or in conjunction with such instruction execution systems, devices or apparatuses.

[0069] Embodiment 4 is an embodiment of the present invention, which provides a power grid dynamic switch position positioning system. In order to verify the beneficial effects of the present invention, a scientific demonstration is carried out through simulation experiments.

[0070] This example simulates a power grid dynamic switch position positioning system, including a processor module, a display module, a monitoring module, an alarm module, a signal receiving module, a data acquisition module, a storage module, a detection module and an identification module structure, wherein it is assumed that a dynamic switch labeled 3 fails, at which time the data acquisition module collects abnormal data, and the monitoring module finds that the data is abnormal, thereby performing abnormal detection; firstly, the dynamic switch labeled 1 is detected, and a switch command is issued to the dynamic switch through the first signal output module, and the current and voltage electric measuring device detects the change of its current information and then determines whether it is abnormal through the identification module. The result is that no failure occurs, indicating that the abnormal point is on other dynamic switches, and then the dynamic switch labeled 2 is detected, and the dynamic switch labeled 2 is detected by the same method as above, and no abnormality is detected in the dynamic switch labeled 2, then the dynamic switch labeled 3 is detected, and the dynamic switch labeled 3 is found to be faulty, and it is repaired or replaced in time; then the data acquisition module and the monitoring module detect whether the power grid system is normal, and it is found that the detection data returns to normal, indicating that only the dynamic switch labeled 3 in the power grid system is faulty.

[0071] Secondly, by assuming that the dynamic switches labeled 1 and 3 fail at the same time, based on the abnormal data collected by the data acquisition module, the monitoring module discovers the data anomaly and performs anomaly detection; first, the dynamic switch labeled 1 is detected, and a switch command is issued to the dynamic switch through the first signal output module. The current and voltage measuring device detects the change in its current information and then determines whether it is abnormal through the identification module. It is found that the dynamic switch labeled 1 is faulty and is repaired or replaced in time. Then the data acquisition module and the monitoring module detect whether the power grid system is normal. At this time, if the detection data is still abnormal, it means that other dynamic switches in the power grid system are also faulty. Then the dynamic switch labeled 2 is detected again. The dynamic switch labeled 2 is detected in the same way as above, and no abnormality is detected in the dynamic switch labeled 2. Then the dynamic switch labeled 3 is detected, and it is found that the dynamic switch labeled 3 is faulty, so it is repaired or replaced in time. Then the data acquisition module and the monitoring module detect whether the power grid system is normal. After detection, it is found that the data has returned to normal, indicating that only the dynamic switches labeled 1 and 3 in the power grid system are faulty, indicating that the present invention is performing real-time monitoring on the power grid system. When the dynamic switch in the power grid system is abnormal, the abnormal point can be quickly located, thereby achieving the effect of quickly troubleshooting the abnormality and timely repairing.
