[0047] FIG2 is a schematic structural diagram of another thunderstorm area power transmission safety monitoring system provided in an embodiment of the present application. DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0049] In the existing technology, it is impossible to analyze the thunderstorm weather characteristics of the transmission area during power transmission, and thus it is impossible to schedule power transmission according to regional characteristics, which affects the stability and safety of power transmission. Based on this, this application proposes the following technical solutions, see below for details:

[0050] In one embodiment, as shown in Figure 1, Figure 1 is a structural schematic diagram of a thunderstorm area power transmission safety monitoring system provided in an embodiment of the present application; the present application provides a thunderstorm area power transmission safety monitoring system, the system includes a transmission platform, a regional feature analysis unit and a transmission impact analysis unit.

[0051] The transmission platform is used to receive a power transmission request sent by the current power supply end, and after determining the power demand end and the transmission area where the power demand end is located according to the power transmission request, send a regional feature analysis signal of the transmission area to the regional feature analysis unit.

[0052] The regional characteristic analysis unit is used to receive the regional characteristic analysis signal, perform thunderstorm characteristic analysis on the transport area according to the regional characteristic analysis signal, and send the thunderstorm characteristic analysis result to the transport impact analysis unit and the transport platform.

[0053] The transmission platform is also used to receive the thunderstorm characteristic analysis results, and formulate the power transmission strategy of the transmission area based on the thunderstorm characteristic analysis results, and send a transmission impact analysis signal to the transmission impact analysis unit in the process of transmitting the power from the current power supply end to the power demand end according to the power transmission strategy.

[0054] The transmission impact analysis unit is used to receive the transmission impact analysis signal and the thunderstorm characteristic analysis result, and perform thunderstorm impact analysis on the real-time power transmission of the transmission platform based on the transmission impact analysis signal and the thunderstorm characteristic analysis result, and send the thunderstorm impact analysis result to the transmission platform so that the transmission platform can determine whether to adjust the power transmission strategy.

[0055] In this embodiment, when the transmission platform transmits the power transmitted by the power supply end, it can receive the power transmission request sent by the current power supply end, and determine the power demand end and the transmission area where the power demand end is located based on the power transmission request. It is understandable that the transmission platform can be connected to multiple power supply ends and power demand ends. In this way, when a power supply end sends a power transmission request to the transmission platform, the transmission platform can determine the power demand end that is currently in urgent need of power transmission and the area where the power demand end is located based on the power transmission request, so that the power demand end and the transmission area corresponding to the power demand end can be obtained. Of course, in this application, a power supply end can supply power to multiple power demand ends at the same time, or it can supply power to one power demand end. When a power supply end supplies power to multiple power demand ends at the same time, the transmission area corresponding to each power demand end can be determined. When a power supply end supplies power to one power demand end, it only needs to determine the transmission area corresponding to the power demand end.

[0056] After the transmission platform determines the power demand end and the corresponding transmission area, it can send a regional characteristic analysis signal related to the transmission area to the regional characteristic analysis unit. After the regional characteristic analysis unit receives the regional characteristic analysis signal, it can perform a thunderstorm characteristic analysis on the transmission area based on the regional characteristic analysis signal, and send the thunderstorm characteristic analysis results to the transmission impact analysis unit and the transmission unit. In this way, after the transmission unit receives the thunderstorm characteristic analysis results, it can formulate a power transmission strategy for the transmission area based on the thunderstorm characteristic analysis results, and transmit the power from the current power supply end to the power demand end according to the power transmission strategy. In this process, the transmission platform can also send a transmission impact analysis signal to the transmission impact analysis unit. After the transmission impact analysis unit receives the transmission impact analysis signal, it can perform a thunderstorm impact analysis on the real-time power transmission process of the transmission platform affected by thunderstorms based on the transmission impact analysis signal and the thunderstorm characteristic analysis results, and send the thunderstorm impact analysis results to the transmission platform so that the transmission platform can determine whether to adjust the power transmission strategy.

[0057] For example, when the transmission impact analysis unit performs a thunderstorm impact analysis on the impact of thunderstorms on the real-time power transmission process of the transmission platform based on the thunderstorm characteristic analysis results, if the analysis results show that the current transmission line will not be affected by the thunderstorm, there is no need to adjust the power transmission strategy. If the analysis results show that the current transmission line will be affected by the thunderstorm, the power transmission strategy can be adjusted, such as adjusting the transmission volume during the period affected by the thunderstorm, or adjusting the transmission time, etc., without any restrictions here.

[0058] In the above embodiment, the system includes a transmission platform, a regional characteristic analysis unit, and a transmission impact analysis unit; the transmission platform can receive a power transmission request sent by the current power supply end, and after determining the power demand end and the transmission area where the power demand end is located based on the power transmission request, send a regional characteristic analysis signal of the transmission area to the regional characteristic analysis unit. After receiving the regional characteristic analysis signal, the regional characteristic analysis unit can perform a thunderstorm characteristic analysis on the transmission area based on the regional characteristic analysis signal, and send the thunderstorm characteristic analysis result to the transmission impact analysis unit and the transmission platform. After receiving the thunderstorm characteristic analysis result, the transmission platform can formulate a power transmission strategy for the transmission area based on the thunderstorm characteristic analysis result, and in the process of transmitting power from the current power supply end to the power demand end according to the power transmission strategy, send a transmission impact analysis signal to the transmission impact analysis unit. After receiving the transmission impact analysis signal and the thunderstorm characteristic analysis result, the transmission impact analysis unit can perform a thunderstorm impact analysis on the impact of thunderstorms on the real-time power transmission process of the transmission platform based on the transmission impact analysis signal and the thunderstorm characteristic analysis result, and send the thunderstorm impact analysis result to the transmission platform for the transmission platform to determine whether to adjust the power transmission strategy. This process analyzes the thunderstorm characteristics of the transmission area corresponding to the transmission platform to prevent the characteristics of the thunderstorm area from affecting power transmission. Power transmission is controlled through thunderstorm characteristic analysis to minimize the impact of thunderstorm characteristics on power transmission. Thunderstorm impact analysis is performed on the real-time power transmission process within the transmission platform. The impact of thunderstorms is monitored and analyzed in real time during the transmission process, which improves monitoring efficiency and avoids the impact of thunderstorms during the transmission process, resulting in abnormal power transmission and the inability to timely detect the aggravation of thunderstorm effects caused by the affected power transmission.

[0059] In one embodiment, the process of the regional characteristic analysis unit performing thunderstorm characteristic analysis on the transport area according to the regional characteristic analysis signal and obtaining the thunderstorm characteristic analysis result may include:

[0060] The regional characteristic analysis unit determines the area where thunderstorms exist within the transmission area based on the regional characteristic analysis signal, and marks the area where thunderstorms exist as a thunderstorm analysis area, and obtains the instantaneous increase in the ground flash frequency corresponding to the thunderstorm in the thunderstorm analysis area, the average probability of the lightning current amplitude in each area in the thunderstorm analysis area, and the average duration period of thunderstorm weather in the thunderstorm analysis area.

[0061] The regional characteristic analysis unit generates a thunderstorm characteristic analysis coefficient in the thunderstorm analysis area based on the instantaneous growth amount, the average probability of the lightning current amplitude in each area, and the average duration period of thunderstorm weather in the thunderstorm analysis area, and determines the thunderstorm characteristic analysis result of the thunderstorm analysis area based on the thunderstorm characteristic analysis coefficient.

[0062] In this embodiment, when the regional characteristic analysis unit performs thunderstorm characteristic analysis on the transmission area based on the regional characteristic analysis signal, it can first determine the area where thunderstorms exist in the transmission area based on the regional characteristic analysis signal, and mark it as a thunderstorm analysis area. Then, the meteorological data of the meteorological station can be used to obtain the instantaneous increase in the ground flash frequency corresponding to the thunderstorm in the thunderstorm analysis area, the average probability of the lightning current amplitude in each area in the thunderstorm analysis area, and the average duration period of thunderstorm weather in the thunderstorm analysis area. In this way, the thunderstorm characteristic analysis coefficient in the thunderstorm analysis area can be generated based on the relevant data obtained, and the thunderstorm characteristic analysis result of the thunderstorm analysis area can be determined based on the thunderstorm characteristic analysis coefficient.

[0063] It can be understood that when the present application determines the area where thunderstorms exist within the transportation area, there may be one or more such areas. Therefore, there may be one or more thunderstorm analysis areas in the present application. When there are multiple thunderstorm analysis areas, the thunderstorm characteristic analysis results for each thunderstorm analysis area can be carried out according to the above-mentioned analysis process, which will not be elaborated here.

[0064] In the above embodiment, when analyzing the thunderstorm characteristics of the transmission area, the thunderstorm analysis area within the transmission area is first determined based on the characteristic analysis signal of the area, and then the instantaneous increase in the ground flash frequency corresponding to the thunderstorm in the thunderstorm analysis area, the average probability of the lightning current amplitude in each area in the thunderstorm analysis area, and the average duration period of thunderstorm weather in the thunderstorm analysis area are obtained through the meteorological data of the meteorological station. In this way, the thunderstorm characteristic analysis coefficient within the thunderstorm analysis area generated can be more accurate, thereby effectively improving the accuracy of the thunderstorm characteristic analysis results of the thunderstorm analysis area.

[0065] In one embodiment, the regional characteristic analysis unit generates a calculation formula for the thunderstorm characteristic analysis coefficient in the thunderstorm analysis area based on the instantaneous growth amount, the average probability of the lightning current amplitude in each area, and the average duration period of thunderstorm weather in the thunderstorm analysis area: G = DS × v1 + GL × v2 + CZ × v3

[0066] Where G is the thunderstorm characteristic analysis coefficient within the thunderstorm analysis area, DS is the instantaneous increase in the ground-to-ground flash frequency corresponding to thunderstorms within the thunderstorm analysis area, GL is the average probability of lightning current amplitude in each area within the thunderstorm analysis area, CZ is the average duration of thunderstorm weather within the thunderstorm analysis area, v1, v2, and v3 are all preset proportional coefficients, and v1>v2>v3>0.

[0067] It can be understood that the above formulas are obtained by collecting a large amount of data and performing software simulation, and a formula close to the actual value is selected. The coefficients in the formula can be set by those skilled in the art according to actual conditions and are not limited here.

[0068] In the above embodiment, the thunderstorm characteristic analysis coefficient can be quickly calculated using the calculation formula of the thunderstorm characteristic analysis coefficient in the thunderstorm analysis area, thereby effectively improving the calculation efficiency of the thunderstorm characteristic analysis result.

[0069] In one embodiment, the process of determining the thunderstorm characteristic analysis result of the thunderstorm analysis area according to the thunderstorm characteristic analysis coefficient by the regional characteristic analysis unit may include:

[0070] The regional characteristic analysis unit compares the thunderstorm characteristic analysis coefficient with a preset thunderstorm characteristic analysis coefficient threshold.

[0071] When the regional characteristic analysis unit determines that the thunderstorm characteristic analysis coefficient exceeds the thunderstorm characteristic analysis coefficient threshold, the regional characteristic analysis unit determines that the thunderstorm characteristic in the thunderstorm analysis area is a high-impact characteristic.

[0072] When the regional characteristic analysis unit determines that the thunderstorm characteristic analysis coefficient does not exceed the thunderstorm characteristic analysis coefficient threshold, the regional characteristic analysis unit determines that the thunderstorm characteristic in the thunderstorm analysis area is a low-impact characteristic.

[0073] In this embodiment, when the regional characteristic analysis unit determines the thunderstorm characteristic analysis result of the thunderstorm analysis area based on the thunderstorm characteristic analysis coefficient, it can first compare the thunderstorm characteristic analysis coefficient with a preset thunderstorm characteristic analysis coefficient threshold, and when the thunderstorm characteristic analysis coefficient exceeds the thunderstorm characteristic analysis coefficient threshold, it is determined that the thunderstorm characteristics in the thunderstorm analysis area are high-impact characteristics; when the thunderstorm characteristic analysis coefficient does not exceed the thunderstorm characteristic analysis coefficient threshold, it is determined that the thunderstorm characteristics in the thunderstorm analysis area are low-impact characteristics. In this way, the thunderstorm characteristic analysis result of the thunderstorm analysis area can be determined.

[0074] In the above embodiment, by comparing the thunderstorm characteristic analysis coefficient with the thunderstorm characteristic analysis coefficient threshold, it can be quickly determined whether the thunderstorm characteristic in the thunderstorm analysis area is a high-impact characteristic or a low-impact characteristic, thereby effectively improving analysis efficiency.

[0075] In one embodiment, the thunderstorm characteristic analysis results include a thunderstorm analysis area with high-impact characteristics and a thunderstorm analysis area with low-impact characteristics. The thunderstorm analysis area is an area within the transport area where thunderstorms exist.

[0076] The process of the transmission platform formulating the power transmission strategy for the transmission area according to the thunderstorm characteristic analysis result may include:

[0077] When the transmission platform determines that the thunderstorm characteristic analysis result is a thunderstorm analysis area with high-impact characteristics, it performs thunderstorm prediction on the thunderstorm analysis area with high-impact characteristics, and after determining the thunderstorm prediction time period based on the thunderstorm prediction result, reduces the power transmission amount within the thunderstorm prediction time period to the minimum value.

[0078] When the transmission platform determines that the thunderstorm characteristic analysis result is a thunderstorm analysis area with low-impact characteristics, it determines whether the power transmission amount of the thunderstorm analysis area with high-impact characteristics in the transmission area has dropped to the minimum value during the thunderstorm prediction time period, and when the power transmission amount cannot be dropped to the minimum value, the power transmission route of the thunderstorm analysis area with high-impact characteristics is temporarily transferred to the thunderstorm analysis area with low-impact characteristics.

[0079] In this embodiment, if the thunderstorm characteristic analysis coefficient in the thunderstorm analysis area exceeds the thunderstorm characteristic analysis coefficient threshold, the thunderstorm characteristic in the thunderstorm analysis area is determined to be a high-impact characteristic, a high-impact signal is generated and the high-impact signal is sent to the transmission platform. After the transmission platform receives the high-impact signal and the corresponding thunderstorm analysis area, it will perform thunderstorm prediction on the thunderstorm analysis area during the power transmission process, and after obtaining the predicted time period, it will reduce the power transmission amount in the predicted time period to the minimum through transmission progress adjustment, so as to avoid being affected by thunderstorm weather in the thunderstorm analysis area, resulting in reduced power transmission safety and directly hindering the progress of power transmission.

[0080] If the thunderstorm characteristic analysis coefficient in the thunderstorm analysis area does not exceed the thunderstorm characteristic analysis coefficient threshold, the thunderstorm characteristic in the thunderstorm analysis area is determined to be a low-impact characteristic, a low-impact signal is generated and sent to the transmission platform. After the transmission platform receives the low-impact signal and the corresponding thunderstorm analysis area, when the transmission progress adjustment cannot reduce the power transmission amount in the high-impact thunderstorm analysis area to the minimum, the current power transmission route can be temporarily transferred, and the current thunderstorm analysis area with low-impact characteristics can be used as a transfer area and as a temporary passage area for the current task execution, so as to reduce the impact of thunderstorm weather on the thunderstorm analysis area with high-impact characteristics.

[0081] In one embodiment, the thunderstorm characteristic analysis result includes a thunderstorm analysis area where thunderstorms exist within the delivery area.

[0082] The process of the transmission impact analysis unit performing a thunderstorm impact analysis on the impact of thunderstorms on the real-time power transmission process of the transmission platform according to the transmission impact analysis signal and the thunderstorm characteristic analysis result, and obtaining the thunderstorm impact analysis result may include:

[0083] The transmission impact analysis unit determines the tripping frequency of the switching device in the thunderstorm analysis area during the real-time power transmission process and the continuously increasing span of the ground lightning starting height in the thunderstorm analysis area based on the transmission impact analysis signal and the thunderstorm characteristic analysis result, and determines the power transmission impact result of the real-time power transmission process in the thunderstorm analysis area affected by the thunderstorm based on the tripping frequency of the switching device and the continuously increasing span of the ground lightning starting height.

[0084] In this embodiment, when the transmission impact analysis unit performs thunderstorm impact analysis on the real-time power transmission process of the transmission platform affected by thunderstorms, it can first determine the tripping frequency of the switching equipment in the thunderstorm analysis area during the real-time power transmission process, and the continuously increasing span of the ground lightning starting height in the thunderstorm analysis area based on the transmission impact analysis signal and the thunderstorm characteristic analysis results. In this way, the power transmission impact results of the real-time power transmission process in the thunderstorm analysis area affected by thunderstorms can be determined based on the tripping frequency of the switching equipment and the continuously increasing span of the ground lightning starting height, thereby effectively improving the analysis accuracy and analysis efficiency of the power transmission impact results.

[0085] In one embodiment, the process of determining, by the transmission impact analysis unit, the power transmission impact result of the real-time power transmission in the thunderstorm analysis area being affected by the thunderstorm based on the tripping frequency of the switchgear and the continuously increasing span of the ground lightning starting height, may include:

[0086] The transmission impact analysis unit compares the tripping frequency of the switchgear with a preset tripping frequency threshold, and compares the continuous increase span of the ground lightning starting height with a preset height increase span threshold.

[0087] When the transmission impact analysis unit determines that the tripping frequency of the switching device exceeds the tripping frequency threshold or the continuous increase span of the ground lightning starting height exceeds the height increase span threshold, it determines that the real-time power transmission in the thunderstorm analysis area is affected by the power transmission process affected by the thunderstorm as being affected.

[0088] When the transmission impact analysis unit determines that the tripping frequency of the switching device does not exceed the tripping frequency threshold and the continuous increase span of the ground lightning starting height does not exceed the height increase span threshold, it determines that the real-time power transmission in the thunderstorm analysis area is not affected by the power transmission process affected by the thunderstorm.

[0089] In this embodiment, when determining the power transmission impact result of the real-time power transmission in the thunderstorm analysis area being affected by the thunderstorm, the transmission impact analysis unit may compare the tripping frequency of the switch device with a preset tripping frequency threshold, and compare the continuous increase span of the ground lightning starting height with a preset height increase span threshold. If the tripping frequency of the switch device exceeds the tripping frequency threshold and the continuous increase span of the ground lightning starting height exceeds the height increase span threshold, then the power transmission process impact result of the real-time power transmission in the thunderstorm analysis area being affected by the thunderstorm is determined to be affected. If the tripping frequency of the switch device does not exceed the tripping frequency threshold and the continuous increase span of the ground lightning starting height does not exceed the height increase span threshold, then the power transmission impact result of the real-time power transmission in the thunderstorm analysis area being affected by the thunderstorm is determined to be unaffected. This process can quickly determine whether the real-time power transmission process in the thunderstorm analysis area is affected by the thunderstorm by comparing the tripping frequency of the switch device with the tripping frequency threshold and the continuous increase span of the ground lightning starting height with the height increase span threshold.

[0090] In one embodiment, the thunderstorm impact analysis result includes whether the real-time power transmission process in a thunderstorm analysis area is affected by thunderstorms and whether it is not affected by thunderstorms. The thunderstorm analysis area is an area within the transmission area where thunderstorms exist.

[0091] The process of the transmission platform determining whether to adjust the power transmission strategy according to the thunderstorm impact analysis result may include:

[0092] When determining that the real-time power transmission process in the thunderstorm analysis area is affected by a thunderstorm, the transmission platform adjusts the power transmission amount and transmission time related to the thunderstorm analysis area in the power transmission strategy.

[0093] When the transmission platform determines that the real-time power transmission process in the thunderstorm analysis area is not affected by the thunderstorm, there is no need to adjust the power transmission strategy.

[0094] In this embodiment, if the tripping frequency of the transmission switch equipment in the thunderstorm analysis area exceeds the tripping frequency threshold during power transmission, or the continuous increase span of the lightning starting height in the thunderstorm analysis area exceeds the height increase span threshold, it is determined that the current power transmission process in the thunderstorm analysis area is affected, and a power transmission impact signal is generated and sent to the transmission platform. The transmission platform will adjust the transmission volume and transmission time corresponding to the transmission task of the thunderstorm analysis area.

[0095] If the tripping frequency of the transmission switchgear in the thunderstorm analysis area during power transmission does not exceed the tripping frequency threshold, and the continuous increase span of the lightning starting height in the thunderstorm analysis area does not exceed the height increase span threshold, it is determined that the current power transmission process in the thunderstorm analysis area is not affected, and a power transmission safety signal is generated and sent to the transmission platform.

[0096] In the above embodiment, by comparing the tripping frequency of the transmission switchgear with the tripping frequency threshold, and the continuously increasing span of the starting height of the lightning in the thunderstorm analysis area with the height increase span threshold, it is possible to quickly determine whether the real-time power transmission process in the thunderstorm analysis area is affected by the thunderstorm, and adjust the power transmission strategy in time when affected by the thunderstorm, thereby effectively reducing the safety hazards caused by the impact of thunderstorms and improving the safety of power transmission.

[0097] In one embodiment, as shown in FIG2 , FIG2 is a structural diagram of another thunderstorm area power transmission safety monitoring system provided in an embodiment of the present application; the system may further include an early warning unit.

[0098] The transmission platform is further configured to send a monitoring warning signal related to the power transmission strategy to the warning unit after receiving a transmission impact analysis completion instruction sent by the transmission impact analysis unit.

[0099] The early warning unit is used to receive the monitoring early warning signal, and based on the monitoring early warning signal, perform safety monitoring and early warning on the process of the transmission platform performing real-time power transmission to the power demand end in accordance with the power transmission strategy, and send the monitoring and early warning results to the transmission platform so that the transmission platform can determine whether to adjust the power transmission strategy.

[0100] In this embodiment, after receiving the transmission impact analysis completion instruction sent by the transmission impact analysis unit, the transmission platform can generate a monitoring warning signal according to a pre-configured monitoring warning signal generation method and send the monitoring warning signal to the warning unit. After the warning unit receives the monitoring warning signal, it monitors and warns the thunderstorm analysis area during the power transmission process to prevent the real-time characteristics of the thunderstorm analysis area from deviating from the predicted characteristics during the transmission process, causing safety problems in the power transmission in the thunderstorm analysis area and affecting the qualification of the power transmission.

[0101] Specifically, the early warning unit itself can conduct safety monitoring and early warning on the process of the transmission platform transmitting power to the power demand end in real time according to the power transmission strategy based on the monitoring early warning signal, and send the monitoring and early warning results to the transmission platform so that the transmission platform can determine whether to adjust the power transmission strategy, thereby improving the safety and stability of power transmission.

[0102] In one embodiment, the power transmission strategy includes reducing the power transmission amount in a thunderstorm analysis area having high-impact characteristics to a minimum value during a thunderstorm prediction period, wherein the thunderstorm analysis area is an area within the transmission area where thunderstorms occur.

[0103] The early warning unit performs safety monitoring and early warning on the process of the transmission platform transmitting power to the power demand end in real time according to the power transmission strategy according to the monitoring and early warning signal, and sends the monitoring and early warning result to the transmission platform so that the transmission platform can determine whether to adjust the power transmission strategy. The process may include:

[0104] The early warning unit determines the start and end time points of the thunderstorm weather in the thunderstorm analysis area and the preset start and end time points of the thunderstorm prediction time period, the predicted thunderstorm characteristic parameters of the thunderstorm analysis area, and the actual thunderstorm characteristic parameters according to the monitoring early warning signal.

[0105] The early warning unit calculates the time deviation between the start and end time points of the thunderstorm weather and the preset start and end time points, or the numerical deviation between the predicted thunderstorm characteristic parameters and the actual thunderstorm characteristic parameters, and compares the time deviation with a preset time deviation threshold, and compares the numerical deviation with a preset numerical deviation threshold.

[0106] When the warning unit determines that the time deviation exceeds the time deviation threshold, or the numerical deviation exceeds the numerical deviation threshold, it generates a sudden warning signal and sends the sudden warning signal to the conveying platform, so that the conveying platform can adjust or pause the conveying task in the current conveying circuit and monitor the conveying equipment in real time during continuous conveying.

[0107] When determining that the time deviation does not exceed the time deviation threshold and the numerical deviation does not exceed the numerical deviation threshold, the warning unit generates a no-warning signal and sends the no-warning signal to the conveying platform.

[0108] In this embodiment, after obtaining the deviation between the start and end time points of the thunderstorm weather in the thunderstorm analysis area and the preset start and end time points, as well as the numerical deviation between the predicted thunderstorm characteristic parameters of the thunderstorm weather in the thunderstorm analysis area and the actual thunderstorm characteristic parameters, the early warning unit can compare the deviation between the start and end time points of the thunderstorm weather in the thunderstorm analysis area and the preset start and end time points, as well as the numerical deviation between the predicted thunderstorm characteristic parameters of the thunderstorm weather in the thunderstorm analysis area and the actual thunderstorm characteristic parameters with a time deviation threshold and a numerical deviation threshold, respectively. The thunderstorm characteristic parameters here represent parameters of the thunderstorm weather in the thunderstorm analysis area, such as the spatiotemporal variation of thunderstorms, ground-to-ground lightning density, lightning current amplitude, and other parameters.

[0109] If the deviation between the start and end time points of the thunderstorm weather in the thunderstorm analysis area and the preset start and end time points exceeds the time deviation threshold, or the numerical deviation between the predicted thunderstorm characteristic parameters of the thunderstorm weather in the thunderstorm analysis area and the actual thunderstorm characteristic parameters exceeds the numerical deviation threshold, an early warning will be issued for the power transmission in the thunderstorm analysis area, and a sudden early warning signal will be generated and sent to the transmission platform. After receiving the sudden early warning signal, the transmission platform will adjust or suspend the transmission task in the current transmission circuit, and conduct real-time monitoring of the transmission equipment during continuous transmission.

[0110] If the deviation between the start and end time points of the thunderstorm weather in the thunderstorm analysis area and the preset start and end time points does not exceed the time deviation threshold, and the numerical deviation between the predicted thunderstorm characteristic parameters of the thunderstorm weather in the thunderstorm analysis area and the actual thunderstorm characteristic parameters does not exceed the numerical deviation threshold, then there will be no early warning for power transmission in the thunderstorm analysis area, and a no-warning signal will be generated and sent to the transmission platform.

[0111] In the above embodiment, the early warning unit can determine whether to generate a sudden early warning signal or no early warning signal based on whether the deviation between the start and end time points of the thunderstorm weather in the thunderstorm analysis area and the preset start and end time points exceeds the time deviation threshold, or whether the numerical deviation between the predicted thunderstorm characteristic parameters of the thunderstorm weather in the thunderstorm analysis area and the actual thunderstorm characteristic parameters exceeds the numerical deviation threshold, thereby giving an accurate early warning signal.
