[0044] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0045] The risk warning method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. The server 104 can obtain the off-site protection alarm data and the station recording data of the target distribution station in the target period from the data storage system; then, the index data of the off-site risk index can be extracted from the off-site protection alarm data, and the index data of the station risk index can be extracted from the station recording data; and according to the index data of the off-site risk index and the index data of the station risk index, the target distribution station is warned of risk, and the risk warning information is sent to the terminal 102, and the terminal 102 displays the risk warning information. Among them, the terminal 102 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices, and the Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The server 104 may be implemented as an independent server or a server cluster consisting of multiple servers.

[0046] In an exemplary embodiment, Figure 2 As shown, a risk early warning method is provided, which is applied to Figure 1 Taking the server 104 in the example as an example, the following steps may be included:

[0047] S201, obtaining off-station protection alarm data and on-station recording data of a target distribution station within a target period of time.

[0048] Among them, the target time period can represent a specific time period or period, such as the period between the current time point and the past 1 hour; the off-site protection alarm data can represent the alarm information and other data generated when the protection device or safety equipment detects potential security threats or abnormal behaviors, such as protection action time, action type and fault phase information; the in-station recording data can represent the waveform data and numerical data of electrical parameters such as the current and voltage of the line.

[0049] Exemplarily, the server 104 can directly obtain the off-station protection alarm data and the on-station recording data of the target distribution station in the target period through the data storage system. Optionally, the off-station protection alarm data can be collected by a protection device installed outside the target distribution station, and the on-station recording data can be collected by a recording device installed outside the target distribution station.

[0050] S202, extracting index data of off-site risk indexes from off-site protection alarm data, and extracting index data of on-site risk indexes from on-site recording data.

[0051] Among them, the off-station risk index can represent the quantitative standard that can measure the degree of risk that the target distribution station may face from the dimension of protection devices, such as the number of protection actions and the time difference between adjacent protection actions; the on-station risk index can represent the quantitative standard that can measure the degree of risk that the target distribution station may face from the dimension of electrical parameters, such as current, voltage effective value, change rate and harmonic content.

[0052] For example, the number of protection actions within the target period can be counted from the off-site protection alarm data to determine the index data of the number of protection actions in the off-site risk index, and the time difference between adjacent protection actions within the target period can be calculated to determine the index data of the time difference between adjacent protection actions in the off-site risk index; data analysis algorithms (such as classification algorithms, clustering algorithms, and regression algorithms, etc.) can be used to extract index data of in-station risk indicators such as the effective value, change rate, and harmonic content of current and voltage from the in-station recorded data.

[0053] S203, issuing risk warning to the target distribution station according to the indicator data of the off-station risk indicator and the indicator data of the on-station risk indicator.

[0054] Among them, risk warnings may include but are not limited to risk warning reports, alarm sounds, and warning window reminders.

[0055] For example, a reasonable warning threshold can be set for each risk indicator (off-site risk indicators and on-site risk indicators) based on historical data and expert experience; the indicator data of each risk indicator can be compared with the corresponding warning threshold to determine the number of risk indicators whose indicator data is greater than the corresponding warning threshold. If the risk indicator whose indicator data is greater than the corresponding warning threshold exceeds the indicator threshold, a warning signal is triggered to remind relevant personnel to take corresponding measures.

[0056] The above-mentioned risk warning method provides a data basis for multi-dimensional assessment of the risk status of the target distribution station by obtaining the off-site protection alarm data and the in-station recording data of the target distribution station in the target period; further, the index data of the off-site risk indicators are extracted from the off-site protection alarm data, and the index data of the in-station risk indicators are extracted from the in-station recording data, which lays the foundation for accurate risk warning; then, the target distribution station can be given a risk warning based on the index data of the off-site risk indicators and the index data of the in-station risk indicators. This scheme provides a data basis for a comprehensive analysis of the risk status of the target distribution station by introducing off-site protection alarm data and in-station recording data; furthermore, by extracting the index data of the risk indicators, it provides ideas for screening effective information and ultimately achieves accurate risk warning.

[0057] Based on the above embodiment, the embodiment of the present application explains the above embodiment S201 in detail. Specifically, the embodiment of the present application involves the process of obtaining the off-site protection alarm data and the on-site recording data of the target distribution station in the target period, which specifically includes: obtaining the off-site protection alarm data of the target distribution station in the target period through the protection device of the target distribution station; and obtaining the on-site recording data of the target distribution station in the target period through the recording device of the target distribution station.

[0058] Exemplarily, the off-site protection alarm data of the target distribution station can be collected in real time through various protection devices and safety equipment of the target distribution station, and the collected data can be processed by data cleaning and format conversion to ensure high quality and unified representation of the data, and finally the processed data can be saved to the data storage system; and the recording data of the target distribution station can be collected in real time through the recording equipment or recording device in the target distribution station, and the collected data can be processed by data cleaning and format conversion to ensure high quality and unified representation of the data, and finally the processed data can be saved to the data storage system; furthermore, the server 104 can directly obtain the off-site protection alarm data and in-station recording data of the target distribution station within the target period through the data storage system.

[0059] In the embodiment of the present application, by introducing protection devices and recording equipment, a way is provided for obtaining off-site protection alarm data and on-site recording data, laying the foundation for achieving accurate risk warning.

[0060] Based on the above embodiment, the present application embodiment explains the above embodiment S203 in detail. Specifically, the present application embodiment involves a process of performing risk warning on a target distribution station, such as Figure 3 As shown, the specific steps include:

[0061] S301, determining a target risk index corresponding to a target distribution station according to the indicator data of an off-station risk indicator and the indicator data of an on-station risk indicator.

[0062] Among them, the target risk index can indicate the degree of risk that the target distribution station may face.

[0063] An implementable method is to determine a first risk index corresponding to a target distribution station based on indicator data of an off-station risk indicator, and to determine a second risk index corresponding to the target distribution station based on indicator data of an on-station risk indicator; to perform a weighted summation of the first risk index and the weight corresponding to the first risk index to obtain an off-station risk index, and to perform a weighted summation of the second risk index and the weight corresponding to the second risk index to obtain an on-station risk index; and to determine a target risk index corresponding to the target distribution station based on the off-station risk index and the on-station risk index.

[0064] Optionally, each risk indicator (off-site risk indicator and on-site risk indicator) can correspond to a different indicator weight respectively. The indicator weight corresponding to each risk indicator can be determined based on actual experience and expert knowledge. For example, a risk indicator with a stronger correlation with substation risk (which can be determined by correlation calculation and / or expert experience) has a larger indicator weight value, so as to distinguish the differences between the risk indicators; furthermore, the degree of influence of off-site protection alarm data and on-site recording data on distribution station risks is also different, which can also be distinguished by weight, that is, by the weight corresponding to the first risk index and the weight corresponding to the second risk index.

[0065] Exemplarily, the indicator data of the off-site risk indicator and the indicator weights corresponding to each off-site risk indicator can be weighted summed, and the first risk index P1 corresponding to the target distribution station can be determined according to the result of the weighted summation, and the indicator data of the on-site risk indicator and the indicator weights corresponding to each on-site risk indicator can be weighted summed, and the second risk index P2 corresponding to the target distribution station can be determined according to the result of the weighted summation; further, the product of the first risk index P1 and the weight Z1 corresponding to the first risk index is determined as the off-site risk index P 外 The product of the second risk index P2 and the weight Z2 corresponding to the second risk index is determined as the in-station risk index P 内 ; Then, the off-site risk index P 外 and the risk index P 内 The sum is added and determined as the target risk index corresponding to the target distribution station.

[0066] Another possible implementation method is to input the index data of off-site risk indicators and the index data of on-site risk indicators into a risk index determination model, which analyzes and processes the index data of off-site risk indicators and the index data of on-site risk indicators and determines the target risk index corresponding to the target distribution station.

[0067] S302: Issue a risk warning to the target distribution station according to the relationship between the target risk index corresponding to the target distribution station and the target risk threshold.

[0068] The target risk threshold can be preset according to the maximum risk level that the target distribution station can accept.

[0069] Exemplarily, after determining the target risk index corresponding to the target distribution station, a risk warning report corresponding to the target distribution station can be generated; further, the target risk index and the target risk threshold can be compared in size, and the form of risk warning can be determined based on the comparison result.

[0070] A feasible method is to generate a risk warning report for a target distribution station; if a target risk index corresponding to the target distribution station is greater than a target risk threshold, obtain a risk warning report of an associated distribution station of the target distribution station during a target period; update the risk warning report of the target distribution station according to the risk warning report of the associated distribution station during the target period; and output the updated risk warning report.

[0071] Among them, the associated substations can determine other substations associated with the target substation based on factors such as geographical location, grid connection and equipment type.

[0072] For example, the indicator data of each risk indicator (off-site risk indicators and on-site risk indicators), the indicator standard value of each risk indicator (which can be determined based on historical indicator data), the target risk index, suspected faulty equipment and countermeasures and other information can be statistically analyzed through the risk warning report; further, when the target risk index corresponding to the target distribution station is greater than the target risk threshold, it is characterized that the probability of failure of the target distribution station is relatively high. In order to make an accurate risk warning, more information can be obtained from the associated distribution stations of the target distribution station, that is, the risk warning report of the associated distribution stations of the target distribution station in the target period is obtained, and the information in the risk warning report of the associated distribution station in the target period is compared with the information in the risk warning report of the target distribution station to determine the direction and location of the fault and other information, and the risk warning report of the target distribution station is updated to present a more accurate risk warning report to the staff, so as to discover the source of the abnormality more quickly and troubleshoot the fault as soon as possible.

[0073] It should be noted that the target risk threshold is determined in the following way: based on the reference risk index of the target distribution station in the comparison period, the initial risk threshold of the target distribution station in the target period is determined; based on the configuration update of the target distribution station in the target period, the risk adjustment coefficient is determined; and the initial risk threshold is adjusted using the risk adjustment coefficient to obtain the target risk threshold of the target distribution station in the target period.

[0074] Among them, the comparison period can be a period that can be used as a reference for the target period. For example, if the target period is 13:00-15:00 of the target distribution station today, the comparison period can be the period from 13:00 to 15:00 of the target distribution station in the past month; the initial risk threshold can represent the risk threshold determined based on the data of the target distribution station within the comparison period; the configuration update situation can include equipment updates of the target distribution station, etc.; the risk adjustment coefficient can represent the change in the probability of a failure event caused by a configuration update of the target distribution station.

[0075] Exemplarily, the reference risk index of the target distribution station in the comparison period can be directly determined as the initial risk threshold of the target distribution station in the target period; further, the initial risk threshold can be adaptively adjusted according to the configuration update of the target distribution station in the target period to adapt to the condition of the target distribution station in the target period, that is, the risk adjustment coefficient can be determined according to the configuration update of the target distribution station in the target period; further, the risk adjustment coefficient can be multiplied by the initial risk threshold, and the product can be determined as the target risk threshold of the target distribution station in the target period.

[0076] In the embodiment of the present application, by introducing a target risk threshold, a standard is provided for determining the status of a target distribution station within a target period of time, and a basis is provided for determining the form of risk warning.

[0077] Based on the above embodiment, this embodiment provides an optional example of a risk warning method. Figure 4 As shown, the specific implementation process is as follows:

[0078] S401, obtaining off-site protection alarm data and on-site recording data of a target distribution station within a target period of time.

[0079] Optionally, the off-site protection alarm data of the target distribution station in the target time period is obtained through the protection device of the target distribution station; and the on-site recording data of the target distribution station in the target time period is obtained through the recording equipment of the target distribution station.

[0080] S402, extracting index data of off-site risk indexes from off-site protection alarm data, and extracting index data of on-site risk indexes from on-site recording data.

[0081] S403, determining a first risk index corresponding to the target distribution station according to the indicator data of the off-station risk indicator, and determining a second risk index corresponding to the target distribution station according to the indicator data of the on-station risk indicator.

[0082] S404, performing weighted summation on the first risk index and the weight corresponding to the first risk index to obtain an off-site risk index, and performing weighted summation on the second risk index and the weight corresponding to the second risk index to obtain an on-site risk index.

[0083] S405: Determine a target risk index corresponding to the target distribution station according to the off-station risk index and the on-station risk index.

[0084] S406, generating a risk warning report for the target distribution station; if the target risk index corresponding to the target distribution station is greater than the target risk threshold, obtaining a risk warning report of the distribution stations associated with the target distribution station in the target period.

[0085] Among them, the target risk threshold is determined in the following way: according to the reference risk index of the target distribution station in the comparison period, the initial risk threshold of the target distribution station in the target period is determined; based on the configuration update of the target distribution station in the target period, the risk adjustment coefficient is determined; the initial risk threshold is adjusted by using the risk adjustment coefficient to obtain the target risk threshold of the target distribution station in the target period.

[0086] S407, updating the risk warning report of the target distribution station according to the risk warning report of the associated distribution station in the target period.

[0087] S408, outputting an updated risk warning report.

[0088] The specific process of S401-S408 above can refer to the description of the above method embodiment, and its implementation principle and technical effect are similar, which will not be repeated here.
