[0053] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The enumerated embodiments are only used to explain the present invention and are not used to limit the scope of the present invention.

[0054] Reference Figure 1 This embodiment provides a method for analyzing the impact of equipment failure, the method comprising the following steps:

[0055] S101. Obtaining information about failed equipment in a power grid.

[0056] Exemplarily, the acquisition of information on failed power grid equipment mainly includes two methods: online monitoring and offline testing. Among them, online monitoring can be to detect the temperature distribution on the surface of the equipment through an infrared camera to effectively find overheated parts; or vibration monitoring of rotating machinery (such as generators, transformer fans, etc.) can help identify problems such as imbalance and misalignment. Online monitoring includes but is not limited to temperature monitoring, partial discharge monitoring, insulation performance monitoring, etc. By installing sensors, various parameters of equipment operation can be collected in real time to detect abnormal conditions in time. Offline testing is carried out when the equipment is shut down, mainly including withstand voltage testing, insulation resistance testing, dielectric loss factor measurement, etc. This type of test can provide a more in-depth assessment of the health status of the equipment, such as detecting material defects or structural damage by capturing the weak sound waves generated inside the equipment, which is suitable for monitoring high-voltage switchgear, etc.; and for equipment with oil cooling or insulation systems (such as transformers), the condition inside the equipment can be judged by analyzing the oil quality. Through online monitoring and offline testing, failed power grid equipment can be effectively discovered and relevant information about these failed power grid equipment can be obtained.

[0057] In this embodiment, the power grid failed device information includes at least the failed device type, failed device capacity, failed device access mode and other information.

[0058] S102. Based on the information of failed power grid equipment, analyze the impact of power grid equipment failure from multiple dimensions to obtain analysis results, wherein the analysis results at least include analysis results of the impact of power grid equipment failure on finance, analysis results of the impact on personal safety, analysis results of the impact on the environment, and analysis results of the impact on the power grid.

[0059] S103. Based on the analysis results of all dimensions, calculate the total impact of the current power grid equipment failure and predict the impact of future power grid equipment failure.

[0060] As an optional implementation, the impact of power grid equipment failure is analyzed from multiple dimensions, including the impact of power grid equipment failure from a financial dimension. The financial impact of power grid equipment failure only needs to consider the maintenance and replacement costs of power grid equipment, that is, for a certain failure mode, the cost of manpower, accessories, machinery, consumables, etc. required to restore it to the state before failure. The overall calculation process is as follows Figure 2 As shown, the specific operations include the following:

[0061] S201. Determine the device type, device capacity and device access method according to the failed device information of the power grid.

[0062] S202. Determine the financial impact factor of the equipment capacity type according to the equipment type and equipment capacity.

[0063] In this optional implementation, different equipment types and different equipment capacities correspond to different equipment capacity type financial impact factors. For example, Table 1 shows the equipment capacity type financial impact factors corresponding to different capacities of 220kV oil-immersed transformers.

[0067] In this optional implementation, the same equipment has different accessibility when it is set at different locations. The default value of the equipment accessibility financial factor is 1, the value of a restricted channel or restricted workspace is 1.1, and the value of an underground substation is 1.25.

[0068] S204, calculating the maintenance and replacement impact factor according to the equipment capacity type financial impact factor and the equipment accessibility financial factor. The calculation formula is: maintenance and replacement impact factor = equipment capacity type financial impact factor × equipment accessibility financial factor.

[0069] S205. Query the cost reference value of the financial impact of failure of similar equipment in a specified historical period according to the equipment type, and obtain the reference value of the repair and replacement impact.

[0071] S206, calculating the maintenance replacement impact value through the maintenance replacement impact factor and the maintenance replacement impact reference value, and writing the maintenance replacement impact value into the analysis result of the impact of power grid equipment failure on finance.

[0075] In this optional implementation, the costs and related quotas for operation and maintenance, inspections, repairs, and testing of a certain type of power grid equipment over the past 10 years can be sorted out to obtain a cost reference value for the impact of failure of this type of equipment on personal safety, which can be used as a reference value for the impact on personal safety.

[0076] S303: Determine a personal safety adaptation factor according to the device type.

[0077] In this optional implementation, different types of equipment correspond to different personal safety adaptation factors.

[0082] In this optional implementation, the value of the personal safety factor is determined by a personal safety factor evaluation matrix composed of a location safety factor and a type safety factor. The content of the personal safety factor evaluation matrix corresponding to different types of equipment is different. For example, Table 3 shows a personal safety factor evaluation matrix for a transformer type of equipment.

[0083] Table 3

[0084]

[0085] S305. Calculate the personal safety impact factor through the personal safety adaptation factor and the personal safety factor, then calculate the personal safety impact value through the personal safety impact factor and the personal safety impact reference value, and write the personal safety impact value into the analysis result of the impact of power grid equipment failure on personal safety.

[0086] Exemplarily, the calculation formula of the personal safety impact factor is: personal safety impact factor=personal safety factor×personal safety adaptation factor. The calculation formula of the personal safety impact value is: personal safety impact value=personal safety impact reference value×personal safety impact factor.

[0087] As an optional implementation, the impact of power grid equipment failure is analyzed from multiple dimensions, including the environmental dimension.

[0096] S405, calculating the environmental impact factor through the equipment type factor value, the equipment capacity type impact factor, and the environmental location factor. The calculation formula is: environmental impact factor = equipment type factor × equipment capacity type impact factor × environmental location factor.

[0097] S406, calculate the environmental safety impact value through the environmental impact factor and the environmental impact reference value, and write the environmental safety impact value into the environmental impact analysis result of the power grid equipment failure. The calculation formula of the environmental safety impact value is: environmental safety impact value = environmental impact reference value × environmental impact factor.
