Embodiment 1

[0055] This embodiment provides a risk assessment method based on RPN-based power metering equipment, please see figure 1 This method includes:

[0056] First, step S1 is performed: Based on the RPN method to analyze the fault type and fault impact of the power metering device, determine the evaluation index of the power metering device, where the evaluation indicators include fault occurrence probability, personnel factors, system functional factors, maintenance time factors, Maintenance cost factors.

[0057] Specifically, the RPN (RiskPriorityNumber) refers to the frequency, severity and detection level of the event. It is called a risk factor or the number of risk sequence, and the more potential problems are more serious, and it is used to measure possible process defects. To take possible preventive measures to reduce key process changes to make the process more reliable. In the present invention, the method based on the type of fault and parameters and faults are analyzed b...

Embodiment 2

[0105] This embodiment provides an RPN-based power metering equipment risk assessment device, please see image 3 The device includes:

[0106] Evaluation Index Determination Module 301, for analyzing the fault type and fault impact of the power metering device based on the RPN method, determines the evaluation index of the power metering device, wherein the evaluation indicators include fault occurrence probability, personnel factors, system functional factors, Maintenance factor and maintenance cost factors;

[0107] The rating determination module 302 is used to use a hierarchical cause analysis according to the level of the power metering device, and the level of each evaluation index is determined;

[0108] The weight determination module 303 is used to determine the weight of each evaluation index based on AHP-based hierarchical analysis;

[0109] Model Building Module 304 for constructing a fault mode risk assessment model according to the level and weight of each evaluation...

Embodiment 3

[0131] Based on the same inventive concept, the present application also provides a computer readable storage medium 400, please see Figure 4 The computer program 411 is stored on it, and the method is implemented when the program is executed.

Abstract

The present invention provides a risk assessment method and device for power metering equipment based on RPN, wherein the method analyzes factors of failure types and parameters, failure effects and failure causes of on-site metering equipment, mainly involving personnel environment, system function, maintenance The degree of influence of the four aspects of time and maintenance costs, and then construct the weight of the evaluation factors based on AHP, and finally carry out the risk evaluation of the power metering equipment. At the same time, the method of the invention can provide guidance for the maintenance of electric metering equipment. It solves the problem of inaccurate evaluation results caused by various types, huge quantities, and complex operating conditions of power metering equipment. The technical effects of improving the accuracy of the evaluation results and realizing the division of risk levels are realized.

Description

Technical field [0001] The present invention relates to the field of data mining technology in computer discipline, and more particularly to a Risk assessment method and apparatus based on RPN-based power metering equipment. Background technique [0002] The State Grid Corporation has started the construction of electricity information collection system in 2010, accumulating a lot of data on metering equipment. However, there are many types of metering equipment, the number, the operational condition is complex, and the abnormal discovery and analysis is manually derived by the operation and maintenance personnel, and the artificial analysis is completely dependent on the experience of the operator. Therefore, using multiple database data, data mining technology is used to have theoretical and practical significance for warning and risk prediction of safety hazards in transport equipment. [0003] At present, the risk of equipment operation has always been a hot spot for the powe...
