Embodiment 1

[0055] This embodiment provides a method for risk assessment of power metering equipment based on RPN, please refer to figure 1 , the method includes:

[0056] First perform step S1: analyze the fault type and fault impact of the power metering equipment based on the RPN method, and determine the evaluation index of the power metering device, where the evaluation index includes the probability of failure, personnel environment factors, system function factors, maintenance time factors and Maintenance cost factor.

[0057] Specifically, RPN (riskprioritynumber) refers to the product of the frequency, severity and detection level of the event, which is called the risk coefficient or risk sequence number. The larger the value, the more serious the potential problem, and it is used to measure possible process defects. , in order to take possible preventive measures to reduce critical process variations and make the process more reliable. In the present invention, the method base...

Embodiment 2

[0105] This embodiment provides a risk assessment device for power metering equipment based on RPN, please refer to image 3 , the device consists of:

[0106] The evaluation index determination module 301 is used to analyze the fault type and fault impact of the power metering equipment based on the RPN method, and determine the evaluation index of the power metering device, wherein the evaluation index includes the failure probability, personnel environment factors, system function factors, Maintenance time factor and maintenance cost factor;

[0107] A level determining module 302, configured to determine the level of each evaluation index by adopting hierarchical cause analysis according to the level of the power metering equipment;

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

[0109] A model construction module 304, configured to construct a failure mode risk eva...

Abstract

The invention provides a method and a device for risk evaluation of electric power metering equipment based on RPN. The method analyzes the fault type and parameter, the fault influence and the faultreason of the on-site metering equipment, mainly involves the influence degree of the personnel environment, the system function, the maintenance time and the maintenance cost, then constructs the evaluation factor weight based on the AHP, finally carries on the electric power metering equipment risk evaluation. At the same time, the method of the invention can provide guidance for the maintenance of the electric power metering equipment, can solves the problem that the evaluation result is inaccurate because of the variety of electric power metering equipment, the huge quantity and the complex operation condition, and can improve the accuracy of the evaluation results and achieve the technical effect of risk classification.

Description

technical field [0001] The invention relates to the technical field of data mining in computer science, in particular to an RPN-based risk assessment method and device for power metering equipment. Background technique [0002] Since 2010, the State Grid Corporation of China has started the construction of an electricity consumption information collection system, and has accumulated a large amount of data from metering equipment. However, there are many kinds of metering equipment, a large number, and complex operating conditions. The abnormal discovery and analysis are manually derived and analyzed by the operation and maintenance personnel, which completely depends on the experience of the operation and maintenance personnel. Therefore, the use of multiple database data and data mining technology has theoretical and practical significance for the early warning and risk prediction of equipment in operation. [0003] At present, the risk of equipment operation has always be...
