Power supply system power equipment life cycle management method and system

Abstract

The invention provides a life cycle management method and system for power equipment of a power supply system. The method comprises the following steps: acquiring power equipment information in the power system; analyzing the collected power equipment information, and obtaining the power equipment information with the life cycle deadline contained in the power equipment; predicting the life cycleof the power equipment with the life cycle period according to the actual working environment; determining the lifetime loss probability of the detection time point according to the predicted life cycle of the actual working environment; establishing a maintenance planning model based on reliability analysis through the ideal life cycle, the lifetime loss probability and the detection time point;and performing calculation processing according to the maintenance planning model, and obtaining the optimal maintenance time of the power equipment with the life cycle deadline. Therefore, the maintenance is purposeful, the informatization level is high, the situation that the service life expires is properly handled, and the operation risk of power equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of management of power supply equipment in a power system, in particular to a method and system for lifecycle management of power equipment in a power supply system. Background technique [0002] The power equipment of the power supply system is generally supervised and managed in the way of regular inspection, and the scope of maintenance is usually carried out in accordance with the sampling ratio required by relevant standards. There are many problems in this supervision and management mode, such as random inspection with blindness and low level of informationization. It is impossible to conduct continuous comparative analysis and accurate evaluation; there are obvious differences in the cumulative inspection frequency of various electrical equipment, over-inspection, over-repair and under-inspection, and missed inspections are common. The failure of equipment will virtually increase the operation risk of...
