摘要
Abstract
In allusion to the power grid equipment in abnormal state,in order to improve maintenance economy,the paper presents a kind of decision-making method for maintenance based on comprehensive cost analysis.This method comprehensively considers maintenance costs including fixed maintenance cost,additional cost of emergency maintenance scheduling,additional cost of equipment state deterioration,and so on for equipment operation,and some failure costs such as asset depreciate cost and operational loss cost.By analyzing time variation characteristic of different costs,it determines the final maintenance time of the equipment according to the minimized total cost of maintenance.Taking maintenance case of 500 kV and 25 MVA transformer in one substation after suffering low temperature over-heating for an analysis example,it compares maintenance cost of this method with costs of emergency maintenance strategy and regular maintenance strategy.The results show that in the premise of obeying the maintenance principle,the total cost of this method is the least which means significant economic advantage.关键词
