The invention provides an active maintenance-oriented
power equipment health state evaluation method, which comprises the following steps of: firstly, acquiring state quantity index data of any
power equipment in a power
system, calculating the membership degree of each state quantity index through a fuzzy distribution membership
degree function, and constructing a
paired comparison matrix. According to the method, the maximum characteristic value and the initial weight of each corresponding index are calculated, consistency
verification is performed on the maximum characteristic value and the initial weight, and meanwhile, an objective correction coefficient is introduced to correct the initial
weight coefficient, so that the influence of subjective factors in determining the initial
weight distribution is eliminated, and the requirements of
system operation on the aspects of safety, reliability, economy and the like can be better considered; an equipment health state research basis is provided for researching an active
maintenance strategy of
power equipment; the power equipment is kept in an excellent health state in the full-life service cycle, and the optimal service performance of the equipment is maintained by using a low-cost and high-efficiency
maintenance strategy, so that the safe, reliable and economical operation of a power
system is ensured.
