Application of Variable Weight Coefficient Method in State Evaluation of AC Contactor
AC contactor state evaluation is a challenging problem.This paper proposes an AC contactor state assessment method based on variable weight coefficient.Firstly,the characteristic indicators that have a great influence on the state of the AC contactor are selected,and the state evaluation index system is established.Secondly,using the subjective and objective combination weighting method combined with the analytic hierarchy process and the grey relational analysis method,the constant weight coefficient is obtained,and the variable weight coefficient method with the equalization function is introduced to obtain the variable weight coefficient of each characteristic parameter.Finally,the fuzzy comprehensive evaluation method is used to evaluate the running state of the AC contactor.The experimental results show that the state evaluation method proposed in this paper can accurately reflect the real state of the AC contactor operation and effectively improve the reliability of the power system.
