Application of Fuzzy Fheory in Communication Network Evaluation of Intelligent Substation
Aiming at the problems of difficult and complex communication network state evaluation of intelligent substation,based on the architecture of intelligent substation,a fuzzy theory is proposed for the comprehensive evaluation of communication network state of intelligent substation.The elements are transformed into membership degree by membership function,combined with analytic hierarchy process and Spearman correlation coefficient method to determine the weight,the comprehensive evalua-tion results are obtained according to the membership degree and weight.Through the comparative analysis of different cases,the superiority of this method is verified.The results show that this method can not only reflect the state of the whole communication network,but also further reflect the load state and message transmission effect,which provides a certain basis for the maintenance of system state.
