Operation State Evaluation of Distribution Network Based on Attribute Mathematics

Abstract

Distribution network can implement self-healing when real-time operation state can be mastered comprehensively and operation change tendency can be predicted. Firstly the evaluation index system of operation state was constructed from five aspects (safety, reliability, quality, economy and adaptability). Then, distribution network’s operation network evaluation model was established on the basis of attribute mathematics theory, which could transform this problem into calculation problem of operation state’s attribute measure. Analytic hierarchy process was used to determine the weights of indexes. Finally the process for evaluating operation state was given. The simulation results show that this model can get accurate operation state of distribution network.
