Research on the Model of CVT Operation Performance Based on the PHM System

This paper researches on the operation performance of capacitive voltage transformer(CVT) in the operation of the network. Firstly, the structural principle and application technology of PHM system are expounded. Then the fuzzy comprehensive evaluation model is introduced. Combined with the CVT operating characteristic parameters monitored by the CVT online monitoring device, the CVT operating performance model based on PHM system is proposed. Finally, the CVT of 220kV Shuping Station in Zigong City is taken as an example for analysis. Through the analysis of the field experimental data, the correctness and practical engineering feasibility of the model are proved.
