基于模糊综合评价的水轮发电机组局部放电状态评估
State assessment on partial discharge in hydro-generator unit based on fuzzy comprehensive evaluation
摘要
Abstract
Partial discharge (PD) can effectively reflect the insulation condition of hydro-generator unit,thus the state assessment of PD fault being significant to master the degree of insulation deterioration of hydro-generator unit.A state assessment model of PD based on the fuzzy comprehensive evaluation is established in this paper.Firstly the PD faults of the unit are divided into three kinds of state levels according to the actual operation of hydro-generator unit and discharge energy.Then with five statistical parameters of PRPD as the evaluation index,the state assessment model of PD fault of hydro-generator unit based on fuzzy comprehensive evaluation is established.Finally,the severity of the PD fault of the unit is evaluated according to the degree of membership.Example analysis result shows that the method can be used to evaluate the insulation condition of the unit by judging the state level of the PD fault of hydro-generator unit accurately and effectively,and that it has certain engineering practical value.关键词
