Study of predicting breakdown voltage of stator insulation in generator based on BP neural network

摘要

Subjected to a combination of electrical,ther-mal and mechanical stresses duringthelongter mop-eration,both electrical properties and mechanicalstrength of the stator insulation of generator will bedeteriorated continually—that is,aging—till the in-sulation is finally broken down.The accident notonly endangers generator itself,but also causes largeeconomic loss due to sudden blackout.Nowadays,the aging condition assess ment of stator insulationingenerator is ani mportant research subject in electri-cal insu...
