系统辨识思想在串联晶闸管换流阀故障诊断中的应用
The Application of the Concept of System Identification to Failure Diagnosis of Series Thyristor Valve
-
摘要: 高压直流输电用晶闸管换流器的阀臂由多个晶闸管串联构成,长期以来这种换流阀的故 障诊断问题一直没有得到很好地解决.本文应用系统辨识的思想提出了一种全新的办法,较 好地解决了这一难题,并对文中提出的故障诊断方法,讨论了诊断系统的实现问题.Abstract: The application of the concept of system identification to fault detection of thyristor valve in high voltage direct current power transimission is discussed. The simulations of short and broktn circuit failures have been tes ed and the practical feasibility has been studied.
