超高压直流输电系统故障诊断新方法

Research on a New Method of HVDC System Fault Diagnosis Based on Auto Disturbance Rejection Controller

超高压直流输电是一项新的输电技术,而故障诊断是该技术的核心。目前国内对超高压直流输电系统故障诊断的研究较少,针对这一现状,文章在分析超高压直流输电系统故障类型的基础上,提出了一种故障诊断的新方法。

HVDC is a new type of power transmission technology developing rapidly in recent years.Fault diagnosis is the core technology of HVDC.Considering the existing state that researches on HVDC system fault diagnosis of home and abroad are relatively rare,the paper first studied the types and features of various HVDC system faults.Base on this,Auto Disturbance Rejection Controller（ADRC） are used in system fault diagnosis and we put forward a new method of fault diagnosis.
