【摘要】 随着越来越多的自动装置应用于电力系统,给故障诊断提供了充足的信息源。本文对WAMS信息、测控信息、保护信息以及录波信息的基本情况及各自特点进行了分析,按信息上送调度中心的时间先后及信息特点,分为扰动识别、故障元件诊断和事故后分析三个层次对系统进行诊断,并给出了基于这四类信息的故障诊断系统的基本框架结构。更多还原

【Abstract】 As more and more automatic devices have been used in power systems,it provides sufficient information sources for fault diagnosis.This paper gives detailed analyses on the arrival time to control center and the characteristics of WAMS information, measurement and control information,relay protection information and fault recorder information.According to the information’s characteristics and the corresponding arrival time,a fault diagnosis method with its basic framework is presented in this paper,which is divided into three levels:disturbance identification,fault element diagnosis and post-fault analysis.更多还原
