继电保护故障信息和录波波形的识别方法

Identification Method of Relay Protection Fault Information and Recorded Waveform

电网故障会影响电网正常运行,及时有效定位电网的故障点,能够使电网快速恢复正常运行。介绍电网故障状态的电气特征,论述保护装置动作信息和动作波形的识别方法。以RCS-931型线路保护装置的动作信息和动作波形为例,分析故障信息识别方法。通过设置参考线的方式,有效解读了故障的波形信息,对定位故障点有参考借鉴意义。

Power grid fault will affect the normal operation of power grid.Timely and effective fault location of power grid can make the power grid quickly return to normal operation.The electrical characteristics of power grid fault state are introduced,and the identification method of protection device action information and action waveform are discussed.Taking the action information and action waveform of RCS-931 line protection device as an example,the identification method of fault information is analyzed.By setting reference line,the waveform information of fault is effectively interpreted,which is of reference significance for locating fault points.
