Overvoltage Suppression Effect of AC UHV Electronic Controllable Arrester
交流特高压电力电子式可控避雷器(以下简称电子式可控避雷器)可以实现对多种高幅值暂态过电压的深度抑制,是目前特高压系统深度抑制操作过电压的有效手段,其可控比、动作电压等参数是决定其操作过电压抑制程度的重要因素.本研究建立了典型特高压交流GIS电站仿真模型,系统研究了电子式可控避雷器配置参数对操作暂态冲击下的保护特性的影响,获得了不同参数配置、线路长度下对过电压的抑制效果,为工程应用中电子式可控避雷器参数的优化选择配置提供了参考依据.
AC UHV power electronic controllable arrester(referred to as electronic controllable lightning arrester)can realize the deep suppression of a variety of high amplitude transient overvoltage,which is an effective means of deep suppression of switching overvoltage in UHV system.The controllable ratio and operating voltage of electronic controllable arrester are important factors to determine the degree of over-voltage suppression.A typical UHV AC GIS station simulation model is established to systematically study the influence of electronic controllable arrester configuration parameters on the protection characteristics under switching impulse.The suppression effect of overvoltage under different parameter configuration and line length is obtained,which provides a reference for the selection and configuration of the parame-ters of the electronic controllable lightning arrester in engineering applications.
