Overvoltage Suppression Effect of AC UHV Electronic Controllable Arrester
摘要
Abstract
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.关键词
