摘　　要：分析了交流滤波器投切对换流站交流系统电压的影响,并论述了可控换相换流阀(CLCC)技术原理,通过对比分析可控换相换流阀在上海A换流站的实践应用,论证了当交流滤波器投切引起三相交流电压畸变时,可控换相换流阀可成功抵御换相失败,为其他工程采用可控换相换流阀提供参考。This paper analyzes the influence of AC filter switching on AC system voltage of converter stations,and discusses the technical principles of Controllable Line Commutated Converter(CLCC),and then by comparing and analyzing the practical application of CLCC in Converter Station A of Shanghai,demonstrates that CLCC can successfully withstand commutation failure when the switching of AC filters causes three-phase AC voltage distortion.This provides a reference for the application of CLCC technology in other projects.
