摘要
换相失败是传统直流输电系统最为常见的问题之一,为了能从根本上消除换相失败所带来的影响,根据高压直流断路器的工程经验,一种具备可控关断能力的可控换相换流器(CLCC)在近年已经进行了工程应用,为验证CLCC设计的合理性和正确性,准确反映其中各个元器件的电气应力,结合CLCC换流阀的运行特点以及传统晶闸管换流阀和混合式直流断路器的运行试验,对CLCC换流阀的运行试验项目进行了研究.本文介绍了CLCC换流阀的拓扑结构和工作原理,运行试验方法,并进行了仿真验证,最后,成功地用CLCC换流阀样机进行了运行试验,验证了CLCC换流阀的可靠性.
Abstract
Commutation failure is one of the most traditional HVDC transmission system.In order to fundamentally eli-minate the impact of commutation failure,based on engineering experience of the DC circuit breaker,a controllable line commutated converter(CLCC)with controllable switching off capability has been applied in recent years.In order to ve-rify the rationality and correctness of the design of CLCC,accurately reflect the electrical stress of each component,the operation test item of CLCC converter valve is studied combined with the operation characteristics of CLCC conver-ter valve and the operation test of traditional thyristor converter valve and hybrid DC circuit breaker.The topological structure and working principle of CLCC converter valve,the operation test method,and the simulation verification are introduced.Finally,the CLCC converter valve prototype successfully verifies the reliability of CLCC converter valve.
