摘要
介绍了天生桥换流站交流滤波器高压电容器的构成,基于高压电容器不平衡保护原理总结了不平衡保护的优缺点,并分析了外部环境参数对电容器电容值的影响。以C型交流滤波器不平衡保护跳闸原因为例,提出了相应的整改措施,供借鉴。
This paper introduces the structure of high voltage capacitor of AC filter in Tianshengqiao converter station. The merit and demerit of unbalance protection is summarized by the principle of unbalance protection for high-volt- age capacitor. The effect of external environment parameters on the capacitance is analyzed. Taking the cause of unbalance protection tripping operation for C type AC filter for an example,it brings forward the solution method and provides reference for similar engineering project.
