摘要
舟山多端柔性直流输电换流站内直流断路器作为针对直流断路器用电力电子电容器的首台首套设备,目前尚无评价办法。对其工作原理、组成结构和技术特点等进行了介绍,对投运近3年的2台断路器主支路的直流支撑及转移支路吸收电容器进行了应力分析和抽检试验,给出运行评价流程,为后续其他直流电网工程提供经验借鉴。
There is no evaluation method for a DC circuit breaker that uniquely adopts power electronic capacitor in Zhoushan VSC-HVDC project.The principle,components and technical characteristics are introduced.Stress analysis and sampling test on DC support and transfer branch absorption capacitor of two circuit breakers that have operated three years are conducted,and the operation evaluation process is given,which provides experience for other DC power grid projects.
