摘要:

特高压直流直接接入交流750 kV电网,对投切交流滤波器小组的断路器的耐压能力提出了严苛的要求,因此需要研究断路器的容性恢复电压水平。分析了交流滤波器小组断路器面临的各种交流故障工况,通过PSCAD软件建立了容性恢复电压的仿真计算模型,并以灵绍特高压直流工程为例计算得出了800 kV交流滤波器小组断路器的容性恢复电压最大值。仿真结果表明交流滤波器小组断路器的容性恢复电压由交流系统的短路水平和交流侧绝缘水平的影响决定,而且容性恢复电压超过了现有标准的要求,需研制适应工程需求的新型断路器。

Abstract:

 The circuit breaker for switching AC filter is required the capacity of withstanding high voltage while the UHVDC direct accesses to 750 kV AC grid, So it is necessary to research the capacitive recovery voltage (CRV) of circuit breaker. This paper analyzed various AC fault scenarios of AC filter sub-bank circuit breaker, constructed the simulation calculation model of CRV by PSCAD software, and calculated the maximum value of CRV of 800 kV AC filter sub-bank breaker in the Lingshao UHVDC project. The simulation results show that the CRV of AC filter sub-bank breaker is determined by the short-circuit level of AC system and the AC-side insulator level, and the CRV exceeds the requirement of existing standards, so it is needed to develop new type of circuit breaker to meet the needs of engineering.

Key words: capacitive recovery voltage, AC filter, circuit breaker, UHVDC
