摘要
统一潮流控制器(UPFC)包含有串联侧换流器和并联侧换流器两部分,在近端线路发生故障时,UPFC串、并联的换流器均会受故障影响,对于线路的瞬时性故障,需要UPFC能承受故障冲击,并且在线路故障清除后继续运行。人工短路试验可以考验UPFC的故障穿越能力,文中通过对南京UPFC示范工程的人工接地短路试验的结果进行分析,验证示范工程主设备参数的设计,和故障处理策略的合理性。
Unified power flow controller (UPFC) consists of two parts, namely series and parallel converters. When faults happen on the line near the two parts, converters respectively at the series side and parallel side will be both affected. The UPFC must have the ability against the line instantaneous fault, and the ability to continue running after the fault is cleared. Artificial short circuit test can test the fault ride-through capability of UPFC. The parameter design of main equipment and strategy against faults of Nanjing UPFC pilot project are proved reasonable by the analysis of the artificial grounding test results.
