摘要
针对高压直流输电系统故障闭锁导致功率输送的突发性中断,引发大规模的潮流转移,从而造成电网运行的不稳定问题,介绍并分析了一起由多维因素综合导致的高压直流输电系统典型闭锁事件。阐述了该事件的发展过程,分析了该事件处理过程中存在的疑难点,并提出了避免类似故障再次发生的建议。
the blocking fault in HVDC transmission system can lead to sudden interruption andmassive transfer of power transmission, which causes the instability of power grid operation. Onetypical blocking fault in HVDC transmission system caused by multi-factor is introduced in this pa-per, the developing process of the event is expounded, the difficult points existing in the event pro-cessing are analyzed, some suggestions are proposed to avoid similar failures.
