摘要
在电网系统运行中,110 kV内桥接线变电站进线单相断线事故通常较少发生,而由于该类事故的特殊性,在其发生后,如何进行准确分析和判定,进而及时采取有效解决措施,是促进电网稳定运行的一个重要课题。文中结合某地区110kV变电站实例,研究了在单相断线事故出现后引起的现象与特征,然后提出了相应的解决措施,对调度准确、迅速判定故障类型具有一定的参考价值。
During operation of power system, input single-phase disconnection faults of 110 kV inner bridge connection substa-tion happen less often normally. Due to particularity of such faults, it is an important issue to promote stable operation of power grid to analyze and diagnose them accurately after occurrence, and take effective measures in time. With example of 110 kV substation in a certain area, the article researches phenomena and characteristics caused by single-phase disconnection fault, and puts forward corresponding solutions, which are of some certain reference value for accurate dispatching, fast determination of fault types.
