摘要
以怒江电网为背景,在220 k V剑兰Ⅰ回线停电检修期间,220 k V福剑线故障跳闸怒江福贡、贡山和兰坪电网独立网运行期间高频切机和低频减载的动作情况进行仿真,模拟独立网运行期间的频率变化曲线,提出怒江电网高、低周措施的优化方案,对于后续保证怒江电网的安全稳定运行有重要意义。
The in the network of the Nu River as the background, during the 220 kV Gladiolus I loop maintenance outage, 220 kV Fu sword line fault tripping Nujiang Fugong, Gongshan and Lanping grid independent network during the running of the high-frequency cutting machine and low frequency load shedding the action simulation simulation of frequency variation curve of net independence during the operation, the Nujiang grid high - and low cycle measures optimization scheme, for the follow-up to ensure the safe and stable operation of Nujiang grid has important signiifcance.
