【摘要】：针对多通道受电断面解列装置动作存在解列时刻偏晚及不同通道解列不同时性的问题,结合南方电网多通道断面振荡解列装置动作行为,采用时域仿真分析方法提出缩短解列装置判别周期和建设广域失步解列系统联切剩余通道的改进措施,有利于解列后送受端电网快速恢复稳定。分析得出电磁环网解环、低压减载措施、高频切机措施等因素均会引起多通道受电断面振荡中心迁移,并研究振荡解列动作时间对送受端电网的其他第三道防线措施量的影响。
[Abstract]:In order to solve the problems of late time and different time of demultiplexing, the action of multi-channel Oscillation defibrillator in Southern Power Grid is analyzed. The time domain simulation analysis method is used to shorten the judging period of the defibrillator and to build a wide area out-of-step decoupling system, which is beneficial to the rapid restoration of the stability of the power network at the end of de-listing and evacuation. It is concluded that the factors such as electromagnetic loop decoupling, low voltage load reduction, high frequency cutting and so on will result in the shift of the oscillation center of the multi-channel electric section, and the effect of the action time of the oscillation unwinding on the other third line of defense measures in the receiving end network is studied.
