摘要
针对地区电网与主电网解列后产生的高频问题,进行了地区电网频率动态过程的仿真研究,对该地区的高频切机方案进行了分析。计算结果表明:不同的切机方式对地区电网的频率恢复影响很大,该结果可为此类事故的处理提供依据。
High frequency problem occurs when the local power network is disconnected from the main power network. Based on this,the dynamic process of frequency in the local power network is simulated,and the high-frequency cutting machine schemes are analyzed.It is found that the cutting approach is of great significance to the frequency recovery of local power network,that provides a reliable basis for dealing with such incidents.
