适用于频率安全稳定的低频切泵及减载协调优化方法

摘要

Based on time domain simulation analysis method, through observing and comparing the trajectories, under frequency load shedding （UFLS） is compared with under frequency pump shedding （UFPS） in their performance and effectiveness. Then UFLS and UFPS scheme setting methods are proposed. The coordination and optimization method between UFLS and UFPS is firstly proposed. The proposed method is verified through case studies, and the results show that this method is effective and feasible.%基于轨迹的时域动态仿真分析方法,在比较低频切泵与低频减载性能及控制效果等方面差异的基础上,总结了电网低频切泵和低频减载的整定方法,提出了低频切泵与低频减载两者之间的协调优化方法。通过仿真算例对该方法进行了验证,结果表明该方法可行、有效。
