摘　　要：通过PSASP程序仿真分析,吐鲁番地区电网与新疆主网解列后,系统出现有功功率不同缺额时,不同的低频减载方案动作后,对电网频率和电压恢复进行了对标分析。结果表明,方案1低频动作对电网频率和电压瞬间影响较小,但方案2在频率和电压恢复上好于方案1。该结论可为供电部门对低频定值整定提供一定的参考。Through the simulation analysis with PSASP, when there are different active power vacancy after Turpan regional power grid is separated from the main grid of Xinjiang, the recovery of power grid frequency and voltage are analyzed for differ- ent low - frequency load shedding schemes. The results show that the low - frequency action in the first scheme has smaller in- stantaneous influence on the frequency and voltage of power grid, and it has a better recovery of frequency and voltage in the second scheme. The conclusion could provide a reference for low -frequency fixed value setting.
