摘要
云南电网异步联网后出现了超低频振荡问题,频率稳定问题成为影响电网稳定水平的重要因素,本文介绍了利用无功电压控制抑制频率振荡的方法,并结合云南电网实际仿真,验证了方法的正确性、有效性,为提高云南异步联网后的频率稳定水平提供了新的思路。
After asynchronous networking of Yunnan power grid,the problem of utra-low frequency oscillation has occuured,and the problem of frequency stability has become an important factor affecting the stability level of the power grid,this paper introduces the method of suppressing frequency ocillation by using reactive woltage control,and combined with the actual simulation of Yunnan power grid,verifies the correctness and effectiveness of the method,and provides a new idea for improving the frequency stability level after Yunnan asynchronous networking.
