摘要(Abstract)：
在电网大区域联络的背景下,各区域电网的低频振荡问题变得越来越明显。为了保证电网的安全稳定运行,解除低频振荡对联络线传输功率的限制,采用PSS抑制电力系统的低频振荡必不可少。抑制低频振荡的效果主要决定于PSS参数的整定。借用自适应遗传算法对PSS参数整定优化,并以仿真和实际应用验证其正确性,表明取得良好的效果。
In the context of power grid connection in large areas, low-frequency oscillation in regional power grids is becoming more and more obvious. In order to ensure operation safety and stability of power grid and eliminate limit of low-voltage frequency oscillation to transmission power of tie line, power system stabilizer(PSS) is necessary to inhibit the low-frequency oscillation in electric power system. The effect of low-frequency oscillation inhibition mainly depends on the quality of PSS parameter setting. Adaptive genetic algorithm is adopted to optimize PSS parameter setting, and the simulation and practical application are used to verify the correctness of the method, which turns out to be effective.
