摘要(Abstract)：

实际异步联网系统中多次发生长时间、超低频振荡事件。研究发现,调速器参数设置不合理是导致振荡发生的重要原因。首先采用简化型PID调速器进行验证,研究了永态差值系数bp对于电力系统稳定性的影响。接着基于单机单负荷的模型,采用遗传–粒子群(GA-PSO)算法对电力系统中调速器的PID参数进行优化处理,在MATLAB/Simulink仿真软件中搭建单机单负荷的模型,通过对优化前后发电机转速偏差波形图的分析,说明所提出的优化算法对于PID型调速器的参数优化的效果,对于抑制电力系统中超低频振荡的现象具有实际的意义。最后在PSD-BPA仿真软件中搭建异步4机2区域以及复现云南电网的实际孤岛模型,对发电机中调速器参数进行仿真验证,通过采用优化算法得到的参数来调节PID参数,结果表明优化后的参数对于超低频振荡具有较好的抑制。
