| 摘 要： | 由于水力系统的水锤效应和强非线性特性，水轮发电机组采用常规控制难以取得令人满意的效果。介绍了水轮发电机组调速器侧模糊电力系统稳定器FGPSS(Fuzzy Governor Power System Stabilizer)的设计原理。应用Simulink仿真软件构建了以水力系统弹性水击模型和同步发电机非线性模型为基础的仿真模型，并对采用PID，PID 常规GPSS和PID FGPSS三种控制方式的控制效果进行了仿真对比研究。结果表明，FGPSS对于改善电力系统的稳定性具有良好的作用，而且具有较强的鲁棒性。

| Abstract: | The conventional hydro-generator governor can not satisfactorily control hydro-generator stability because of the hydraulic system's water-hammer effect and intense nonlinear characteristic.The design principle of FGPSS(Fuzzy Governor Power System Stabilizer)for hydro-generator unit is described.The simulation model is established with Simulink based on the elastic water hammer mode of hydraulic system and nonlinear model of synchronous generator.The control results are compared among PID+FGPSS,PID and PID+Conventional GPSS,which indicate that FGPSS can improve hydroelectric system stability and has strong robustness. |
