摘　　要：电力系统的稳定性受发电机励磁控制系统的影响较大,在对电力系统建模进行稳定计算时,一旦励磁控制模型和参数改变,稳定计算结果就会千差万别。笔者介绍了基于在线频率响应特性分析的数字仿真和现场试验相结合的电力系统稳定器(PSS)参数优化方案:利用提供的励磁控制系统与发电机参数建立励磁系统的仿真模型。通过仿真与现场试验相结合的频率响应特性分析法,验证PSS的性能。通过仿真和性能实测,励磁系统参数经过优化设置后,其对电网频率为0.1~2.0 Hz的低频振荡有很好的抑制作用。The stability of power system is greatly affected by the excitation control system of generator. In the stabilitycalculation on modeling of power system the stability calculation results will be quite different when the excitation controlmodel and parameters are changed. This paper introduces parameter optimization scheme of power system stabilizer PSS based on digital simulation and field test of on - line frequency response characteristic analysis. Meanwhile the providedexcitation control system and generator parameters are used to build simulation model of excitation system and verify the PSSperformance by the frequency response characteristic analysis method. The excitation system is optimized through thesimulation and performance measurement having a good suppression effect on low-frequency oscillation of 0.1-2.0Hz in thepower grid system.
