摘　　要：介绍提升礼河四级复建电站调速系统空载工况下的稳定性能的过程。通过观察分析调速系统在空载工况下频率波形的变化规律,综合考虑PID参数中比例参数、积分参数、微分参数的作用原理以及参数的局限性,合理选用匹配的PID参数,最终通过优化调速系统空载工况下的控制PID参数,实现调速系统空载工况下的稳定性能满足规程要求的目的。This paper describes the process of improving the stability of speed control system of Yilihe Fourth Cascade ReconstructionHydropower Station under no-load condition.By observing and analyzing the variation rule of frequency waveform of speed control system under no-load condition,and taking into account the function principle of proportional parameter,integral parameter,differential parameter and limitation of parameters in PID parameters,the matched PID parameters are reasonably selected.Finally,by optimizing the control PID parameters under no-load condition of the speed control system,the stability of the speed control system under noload condition can meet the requirements of regulations.
