摘　　要：西南电网异步运行后带来的频率稳定问题突出,其中对超低频振荡的抑制的研究成果有待在实际电网中近一步实践。本文首先对超低频振荡问题进行了概述,指出了超低频振荡根源在于水电机组原动机控制系统,随后分析了现有振荡抑制措施的局限性并提出了基于调速器附加阻尼控制(GPSS)的超低频振荡抑制方法。基于时频分析的方法对控制参数进行了整定并在Simulink中搭建了单机带负荷水电机组调速系统模型验证了GPSS的抑制效果。最后,搭建了半实物化仿真试验平台并验证了GPSS的超低频振荡抑制效果,为GPSS在实际电网中的应用提供了实践支撑。The frequency stability problem brought about by the asynchronous operation of the Southwest Power Grid is outstanding.The research results of the suppression of ultra-low frequency oscillations need to be further practiced in the actual power grid.This paper firstly summarizes the problem of ultra-low frequency oscillation,and points out that the root of ultra-low frequency oscillation lies in the control system of hydropower unit prime mover.Then the limitations of existing oscillation suppression measures are analyzed and the additional damping control method based on governor(GPSS)is proposed.The ultra-low frequency oscillation suppression method is based on the time-frequency analysis method,and the control parameters are set.The single-machine-loaded hydropower unit speed control system model is built in Simulink to verify the suppression effect of GPSS.Finally,the semi-physical simulation test platform is built and the ultra-low frequency oscillation suppression effect of GPSS is verified,which provides practical support for the application of GPSS in the actual power grid.
