摘要
基于数字仿真实验以及小干扰稳定的理论分析了发电机组对电力系统功率振荡的作用,通过对水轮机及其调速系统的小干扰分析和对某两机系统的PSASP仿真实验,得出了结论:电力系统中水电机调速系统软反馈,对电力系统的动态稳定性有较大影响。
The effect of hydro-turbine governor system on the power oscillation of power system is studied based on PSASP numerical simulation and small-signal interference analysis. The results show that the soft feedback output values of hydro- turbine governor system have greater impact on power system dynamic stability.
