摘要
为明确水力系统模型在电力系统低频振荡中的作用,运用全部特征值法,分析了水力系统的弹性水击、刚性水击和简化模型对水火电联合的三机系统小干扰稳定性的影响,得出了对含有水电站的电力系统进行低频振荡分析时,应该采用更为精确的水力系统弹性水击模型的结论。
In order to make clear the effect of hydraulic system on power system dynamic stability, the effect of different hydraulic system models on low frequency oscillation are compared and discussed in three machines hydro-thermal system, using eigen-analysis. The results indicate elastic water-hammer is optimum model in studying low frequency oscillation of power system relating to hydroelectric station.
