摘要
给出水力系统大波动与小波动模型 ,推导出适合于电力系统分析的水力系统大波动模型差分化方程。在此基础上 ,仿真并分析了负荷对水机的影响以及不同水力系统模型对电力系统稳定的影响 ,认为应根据研究的不同侧重点采用不同的水击模型 。
L arge- signal and sm all- signal m odels of hydraulic system are presented,and differential equations of large- signal model are deduced. The effects of power load on hydraulic system and mechanical system and the effects of differenthydraulic system s on the stability of power system are also analyzed and com pared.Finally,it is pointed out that different hydro- striking models should be adopted for different intention of research.
