摘要
以具有上下游调压井的典型复杂水力系统为对象,建立了用于电力系统暂态稳定分析的水轮机和输水系统不同形式的数学模型。利用电力系统分析综合程序提供的用户自定义模型接口功能,在多机系统暂态稳定计算中分别计入水力系统不同模型,分析了水轮机和输水系统不同模型对暂态稳定计算结果的影响。
Based on typical complex hydraulic system with upper and lower surge tanks, different models of hydro-turbine and conduit system used in power system transient stability analysis are presented. Using the user-defined model function of PSASP, transient stability computation is carried out and different models of hydraulic system are taken into consideration. The effect of different hydro-turbine and conduit system models on transient stability computation is compared and analyzed.
