摘要
以小浪底水电站为对象建立了用于电力系统暂态稳定分析的不同形式的水力系统数学模型,包括不均匀单管刚性水击模型和弹性水击模型以及计及机组间水力耦合的两元输水系统弹性水击模型、水轮机的线性化模型和非线性模型。利用电力系统分析综合程序提供的用户自定义模型功能对河南电网进行了暂态过程仿真,分析了不同水力系统模型以及水力耦合对电力系统暂态稳定性的影响。
Taking the Xiaolangdi hydropower station as research object, different forms of mathematical models of hydraulic systems for power system transient stability analysis, including uneven single pipe rigid water-hammer model, elastic water-hammer model, elastic water-hammer model of two-unit conduit system which takes the hydraulic coupling between the units into account, and the linearized and nonlinear models of hydroturbine, are built up. Using the user's define function provided by power system analysis software package (PSASP) the transient simulation of Henan power system is carried out, and the influences of different hydraulic system models and hydraulic coupling on the power system transient stability are analyzed.
