机械化数学——吴消元法在电力系统中的应用初探

Mechanized Mathematics-Wu Elimination Method Applied in Power System

本文在简要介绍了机械化数学——吴消元法基本内容的基础上，通过四个具体的算例——计及磁路饱和的同步发电机稳态运行的内部变量、同步发电机ｄ轴等值电路参数求取、计及饱和的凸极同步发电机同步自励磁现象研究和潮流多解计算，来探索吴消元法在电力系统中的应用。由于电力系统计算中的非线性，传统上多依靠数值方法，吴消元法所具有的强解析性，显示了其在电力系统中应用的潜力和优越性。

The paper introduces mechanized mathematics-Wu Elimination Method in brief.Four specific example,Generator steady state operation considering magnetic saturation,the daxis equivalent circuit parameters in synchronous generator,self excitation phenomena with salient pole synchronous generator and multiple solutions of load flow,are illustrated to explore the application potential of Wu method in power system analysis.On tradition these problems were solved numerically.The analytical nature of Wu Elimination Method manifests its superiority
