基于C++的电力潮流计算牛-拉法与P-Q法的分析比较

Analysis and Compare Newton-Raphson method to P-Q decoupled method Based on C++

牛顿-拉夫逊算法(NR法)是目前广泛采用的电力系统潮流计算的计算机算法,P-Q分解法(PQ法)派生于以极坐标表示时的牛顿-拉夫逊算法。本文采用VC++6.0开发工具,使用C++语言实现了NR算法与PQ算法,并对实验结果进行了比较,分析了两种算法在实际应用中的差异,供使用时做出选择。

The Newton-Raphson method is widely used in power flow computation, the PQ decoupled method is derived from the polar coordinates expression of the Newton-Raphson method. This dissertation using VC＋＋6.0 application and C＋＋ programme language to realize these 2 methods, in order to recover the differentia between them and for a better choice in power flow computation.
