摘要:牛頓-拉夫遜算法(NR法)是目前廣泛采用的電力系統潮流計算的計算機算法,P-Q分解法(PQ法)派生于以極坐標表示時的牛頓-拉夫遜算法。本文采用VC++6.0開發工具,使用C++語言實現了NR算法與PQ算法,并對實驗結果進行了比較,分析了兩種算法在實際應用中的差異,供使用時做出選擇。

Abstract: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.
