摘　　要：电力系统潮流计算中最常见的3种算法分别为牛顿-拉夫逊算法、高斯-赛德尔算法以及快速解耦法。针对多节点电力系统潮流计算方法的选择问题,首先介绍了牛顿-拉夫逊算法、高斯-赛德尔算法以及快速解耦法3种潮流计算的方法,随后应用MATLAB进行仿真,并对仿真结果的一致性和快速性加以对比与分析。由结果对比可知,对于6节点线路,牛顿-拉夫逊算法、高斯-赛德尔算法以及快速解耦法的一致性成立,高斯-赛德尔算法的快速性最优,最后对3种算法的优缺点以及改进方法进行了简单介绍。The three most common algorithms in power flow calculation are Newton-Rafson algorithm,Gauss-Seidel algorithm and fast decoupling method.In this paper,Newton-Raphson algorithm,Gauss Seidel algorithm and fast decoupling method are firstly introduced,and then MATLAB is used to simulate,and the consistency and rapidity of the simulation results are compared and analyzed.By comparing the results,it can be seen that for the 6-node line,the consistency of Newton-Lafson algorithm,Gauss-Seidel algorithm and fast decoupling method is valid,and the rapidness of Gauss-Seidel algorithm is the best.Finally,the advantages and disadvantages of the three algorithms and the improvement methods are briefly introduced.
