摘　　要：针对现有连续潮流法在求取电力系统的PV曲线时存在的问题,提出了一种基于快速分解法的改进潮流算法.负荷节点从基本工况开始增加,预测过程采用光滑插值技术,校正过程采用局部参数化求解修正方程获取完整的PV曲线.以IEEE39节点系统为例进行仿真,仿真结果表明该算法快速、准确、精度高,具有实用价值.In view of problems existed in calculating PV curves of the power system by continuation power flow （CPF） method, an improved power flow algorithm was proposed on the basis of fast decoupled method. The load node began to increase from the basic working conditions, the smooth interpolation technique was used in the prediction process, and the local parameterization was used in the correction process to solve the correction equation for obtaining a complete PV curve. Taking the IEEE39 system as an example, simulation results indicated that the algorithm was fast, accurate and of high precision as well as practical.
