| 摘 要： | 连续潮流法是求取静态电压稳定极限的一种有效的方法。根据预测和校正过程的不同，连续潮流法具有不同的形式。提出了改进的连续潮流法，使用PQ分解法求解潮流，预测过程使用Lagrange二次插值技术，校正过程采用局部参数法求解修正方程。与传统的使用基于极坐标形式的牛顿一拉夫逊法的连续潮流法相比，所提的改进连续潮流法计算速度快、占用内存少、准确度高。

| Abstract: | Continuation power flow algorithms are effective for obtaining the limit of static voltage stability and they have different forms according to different predictor-corrector processes. This paper presents an improved continuation power flow algorithm, whose characteristics are as following: PQ decoupled power flow algorithm is used; Lagrange quadric interpolation is used in the process of predictor and locally parameterized method is used in the corrector. Compared with conventional continuation power flow based on New-Raphson method, the improved algorithm has advantage in terms of computation speed, less memory requirement and accuracy. |
