中文摘要:

在传统连续潮流的基础上,一种改进参数化方法的连续潮流算法在本文提出,使用该算法可以快速、准确地进行电力系统静态电压稳定分析。该算法在潮流计算过程中使用PQ分解法,预测过程采用拉格朗日二次插值技术预测下一步的潮流解的初值,校正过程使用基于几何相似原理的改进参数化方法校正预测值,步长控制采用变步长控制方法。和传统连续潮流法相比该算法具有计算时间短、内存占用少、计算准确度高等特点。算例分析表明该算法是可行的、快速的、准确的。

英文摘要:

In this paper a future improvement was made based on continuous flow method. The algorithm is faster and more accurate when used to analysis the static voltage stability of power systems. PQ decoupled power flow algorithm is used, Lagrange quadric interpolation is used to predict the next initial value in the process of predictor and an improved parameterized method based on the principles of geometric similarity is used in the corrector. Compared with conventional continuation power flow, the improved algorithm has advantages in terms of computation speed, less memory requirement and accuracy. Sample studies show that the algorithm has the advantages of feasibility, high-speed and high accuracy.
