摘要
阐述了用改进的连续潮流法求取电力系统的ＰＶ曲线。该方法通过增加一维潮流方程，消除了功率极限点附近的雅可比矩阵奇异的现象，获得精确的电压稳定极限和整支ＰＶ曲线。算法中考虑了系统的多项限制，并采用了预估校正技术，运算更加快捷精确，同时利用系统左特征矢量的性质获得系统临近崩溃时的最优控制方向。
In this paper, an improved continuation method is presented to trace the PV curve of power systems. By using an augment equation, this algorithm can pass the 'nose' point and get the whole PV curve without encountering the numerical difficulty of ill conditioning. The predictor corrector technique makes its computation fast. It is also presented a method of getting an optimum control direction when the system is near voltage collapse by using the characteristics of left eigenvector.
