摘要
提出适用于大型电力系统电压稳定分析的改进连续潮流法，该算法能很好地克服大型电力系统的雅可比矩阵在临界点附近奇异的现象，从而使寻找电压临界点的工作变得迅速。准确，并且具有较好的收敛性；阐述发电机无功越限对静态电压稳定性的影响；试例验证取得了满意的结果。
This paper proposes a fast and accurate algorithm for determination of static voltage stability limit(VSL)on large power systems,namely the Modified Continuous Load Flow Algorithm,This algorithm can effectively avoid the singu- larity of Jacobian matrix near VSL and overcome the problem of divergence.Applying direction cosine to compute the step size for solving VSL is in favor of fast and accurate convergence property.The effect of generators reactive power con- straints of the static voltage stability is analyzed in this paper.The calculations have shown that this algorithm is satisfacto- ry being used for a large power system with about 700 buses
