| 摘 要： | 把增广潮流方程以克服功率极限点处Ｊａｃｏｂｉ阵奇异的扩展方程与矩阵分裂技术相结合，将确定功率极限点的４Ｎ＋１阶扩展方程的修正方程转化为四个系数矩阵完全相同的２Ｎ＋１阶方程，不仅克服了潮流Ｊａｃｏｂｉ矩阵在功率极限点的奇异性，而且可以大幅度地提高功率极限点的计算速度，快速、精确地求出极限点处理的潮流解和相应的负荷增加因子。

| Abstract: | This paper presents a new
algorithm for finding the power limit point in a power system. This algorithm is made by
combining extended load flow equations for overcoming singularity at power limit point
with matrix decomposition technique for reducing order. The matrix decomposition is
achieved by turning modified equations with 4N+1 demensions of nonlineary extended
equations into four 2N+1 demensions algebraic equations with same coefficient matrix. This
new algorithm not only overcomes singularity of load flow equations at the power limit
point but also reduces the demensions of coefficient matrix of modified equations. This
algorithm accelerates calculation largely, and the power limit point can be found out
correctly. |
