| 摘 要： | 由于潮流雅可比矩阵在临界点处奇异,临界点附近病态,连续潮流计算在临界点附近的收敛性无法得到有效保证。为克服该缺点,对局部参数连续法作了一定的改进,改进后的算法能够有效保证连续潮流计算在临界点及其附近的收敛性。与CPFLOW程序的比较结果证明了该方法的正确性和有效性。

| Abstract: | The convergence of conventional continuation power flow calculation can't be guaranteed near collapse point because of the singularity of Jacobian matrix at collapse point.To overcome it,locally parameterized continuation power flow method is used for improvement.The improved method can effectively guarantee the convergence of continuation power flow calculation even near collapse point.Comparison with the CPFLOW program on IEEE-118 bus test system confirms its correctness and effectiveness. |

| Keywords: | continuation power flow point of collapse Jacobian matrix singularity |
