中文摘要	在大量数值经验的基础上,从数值现象上区分了连续潮流计算失败的2种现象:临界点失败和非临界点失败。继而从理论上分析了出现这2种现象的原因:造成临界点失败的原因是对于某些具有强烈局部性质的电压失稳情形,采用全局性参数化方法无法克服临界点雅可比矩阵奇异;造成非临界点失败的原因是参数化使得原系统中的非奇异点变为系统扩展雅可比矩阵的奇异点。该文提出采用局部参数化方法取代弧长或拟弧长等全局性参数化方法来避免临界点失败,并采用参数受迫变换策略来克服非临界点失败。对一个实际系统的数值计算表明,该文所提的提高连续潮流计算鲁棒性的策略是有效的。; Based on a large amount of practical experience, the computation failures of Continuation Power Flow can be phenomenally divided into two kinds: the turning point failure and the non-turning point failure. The reasons behind the failures are analyzed theoretically. The reason of the turning point failure is that the global parameterization can not overcome the singularity of Jacobian matrix for some voltage instability cases with strong local characteristic. The reason of the non-turning point failure is that some nonsingular points of original system are translated to the singular points of the extended Jacobian matrix by the parameterization. Using the local parameterization instead of the global parameterization such as arclength or pseudo arclength parameterization to avoid the turning point failure is advocated in this paper. A forced parameter switching strategy is proposed to overcome the non-turning point failures. Case studies with a practical power system indicate that the proposed strategy is very efficient.; 国家重点基础研究发展规划项目(973项目)(2004CB217904)~~
