| 摘 要： | 为克服潮流雅可比矩阵在临界点处的奇异,零特征根法一般需对负荷水平λ作适当变换方可保证算法的收敛２性,但这又使雅可比矩阵原有的稀疏性遭到不同程度的破坏,为此提出一种新参数变换方法,并利用算法的设计技术,较好地保持了雅可比矩耻原有的稀疏性。与连续潮流法及非线性规划法的比较结果证明了该方法的正确性和有效性

| Abstract: | To avoid the singularity of Jaccobian
matrix at Point of Collapse, zero eigen value method needs conversion to λ, which destroys the sparsity of
Jaccobian matrix. A novel conversion method to the parameter λ is proposed in this paper, which is designed to keep the
sparsity of Jaccobian matrix. Comparison with continuation power flow calculation and
nonlinear programming method proves its correctness and efficiency. |
