基于节点不平衡功率的病态潮流算法

The Ιll-Conditioned Load Flow Algorithm Based on Node Lopsided Powers

提出了基于节点不平衡功率的病态潮流算法,将潮流方程转换为非线性规划的形式,与普通的潮流计算相比较,计算量增加不大;对于由潮流计算初值不合理、潮流方程无可行解等因素引起的潮流病态现象有很好的收敛性.经过IEEE-30节点系统在几种情况下的计算比较,证明该算法是非常有效的.

The new ill-conditioned load flow algorithm based on node lopsided powers was proposed by transforming the power flow equations to non-linear programming. It has the all-right astringency for ill-conditioned load flow arisen from the beginning value and no feasible solution in the power flow calculating progress and has less calculating cost compared to traditional power flow calculation. The case study was made at an IEEE-30 nodes system and the validity was proved.
