| 摘 要： | 在简要分析已有配电网潮流算法的基础上,提出了一种改进的带二阶项的快速潮流算法.该算法应用矩阵分块求逆方法对阶数较高的雅可比阵求逆计算进行了改进,使阶数较高的雅可比阵的求逆变为阶数较低的四个阵的求逆.在充分发挥带二阶项的快速潮流算法收敛性好的基础上,提高了计算速度,适用于各种复杂的配电网络,并基于该算法开发了配电网潮流计算软件.27节点和33节点算例计算结果表明,该方法具有良好的收敛性,能很好地处理配电网重构,具有较高的计算速度.

| Abstract: | After analyzing power flow algorithms, a fast load flow algorithm based on algorithm including second order term is proposed . Using sub-matrix inverse calculation , this algorithm improves the inverse calculation method of high term Jacobian matrix. By breaking Jacobian matrix into four sub-matrixes, the algorithm simplifies the inverse calculation of Jacobian matrix . This algorithm has good convergence as second order term fast algorithm.It improves calculation speed and can be applied to the complex distribution network.. A distribution power flow software based on the improved algorithm is developed. This improved algorithm has been tested on the 27-node and 33-node systems. The results show that it has better convergence,and can deel with distribution systems with loops and has more fast calculation speed. |
