摘要
针对放射式配电网潮流计算中广泛应用的前推回代法对支路和节点编号的要求,结合图论关于节点的度的概念,提出依次将与度为1的节点相连的支路移入计算次序表,然后利用前推回代法依次计算各支路电流和节点电压的算法,并且经过简单处理便可适用于多电源环网供电配电网络。该算法简洁明了,编程方便,简便有效,对算例进行测试计算,验证了该算法及其程序正确。
According to the need of branch and node numbering of back/forward sweep method widely used in load flow calculation of radial distribution network,this paper presents a new method.With the concept of the degree of node in graph theory,move the branch related with a node whose degree is 1 to the calculating sequence table in order,and use back/forward sweep method to calculate the current of every branch and voltage of every node step by step until convergence.With simple modification,this method can be easily used in the looped distribution system.The method is concise,efficient and easy for programming.In IEEE 33 bus system the proposed method has been tested.
