摘要
在已有的配电网前推回代法基础上,提出了适用于少环辐射配电网的一种潮流计算方法.首先,利用叠加原理将少环辐射网分解为纯环状网和纯辐射网,分别对其进行潮流计算,并将两个网络的潮流进行叠加,求解整个网络的潮流;其次,采用前推回代法进行少环辐射网潮流计算,给出了算法流程,并针对一28节点算例采用C语言编制程序进行计算.结果表明该方法具有收敛速度快,迭代次数少,运算效率高的优点.
According to the structure feature of the weakly meshed distribution network,a power flow method based on the superposition principle is proposed in this paper.The network is firstly divided into two networks based on the superposition principle：one is the pure radial network and the other is the pure meshed network.Power flows are solved respectively in the two networks,then power flow calculation is obtained by superimposition the power flows of the two networks.The back/forward sweep method are employed for power flow calculation and the algorithm process.The presented method is tested by 28 nodes system which programmed with C language.The results indicate that the proposed method can save memory and has good convergence performance and high efficiency.
