摘要
针对辐射状配电网网络拓扑结构特点,在传统前推回代法的基础上,提出了一种改进的前推回代法.利用非叶节点作为一条支路终节点的特点,在潮流计算前通过反复搜索叶节点和新叶节点,确定功率和电压的计算顺序,从而无需对配电网各支路分层,可对网络中节点任意编号,且计算过程简单、直观,适用于任意辐射状配电网的潮流计算.在MATLAB环境下对算例进行仿真分析,结果表明,提出的方法可行、有效.
Aiming at radial distribution network topology features,an advanced forward and backward sweep algorithm is proposed based on the traditional one.Using the characteristics of non-leaf node acted as an end node of the branch,we determine the power and voltage calculation order before power flow calculation by searching leaf nodes and new leaf nodes repeatedly.Nodes can be numbered randomly and branches need no layering.The calculation process is simple and intuitive which could be applied in any radial distribution network flow calculation.Analysising the calculation of the example by MATLAB,the result shows that the proposed method is feasible and effective.
