【摘要】：为简化大规模配电网络编号步骤和提高潮流计算速度,在广度优先搜索编号的基础上,提出了改进的节点编号方法。此方法对于新增分支并不需要考虑同级网络的分支数,只需在父节点的基础上直接添加编号,应用配电网络的代数方程计算出配电网络各台区节点电压值和功率分布。经VBA预处理和Matlab编程对5级中压开式配电网络进行潮流计算测试,整个配电网潮流计算结果在满足配电网潮流计算精度要求的前提下,相比改进前广度优先搜索编号方案计算速度快,验证了该编号方案的有效性和实用性。
[Abstract]:In order to simplify the numbering steps of large-scale distribution networks and improve the speed of power flow calculation, an improved node numbering method is proposed on the basis of breadth-first searching for numbering. This method does not need to consider the number of branches of the same level network for the new branch. It only needs to add the number directly on the basis of the parent node and calculate the voltage value and power distribution of the distribution network nodes by applying the algebraic equation of the distribution network. Through VBA preprocessing and Matlab programming, the power flow calculation and test of 5 stage open medium voltage distribution network are carried out. The results of power flow calculation of the whole distribution network meet the requirements of the power flow calculation accuracy of the distribution network. Compared with the improved breadth-first search numbering scheme, the efficiency and practicability of the numbering scheme are verified.
