[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.
