| In this paper, firstly the character of distribution network and requirement to the algorithm is analyzed. Then,creates the model of the power flow of the distribution network. The development of methods for load flow solution of distribution network at present have been fully analyzed and evaluated in the aspect of convergence. A current flow based back/forward sweep algorithm is studied in detail; the breath-first paradigm is as the theoretical basis. According to the specific situation, two sub-networks of distribution network are elected to calculate power flow. MATLAB 6.5 accomplishes the power flow program of distribution network, which based on back/forward sweep algorithm. LabVIEW 7.0 is used to create interfaces by which the project workers can gain information timely and convenience. The results show that this algorithm has superiority and exploited software has practicability.
