The distribution power flow calculation is the basis of distribution network planning, network analysis, troubleshooting. On the base of the existing distribution network power flow calculation method, aiming at structural features for the distribution network, a hierarchical model for the distribution network topology analysis algorithm is applied to the distribution network flow calculation. Through the algorithm, distribution network branch will be classified hierarchically , a matrix approach to building network topology model with the branch hierarchy matrix of forward and backward substitution method to calculate the power loss of each branch and the node voltage, numerical results show that expression of the algorithm is simple, clear concept, convenient and practical.
