摘　　要：针对配电网重构问题,提出了用一种基于方向信息素的改进蚁群算法来求解。该算法给出了新的信息素更新策略,并加入探索率因子的支路选择策略,从而加快蚁群算法的收敛速度和控制精度,防止算法陷入局部最优。通过仿真实验表明,基于方向性信息素的改进蚁群算法在配电网重构问题中能够进行有效的应用,且在求解问题时具有很快的收敛速度,同时能够求出较优的解。To solve the problem of distribution network reconfiguration,an improved ant colony algorithm was proposed. It is an algorithm that has a new pheromone updating strategy and slip selection strategy with the factor exploration rate,which promote convergence speed and control accuracy of ant colony algorithm and prevent the algorithm from falling into local optimum. The simulation results show that the improved ant colony is applied effectively with fast convergence rate and is able to obtain optimum solution to solve the problem of distribution network reconfiguration.
