摘　　要：传统的配电网络重构都是基于恒功率负荷来进行计算的,该方法对负荷电压特性的敏感程度较弱.针对上述缺点提出了一种基于负荷电压特性的配电网络重构方法,在每次的潮流计算迭代中对初始负荷进行一定程度的修正,从而反映负荷电压特性对配电网络重构的影响.设置配电网辐射状网络的生成判定原则,建立了以最小网损为目标函数的重构模型,并采用改进二进制粒子群算法进行寻优,得到重构结果.最后以IEEE 33节点配电系统为重构算例,验证了算法的有效性和正确性,并比较了负荷电压特性对重构结果的影响.Traditional distribution network reconfiguration is calculated based on constant power load; the method of load voltage characteristics sensitivity is weak.In light of the above disadvantages,this paper puts forward a kind of distribution network reconfiguration method based on load voltage characteristics.Each iteration of power flow calculation this paper changes the initial load to a certain degree of correction; thus the reaction load voltage characteristics’ influence on the distribution network reconfiguration.Setting radial distribution network generated judging principle,establishing the minimum network loss as objective function reconstruction model,and through the improved binary particle swarm optimization algorithm in optimization,the reconstruction results are obtained.Finally,this paper uses IEEE 33 nodes distribution system for refactoring example to prove the correctness and the effectiveness of the algorithm,and comparing the load voltage characteristics’ influence on the reconfiguration results.
