A Practical Method for the Optimization of Radial Distribution Feeders

提出了一种确定辐射配电线路最佳布局的实用方法——局部调整法,并给出了辐射线路潮流及线路最大电压损耗的简易计算方法,编制了微机程序,便于在实际中推广应用。

An efficient algorithm for the optimization of radial feeder configuration—lo- cal regulated method is presented,which is based on simple graph manipulations.The method is in the way of changing branch to minimize the annual cost of the radial feeder,that allows all demands to be satisfied subject to branch capacity and node voltage constraints.By use of incidence matrix of radial network,a simplified method for the calculation of load flow and voltage drop is also given.Having been programmed on microcomputer and used in practical distribution system planning,the method shows its feasibility and efficiency.It can be widely used in search for optimal radial feeder configuration and can provide the planners guiding information in the decision making process.
