摘要
随着我国社会用电需求量的增多,配电网在分配电能中的作用更加显著,其关系着整个电力系统的运行效率。城市中压配电网特别是10kV配电网的接线方式关系到如何迅速、准确地处理配电网的事故,使配电网和用户损失达到最小;如何更为及时正确地处理用户投诉;如何进一步提高供电可靠性等这些亟待解决的一系列问题基础就是配电网的网架结构。电网网架结构的正确与否直接关系着线路电网供电性能的发挥。常见的配电网接线模式有辐射、双射、单环、双环、#字形、平行直供、两供一备、4×6网络。
Along with electricity demand increased,Distribution Grid（DG） has significant action in the distribution of electric energy,it relations with the operating efficiency of the whole electric power system.The grid structure of 10kV DG is special in urban medium voltage DG.How quickly and accurately to handle the accidents of DG,which can reduce loss of DG and users to minimum;how to deal with users complaints more timely and properly;how to improve the reliability of power supply,these series of problems is based on grid structure of DG.Correct grid structure is related to the play of power supply.The common grid structures are radiation type、double shot、single ring、double ring、#glyph、parallel direct supply,two for one,4x6 network.
