Abstract 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.
