Distribution network load down or line maintenance , usually related to the co- loop operation , but during the loop closing operation may have a greater steady-state current as well as the impact of current in the grid , which will directly affect the security and stability of the grid operation. In view of the above features , the use of a professional software system modeling and simulation, before the loop closing operation by system simulation on the cyclization operation play a guiding role , has a strong research and practical value . This paper presents a simplified model of distribution network loop closing operation , carried out a detailed derivation of the calculation of co- the ring steady-state current and inrush current . The cyclization trend a detailed analysis to identify the factors that affect cyclization current loop closing point voltage by adjusting the capacitor compensation and transformer tap to change the ring closing point voltage thereby reducing the co- ring current , together the ring current limit . Loop closing operation to have a more comprehensive study , the Daxing some line loop closing modeling and simulation and computational analysis .
