Construction of Analysis Models Applied in Secondary Grid of Medium Voltage Distribution Network

Since the grid structure of 10kV distribution network has always been in a complex and chaotic state, this paper did some research to effectively standardize it. Firstly, the backbone grid and the secondary grid of 10kV distribution network are presented and defined. Then, based on the grid structure and functional characteristics of secondary grid, three types of analysis models are established to satisfy different requests. At length, considering actual construction and operation situation of a certain city, boundary conditions for various parameters are settled down before analyzing and calculating corresponding models so that the correctness and effectiveness of the proposed method can be validated.
