The research on the layout mode of the main network and the secondary network of the diamond distribution network

Aiming at the problem of the lack of the research on the coordinated layout mode of the switch station and the ring station in the development of the diamond distribution network proposed in the Shanghai area, it constructed the Shanghai diamond distribution network collaborative layout mode of the main and the secondary network. Firstly, it introduced the wiring mode of the diamond distribution network, and equivalented the power supply range of the substation into a regular hexagon, and established the diamond-shaped power supply model of the diamond distribution network, and analyzed the factors in the layout mode of the main and the secondary network in the diamond distribution network; Secondly, it constructed the layout model of the main network in the diamond distribution network considering the combination of reliability and economy;Finally, within the power supply range of the switch station,it constructed the layout model of the secondary network in the diamond distribution network considering the combination of reliability and economy. In the end, the best layout model of the main and secondary main network of the diamond distribution network was obtained, which provided the quantitative support for the planning of the diamond distribution network in Shanghai, and gived the guiding significance.
