Study On The Distribution Network Planning In The Grid Of Yuhang District

To address weaknesses in the grid of Yuhang District and optimize network structure and improve both power supply capacity and adaptability and achieve immediate and long-term convergence combined with construction and renovation as well as facilities to achieve standardization and standardization of grid connection. Combling with economic development needs of Yuhang District, this paper did a comprehensive analysis and research about the actual situation in the grid of Yuhang District, and proposed a feasible solution about the distribution network planning in the grid of Yuhang District. And the details are as follows:1. This paper conducted a comprehensive survey and analysis about the current situation of distribution network in Yuhang District, and did a survey about the power settings and the substation and the power lines and other conditions of distribution network(110kV and below the grid) in Yuhang District.2. This paper did a reasonable forecast about the power demand of Yuhang District for the next few years. Projected to2015, the power consumption in Yuhang District will reach8.24billion kwh, and the maximum load of region will reach1700MW in which1512MW of the110kV network and130MW of the35kV network and1310MW of the1OkV network.3. Based on the above reseach, this paper proposed a feasible option of the distribution network planning of Yuhang District. The plan included substations and power lines and distribution transformers and switching stations’ new constructions and rehabilitation programs in110kV and35kV and10kV three voltage levels grid.Through this planning study which guides the high voltage distribution network construction and renovation of Yuhang Power Supply Bureau, the city can ensure high voltage distribution network construction and economic development and municipal construction for a coordination. And also get a promotion of the city’s high voltage distribution network moderate advance development and a effective improvement of the city’s medium voltage distribution network structures. This will ensure high quality and reliable power supply to the community and residents.
