Research Of Qionghai Power Grid Planning Facing Smart Grid

With economic development, grid planning has become an important part of the power of enterprise development, distribution network is the part closest to the user in the electricity network the scientific planning distribution network can improve the quality of power supply, power grid construction and transformation of rationality, has a decisive role in the security of grid operation economy. Therefore, building a safe, reliable, and coordinating all aspects of the development of the distribution network has become an important topic.First this article finishes distribution network status and needs analysis of Qionghai, the low-voltage distribution network as a research focus and resources from natural and geographical conditions overview of the history and current situation of social and economic development analysis, three aspects of socio-economic development planning, introduced the grid for the District Qionghai, analyzes in the low load, power consumption, etc., described the current situation in the low-voltage grid, analyzes the structure and power transmission equipment in the grid, and then pointed out the existence of some of the current grid Qionghai main problem to solve Qionghai distribution network problems, the city and the county areas of electricity demand forecasting, as the basis of a ring network planning to do. Secondly, the combined area "five" urban and social development plan, elaborated in low voltage distribution network planning as well as the general idea of partition construction and renovation ideas, through the medium voltage distribution network planning programs and low voltage distribution network planning scheme detailed analysis of the formation of the target grid and the program for detailed analysis. Finally, Qionghai distribution communication network present situation of power distribution and communication network design and planning program planning objectives of Qionghai distribution communication network modeling and analysis, research and compare the main power distribution network communication network technology, and ultimately determine Qionghai distribution communication network planning and construction of the overall program and the construction of the proposed construction route and draw results.
