12th Five-Year Power Network Development Rolling Planning Of Neixiang County Supply Area

Electric power grid is an important part of the power industry development. A good power grid can achieve the electric balance between supply and requirement, optimize the electrical source distribution, and support each other between the regional power grids. Power network planning is a major component of the city development planning, which is tremendously significant to make progress in the district economy and society.The county level city economy has grown rapidly in recent years, which demands the electric energy more and more. Every year, a great deal fund is needed to put into the electric construction. Therefore, the work on the rolling planning of the power grid is very important, which assure the expansion of the county level electrical network scientifically and orderly, and meet the economy and society development in many countries.The Neixiang county power network planning, and has a discussion on some problems, such as the present state of the county level power grid, electrical load forecast, substation site optimization, planning principle, future structure during the 12th Five-Year Plan; investment evaluation, and analysis of comprehensive benefit, etc is the main work of this paper. Aimed at the power operation steadily and safely, and aimed at the increase load demand, the 110kV network will be improved and strengthened; the 35kV network will be optimized sub-regionally, and the distribution power network of the county and villages will be accelerated. All these can provide solid guarantee for the economy. This plan will realize the urban-rural coordination, the electric transmission-distribution cooperation, and the building-alteration cooperation. Based on the electricity demand of Neixiang county, the plan considers a series of problems, such as the recent demand and future program, coordinated development, moderate advancer, and uniform standard, so the plan is authentic and operable, it can satisfy the local future electricity demand, and make the regional power network steady, reasonable, safe and high-efficiency, which has guiding significance and practical value.
