Low Voltage Distribution Network Planning Of Yingde City

Yingde county is the largest Administrative Region in Guangdong Province with the Ministry of land area, located in the Pearl River Delta and the mountains of northern guangdong. Yingde City in low voltage distribution network has typical characteristics of rural and mountainous area power grid, low and medium voltage distribution network in historical debts more, equipment aging a remnant of the old, the power supply capability of distribution network is weak. And because the Anglo German large geographical area, the higher power distribution problems, resulting in low and medium voltage distribution network of power supply radius is generally too long, with the continuous improvement of the level of social economy and the farmer living standard, low and medium voltage distribution network in the city’s power supply ability and the quality of power supply has been far can not meet the needs of living and production, especially in rural low voltage distribution network to transform the problem of low have become increasingly prominent.With the rise of the "reform of the Pearl River Delta development plan," as a national strategy, part of the Pearl River delta industry will be transferred to the surrounding area, the "double shift", "Fu County town and all to the city of Yingde bring significant new development opportunities. In view of the functional location and economic development trend of Yingde, the existing power grid facilities and conventional power grid construction pace has been clearly not meet the needs of industrial development in Yingde City, residents with electricity load growth.This paper is based on the "Twelfth Five Year Plan" period, the relevant data of the calendar year, in Yingde "Twelfth Five Year Plan and detailed report" as the basis, to strengthen the interaction between power grid planning and local economic development planning, to ensure that the "Twelfth Five Year Plan" to determine the planning objectives and planning achievements. In this paper, the current situation of Yingde power grid is introduced and summarized, the key to find out the causes of the development of the city’s middle and low voltage power distribution network, to find the measures to improve the power supply capacity and the level of the low voltage distribution network. In this paper, the load forecasting of Yingde city is carried out by using the electric load. This paper in Yingde City Power Grid status analysis and power load forecasting based on, to further clarify the Yingde City low and medium voltage distribution network planning technology principle, according to the existing problem of priorities for the planning of distribution network construction and transformation project, and ultimately determine the Yingde City between 2015~2017 in low voltage distribution network planning and construction scheme and of the plan, in low voltage distribution network construction and transformation, reflecting in low voltage distribution network planning of the forward-looking and scientific.
