Reform and opening up more than 30 years, China’s economic construction has achieved remarkable tremendous achievements. The improving infrastructure and continuously improve people’s living level. In our country’s economic construction achievements of the electric power industry, China has made great progress. Electric power industry is the foundation of a country’s economic construction industry, power industry development, has no reliable electrical infrastructure and advanced technology, the power will be seriously hinder the further development of economic construction and improvement of people’s living standard. The distribution network construction is safe and reliable electricity transmission to end users. The distribution network planning is a city in the power supply enterprise is an important work, in order to obtain the biggest economic benefits, the distribution network planning to ensure the safe and reliable network, and to ensure the economic operation of the power grid. Based on JiNing urban distribution network planning for empirical case are analyzed in detail, in JiNing power source and load distribution and power, and low voltage distribution network based on the present situation of low voltage distribution network, summed up these problems. Through the analysis of scientific data, using linear regression model, the index model and the logarithm model to predict JiNing municipal science in future years, for the power load obtained.after planning to lay the foundation. Then this follow the general goal of distribution network planning, overall thought and use of scientific planning and transformation method, preliminary design JiNing out of the city, and low voltage distribution network planning scheme. Finally, this paper respectively from the Angle of technical project planning, economic benefit and social benefit view Angle from three aspects, levels and the classification of project planning overall plan made evaluation. Evaluation results show that: the technical efficiency, after renovation, distribution network planning in the power supply reliability and quality of power supply and power grid structure, equipment reliability technology, can bring the comprehensive promotion has achieved very good technical benefit. In the economic aspect, although project itself from the financial indicators, the project not profit, but the power supply enterprise as a social foundation construction is the important component of its social functions at the same time fully fulfill will produce immeasurable social benefits, And in the social benefit evaluation, planning, distribution of can largely increase user, industry, improve the economic benefits, improve customer satisfaction, the comprehensive benefits, boosting the development of local economy and reducing environmental pollution and beautify cities, improve the city’s investment environment.
