Abstract
Electricity is an important driving force of urban development, network planning and reasonable access to a huge social and economic benefits. The current urban power grid there is a structural weakness, poor reliability, power equipment, aging, high line losses, power quality unstable, low degree of automation issues, which the State made a big gap between the construction of smart grid, so the power grid Planning must be enforced. This paper introduces the basic concepts of network planning and research status, and load forecasting of several commonly used summary classification. Innovative vision of the city and into the section layer load the idea of load calculation were established model of the layers, which are in load distribution results more detailed. Complex urban terrain strip Shaoguan, Shaoguan City is proposed to adapt to the development of distribution network planning objectives and principles, and medium voltage distribution network for urban problems in the solution are given. Shaoguan city in the pressure distribution has been the lack of rational planning, rational distribution of papers to the pressure of the problem with three options for example, through technical and economic indicators of the three programs compared to fabric made in accordance with the multi-point, small capacity, short radius of the principles of layout, distribution network to reduce line losses, improve voltage level of the user, access to better social and economic benefits. Finally the effectiveness of the overall planning of the technical and economic assessment, analysis and economic benefits of its technical indicators, demonstrate the feasibility of this.
