A Discussion On Small And Medium-sized Towns Grid Planning Considering The Assessment Of Environmental Impact

Network planning is an important part of the electricity the previous work, is the decisive factor in the level of power grid operation and economic and social benefits. Environmental impact assessment indicator system on the network planning study, consider the environmental impact of the whole life-cycle management background, the planning grid comprehensive evaluation system andthe mathematical model, and model recommended connection mode of distribution network planning for the future distribution network planning offers a typical plan.Distribution network planning, for example network planning theory and practicalmethods to consider the environmental impact assessment study and the small towns.Firstly, network planning environmental impact assessment theory and indicators tostudy the environmental impact assessment index system for the network planningstage. Network planning, identification of environmental impact, environmental impact assessment indicators system, and discusses the meaning of the evaluation,explain the application process of the index system should be noted that theproposed index system right Method of Determining.In this paper, consideration of environmental impact indicators for network planningcomprehensive evaluation of the utility grid system, refine the mathematical model ofnetwork planning based on life cycle management. The system considers thereliability, safety, environmental impact and economy, and each index can be solvedby commercial software, and thus to evaluate the results of versatility and authority.Full life-cycle assessment in the plan recommended the program to select theapplication to conduct a study to make a comprehensive analysis of medium voltage distribution network of a typical grid, and the recommended program.Consideration of environmental effects substation distribution planning theory andpractical methods based on grid comprehensive evaluation system of commence,propose a network planning sub-level, multi-objective optimization mathematical model, asked the planning process, to reduce the computation to planning efficiency and planning effects of the balance.The fifth chapter in a small town distribution network planning as an example a case study, to obtain good results.
