| Economic development,the power required in advance.Electricity is the power of the national economic development.A good power grid planning must be in city planning and development of the national economy of urban space resources comprehensive utilization planning rely on,so that it can make the power grid planning project of great social benefits and economic benefits.The accuracy of the science of electricity load forecasting is the basis for development of network planning and critical power demand forecast should be adapted to the needs of and appropriate advance national economic and social development.Suitable for power grid development target and actual situation of power grid construction planning principle is the power grid project benefit the biggest change based.At present the main power planning fall into three categories,the first kind is based on urban spatial resources,combined with the space distribution of electric power network special planning;The second type is based on the industry management,project construction project planning five years in power;The third type is based on the systematic analysis project construction planning;As the electric power industry management of the power grid planning should be in line with the power grid and the power to plan as a whole,the coordinated development of the principle to load distribution,power supply,planning and urban spatial resources as the basis for a work,planning mainly divided into three parts,electric power load forecasting,power grid planning principles,and the sequence of construction projects.This paper according to the Shenzhen "Twelfth Five-Year Plan" power grid planning subject,in the electric power load forecasting,combining with the local social and economic development plan,fully research and analysis of the historical electricity supply,social and economic development and the relationship between the power,using a variety of methods from different angles and prediction,the comprehensive method of weighted the results of the final planning get value to guide the project construction.This paper based on the previous grid development experience in Shenzhen.According to the proposed by Shenzhen power grid resource conservation and environment friendly target built for the intelligent,efficient,reliable,the international first-class green power grid,then proposes the planning principle of Shenzhen characteristics.Research results based on forecasts of electricity demand,combined with the grid in the construction work and power of the preliminary work,determined in accordance with the principle of network planning,focus on the Shenzhen "Twelfth Five-Year Plan" substation distribution planning,the main network programs based on PSD platform,the proposed grid development Goals and "Twelfth Five-Year Plan" year by year the power grid construction program,and related electrical checking,investment in power grid construction and planning and assessment of the grid. |
