Study On Distribution Network Planning Based On Regional Demand Forecasting

Reasonable distribution network planning can make rational use of power resources, but also can optimize the investment, to avoid duplication of construction, repeat investment, scientific distribution network planning is very important, high-level distribution network planning is the current power grid enterprise Urgent to solve the problem. Based on the current situation of Dongning County, Mudanjiang City of Heilongjiang Province and the national economic development, this paper conducts a study on distribution network planning based on regional demand forecasting.Firstly, the principle and basis of this 66 kV and 10 kV distribution network are determined, the current situation of Dongning County power grid is analyzed and the main problems of distribution network in Dongning County are identified. Based on the data of "12th Five-Year Plan", To carry out power load forecasting, the use of elastic coefficient and other methods of comprehensive comparison, forecast Dongning County society as a whole electricity consumption; use of maximum load hours to meet the maximum load forecasting requirements. According to the load characteristics of Dongning County, the plan of distribution network is made according to the power supply area and the voltage level, and the rationality of the planning scheme is proved by the planning effect analysis. The optimization design of power network planning is put forward. From the increase in capacity to meet the load capacity development needs to improve distribution grid structure and other aspects of planning, distribution network level more clearly. And gradually eliminate power supply "bottleneck", and constantly improve the level of power equipment, step by step out of high-loss equipment, the promotion of advanced technology and mature, economical and reasonable, cost-effective distribution network equipment.Through the distribution network planning research.The first is to improve the power network in Dongning County, the lines of each other to enhance and improve the reliability of power supply, power point construction to meet the requirements to shorten the power supply distance, load distribution of science, can reduce the distribution network energy loss. Second, reduce costs and improve business efficiency. The implementation of this plan for the distribution network, Dongning County, an effective reduction of power loss, reduce distribution network failure, reducing the cost of personnel, reducing the loss of power to improve the unit price, bring direct economic benefits; power supply capacity to meet New user needs, the increase in electricity sales brought about economic benefits. The third is to increase the overall social benefits. Strengthen the construction of distribution network to meet the country's macro strategic needs to protect the social and economic stability and development. The fourth is to promote the successful experience of this article. With the help of Dongning County power distribution network planning achieved tangible results, in the Mudanjiang area under the jurisdiction of the six cities and counties to promote a comprehensive, so that the results of comprehensive application.
