| Power grid planning for the long-term development of the electric power enterprises play an important role,is an important part of national economy and social development,the foundation to support role to the development of the whole country.The role of the power grid planning is to make the future development of power grid construction of adaptation,meet and advance in the planning of the region’s economic development needs,and can play its for power grid construction,operation and the leading and decisive role of the power supply security,reasonable investment plan at the same time,improve the investment benefit.According to the provincial company during the period of "much starker choices-and graver consequences-in" to the overall requirements of power grid construction,according to the basic situation and satisfy A county power grid planning and construction of A county power grid during the "much starker choices-and graver consequences-in planning to achieve improvement and optimize the structure of A county power grid,grid security and harmonious development of construction and reform in urban and rural areas,reduce network loss,improve power supply reliability and power quality and realize the intelligent power grid,the construction can meet the needs of load growth and clear structure,rational layout of the strong power grid,in order to satisfy A county for national economic and social development demand for electricity.This article first introduced the thesis research background with meaning;Then introduces the status quo and analysis of A county power grid status quo and existing problems,according to the actual load characteristics in data description with the load characteristic curve,and the influence factors are analyzed.Then introduces the overall train of thought and method of load forecasting,mainly introduced in this paper,the use of the comprehensive utilization level of method,the electricity elasticity coefficient method and multiple linear regression method,the key users and power load forecast of 2015-2020,according to the nature of electricity and the geographical position,power balance partition calculation;According to the electric power balance calculation result for 220 kv,110 kv variable capacitance balance calculation,given two sets of construction scheme and recommend a solution,in accordance with the technical requirements for the substation putting the stationing plan;Zhu Wang Jia by substation location location,plan,ensure reasonable trend of sexually transmitteddiseases to meet the needs of the development of the economy and presents the points in the power grid construction investment;Finally combining state of the smart grid construction,intelligent power grid construction of A county put forward three special planning,distribution automation planning,special planning,intelligent power electric vehicle charging pile district planning. |
