Research Of Yue Guan Qian High Speed Railway Economic Cooperative Experimental Zone

The Guangdong-Guangxi-Guizhou High-speed Railway Economic Zone Cooperation Experimental Zone is an important platform for cooperation in the Pan-Pearl River Delta region.It is a “forward position” for the Pearl River Delta to radiate the Southwest and a “bridgehead” for the integration of the Southwest in the Pearl River Delta.With the gradual development of the development and construction of the pilot area.It will inevitably bring about rapid growth in the use of electricity.The speed of planning and construction of the power grid lags behind the speed of load growth and becomes a factor that restricts economic development.This article starts with improving the scientificity,pertinence,and operability of the power grid planning,and analyzes the existing medium-voltage grid in the Guangdong-Guangxi-Guizhou High-speed Railway Economic Belt Cooperation Experimental Zone,combining all large-scale user reporting requirements and government-to-center The planning of the urban area carries out the load forecasting results and combines the development trend of the smart grid and the emerging comprehensive energy sources,and determines the planning and design plan of the medium-low voltage distribution network in the Guangdong-Guizhou-Hebei High-speed Railway Economic Belt Cooperation Experimental Zone,and forms a new-build and renovation project library,and on this basis On the basis of investment estimates and economic comparisons,the distribution network structure was optimized to solve various problems in the current operation of the power grid,and to meet the user’s demand for reporting.In this paper,the power grid planning work of the Guangdong-Guangxi-Guizhou High-speed Railway Economic Belt Experimental Area mainly includes the following aspects:First,the status quo of distribution network is analyzed by collecting data and indicators of distribution network operation and equipment in the Guangdong-Guangzhou high-speed railway economic zone.The process includes statistics on the number and usage time of existing distribution network equipment,analysis of operating status,utilization analysis of 10 k V line interval,analysis of the operation status of 10 k V lines,transformers and other medium-voltage distribution network equipment.Through the analysis and arrangement of the above items,it is concluded whether the layout of the distribution network is reasonable,whether the radius of the power supply satisfies the requirements of the area,whether the load balance is reasonable,etc.,and the planning plan and the next work plan are determined.Second,10 k V load forecasting is conducted for the Guangdong-Guangxi-Guizhou High-speed Railway Economic Zone.Based on the government’s plan,the area of ??land that can be developed,and the nature of its development,the planned growth of the regional distribution of blocks in the Guangdong-Guangxi-Guizhou High-speed Railway Economic Zone is analyzed,which serves as a basis for division of power supply partitions,wiring,and scope of determination.Thirdly,in accordance with the development trend of smart grids and emerging comprehensive energy sources,the planning principles for proper distribution automation,distributed energy access,and micro-grid construction will be formulated in the Guangdong-Guangxi-Guizhou High-speed Railway Economic Zone pilot zone.Fourth,determine the planning and reconstruction program.The specific content is 10 k V line location,10 k V power distribution plan,complete 10 k V distribution network planning research in the test area.
