[Abstract]:As the most developed area in the west coast of Pearl River Estuary and Guangdong Province, the demand for electricity load in Nanhai District of Foshan City is increasing rapidly. In recent years, the scale of grid investment has lagged behind the economic development, resulting in the bottleneck of economic growth in the South China Sea. As a terminal connected with users, 10kV distribution network is the most important part of the whole grid. Therefore, through the structure of the distribution network, the distribution points are continuously optimized to meet the needs of the new load to the greatest extent, which has become a key issue in the research of power technology in recent years. Based on the analysis of the existing substation and power grid in Foshan West Railway Station, combined with the report and installation of all the large users, the government carried out the load forecasting for the detailed planning of the area. In order to determine the planning and design plan of the medium and low voltage distribution network of Foshan West Railway Station hub, form the comprehensive project database of the new construction and transformation project, and on the basis of this, the investment estimation and economic comparison are carried out, and the final scheme is determined according to this. In order to solve the problems existing in the distribution network operation of Foshan West Railway Station, and meet the load demand of the new users. The contents of this plan include: analyzing the operation status of 10kV distribution network in Foshan West Railway Station, forecasting the power network load before 2020, determining the technical guidelines of planning and design basis, completing the new construction and rebuilding scheme, and so on. First of all, the operation status of 10kV distribution network in Foshan West Railway Station is analyzed, including the operation and maintenance of 10kV distribution network and key equipment indicators, the statistics of service time of various equipment, the load rate of higher power supply. Superior power supply 10kV cabinets use analysis and other content. Through the statistical analysis of the above indexes, it can be concluded that the grid structure is reasonable, the operation condition of various equipments is good, whether the distribution of power points and the power supply radius meet the requirements, whether the load borne by higher substations is reasonable or not, and so on. In order to determine the direction and thinking of the distribution network planning plan of Foshan West Railway Station. Secondly, according to the loading situation of all the large users such as Foshan West Railway Station, the government forecasts the detailed planning of the area, including the maximum load demand of the 10kV distribution network and its superior power supply, and the forecast of the actual load utilization rate and so on. The total power supply, the position of the power point and the topology of the power supply are determined by the prediction results. Finally, determine the detailed new, reconstruction program. The specific contents include power supply capacity, position and construction time, line direction of 10kV line and transformer capacity, distribution room, switch room and other equipment distribution points, and finally form a complete new construction, transformation scheme, etc. And complete the corresponding project library.
