【摘要】：配电网是连接用户与主网的中间部分,随着经济的发展,用户对配电网供电能力要求越来越高,配电网的建设不可能一劳永逸,每过一段时间需要重新对配电网的结构及供电调设备进行相应的规划和调整。配电网的供电可靠与否将直接影响用户的用电体验,因此对配电网进行合理规划,提高配电网的供电可靠性与经济性,具有十分重要的意义。在分析配电网规划的背景和意义的基础上,首先对唐山地区高压、中压、低压配电网的结构进行分析,并详细分析高、中、低配电网设备如线路、变电设备运行及负荷情况进行分析,并找出目前唐山地区高压及中压配电网中存在的主要问题;在对唐山地区历史用电量分析的基础上,对未来五唐山地区的电力需求形势进行分析,并对唐山中心区、开平区、古冶区、海港开发区的电量预测,并分别进行远景、近景负荷预测,为唐山地区配电网的规划奠定基础。研究配电网规划的目标及技术原则,并针对唐山地区配电网现状,给出适合唐山地区110kV、10kV、380V配电网的技术原则,确定了220kV配电网、110kV配电网的及唐山四个区(中心区、开平区、古冶区、海港区)的规划方案,确定了唐山地区配电网的变电站数量、变电站位置等。最后给出了唐山地区配电网规划的投资估算。
[Abstract]:Distribution network is the middle part of the connection between users and main network. With the development of economy, the power supply capacity of distribution network is becoming more and more high, and the construction of distribution network cannot be done once and for all. It is necessary to plan and adjust the structure of the distribution network and the power supply regulation equipment for a period of time. Whether the distribution network is reliable or not will directly affect the user's experience of using electricity. Therefore, it is of great significance to plan the distribution network reasonably and improve the reliability and economy of the distribution network. On the basis of analyzing the background and significance of distribution network planning, the structure of high voltage, medium voltage and low voltage distribution network in Tangshan area is analyzed firstly, and the high, medium and low distribution network equipments such as line are analyzed in detail. This paper analyzes the operation and load of substation equipment, and finds out the main problems existing in the distribution network of high voltage and medium voltage in Tangshan area at present, based on the analysis of historical electricity consumption in Tangshan area, This paper analyzes the situation of electric power demand in Wutang Mountain area in the future, and forecasts the electricity quantity of Tangshan Central District, Kaiping District, Ancient smelter area and Harbour Development Zone, and carries out the forecast of prospect and close-range load respectively. For Tangshan area distribution network planning laid the foundation. The goal and technical principle of distribution network planning are studied. According to the present situation of distribution network in Tangshan area, the technical principles suitable for distribution network of 110 kV / 10 kV / 380V distribution network in Tangshan area are given, and the 110kV distribution network of 220kV distribution network and four districts (center area, Kaiping area) of 220kV distribution network are determined. The number and location of substation in distribution network of Tangshan area are determined. Finally, the investment estimation of distribution network planning in Tangshan area is given.
