【摘要】：电网规划是经济社会发展规划的重要组成部分。一个科学、经济合理的电网规划不仅可以指导电网未来的建设和发展,提高电力系统的供电能力和可靠性,满足人们生活和经济社会发展对电力的需求,而且能够取得良好的经济效益和社会效益。同时,能源结构和用电结构的变化、电力负荷的快速增长以及对供电可靠性要求的不断提高,又对电网规划提出了诸多新的挑战。本文以当前芮城县历史用电数据为导向,通过数据分析,掌握历史负荷量。根据近些年历史用电负荷数据,在统计基础上采用基本灰色预测模型对预测年负荷进行估计,并与实际值作对比论证该预测模型的有效性。根据芮城县的经济发展状况,本文采用用电单耗法,负荷密度法,结合时间序列拟合和基本灰色模型的方法,对芮城县未来的工业用电,居民用电进行预测分析,并结合配电网现状进行整体的配电网规划。首先从用电量的最大负荷量,以及芮城县未来规划年的用电量分析中可以得到,高压电站无法满足当前芮城县城市居民与经济发展建设的需求,需要加快高压电站建设投入。根据芮城县未来的发展,以及用电情况,提出了芮城县的电网规划改造方案。变电站的分布规划,由先前的10个高压电站区域,变为13个高压电站区域。根据地理环境,决定添加110kV的阳城变电站,柴涧变电站,古仁变电站等相应的设施。其次,依据芮城县110kV变电站规划布局,在百梯山,董村建设35kV变电站2座。通过对高压变电站的建设,将可以有效的提升芮城县的高压的负载能力。在线路上推荐双链中的T、π混合结构作为目标网架。通过上述的规划改造方案的实施,以此来满足未来芮城县工业以及居民生活用电的需求。最后,根据芮城县电网建设的特点,提出了提高芮城县电力质量水平的措施。该措施从技术以及管理的角度出发,论述了电网短路,线损,以及可靠性控制的方法,以此来提升芮城县的电网电能质量水平。
[Abstract]:Power grid planning is an important part of economic and social development planning. A scientific, economical and reasonable power network planning can not only guide the future construction and development of the power grid, improve the power supply capacity and reliability of the power system, but also meet the needs of people's daily life and economic and social development. And can achieve good economic and social benefits. At the same time, the changes of energy structure and power consumption structure, the rapid growth of power load and the continuous improvement of power supply reliability, also put forward a lot of new challenges to power network planning. Based on the current historical power consumption data of Ruicheng County, this paper grasps the historical load through data analysis. Based on the historical load data of recent years, the basic grey forecasting model is used to estimate the predicted annual load, and the validity of the forecasting model is compared with the actual value. According to the economic development of Ruicheng County, this paper uses the power consumption method, the load density method, the time series fitting and the basic grey model to forecast and analyze the future industrial and residential electricity consumption in Ruicheng County. And combined with the distribution network status of the overall distribution network planning. Firstly, from the analysis of the maximum load of electricity consumption and the future planning year of Ruicheng County, it can be concluded that the high-voltage power station can not meet the needs of the current urban residents and economic development in Ruicheng County, so it is necessary to speed up the investment in the construction of the high-voltage power station. According to the future development of Ruicheng County and the situation of electricity consumption, this paper puts forward the plan of grid planning and renovation in Ruicheng County. Substation distribution planning, from the previous 10 high-voltage power station area, to 13 high-voltage power station area. According to the geographical environment, it is decided to add the corresponding facilities such as Yangcheng Substation, Chaijian Substation, Guren Substation and so on. Secondly, according to Ruicheng County 110kV substation planning layout, in Bateshan, Dongcun construction 35kV substation 2. Through the construction of high-voltage substation, it can effectively enhance the high-voltage load capacity of Ruicheng County. The T-, 蟺 hybrid structure in the double chain is recommended as the target grid on the circuit. Through the implementation of the above planning and transformation program, to meet the future Ruicheng County industrial and residential electricity demand. Finally, according to the characteristics of Ruicheng county power grid construction, the measures to improve the power quality level of Ruicheng County are put forward. From the point of view of technology and management, this paper discusses the methods of short circuit, line loss and reliability control in order to improve the power quality of Ruicheng County.
