【摘要】 在电力网络中,配电网与电力用户的联系最密切,是连接供电电源和电力负荷的重要桥梁,对电力用户的供电可靠性、稳定性和电能质量也产生直接的影响。随着我国经济的持续发展,部分地区显露出城区配电网建设严重滞后的现象,电源建设和电力负荷发展过快的问题。本文从临汾城区配是网规划的现状出发,对配电网的规划进行了实际的研究。本文在总结当代项目管理思想的基础上：,将当前最新的项目管理方法与供电企业的实际情况相结合,阐述了配电网规划中推进项目管理的必要性和可行性。论述了现代项目管理理论在配电网规划方面的运用,对如何做好配电网规划项目管理的启动、计划、实施、控制、收尾等主要过程提出参照方法和各环节主要内容,科学合理的配电网规划项目不仅能够为供电公司节省大量人力物力,而且能够提高城区供电能力,满足用电增长需求；加快配电网建设改造,可以不断扩大配电网覆盖范围,满足城乡用电需求,逐步提高电能质量,指导中、长期城市配电网的建设与改造。优化配电网结构,适度提高配电网规划建设标准,完善城市重要用户的保供电措施,增强防灾、减灾能力。改善设备水平,从而有效提高可靠性,以保证向社会和居民的优质、可靠地供电。提高配电网运行的经济性。通过改造完善网络结构,加快更新残旧设备,降低网络损耗,提高运行经济性,提高电力企业的投入产出效益。所以,对城区配电网进行合理的规划和改造,是解决供电需求矛盾、提升供电可靠性的主要途径,能够改善供电公司的经济效益和社会效益。本文首先从配电网规划的相关理论入手,简单介绍了配电网、电力负荷预测、变电站选址定容、高压中压配电网规划以及投资估算和经济评价等方而的内容,然后根据临汾城区的总体发展规划纲要,详细的研究和分析了该地区的配电网的现状,发现了目前临汾城区配电网存在的主要问题。按照临汾地区的经济社会发展的总体趋势和电力电量的历史数据统计,预测出了规划年份(2018年)的电力负荷发展水平。然后根据电力负荷分布预测的结果,对2018年11OkV配电变电站的选址分布和主变容量进行了比较全面的优化规划。并提出临汾地区的配电网中变电站和中压(10kV)配电网的规划结果,对配电网规划结果进行了综合的和全面的评价,统计出年度配电网规划结果的总投资估算和综合效益分析。最后对本次配电规划进行全面的总结,得出相关结论。更多还原

【Abstract】 In the electric power network, power distribution network and power users of contact most closely, is one of the important Bridges connecting the power supply and power load, the power user power supply reliability, stability and power quality has a direct impact.Parts with the sustainable development of economy in our country, revealed the phenomenon of urban distribution network construction the serious lag, power supply and power load development too fast. In this paper, starting from the present situation of power distribution system planning, distribution system planning strategy for the actual research.This paper follows the basic theory of project management, discusses the application of modern project management theory in the strategic planning of the proposed method, according to the main process how to do strategic planning of project management, planning, implementation, control start, finishing, the five process groups of project management, scientific and reasonable distribution network planning can not only save a lot of manpower material resources for power supply company, but also can improve the ability of urban power supply, meet the demand of electricity growth; It can accelerate the reform of distribution network construction, expanding distribution network coverage, meeting the demand, and gradually improving power quality, guide medium and long-term construction and retrofit of urban power distribution network,in order to ensure that the urban distribution network and the urban social and economic development and the coordinated development of power grid. Is necessary to raise the capacity of power supply reliability and power supply security conditions. Optimize the distribution network structure, moderately improve the distribution network planning and construction standards, improve the city’s important users of the power supply, enhance the capacity of disaster prevention and disaster reduction.Improve equipment level, so as to improve the reliability, in order to make sure to the society and residents of high quality, reliable power supply. Through transforming perfect network structure, to speed up the update travel-weary equipment, reduce network losses, improving operational efficiency, improve the efficiency of the electric power enterprise’s input and output.In this paper,first of all, from the related theory of distribution network planning, it simply introduces the distribution network, power load forecasting, substation site selection constant volume, high and medium voltage distribution network planning, the content of the investment estimation and economic evaluation. According to the overall development of linfen city planning, detailed research and analysis the present situation of distribution network in the region, found that the current main problems of linfen city distribution system. According to the overall trend of linfen region’s economic and social development and the historical data of electricity, to predict the planning year (2018) level of development of power load. Then according to the results of the prediction of power load distribution on2018,110kv power distribution substation site selection of distribution and main transformer capacity for optimal planning in an all-round way.On this basis, put forward the linfen region in the distribution system of substation and medium voltage distribution network (10kv) planning results, and the result of the power distribution system planning for the integrated and comprehensive evaluation and the statistics annual the total investment estimation of distribution network planning results and comprehensive benefit analysis. In the end, it can conduct a comprehensive summary to the distribution plan.更多还原
