【摘要】 能源是发展国民经济的关键，合理充分地利用和节约能源不仅可以大大降低国民生产总成本，同时对国民经济发展也具有深远的意义。电能作为当前最优秀的二次能源之一，是社会与经济发展的基础。安全和降损是电力企业的两大主题，实际配电系统中的线损是衡量和考核供电企业生产技术和经营管理水平的一项综合技术指示，也是实行经济运行，提高经济效益的重要手段和有效途径。因此，本文从所在单位实际线损分析和管理的工程需要出发，在分析和研究线损分析理论与降低线损的技术措施的基础上，结合实际配电系统进行了实际分析和研究，全部采用实际系统参数和实际数据进行研究，提出了针对该配电系统如何降低线损的技术措施和方案，并在实际工程中得到了应用，部分已经见到成效，证明了本研究成果在理论和现实中的价值。本文主要针对实际系统进行了研究，通过实际应用证明提出的分析方法和降低线损的技术措施能有效地降低网络损耗，降低供电成本，对提高实际供电企业的生产经营效益具有明显的理论和现实意义。 本文对电力系统线损的产生原因、分析方法进行了分析和研究；对于如何降低实际系统线损的技术措施以及影响线损变化的因素等进行了研究：分析了线损分析计算的相关理论，并针对作者所在单位的实际系统的线损进行了研究，与实际运行经验相对照，提出了该系统降低线损的具体措施及方法，实际应用验证了本课题思路正确性和可行性。更多还原

【Abstract】 Energy source plays an important role in the development of national economy, so exploiting energy source fully and reasonably and saving it can not only reduce the cost of national production remarkably but also benefit to the development of national economy. Electric power, as the best one in secondary energy, is the foundation of economy. For electric utilities, security and reducing line loss are the main concerns, and the line loss is an important technical index for assessing their technique and management levels, moreover, in practical operation reducing line loss is also an effective measure and approach for improving the economic benefits. Aiming at reducing line loss, firstly, this paper investigates the theory and measurements about line loss, and then proposes a scheme that is based on a practical project in author’s utility and adopted practical parameter and data. By applying it in the practical project, the validity and merit of this scheme in reducing network loss and the cost of power supply are proved.This paper discusses the origin of line loss and its analyzing method, compares the measurement for reducing line loss in practical distribution network and factors influencing the variation of line loss, and investigates the theory using for analyzing line loss. After studying a practical distribution network by applying the theoretics and comparing with the practical operation experiences, this paper proposes some particular measures and approaches for reducing the line loss of this practical distribution network. Of course, the application testifies the validity and feasibility of the scheme.更多还原
