【摘要】：电力配电网的电能损耗率简称线损率,是供电公司管理经营的综合性技术经济指标,也是一项体现电力系统规划设计水平的重要指标。随着国家电网公司合理规划电网建设、优化电网结构的同时,经营思路不断改革,企业制度和经营模式不断创新。现阶段,国网公司逐步推进科学的现代管理,摒弃粗放化管理,采取定量的、可操作的、可考核的科学管理方法。把不应该产生的电力损耗降到最低,使线损管理水平达到世界领先地位。这是提高国家电网企业竞争力,提升国家电网生产管理水平的核心内容之一,也是国家电网公司经营和发展的必要条件。本文首先对配网线损的基本概念进行概述,并对理论线损的常用方法进行分析,在此基础上,结合某县供电公司电网实际运行结构,收集其配电网线路结构数据和供售电量情况,进行配电网理论线损计算,对理论线损计算结果进行汇总分析;重点对典型10kV和0.4kV线路线损构成比重进行分析,通过理论计算查明电能损耗的组成和分布,找到重损线路和重损台区,进而提出解决方案和整改措施。文章最后针对某县配电网的薄弱部分,主要从技术降损措施和管理降损措施两方面进行改进,并对这些措施进行详细阐述。将采取技术措施之后的线损和线路改造之前进行对比,线损率有明显改善。针对公司运营管理现状,从组织结构、统计手段、防窃电、计量管理、用电管理这五个方面加强线损管理基础工作,促进线损工作深入开展。
[Abstract]:The power loss rate of power distribution network is referred to as linear loss rate, which is a comprehensive technical and economic index of power supply company management and management, and also an important index to reflect the level of power system planning and design. With the rational planning and optimization of the power network structure of the State Grid Company, the management ideas are constantly reformed, and the enterprise system and operation mode are innovated constantly. At present, the national network company gradually promotes the scientific modern management, abandons the extensive management, and adopts the quantitative, operable and examinable scientific management method. Minimize the power loss that should not be generated and bring the line loss management level to the world's leading position. This is one of the core contents of improving the competitiveness of the state grid enterprises and improving the production management level of the state grid, and is also a necessary condition for the operation and development of the state grid company. In this paper, the basic concept of distribution network line loss is summarized, and the common methods of theoretical line loss are analyzed. On this basis, the actual operation structure of power network of a county power supply company is combined. Collect the data of distribution network line structure and electricity supply, carry on the theoretical line loss calculation of the distribution network, collect and analyze the theoretical line loss calculation result, focus on the typical 10 kV and 0.4 kV transmission line loss proportion analysis, Through theoretical calculation, the composition and distribution of power loss are found out, and the reloss line and station area are found, and the solutions and corrective measures are put forward. Finally, aiming at the weak part of a county distribution network, the paper mainly improves the technical loss reduction measures and the management loss reduction measures, and expounds these measures in detail. The line loss after technical measures is compared with that before line modification, and the line loss rate is obviously improved. In view of the present situation of the company's operation and management, the basic work of line loss management should be strengthened from five aspects: organizational structure, statistical means, anti-theft electricity, metrological management and power management, to promote the further development of line loss work.
