【摘要】：在供电企业的线损管理中,管理不善导致的电能损失在整个线损管理中所占比重较大,因此,本文将管理线损作为影响线损的重要因素之一。10kV以上高电压等级不直接与用户接触、设备先进,在企业线损工作中易于管理,而10kV及以下低电压等级与广大用户接触密切,终端设备易被操作,线损管理涉及面较大,线损管理中薄弱环节多。通过对线损率这一主要经济技术指标观测,可以全面提高电力网规划设计,优化生产运行和完善经营管理水平。降低线损率,意味着减少了电能传输能耗,提高了电力供应能力,从而增加供电企业经济效益。因此,研究配电网线损计算方法并以此为依据提出有效的降低管理线损的措施有很重要的理论与实际意义。本文拟结合国内外供电企业管理的现状,就供电企业如何开发10kV及以下线损管理系统,加强企业管理,提高企业经济效益进行深入探讨。主要内容为:(1)通过对国内线损管理的现状及线损管理系统的不足,提出本文研究的意义所在;(2)阐述了进行配电网线损计算的意义和线损的基本概念,在理论研究方面,通过对几种常用配电网线损计算方法的分析比较,主要采用改进等值电阻法进行配电网线损计算;(3)通过对供电企业线损管理现状调查,根据理论计算、分析的电能损失分布规律,发现管理上的问题,抓住降损工作的重点,制定细则,以降低配电网电能损耗、加强电网的经济运行。使企业线损管理工作更加精细化,实时显示线损指标,及时提出降损措施方案,解决用电企业后顾之忧,提高供电企业的经济效益。
[Abstract]:In the line loss management of power supply enterprises, the loss of electric energy caused by poor management accounts for a large proportion in the whole line loss management. In this paper, the line loss management is regarded as one of the important factors affecting the line loss. The high voltage grade above .10kV is not directly in contact with the user, the equipment is advanced, and it is easy to manage in the line loss work of the enterprise, while the low voltage grade of 10kV and below is in close contact with the vast number of users. Terminal equipment is easy to operate, line loss management involves a large area, and there are many weak links in line loss management. Through observation of line loss rate, which is the main economic and technical index, the planning and design of power network can be improved in an all-round way. Optimizing production operation and improving management level, reducing line loss rate means reducing energy consumption of electric power transmission, improving power supply capacity, thus increasing economic benefits of power supply enterprises. It is of great theoretical and practical significance to study the calculation method of line loss of distribution network and put forward effective measures to reduce the line loss of management. This paper discusses how to develop the line loss management system of 10 kV and below, strengthen the management of the enterprise, and improve the economic benefit of the enterprise. The main content is the current situation of the line loss management in China and the deficiency of the line loss management system. The significance of this study is put forward in this paper. (2) the significance of line loss calculation and the basic concept of line loss are expounded. In the theoretical research, through the analysis and comparison of several commonly used distribution network line loss calculation methods, Based on the investigation of the current situation of line loss management in power supply enterprises, according to the theoretical calculation and analysis of the distribution law of power loss, the problems in management are found, and the key points of reducing losses are grasped. Make detailed rules to reduce electric energy loss of distribution network, strengthen economic operation of power network, make line loss management of enterprise more refined, display line loss index in real time, put forward the plan of reducing loss in time, solve the worry of electric power enterprise. Improve the economic benefits of power supply enterprises.
