【摘要】：在一定的时间内，将某个配电网系统内部配置的元件所消耗的电能进行统计，，就是配电网线损计算。电力网的尾端是配电网，它承担着和使用者直接连接的任务，并且由于网络设备众多，系统对此有着阻抗性。电能进行转换、输送、分配的同时，也会有着很多的损耗，从经济上来看，配电网线损计算显得尤其重要。当前，我国的电网建设越来越发达，线损计算工作为很多工作的开展提供了指导，例如：配电网拓扑设计的合理性、各种措施方案实际效果比较等。整体反映电网计划、电力运行、电网经营管理的关键经济技能指标是线损率。因此，要想提升电力供应的总体水平、增加供电企业经济收益的关键方法是降低线损。本文将会通过分析当前配电网的实际状况，对配电网线损计算的理论基础进行介绍；通过系统分析电力元件消耗电能机理，对线损计算的理论方法进行介绍，并且比较存在的优缺点；为了能够为以后降低损失提供理论与实践支持，本文将会通过理论线损计算、结合当前电网实际运行的状况，运用数据来分析计算的结果。文章的最后根据配电网的特征，对降低线损提出一些技术、管理上的策略建议。本文将会对增强配电网经济运行能力有着重要的指导作用，因为本文能够为电网的规划建设提供指导方案、对增强电网经济运行水平、制定降低电网电能损耗和线损指标等提供依据。
[Abstract]:In a certain period of time, the electric energy consumed by the components of a distribution network system is counted, which is the calculation of the distribution network line loss. The end of the power network is the distribution network, which undertakes the task of connecting directly with the users. And because the network equipment is numerous, the system has the impedance to this. The electric energy carries on the transformation, the transmission, the distribution, also will have a lot of losses, from the economic point of view, the distribution network line loss calculation appears to be particularly important. The construction of power network is more and more developed in our country. The work of line loss calculation provides guidance for many work, such as the rationality of topology design of distribution network, the comparison of actual effect of various measures and so on. The key economic skill index for power network planning, power operation, and network management is line loss rate. Therefore, to improve the overall level of power supply, The key to increase the economic benefits of power supply enterprises is to reduce the line loss. This paper will introduce the theoretical basis of the distribution network line loss calculation by analyzing the actual situation of the distribution network, and systematically analyze the power consumption mechanism of power components. The theoretical method of line loss calculation is introduced, and the advantages and disadvantages are compared. In order to provide theoretical and practical support for reducing losses in the future, this paper will combine the actual operation of the power network with the theoretical line loss calculation. Finally, according to the characteristics of distribution network, some technical and management suggestions on reducing line loss are put forward. This paper will play an important guiding role in enhancing the economic operation capacity of distribution network, because this paper can provide a guiding scheme for the planning and construction of power network and enhance the economic operation level of power grid. To provide basis for reducing power loss and line loss index.
