配电自动化实施的主要目的之一就是降低线损、提高配电网运行的经济性。配电网的理论线损主要包括配电线路中导线的电能损耗、配电变压器的铜损和铁损及其它(如电容器)损耗。在配电网的总电能损耗中,变压器的电能损耗占绝大部分。由于配电变压器等数量庞大,是城市配网损耗的主要组成部分,因此开展配电变压器经济性运行是实现电力系统经济性运行的重要环节,是降低供电成本的重要手段,也是一项非常紧迫的任务。实施配电自动化的根本目的是为了改进供电质量,减少停电时间,提高供电可靠性,降低运行费用,为用户提供高质量的服务。
One of the main purposes of the distribution automation implementation is to reduce the line loss and improve the economy of the distribution network. The theoretical line losses in distribution networks mainly include the power loss of the wires in distribution lines, the copper loss and iron loss of distribution transformers and other losses (such as capacitors). The total power loss in the distribution network, the transformer power loss accounted for the vast majority. Due to the large number of distribution transformers and so forth, it is a major component of urban distribution network losses. Therefore, carrying out economic operation of distribution transformers is an important part of realizing economical operation of power systems, an important means of reducing power supply costs, and a very urgent The task. The fundamental purpose of the implementation of distribution automation is to improve the quality of power supply, reduce power outages, improve power supply reliability, reduce operating costs, to provide users with high quality services.
