电力工业是我国经济发展的基石,是国民经济的重要基础支柱之一。电力网是由配电网和输电网构成,配电网就是将电力系统中变电站低压直接或降压后向用户供电的网络,也称之为配电系统。配电网由电缆配电线路、降压变压器、架空配电线路及变电站等构成。通信系统是配电网自动化的核心技术,配电网的运行状态改变、数据的采集及配电网的优化均通过通信系统。通信系统的设计合理与否将直接影响到配电管理系统的运行成败。
The power industry is the cornerstone of China’s economic development and one of the important pillars of the national economy. Power network is composed of distribution network and transmission network, distribution network is the power system substation low voltage direct or step-down after the power supply to the user network, also known as the distribution system. Distribution network consists of cable distribution lines, step-down transformers, overhead distribution lines and substations. Communication system is the core technology of distribution network automation, distribution network operating status changes, data acquisition and distribution network optimization through the communication system. The design of communication system or not will directly affect the operation of distribution management system.
