Analysis of Low Voltage Distribution Network and the Development Direction of Intelligent Distribution Transformer Terminal

摘要: 本文通过对低压配电网的现况进行分析，指出低压配电网运行管控手段匮乏，主要体现在智能电能表无后备电源且通信能力差、现有用电采集系统通信架构通信速率慢且可靠性差、采集终端的扩展性差等方面，已不能满足因设备规模的扩大、客户对服务高要求的管理需求。最后，结合能源互联网发展趋势，指出未来低压配电网将朝着低成本建设运营、快速需求响应、灵活业务扩展方向发展，按照国家电网最新要求，制定“云、网、端”顶层架构设计，着重攻克新一代配电自动化系统架构、低压配电物联网技术架构、配电自动化主站、智能配变终端等关键技术。

Abstract: This paper analyzes the current situation of the low-voltage distribution network and points out that the operation control means of the low-voltage distribution network are scarce. It is mainly reflected in the fact that the smart meters have no backup supply and poor communication capa-bilities, the communication rate of communication architecture in the existing electricity information acquisition system is slow and the reliability is poor, and the extensibility of the acquisition terminal is not good. These have not met the requirements for high management needs as equipment expands and customers pursue high service. Finally, in combination with the development trend of the Energy Internet, it is pointed out that the low-voltage distribution network will be developed in the direction of low-cost construction, rapid demand response, and flexible service expansion in the future. In accordance with the latest requirements of the state grid, the top-level architecture design of the “cloud, network, and terminal” will be formulated. We will capture key technologies such as a new generation of distribution automation system architecture, low-voltage distribution network technology architecture, distribution automation master station, and intelligent distribution transformer terminal.
