电子行业的数字化技术飞速发展,工商界的许多领域都正在进行数字化革新。可以预计,随着技术的发展,每套设备、每个插座和开关甚至每盏白炽灯都将具有设置、监测以及控制功能。为了管理众多器件并且使这些器件互相通信,需要一种新型的通信模式。这种通信模式以变电站IEC 61850通信网络和系统作为标准。随着IEC 61850标准的不断推广,变电站技术也得到迅速发展。基于IEC 61850的数字化变电站逐渐得到应用。本文阐述了IEC 61850的内容和特点,分析了数字化变电站的结构,并指出数字化变电站建设是变电站未来发展的必然趋势。
Digital technology in the electronics industry is rapidly evolving, and digital innovation is under way in many areas of business. It is expected that as technology evolves, setup, monitoring and control functions will be available per set of equipment, each outlet and switch, and even for each incandescent lamp. In order to manage numerous devices and to communicate these devices with each other, a new type of communication mode is required. This communication mode is based on substation IEC 61850 communication networks and systems. With the IEC 61850 standard continues to promote, substation technology has also been rapid development. Digital substation based on IEC 61850 is gradually applied. This paper describes the content and characteristics of IEC 61850, analyzes the structure of digital substation, and points out that the construction of digital substation is the inevitable trend of future substation development.
