关于智能变电站继电保护设施,是现代电力系统构建的基本要素,基于灵活性、安全性、准确性等原则之上,按照具体配备可分成过程层与变电站层。前者适用于一次性设备的单独取样,可脱离基站的同步取样,借助同步数字系统和乒乓算法实现整体取样的同步,即采取分布配置保护各部件,通过单独传输媒介实现信息的传输;后者则针对变电站部件集中后备保护,采取的是在线实时整定技术。
About intelligent substation relay protection facilities, is the basic elements of modern power system construction, based on the principles of flexibility, safety, accuracy, according to the specific equipment can be divided into process and substation layers. The former is suitable for single-time sampling of equipment, can be separated from the base station of the synchronous sampling, synchronized digital system and ping-pong algorithm to achieve the overall sampling of the synchronization, that is, distribution and protection of the various components, through a separate transmission medium to achieve the transmission of information; the latter For substation components centralized backup protection, take online real-time tuning technology.
