摘　　要：介绍了远程在线整定继电保护定值的具体实现方法,分别从继电保护故障信息系统、调度EMS系统和直连虚拟链路不同实现方案进行阐述,并对各种方案的优缺点进行分析和对比。同时还分析了继电保护定值远程整定过程中所存在的风险,并提出了多种远程安全整定的具体解决方案。通过远程整定继电保护定值方案的应用,可以实现继电保护装置远程管理与控制,并提高装置维护管理效率,为变电站实现无人值守、调度主站实现远程管理提供技术支撑。This paper introduces the concrete implementation method of remote online setting of relay protection setting value, which is diseussed from the relay proteetion fault information system, EMS system and virtual link different schemes, and analyzes and compares the advantages and disadvantages of each scheme. It also analyzes the relay setting value risk of remote modifying process and proposes specific solutions of various remote security setting. Through the remote setting of relay protection setting program application, it can realize remote control and management of relay protection device, and improve the equipment maintenance management efficiency, thus to realize unmanned substation and the master scheduler implementation of remote management and provide the technical support.
