摘　　要：电力系统继电保护技术是以信息技术的发展为基础的,随着网络通信技术与自动控制技术的发展,数字化变电站逐渐取代了旧式变电站,使继电保护向智能化、数字化的方向发展。继电保护作为变电站甚至电力系统的第一道防线,直接关系到变电站供电的安全性、可靠性和灵活性。所以,本文通过对一种在数字化变电站中应用到的一种新型继电保护技术的研究,分析在电力系统智能时代,如何更为安全、更为有效的实现继电保护。Power system protection technology is based on development of information technology- based, as the network communication technology and automatic control technology, digital substation gradually replaced the old substation, the relay to the intelligent, digital direction development. Even as a substation relay protection of power systems first line of defense, is directly related to the substation supply security, reliability and flexibility. Therefore, the paper through in a digital substation relay protection is applied to a new technology research, analysis era of intelligent power system, how to safer, more efficient implementation relay.
