Agent technology and the latest research works on its application in power systems are summarized. The application of Agent in protection system is considered in details from different standpoints. Then a protection system based on multi agent system (MAS) is proposed. The characteristics, structure, model and decision making process of this system is elaborated. Some topics such as its frameworks, communication, reliability, and application field are discussed. Served as an example, a scheme of the backup protection using Agent technology is outlined. Through the coordination among many distributed protection agents, the process of relay tripping and fault detection can be accelerated. And the operation time can be curtailed effectively. Comparing with traditional protection system, its performance is more satisfactory.
