Management System Of Relay Protection And Fault Information Based On Telemechanical System

The protective relay is the important equipment which ensures the safe operation of the power system, it develops with greater change, carrying out the transition from the original electromagnetic relay to the micro computer relay. The electromagnetic relay and micro computer relay coexist in the power system at present, among them also including the transistor relay, integrated circuit relay, etc. The variety of the equipment has brought enormous work to operator, and made the management even more complicatedness. Meanwhile, the high dependability of the relay protection is required, and the relay protection is dispersed. These make the control over relay protection very complicated. So, for strengthening the management of the work of relay protection, improve the management level of protection work, meet the demand of information age, realize the information and networked of the management, it is necessary to develop a set of information management system of relay protection. Thesis centers on relay protection modeling and development of the management information system, makes detailed demand analyses to questions existing in the real work, and develops the systems soft ware with practical valueThe main content of the thesis has:1. Have described the necessity and important meaning of developing the administrative system of relay protection. Have analyzed the question existing in the relay protection management, has designed the systematic structure and planned the function module.2. Have described the merger question of management information system and dispatch automated system. In order to improve the automatic level of system, the matching problem of management information system and SCADA system has been researched deeply.3. Considered the actual demand, the management information system of relay protection has been developed, and put into the practical application.
