REAL-TIME COMMUNICATION IN A SYNCHRONOUS STATES MONITORING SYSTEM FOR WIDE AREA POWER SYSTEMS

In recent years, great attentions are paid to real-time synchronous monitoring systems for the states of wide area power systems based on the GPS. In such systems, the real-time communication over long distance plays a very important role. Here, various solutions for real-time communication are discussed and compared, and a real-time communication system designed by the authors is expatiated on. This communication system, which mainly constitutes by the networks with certain communication delay and runs in synchronous parallel mode, is implemented and applied in actual power system, so the requirement of real-time communication can be met. In addition, in the design of this system the modularization method is adopted, so it possesses good compatibility and expandability and can be put into practical application.
