Development of Supervisory Control and Forewarning System for Power Grid

Power grid supervisory control as well as the prediction of hidden dangers that may cause faults and outage are very important measures to ensure secure and stable operation of power grid, for this reason a supervisory control and forewarning system for power grid is constructed by use of remote supervisory control technique, power grid fault pattern identification, high speed diagnosis technique and power grid monitoring and evaluation system. The constructed system can carry out real-time dynamic supervisory monitoring and prediction evaluation of power grid according to instant change of power system state; implement high speed information transmission, decision making, alarming and protection operation by use of power grid forewarning system and high speed network communication technology; and realize information sharing. Here, the implementation scheme of forewarning system, the method to predict power grid state and real-time supervisory control method for power grid faults are analyzed, and the experimental and operational results are illustrated.
