STUDIES OF REAL-TIME ADAPTIVE OPTIMAL EXClTATION CONTROLLER AND ADAPTIVE OPTIMAL POWER SYSTEM STABILIZER
IEEE Transactions on Energy Conversion, Vol. 7, No.3, 598 September 1992.,-0001,():
Use of an adaptive optimal control algorithm for two realtime control applications, (i) optimal excitation control of a synchronous generator (OEC) and (ii) power system stabilizer (PSS) is described in this paper. Experimental studies on a physical model of a power system show that the proposed OEC and PSS can track the controlled system by parameter identification at different operating conditions. The proposed control algorithm is based on the linear optimal control theory and a special 5th order discrete Riccati equation is solved in each sampling period. The proposed OEC and PSS can always guarantee that in closed loop the controlled system is stable based on the identified parameters. As the actual output of the controlled system and control are directly used in the controller, no observer is required. Also, the proposed OEC and PSS can track the controlled system very fast. A number of tests have been performed. All show satisfactory results.
