POWER SYSTEM STABILIZATION USING SELF TUNING PRINCIPLE

Ján Murgaš

   This paper deals with the design of an efficient power system stabilizer (PSS) which optimizes the power system damping so that the complex power system is stable even under large system disturbances. A co-ordinated control of the turbine and the generator excitation has been applied. The design is based upon the self tuning principle and uses a multi-input multi-output (MIMO) controller structure. The efficiency of the designed control has been tested on a simulation model of a real power system.

Keywords: self-tuning control, power systems, MIMO controller structure
