A NOVEL ON LINE ADAPTIVE BASED STABILIZER FOR DYNAMIC STABILITY IMPROVEMENT WITH UPFC

In this paper, a linearized model of a power system installed with a UPFC has been presented UPFC has four control loops that, by adding an extra signal to one of them, increases dynamic stability and load angle oscillations are damped. To increase stability a novel online adaptive controllers, has been used analytically to identify power system parameters. Suitable operation of adaptive controllers to decrease rotor speed oscillations against input mechanical torque disturbances is confirmed by the simulation results.
