Abstract

This paper presents a comparative study of two damping controllers, i.e., the power system stabilizer (PSS) and the static condenser (STATCON) damping controller, on damping enhancement of generator oscillations occurring in a power system subject to disturbances. The developed scheme employs a proportional-integral-derivative (PID) controller for the proposed damping schemes to simultaneously improve the damping of both mechanical mode and exciter mode. The parameters of the proposed damping controllers are solved by left shifting both modes to the desired locations on the complex plane using a unified approach based on modal control theory. Frequency-domain approach based on eigenvalue analyses under different operating conditions and time-domain approach based on nonlinear model simulations under a severe disturbance condition are performed. The simulated results show that the proposed STATCON controller renders better damping performance than the PSS under a severe disturbance condition.
