The paper presents the results of a comparative study of the application of three difference compensators, i.e., the power system stabilizer (PSS), the regulator (RCR), for the damping enhancement of generator oscillations in a power system. In order to enhance the dampings of both mechanical mode and exciter mode in the studied system, a unified approach based on nodal control theory is proposed for the design of the PSS, the SVC, and the RCR. A proportional-integral-derivative (PID) type controller using generator speed deviation as a modulated signal to generate desired damping is proposed in the study and the affected system modes, the mechanical mode and the exciter mode, can be exactly located on the prespecified locations of the complex plane by the proposed damping schemes. For demonstrating the effectiveness of the proposed PID controllers and their relative merits, frequency domain approach based on eigenvalue analysis under different operating conditions as well as time domain scheme based on nonlinear model simulations under disturbance conditions are performed.
