“…Its associated risks in PSS tuning are 1) negative synchronizing torque component and 2) faster instability of susceptible modes, leading to a much reduced gain margin. Additionally, a prerequisite [18] of phase lag to nullify overcompensation at frequency below 0.5 Hz for case C will be less than case A. Related to Fig.…”

In this paper, a technique for designing fixed parameter decentralized power system stabilizers (PSSs) for interconnected power systems is proposed. In the proposed method, local information available at each machine in the multimachine environment, is used to tune parameters of PSS. Conventional design techniques such as P-Vr frequency response approaches, and the method of residues are based on complete system information, wherein phase angles of residues are consistent with the P-Vr phase response and can be used with confidence for design purposes. It is shown that magnitude and phase information of the proposed GEP TF agrees closely with that of P-Vr TF and yields a robust stabilizer. Nonlinear simulation and eigenvalue analysis show the efficacy of the proposed stabilizer to damp out the interarea and local modes of oscillations effectively over a wide range of operating conditions. Superiority of the proposed approach over the conventional approaches is demonstrated with simulation studies on two widely used multimachine systems.Index Terms-Eigenvalue, multimachine systems, power system dynamic stability, power system stabilizer, small signal stability.

“…Auxiliary controller called power system stabilizer (PSS) provides additional damping to the synchronous generator rotor oscillations by modulating the generator excitation. PSS design has been well studied in the literature over the past few decades [1]- [11], [17], [18], [22].…”

“…Hence, excitation systems are generally equipped with Power System Stabilizers (PSS) to get an improved stability [1][2]. The PSS which is employed in a power plant should satisfy the following requirements: 1) High reliability factor, 2) Damping the oscillations of electromechanical modes, 3) The ability of functioning in various practical conditions of the system, 4) Coordination with other control and protective devices.…”

“…Using this type of PSS in thermal power plants needs a thorough investigation of its effects on the torsional oscillations as this sort of PSS although damps the rotor oscillations, on the other hand, it may lead in the instability of torsional oscillations. Thus, a good filtering has to be performed when applying them [3][4]. Terminal frequency can also be applied as the input signal to the PSS.…”

It is the purpose of this paper to investigate the design of a stabilizer via sampling the speed and voltage feedback in order to improve the oscillations of generators in Siahbisheh pumped-storage power plant in Iran. An overall PSS is utilized for all of the generators and its output is connected separately to the generators excitation systems. Moreover, a terminal voltage feedback is employed for damping oscillations. Comparing the simulation results shows a considerable improvement in the oscillations of the rotor speed, generator power, and terminal voltage. The proposed method is feasible and cost effective.

“…Uma vez que a medição direta requer a utilização de sensores em torno do elemento móvel do gerador, tal medida aparece como um dos elementos menos confiáveis na totalidade do projeto do PSS. Há relatos na literatura de PSSs que foram temporariamente desligados ou falharam devido a discrepâncias nas medidas de velocidade, resultantes, por exemplo, de falhas nas conexões elétricas ou físicas provenientes do transdutor de velocidade (KUNDUR et al, 2003).…”
