The proliferation of gas turbines in power systems increases the scope for taking advantage of mechanical torque control for improved network damping This paper describes a phase compensated governor for a gas turbine and explores its potential contributions to system damping in a multimachine context It is shown that the inclusion of phase compensation in the governor control loop is capable of achieving dynamic stability for the system without the need of a power system stabilizer (PSS) in the generator excitation control loop and without adversely influencing terminal voltage control In addition, it is demonstrated that a phase compensated governor (PCC) is also capable of significantly improving transient stability and by complementing the effectiveness of a conventional PSS, enables a superior overall contribution to network damping (C) 2009 Elsevier B V All rights reserved.
