Adaptive stabilization of power systems by governor-turbine control

Development and field tests of a damping controller to mitigate electromechanical oscillations on large diesel generating units

“…The installation of a damping controller via the speed regulation system may be advantageous because theoretical studies show that there is a weak coupling between this control loop and excitation system controllers in other machines of the interconnected power system [5,6]. Therefore, in this work an alternative technique is developed which allows the direct modulation of the inlet valve position on the diesel engine (prime mover), by controlling the electronic speed regulator output current, as illustrated in Fig.…”

A new coordinated fuzzy controller for exciter and governor systems of a SMIB power system

“…Controlling the prime mover via its governor can also offer adjustment of mechanical torque and active power and hence, help in damping oscillations enhancement [4][5][6][7][8][9].The idea of adding a PSS in governor turbine side (GPSS) is not new. Some solutions regarding conventional synchronous machines have been introduced in the past [5][6][7][8]. The principle of a GPSS is similar to that used in exciter stabilizer (EPSS).…”
