Abstract :
Synchronous generators in a power system exhibit rotor oscillations around their nominal steady state rotational speed. Conventional power system stabilizers have limited damping capability of inter-area mode of oscillations, when the frequencies lie beyond their bandwidth. Variable speed wind generators, with fast real and reactive power regulation capabilities, are being integrated into power systems. This paper investigates different power system stabilizer designs and damping strategies suitable for variable speed wind farm applications. Based on damping applications with flexible AC transmission system (FACTS) and HVDC, the paper investigates how power system stabilizer functions can be integrated into the wind farm controller and their effectiveness. Testing scenarios include different locations of wind farm.
