This
paper presents the design steps and design results of a proportional-integral (PI) controller that
can be used to enhance the damping of the electromechanical oscillations of a doubly-fed induction generator (DFIG)-based wind turbine generator (WTG) connected to an infinite
bus. The proposed PI controller is designed based on pole-assignment method that
can render adequate damping characteristics to the studied system. A
time-domain approach based on nonlinear-system simulations subject to a three-phase short-circuit fault at the infinite bus is performed. The simulation results show that
the proposed PI controller is effective on mitigating generator oscillations and
offers
better damping characteristics to
the studied WTG under
different operating conditions. |
