This paper describes a real-time simulator of wind turbine generator system suitable for controller design and tests. The simulated generator is a grid-connected doubly fed induction machine with back-to-back PWM voltage source vector control at the rotor. The simulator is based on RT-LAB real-time simulation platform that allows for easy model-to-real-time-tar get design from simulink models. The paper puts special emphasis on the fixed-step simulation problematic of kHz-range PWM inverter drives and the techniques used in the real-time simulator to accurately simulate those drives.
