Real-Time Simulation of Doubly Fed Induction Generatorfor Wind Turbine Applications

摘要

This paper describes a real-time simulator of wind turbine generator system suitable forrncontroller design and tests. The simulated generator is a grid-connected doubly fed induction machinernwith back-to-back PWM voltage source vector control of the rotor. The simulator is based on RT-LABrnreal-time simulation platform that allows for easy model-to-real-time-target design from Simulinkrnmodels. The paper puts special emphasis on the fixed-step simulation problematic of kHz-range PWMrninverter drives and the techniques used in the real-time simulator to accurately simulate those drives.
