Development of a real time wind turbine emulator based on RTDS using advanced perturbation methods

This paper presents the development of a fixed speed wind turbine emulator using the Real Time Digital Simulator (RTDS). The wind turbine emulator consists of a wind turbine modeled in an RSCAD software environment. The software model for the wind turbine generates appropriate torque signals based on wind speed profiles using auto-regressive moving average and perturbation methods. These torque signals were fed to a servo motor emulating the wind turbine and were connected to an induction machine that emulated the generator. The response of the emulator shows that it closely matches the performance of the software model under various wind speed profiles. Thus, it can be used as an effective research and experimental tool in several wind energy based renewable energy projects.
