“…The DFIG of the TBS can be operated at the same voltage, current and power levels on a per unit basis, as those of the WTS. Most of the wind turbine emulation schemes reported in literature compensate for the inertia difference between WTS and TBS by controlling the torque of the motor in TBS with a torque compensation loop [3]- [5]. This loop calculates the compensation term by differentiating the speed and hence the loop becomes highly sensitive to noise.…”

Depleting fossil fuels and concerns about global warming have forced a paradigm shift towards renewable energy resources in meeting our energy requirements. Wind energy utilization has been growing at a rapid rate fuelling research and development in high power wind turbines. To advance research and education in wind energy conversion systems, a controlled test bed is necessary that does not depend on wind availability. In this paper, a control structure is proposed to emulate high power, large inertia wind turbines using low power, small inertia machines. Majority of the existing methods for wind turbine emulation employ DC or induction motors with torque compensation loop. However, it suffers from noise and instability issues. DC motors have several disadvantages compared to induction machines in terms of cost, maintenance, speed and ruggedness, even though their control is simple. Hence, in this paper, Squirrel Cage Induction Machine (SCIM) in speed controlled mode is employed for emulation. The performance of the control structure is demonstrated through an experiment involving step change in wind velocity, where the dynamics of a high inertia wind turbine system are emulated. Simulations and experiments are conducted on a 7.5 kW Doubly Fed Induction Generator (DFIG) driven by a 5.5 kW SCIM, emulating a wind turbine.

“…Analysis of the previous research demonstrates that the induction machines are the most attractive motors used as prime-movers in WTEs due to their low cost, low maintenance requirement, and high robustness. Some of these studies used simple available power curves as WT models, which exclude some important dynamics of the WT and limit the study [23,25].…”

Wind turbines are complicated systems with different aerodynamic and electromechanical aspects. An integrated platform which includes design, simulation, and experimental evaluation of wind energy conversion systems is very helpful to design, develop, and examine the performance of different wind turbine subsystems. The previous studies exclude such a platform and this study tries to fill this gap. In this study, the blades of a 5.5 kW fixed-speed stall-regulated wind turbine are initially designed then employed in simulation and emulation. The same as the simulation setup, the utilised emulator uses AeroDyn and FAST software tools to model the aerodynamic and mechanical aspects of the turbine in a laboratory environment. The emulator is capable of reproducing the static and dynamic behaviour of the turbine in a laboratory similar to the real turbines. For simulation, the electrical parts are implemented in MATLAB/Simulink, whereas the real electrical parts are used for the emulator. The performance of the turbine with the designed blades is investigated in simulation and emulation considering a simple hub-height and turbulent wind profile, generated by TurbSim software tool based on the IEC standards. Moreover, the start-up process of the wind turbine is evaluated using the wind turbine emulator and the results are discussed.

“…In general, a wind‐turbine simulation system has two applications, namely to simulate the DC [1–7] or AC [8–11] motor of a wind turbine. Frequency converters and vector control have traditionally been used to simulate wind turbines using induction machines.…”
