“…Nevertheless, those simulators are simplified in aspect of the wind model, which is an important factor in wind energy. Combining the achievements of previous researches, a scaled-down emulator operated on a programmable wind speed model, showing the approximate dynamic characteristics in Sajadi et al, 9 which can conduct various tests by adopting different control strategies.…”

Wind energy has become one of the most promising renewable energy in recent decades. However, severe rotor oscillations arose by the wind shear and tower shadow effects were not only harmful to the power quality but also threatening to the stability of the energy system. Meanwhile, it is difficult to simulate the effects under the local condition. Therefore, it is indispensable to develop an immersion environment for the wind energy conversion. To cover these requirements, a novel approach to simulate the process of the wind energy generation with wind shear and tower shadow effects is presented. In particular, the replication method is applicable to both fixed and variable speed turbines, for the rotor oscillations synchronizing with the rotations at a constant angle. The equivalent wind speed of the effects contributes to the aerodynamics model as nonstationary time series. For stationary processing the nonstationary signals in the time domain, the analysis of computer order tracking is imported to solve the spectral leakage in the fast Fourier transform spectrum. Finally, based on this method, an immersion environment is realized through two coupled induction motors in an electric closure test bed. Experimental results demonstrate that the proposed replication method is effective and accurate in terms of both static and dynamic performances.

This paper presents a module approach for lab-scale wind power systems (WPS). The system is designed into functional modules. These modules can be used independently or in other projects. It is also convenient to handle and set up them on a small table in classrooms and labs. Hence, they are very useful for training and research. In addition, operation on both aerodynamic side and generator side is developed in this research. Many papers on wind system simulators focus only on aerodynamic system with pitch angle control or generator system with optimal control. Thus, the operation of WPS in 2 regions, which requires coordination of aerodynamic and generator sides, is not explained and demonstrated in previous study. Many case studies are conducted to demonstrate the capability of the module-based WPS. The system is capable of speed control, optimal power control and pitch angle control. As illustrated in experimental results, these control strategies can efficiently cooperate under operation in 2 regions of WPS.
