The present energy needs depends on the conventional sources but,looking at the current situation of conventional energy sources are going to get exhausted within a few decades. So,the conventional sources are replaced by non-conventional energy resources. Presently wind energy is one of the most established no-Conventional energy resources. Analysis of the real wind energy conversion system before installation is essential to avoid installation problem. It is difficult to set up a real WT in the laboratory. Therefore, in the present work, the WT behaviour is emulated using a close loop separately excited DC motor. The main goal of this research is to develop a simulation model of a wind turbine emulator based on a separately excited DC motor in the Matlab/Simulink environment. Further, the test bench of wind turbine emulator is developed in the laboratory. The performance of the WTE is validated both in simulation and hardware experiment for different wind speed profiles. The setup can be used for development and testing of the real-time wind energy conversion system. WTE is use to drive a self-excited induction generator (SEIG) to generate voltage. The SEIG based wind energy generation system is most popular for standalone application and it is widely used in small and medium wind power application. The model of self-excited induction generator includes excitation capacitance, induction generator, and load model has been realised in the stationary d-q reference frame. The SEIG dynamic performances are tested under with load and no load. To analysis the performance of the purposed system, a MATLAB/ SIMULINK based simulation study was carried out. The voltage build up process in SEIG and microcontroller based controller for wind emulator are designed in laboratory environment.
