Abstract: The detection of sensor fault and its isolation when DFIM is used in wind turbines gain interest so as to enhance the reliability and avail of distributed energy systems with latest unmatched growth in construction of offshore wind farms. The DFIM employed in wind warm coupled with wind turbine can be operated as a generator and motor. First we allowed to run DFIM as generator and three types of sensor fault are incurred in all three types of sensor (speed sensor, rotor current sensor, stator current sensor). The three types of fault which are incurred i) open circuit fault ii) gain fault iii) saturation fault. The whole thing is done by allowing to run DFIM as motor. 4. Performance study of DFIM is made after creating fault by collecting the waveform (which are discussed later) in MATLAB simulation environment. During the situation when sensor become out of service there is some changes in the performance of the machine, thus in this way we can analyze the behavior of a machine and allowed to help us to make certain preventive measure against the situation that may be arise out because of faulty situation. The parameter uncertainties due to changes in the operating It conditions will produce poor performance of the machine. The robust techniques to detect faults are exist but there is a need of extra modification in them. All this type of study work is done in MATLAB Simulink environment.
