Sensor Fault Tolerant Control For DFIG With WECS

Abstract

Wind Energy Conversion Systems are the most striking renewable energy resources available to generate the electricity. Doubly-fed Induction Generator (DFIG) based wind turbine with variable speed is the most common wind turbine in the growing wind market. In any WECS, power flow must be maintained at all instant irrespective of any fault in the system. This paper deals with fault tolerant control (FTC) of DFIG based WECS. To have a better performance fault is detected & isolated with the help of NN. This intelligent computing technique provides better close loop performance during faulty conditions. The performance of the system under various modes of operation and FDI scheme are carried out using computer simulation. The simulation tool used is MATLAB/SIMULINK.
