Abstract : The tremendous increase in the use of fossil fuels and rapid depletion of natural resources are lead to the alternative sources of energy which is environment friendly are renewable energy. There has been a great interest in wind energy in recent years because it is a potential source for electricity generation with minimal environmental impacts and with no cost of fuel. The usually used wind electric conversion system (WECS) based on Doubly Fed Induction Generator (DFIG) uses slip rings and brushes. Due to depreciation of the slip rings and brushes of generator maintenance is a major issue. Also it will be very difficult to access them in the case of offshore wind farm. So, Brushless Doubly-Fed Induction Generator (BDFIG) was proposed to replace the traditional DFIG. This paper deals with mathematical modeling of BDFIG based Wind Electric Generator (WEG) with converter control. Modeling is done for 5kW WEG with the help of mathematical equations governing each component using MATLAB simulink and the results are presented.
