In this paper electric power generation from wind is achieved by directly coupling wind turbine to a squirrel cage induction generator without gear box. A matrix converter (MC) is used as an interface between the grid and the generator for direct to grid power injection. For the control of the induction generator voltage and frequency, a cosinusoidal modulation technique for switching of matrix converter devices has been applied. Present work relates to improvement of quality of the grid side current by having a composite structure of multiple matrix converter controlled induction generators in parallel. These aspects enhance the possibility of application of proposed matrix converter control in wind farms having multiple wind turbines.
