Reactive Power Control in Permanant Magnet Synchronous Wind Generator Using Matrix Convertor

The reactive power is control by using Matrix converter at variable speed permanent-magnet synchronous wind generator and improving the performance. The frequency and amplitude of induced voltage also changes due to variation of wind speed. A matrix convertor is used to overcome this problem. A generalized modulation technique concept related to singular value decomposition of the modulation matrix is used to model different modulation techniques and investigate their corresponding input reactive power capability. A new control method is proposed for the matrix converter based on this modulation technique, which uses active and reactive parts of the generator current to increase the control capability of the grid-side reactive current compared to conventional modulation methods. A new control structure is also proposed which can control the matrix converter and the grid-side maximum achievable reactive power for all wind speeds and power conditions generator reactive current is improved.
