A COMBINED VECTOR AND DIRECT POWERCONTROL FOR DFIG-BASED WIND TURBINES
Keywords:
Vector control, combined vector, double fed induction generatorAbstract
Author has proposed, combination of two methods vector and direct power (CVDPC) is implemented, for the rotor side converter (RSC) of doubly fed induction generators (DFIG). The implemented control system is based on a direct current control by selection of appropriate voltage vectors from predefined switching table. Benefits of vector control (VC) are fast dynamic response, system is robust even there variation in machine parameter, lower mathematical calculation and easy for implementation [1]. If we compare vector control with direct power control (DPC), it offers a advantages like less harmonic distortion and lower ripple count. While carrying out this research author has done simulation based on a Matlab. If we compare with CPDVC with VC and DPC under steady state and transient conditions,
