In this paper, two control schemes such as direct control scheme (DCS) and vector control scheme (VCS) are presented for permanent magnet synchronous generator (PMSG) based adjustable speed wind turbine (WT) system. In DCS, all parameters are obtained in the stator reference frame to invalidate the need of continuous position of rotor. Furthermore, it is analyzed that the DCS acquires numerous advantages over traditional indirect VCS such as torque, flux control lacking any rotor location. It is lesser parameters dependence and sensor less operation. In both the techniques, the DCS can operate underneath fixed and dynamic wind velocity conditions. Both of these control schemes are implemented in MATLAB/Simulink software, and the obtained characteristics are shown which results effective and satisfactory performance. |
