Compensation of negative sequence stator flux of doubly-fed induction generator using polar voltage control-based direct torque control under unbalanced grid voltage condition
This study proposes a polar voltage control-based direct torque control method to reduce the effects of unbalanced grid voltage on doubly-fed induction generator (DFIG)-based wind turbine system. Under unbalanced grid voltage, the stator flux has a negative sequence component which leads to second h...
