【正文】 b. Ignoring the stator resistance Rs. By the previous equations(11)(12)and this equation(13): (13) (14) (16) Vector control strategies based on statorflux orientation ? The definition of the magizing current ims as follows: (15) By the previous equations(14): the stator flux orientation (16) (17) Control the amplitude of the stator voltage vector (18) Vector control strategies based on statorflux orientation ? By the previous equations(15)(17)(18), mathematical model of the DFIG in independent operation as shown below: By the mathematical model of DFIG independent operation, which can get control block diagram as shown below: Vector control strategies based on statorflux orientation DFIG in independent operationthe excitation vector control strategy diagram: decoupled control Current inner loop PI controller: based on IMC Voltage outer loop PI contorller Simulation Simulation Figure: Simulation Initial conditions and requirements: ? Each phase resistance value of the load:R= ohm ? Input constant power : Pm=30 KW ? In stable operation, the stator voltage Us maintained
