【正文】 te operation, active power, reactive power, electromagic torque, mechanical torque and speed are constants. DFIG coordinate transformation diagram Vector control strategies based on statorflux orientation ? DFIG voltage equation in a twophase synchronous rotating coordinate system: (11) DFIG system flux equation under the twophase synchronous rotating coordinate : (12) Vector control strategies based on statorflux orientation ? To reduce the system order and simplify the mathematical model, directiing daxis synchronous rotating coordinate system. ? with the following assumptions: a. Ignoring the transient process of the stator flux, that space vector Ψs is in synchronous speed rotation, keeping the amplitude constant. And the Ψs was defined in the daxis synchronous coordinates。 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)
