Asynchronous Machine :: Blocks (SimPowerSystems™ )jar:file:///D:/Program%20Files/MATLAB/R2010a/help/toolbox/physmo...1 of 122014/5/23 13:40Asynchronous MachineModel the dynamics of three-phase asynchronous machine, also known as induction machineLibraryMachinesDescriptionThe Asynchronous Machine block operates in either generator or motor mode. The mode of operation is dictated by the sign of the mechanicaltorque:If Tm is positive, the machine acts as a motor.If Tm is negative, the machine acts as a generator.The electrical part of the machine is represented by a fourth-order state-space model and the mechanical part by a second-order system. Allelectrical variables and parameters are referred to the stator. This is indicated by the prime signs in the machine equations given below. All statorand rotor quantities are in the arbitrary two-axis reference frame (dq frame). The subscripts used are defined as follows:Subscript Definitiondd axis quantityqq axis quantityrRotor quantitysStator quantitylLeakage inductancemMagnetizing inductanceElectrical SystemMechanical SystemThe Asynchronous Machine block parameters are defined as follows (all quantities are referred to the stator):slsAsynchronous Machine :: Blocks (SimPowerSystems™ )jar:file:///D:/Program%20Files/MATLAB/R2010a/help/toolbox/physmo...2 of 122014/5/23 13:40ParameterDefinition R , LStator resistance and leakage inductanceR' , L'Rotor resistance and leakage inductanceLMagnetizing inductanceL , L'Total stator and rotor inductancesV , iq axis stator voltage and currentV' , i'q axis rotor voltage and currentV , id axis stator voltage and currentV' , i'd axis rotor voltage and currentϕ , ϕStator q and d axis fluxesϕ' , ϕ'Rotor q and d axis fluxesωAngular velocity of the rotorΘRotor ang...
