Thread Subject: wound rotor induction generator modelling

Dear All,
i am working a on project that requires me to model a wound rotor induction generator on Matlab Simulink ? software. it is required to use Simulink ? software to model the motor/generator and its operation using a 3-phase PWM inverter. i have difficulty in doing this since i do not have much experience using this software. i have difficulty in deciding some inputs to various block parameters. i am supplying a dc voltage to a inveter that feeds the rotor windings and im using a asynchronous machine (SI units).i have the electrical parameters for the machine but im not sure of the other default parameters that are also available, when im simulation im not sure whether it is in motor mode or generator model, the mechanical input im using is: speed
