Project 2 - Modeling of 3 phase Induction Motor Drive

1.ans:

for Modeling 3 Phase Inverter using Simulink with a switching frequency of 10Khz using 3 phase Squirrel Cage Induction motor using V/F method open loop according to the required design parameters:

for 100 HP with V=800 V and Speed of1500 RPM,Load Torque of 10Nm with Step Time = 0.1 secs.

we have modeled the system:

the above system is simulated and results are obtained.

the above generated results are: voltage , current, stator and rotor currents and speed of the system.

2.ans: the transfer function that can be used to create model is

3.ans:

the above transfer function can be use to generate the parameters for the induction motor to modify the torque of the motor using direct control.

for the average model:

Stator Resistance of 0.5Ohm,Rotor Resistance of 0.2 Ohm, Stator and rotor Leakage Inductance of 20 mH and 10 mH, Magnetizing Inductance of 200 mH with 4 poles.

based on the given parameters the model is generated:

and results of the simulations like torque, flux,current for both rotor and stator are generated
