Abstract :
Aiming at the power device open and close faults occurred in the inverter, GUI based simulation platform for inverter drive system under fault condition is studied primarily in this dissertation. Using the S-function block of the MATLAB, the S function of the motor is written. The SIMULINK blocks of the inverter under different power device faults condition are built by the basic blocks of MATLAB/SIMULINK toolboxes, and the simulation system of the inverter drive system is completed. Finally, using the GUI to encapsulate the inverter drive system, the simulation platform for inverter drive system under fault condition is formed. The block of the inverter drive system under different faults condition can be called freely, and the figures of the phase current, torque, rotation speed are plotted simultaneous by controlling the button in the GUI platform. By studying these waveforms, the results show that the phase current, torque and rotation speed can be used as fault characteristics to achieve inverter fault detection and diagnosis rapidly.
