Abstract

This paper gives information of three phase induction motor operates indirect field oriented control which rotor flux DQ model is presented. In this paper various faults are analyzed such as voltage, current, speed and torque, stat or flux for both open loop and closed loop control and experimentally explained. To develop the model, faults are first identified, and faults are injected then, a simulation model of the setup is developed. Faults are injected into the model in sequential levels and the system performance is analyzed after each and every fault. Then experimentally phase to phase fault and single phase faults are also studied. Here IFOC with rotor flux DQ model was simulated using MATLAB/SIMULINK software and verified experimentally. Also the wave forms of voltage, current, speed, torque, Q-axis and D-axis stat or flux are obtained. The above faults are analyzed and rectified which results in the increase of system performance.

Keywords: Fault Impact Assessment, Induction Motor Drive, Rotor Flux DQ Axis Model, Openloop and Closedloop IFOC
