Abstract |
|
Induction motor is widely used in the industry. It’s downtime in factory can be avoided by providing protection to it. Early detection of abnormalities in the motors will help to avoid expensive failures. Thermal protection is one of the most important features of the motor condition monitoring system. Thermal protection of induction motor using DSP TMS320F28335 is implemented in this paper. The method for thermal protection of induction motor is developed, simulated in MATLAB/Simulink and results are presented. Since it is possible to control the speed of asynchronous motor, its cooling is also varies with the speed of rotor which is considered here. This method calculates thermal capacity accumulated by the motor in terms of percentage. Motor thermal capacity is monitored continuously using motor terminal quantities. If thermal capacity reaches to 100% then trip signal is given to motor. |
