Abstract- This paper explores the various protections for Induction Motor using Fuzzy Logic controller. Induction motor is the most widely used motor in the industry due to its simple and rugged construction. It requires least maintenance as compare to the other electrical motors Mainly the induction motor needs protection from the variation of the input supply. For the proposed protections three inputs are applied to the Fuzzy Logic Controller to attain the objective. The inputs provided to the FIS editor are Current, voltage and Time. Current sensor is employed to sense a single phasing, any undesirable increase in current and time is calculated when this overcurrent appears and voltage sensors are provided to the controller for voltage protections. main objective is to limit the current and turn the motor OFF whenever necessary during undesirable changes in voltage and current. For an unsustainable high current for a longer time or during single phasing or during under/over voltage condition the motor is turned OFF.
Index Terms—Fuzzy Logiccontroller, Overcurrent Protection, under/over voltage protection, Current Limit, motor off, single phasing condition.
I. INTRODUCTION
Induction motor is the most widely used motor in the industry due to its simple and rugged construction. It requires least maintenance as compare to the other electrical motors. Induction motor speed control is now a day’s easier and versatile due to the advancement in the field of power electronics and hence is easy to replace other costly and controllable motors. The protection of induction motor plays an important role in its long life service. Mainly the induction motor needs protection from the variation of the input supply for small motors which is in common use not only in big industry but also in small scale industries. This paper focus on the overcurrent, under voltage, overvoltage and single phasing protection of Induction Motors.
