dc.description.abstractThree phase induction motors are the engines more frequently found in the industry. They are simple, durable, inexpensive and easy to maintain. They are at essentially constant speed from zero to full load. Speed is frequency dependent so that these motors cannot be easily adapted to speed control. However VFD (variable frequency electronic units) are being used increasingly to control the motor speed AC induction. Controls the frequency and voltage supplied to the engine and thus controls the engine speed and the driving system. This project is basically about designing of variable frequency drive to control the speed of 3 phase ac induction motor at variable load (motor generator set).Major task is to make the speed constant whenever load is added on motor generator set. In practical life where energy and time saving is very much important VFD is the best solution to every problem related to loading machines with different loads at a time. The mechanical load of generator having different load values is connected to our motor. Whenever the load on machine changes the speed of machine changes accordingly vfd with the help of its controller section maintains the changed speed to its previous value. It increases or decreases the speed of motor with changing load. Its main purpose is to drive the motor at constant speed no matter what is the value of load.en_US
