The efficient speed control of three phase induction motor is one of the important constraints of
the modern world. Induction machines are being used in most of the industries and are
considered as the back bone of any industry. The efficient and precise control of induction motor
is the most desired element in implementation of process control in any industry. The motor
working mechanism should be made capable of bearing the unfavorable power system
situations. Unfortunately, the gains made with Variable Frequency Drives are often at the
expense of power quality. So controlling and doing real time monitoring can serve the best
solution in this regard. So we are making an energy saving variable frequency drive along with
the monitoring of different electrical parameters. Additionally, using World Wide Web any one
can access power quality monitoring data of the motor via the Internet. A three phase inverter is
made which is capable of running on conventional energy sources as well as on renewable
resources. We are controlling the output of three phase inverter by implementing one of the best
Pulse Width Modulation algorithm known as Space Vector Pulse Width Modulation by using
myRIO FGPA along with graphical interface of the LabVIEW for motor control process. We have
implemented the closed loop motor control of induction motor by adjusting the motor operating
voltages and frequency according to the given reference speed. This is basically a V/f speed
control of motor. The real time power quality monitoring enables us to continuously observe
different parameters such as voltage and current waveforms, torque, speed, harmonics etc. On
the basis of these factors we can improve the response of the induction motor. The real time
monitoring and accessing via internet helps to operate Variable Frequency Drives efficiently
