Abstract
This project is mainly proposed for reducing the power loss in industries by
using power factor compensation through a number of shunt capacitors.
Power factor is defined as the ratio of real power to apparent power.
So, the increase in reactive power (real power) increases the apparent power,
so the power factor also decreases. By having a low power factor , the
industry needs more energy to meet its demand, so the efficiency decreases.
In this system , we proposed the time lag between zero voltage pulse and
zero current pulse delay generated by suitable op-amp circuits in comparator
mode and fed into two interrupt pins in the microcontroller.
The microcontroller displays the power loss due to inductive load on the
LCD.
This process is continuously actuated until the power loss would be zero by
using relays which are used to bring the shunt capacitors into the load
circuit. an 8-bit microcontroller is used in this project which belongs to the
8051 family.
