PROJECT DESCRIPTION

The project is designed to minimize  penalty for industrial units  using automatic power factor correction unit.

In this proposed system, two zero crossing detectors are used for detecting  zero crossing of voltage and current. The time lag between the zero-voltage pulse and zero-current pulse is duly generated by suitable operational amplifier circuits in comparator mode is fed to two interrupt pins of a microcontroller. It displays time lag between the current and voltage on an LCD.

The program takes over to actuate appropriate number of relays from its output to bring shunt capacitors into load circuit to get the power factor till it reaches near unity. The capacitor bank and relays are interfaced to the microcontroller using a relay driver. The microcontroller used in this project belongs to 8051 family.

Furthermore, the project can be enhanced by using thyristor control switches instead of relay control to avoid contact pitting often encountered by switching of capacitors due to high in rush current.

PROJECT RESOURCES
Q & A
Q:  Which microcontroller is used in this project?
A:  The microcontroller used in this project is a 40 pin IC from 8051 family.
Q:  Which inductive load is used in this project?
A:  A 40 W tube light choke is used in this project.
Q:  Can I replace choke by induction motor?
A:  Yes, the choke can be replaced by induction motor.
Q:  Why is the lamp used in series with the inductor?
A:  A lamp is used in series with the inductor, because a standard 40 watt tube light choke cannot be directly connected to mains.

Automatic power factor correction i searched this keyword in google
You have maintaining different types of kits so we liked most about the readymade kit
Everything is fine
Okay i’ll go through thank you

I searched the project title automatic power factor compensation in google.
you people are providing programming, abstarct,and documents thats why we purchased.
i alone purchased
Yes will suggest my friends and also siblings

I came to know about edgefx through google. I was searching for my academic projects in google then, i got to know about edgefx.
I have decided to purchase project from edgefx because there is no other website like this which is supporting students. And, my project is similar to edgefx project. So, i have decided to purchase project from edgefx. I like kit presentation.
the kit was delivered in time with right components.
the support team has helped me in purchasing the project.
i want to give reference to my juniors.
