Project Summary

The desire for new energy sources is insatiable, yet we rarely recognize that we waste a portion of the electrical energy we use every day due to the lagging power factor in the inductive loads we use. As a result, there is a pressing need to avoid energy waste. In simple terms, power factor indicates how much of the energy supplied has been used. The power factor has a maximum value of unity. As a result, the closer the power factor number is to unity, the greater the utility of energy or the less wastage. Power factor is defined as the ratio of active to reactive power or the phase difference between voltage and current in electrical terms. Active power is utilized to do useful work, whereas reactive power is used to produce the magnetic field required by the device. The power factor of the majority of the gadgets we use is less than unity. As a result, it is necessary to get this power factor closer to unity.

Here we are presenting a prototype for automatic power factor correction using microcontroller (Arduino). Capacitor banks used for power factor correction reduce reactive power consumption, resulting in lower losses and higher electrical system efficiency. Single phase capacitor banks for home applications have been developed as a result of power saving and reactive power control concerns. The goal of this project is to design a microprocessor-based control system to improve and upgrade the operation of single phase capacitor banks. The control unit will be able to regulate the individual capacitors in the capacitor bank and will work in steps depending on the power factor variation. To measure the power factor, a current transformer and a voltage transformer are employed to sample the circuit current and voltage. This microprocessor control system's intelligent control assures even capacitor step consumption, reduces the number of switching operations, and improves power factor correction.

Project Objectives

To improve power factor which lags due to inductive load we have following project objectives.

Benefits of the Project

This automatic power factor controller makes monitoring and improving the power factor of an electrical system simple and reliable.

A system with improved power factor will provide the following advantages:

• • Reactive power decreases
  • Avoid poor voltage regulation
  • Overloading is avoided
  • Copper loss decreases
  • Transmission loss decreases
  • Improved voltage control
  • Efficiency of supply system and apparatus increases

This kind of automatic power factor controller is cost effective, so can be applied to small systems too.
