Abstract |
In this research work, an automatic power factor correction (APFC) technique is presented to improve power factor of
industrial loads to the desired value. Power factor is corrected to provide relief to utility by supplying required reactive
power demand of load locally. The improvement of power factor of industrial customer will reduce customer monthly bill
as well as will escape from financial penalty being imposed by utility owing to his low power factor. Different power
factor correction (PFC) techniques exists, however we have proposed a new scheme of PFC using PIC microcontroller
(18F452) chip. A microcontroller based algorithm is developed to measure power factor of load and examine the
similarities or differences with the set referenced value of power factor to switch in required value of capacitors to
correct the power factor of load to desired value. The developed scheme in perspective of controlling the power factor
has a main advantage of choosing the direct value of capaci
