Power Saver System By Power Factor
Micro-controller based power saver system by power factor correction with LCD display
Industries function on inductive loads such as transformers, induction motors, ballast-type lightning which has a low power factor and draws more reactive power from the supply, this reactive power is measured as used power but its inefficient and not used by the industry, this power is useless but drawn from the supply, measured causing industries/commercial establishments to spend more on electricity bill. The use of commercial power saver by industries reduces the consumption of electric power by enhancing the power factor of inductive loads, commercial establishments which does not make use of this power saver by use of coupling capacitors, phase advancers or synchronous condensers will end up spending a huge amount on power there by increasing manufacturing cost of products and also management cost of the establishment.
The major problem which this project solves is the issue of low power factor which affects the bill of industries, it also provides capacitor banks which allows for extra inclusion of loads by auto switching through relays and relay drivers according to the rating of the load added.
Other Problems Include
• increased harmonic distortion caused by saturation of inductive loads such as transformers.
• Reduced efficiency in output of industries and commercial establishments which do not make use of these compensators/enhancers.
Aims And Objectives
The aim of this project is to design and construct a microcontroller based power saver system by power factor correction with LCD display. In this project a feasible solution for the improvement of power quality and saving of power in inductive load systems.The primary motivation for the work is based on the ability of the system to reduce industrial electricity bills and also save power/energy drawn from electricity utilities for inductive loads.
• To achieve an apparent reduction in current drawn by connecting a capacitor to an inductive load
• Opposing reactive power resulting from the correction of a correctively sized capacitor can compensate for the reactive power required by the load, this ensures that only a small amount of reactive power is drawn from the power supply.
• This system isdesigned for power factor improvement.
• Enhancement of power quality in closed loop operation.
• Reduction of voltage drop in cables.
• Extend equipment life
