Abstract
This paper present the project designed to correcting power factor for medical industries in Malaysia automatically. Which with hope to make the cost and energy usage efficient, because the energy source are depleting due to increase in population. Power factor is the ratio of real power and apparent power. This definition is mathematically represented as kW/kVA where kW is active power and kVA is apparent power (active + reactive). Reactive power is the non-working power generated by the magnetic and inductive load to generate magnetic flux. The increase in reactive power increase the apparent power so the power factor will decrease. Low pF will cause the industry to meet high demand thus making it less efficient. The main aim of this project is to increasing the current power factor of medical industries from 0.85 to 0.90. Power factor compensation contribute to reduction in current-dependent losses and increase energy efficiency while expanding the reliability of planning for future energy network. As technology develops, the gradual cost and efficiency penalty should reduce. Therefore, automatic power factor compensation device should become cost-effective and smaller device over time. That is the reason this project is using programmable device as it is a miniature architecture device.
Highlights
Electrical power has been proven to be one of the most important resource in Malaysia and due to its high demand and widely used, it has become a very expensive resource
The demand of commercial and industrial customers varies greatly throughout the day and for them the maximum demand plays an important role in their overall electricity bills. They need to ensure that their max demand is low as possible for their substantial savings. This is the main purpose of this project where it is to overcome the unwanted problem, power factor need to be improved by installing Automatic Power Factor Compensation
These capacitors may supply part, or all of the reactive power required by the plant
Summary
Electrical power has been proven to be one of the most important resource in Malaysia and due to its high demand and widely used, it has become a very expensive resource. The demand of commercial and industrial customers varies greatly throughout the day and for them (the industrial consumers) the maximum demand plays an important role in their overall electricity bills They need to ensure that their max demand is low as possible for their substantial savings. According to Sandesh, Singh and Phulambrikar (2012), power factor improvement leads to a huge drop of apparent power drawn from the ac source which in turn protects energy and minimizes the transmission losses This project will make the consumers see the effect of high and low power system in their consumption of energy. When the power factor is very low, the may be able to see the effect and reach out to make the operation system change as needed They can increase the power factor by using the automatic power factor compensation which use capacitor and microcontroller as the main components. On the other hand, the energy sources are depleting due to increase in population
