automatic power factor monitoring and control system
In the present technological revolution power is very precious. So we need to find out the causes of power loss and improve the power system performance. Due to industrialization the use of inductive load increases and hence power system losses its efficiency. So we need to improve the power factor with a suitable method. Whenever we are thinking about any programmable devices then the embedded technology comes into fore front. The embedded technology is now a days very much popular and most of the products were developed with microcontroller (ARDUINO) based embedded technology.
Automatic power factor correction device reads power factor from line voltage and line current by determining the delay in the arrival of the current signal with respect to voltage signal from the power supply with high accuracy by using an internal timer. This time values are then calibrated as phase angle and corresponding power factor. Then the microcontroller calculates the compensation requirement and accordingly switches on different capacitor banks. Automatic power factor correction techniques can be applied to the industries, power systems and also households to make them stable and due to that the system becomes stable and efficiency of the system increases. The use of microcontroller reduces the costs.
