Power Factor Correction And Alert Using Gsm Module

DOWNLOAD ABSRACT

AIM:

Design and Development of Power Factor Correction and Alert using GSM Module.

PURPOSE:

The ratio of output power to input power decides power factor value of any load. It should be unity or near to unity. Otherwise system is in lagging mode. If unity then lagging mode. Any industry or electrical system is in leading then we can consider it has good power factor value. To find out power factor value, current is key parameter. System needs to read input current and load consumption current. Based on current, power will be calculated. This system will send SMS when leading, lagging and normal mode. The proposed project title is power factor correction and alert using GSM module with Arduino.

DESCRIPTION:

GSM module (SIM800C) interfaced with Arduino UART port. Coil type current sensor connected to Arduino analog pin. Two relays connected to Arduino digital pins. 16×2 LCD display connected to Arduino digital pins.

WORKING:

For AC bulb power factor value is unity because of resistive type and it will be load. In this project we will show normal mode, lagging mode and leading mode and send SMS. When button pressed first time then load will be ON. Here load is AC bulb and it is resistive type. Input power and output power almost same, so that power factor almost unity. When switch pressed second time then inductor will be ON in series to load. Then lot of power consumed in inductor and less power went into bulb. This means load is in lagging mode and power factor value far away from unity. When we pressed button third time then capacitor will ON in parallel to load and power will increase at load side. This condition nothing but leading and power factor value near to unity. In each and every condition SMS will send to mobile number.
