Abstract
This project presents a method of real time power factor improvement with the help of PLC and monochrome human machine interface. In this system PIC microcontroller is collecting the data from the components interfaced and displaying the results on monochrome HMI. PIC microcontroller will also get signal from PLC and showing the further calculations on monochrome HMI. Power factor has been improved by adding capacitors in the load (industrial Fan). Temperature sensor is giving signals showing the temperature of the atmosphere. Potential and current transformers are used to determine the values of current and voltage of the load and they are also interfaced with PIC microcontroller. All these values are also being shown on HMI with a constant clock.
