| Abstract | ||
| This paper focuses on the design and implementation of an automatic control system based on microcontroller that enhances the load power factor (PF) in real time. The system is designed to detect the load power factor and improve it automatically. The system is composed of several elements; the main is microcontroller which compares between the measured load power factor that is received from the energy metering integrated circuit (ADE7763) and a pre-stored value “PF = 0.95”. Based on the calculated difference in power factor, the microcontroller drives the power switches (relays circuit) through an interface circuits to choose the appropriate capacitor bank that is required to improve the power factor. Furthermore, the system is able to send the system power factor data in real time to clients either by a Short Message Service (SMS) through an integrated GSM module or by the World Wide Web (internet) through an integrated Ethernet module. | ||
