Automated System for Power Factor Correction

Efficient power usage has become essential in both industrial and domestic electrical systems, making power factor correction (PFC) highly important. This project presents a smart Arduino-based PFC system with both automatic and manual control, along with IoT monitoring capabilities. A PZEM sensor is used to measure key electrical parameters such as voltage, current, power, energy, and power factor in real time. Based on these readings, the system identifies the type of load and activates capacitor banks when an inductive load is detected to improve the power factor. A relay module is used for switching, offering a simple, reliable, and cost-effective solution. In automatic mode, the system maintains the power factor close to unity by controlling relays on its own, while in manual mode, users can adjust the system as needed. An LCD displays real-time data, and an ESP8266 WiFi module enables remote monitoring and control through a mobile application. Overall, the system enhances energy efficiency, reduces power losses, and provides an economical and flexible approach to power factor correction.This project proposes a smart and efficient approach to power factor correction using an Arduino-controlled system with IoT integration. Electrical parameters are continuously monitored using a PZEM module, enabling accurate detection of power factor and load type. Based on this analysis, capacitor banks are switched using a relay module to improve the power factor. The system operates in both automatic mode, where corrections are made without user intervention, and manual mode, where users can control the process.
