Automatic Power Factor Correction

In the present technological revolution, power is very precious, making it crucial to identify the causes of power loss and improve the stability of power systems. With industrialization leading to increased use of inductive loads, the efficiency of power systems has declined, necessitating improved power factors through suitable methods. This study introduces an automatic power factor correction device that accurately reads the power factor based on the delay between current and voltage signals from the AC mains, utilizing an internal timer for calibration. The microcontroller then calculates the compensation requirements and activates the appropriate capacitor banks. This technique can enhance stability and efficiency across various domains, including IT industries, power systems, and households. Additionally, the integration of microcontrollers reduces costs and allows for control over multiple parameters while minimizing the need for extra hardware components. However, care must be taken to prevent overcorrection, as excessive voltage and current can destabilize systems and reduce the lifespan of capacitor banks. The findings suggest that automatic power factor correction devices are highly effective for optimizing power quality and ensuring operational efficiency in electrical systems.
