Arduino Based Automatic Synchronizer for Microgrids

This paper presents an Arduino based automatic synchronizer designed for microgrids, aiming to enhance the synchronization process in distributed power generation systems. The proposed system utilizes Arduino as the central control unit to monitor and synchronize multiple generators within the microgrid. Real time measurements of frequency, phase angle, and voltage deviations across the microgrid components are obtained using ZMPT101B voltage sensors, enabling accurate synchronization. The system incorporates an intelligent synchronization algorithm implemented on the Arduino controllers. To establish or break the connection between the generators and the microgrid, a three phase solidstate relay is utilized, eliminating the need for mechanical contacts and ensuring seamless synchronization. By continuously monitoring and adjusting generator parameters, the synchronizer enables smooth power transfer, minimizes disturbances and ensuring stable microgrid operation. The Arduino based automatic synchronizer offers a cost-effective and scalable solution for integrating renewable energy sources into microgrids. The utilization of Arduino microcontrollers, along with ZMPT101B voltage sensors and solid-state relay, contributes to improved synchronization precision, faster switching speed, reduced maintenance requirements, and enhanced overall system performance.
