SMART TRANSFORMER USING PLC AND SCADA

This paper presents a smart transformer system that integrates Programmable Logic Controllers (PLC) with Supervisory Control and Data Acquisition (SCADA) for enhanced real-time monitoring, automation, and control in power distribution networks. Traditional transformer systems face challenges such as manual monitoring, delayed fault detection, and inefficient load management, leading to reduced reliability and increased downtime. To address these issues, the proposed system continuously monitors key parameters such as voltage, current, temperature, and load using sensor data fed into a PLC system, which automatically executes predefined control actions based on the input conditions. The SCADA interface allows for remote supervision, providing operators with real-time data visualization and alerting capabilities. The integration of PLC and SCADA not only ensures improved transformer performance but also enhances the overall efficiency and reliability of the grid. Preliminary test results demonstrate the effectiveness of the system in minimizing operational downtimes and responding promptly to faults. This work lays the foundation for further improvements in smart grid infrastructure.
