IoT-Based Power Monitoring and Management System of a Distribution Substation

Remote monitoring and control of a substation is a critical issue for the power or energy management department, which is typically done manually or with the help of a costly PLC and SCADA system. With the emergence of the internet and the computational era, a smart monitoring and trustworthy controlling system over the complete sub-station is extremely desirable, which may be accomplished by implementing Internet of Things (IoT) technology. A substation contains numerous electrical components such as transformers, breakers, relays, etc. The traditional method requires a regular manual testing system with limited precision. Furthermore, substations in metropolitan settings are more difficult to physically inspect, requiring more time to complete related tasks. In this research work a monitoring system has been proposed that is low-cost, user-friendly, and works automatically to avoid labor involvement and system loss. The results of the system are displayed in many ways to ensure that the system parameters will be monitored by more than one person for safety and protection reasons. A novel feature of automatic load management system is incorporated in this project which is absent in the latest work in the literature. When load demand is increased beyond the allocated power of a particular area a priority-based load shedding is performed automatically. The project is simulated using Proteus. Besides, a small prototype has been built to monitor physical operation. The uniqueness of this system is the display of results on desktop and mobile phones simultaneously.
