Cloud Computing for High Voltage Substation Based Relay Protection

In the context of contemporary digitalization, the remote oversight and management of substation apparatus via programmable logic controllers (PLCs) and supervisory control and data acquisition (SCADA) systems has transformed into a conventional, high-expense system. Nonetheless, it is preferable to have a system that is economical, intelligent, and dependable. The real-time capabilities of the Internet of Things (IoT) significantly augment its utility; it is widely recognized as crucial for the monitoring and management of power system applications. The Internet of Things (IoT) is a networked system comprising interconnected computing devices, mechanical and digital components, items, or individuals. We assign distinct identities to each device, facilitating secure data transmission without necessitating direct human or human-computer interaction. This project aims to provide a monitoring and control system for high-voltage networks, employing cloud computing and the Internet of Things, based on protective relays and sensors. The primary advantages of this system include enhanced flexibility, the capacity to incorporate additional devices, and the ability to analyze substantial volumes of data with increased speed and precision. The design expense is significantly lower in comparison to the SCADA system. Expanding high-voltage substation networks can enhance the efficient development of the system. This system uses an ESP32 microcontroller in conjunction with sensors.
