The SUPPRESS research group has developed a demonstrator model for research and education on the technologies used for control and monitoring of electricity supply. For that purpose, the usual architectures of transmission and distribution substations and end consumer delivery have been replicated.
The transmission substation architecture is based on a fiber optic ring network that follows the IEC 61850 standard, including the most representative elements in its operation: a substation
central unit, several HMI terminals and devices for control, protection and measurement of electricity lines. Besides, the distribution substation uses a telecontrol device for a compact MV cell, measurement devices and protection relays, which use Modbus TCP/IP and IEC 104 for communication.
The end consumer subsystem is an electric cabinet with remotely controlled protections that is connected to different loads. Furthermore, the end consumer subsystem has a set of single-phase and three-phase smart meters, which measure consumptions and send them to a central hub that can be accessed wirelessly. These meters communicate through the PRIME protocol, using power line communication for transmission.
