Key point for the future challenges of the SmartGrids: The architecture of the Smart T-Station

A SmartGrid integrates mainly real-time monitoring, automated control systems, power electronics, demand response management and broadband communication. These issues are all very closely related to the secondary transformer station for their practical implementation. In fact, the sensors for monitoring and fault detection, the switches for maneuvering and network reconfiguration, the Low Voltage distribution board where all the information of the Low Voltage network may be collected, including metering data, the transformer, the communication equipments for Low Voltage and Medium Voltage....; are physically placed in the secondary transformer station. So, the Smart TStation will play a mayor role in the practical implementation of the SmartGrids. The paper describes a new architecture proposal based on functional modularity of the future Smart TStation. The proposal takes into account, not only the functional aspects needed for the SmartGrids´ future challenges, but also the real considerations for a big scale successful implementation. Its main features are easy installation and integration, no works on site, no specialized workforce for commissioning, independency on the point of the network where it is installed, scalable and open to future additional features. The proposed architecture considers every functional element, integrating the Smart TStation, including its own complete functionality. So, cubicles, transformers, capacitor banks, Low Voltage boards, power electronic devices, etc. have their own smart behavior and will be interconnected through a local bus.
