TUT

Laboratory demonstration of TUT consists of Real-Time Digital Simulator (RTDS) and distribution automation system of field demonstrations. The main interest is related to MV and LV network monitoring and congestion management.

RTDS is utilized to model field demonstration networks and DERs included in them. The following figure describes the laboratory demonstration. Hardware and software of distribution automation (SAU and IEDs) are connected to the real-time simulator. All IEDs are commercial devices and therefore the main interests of demonstration are Substation Automation Units (SAUs) for primary and secondary substations and their functionalities. The aim of the simulations is to test interoperability of distribution automation and functionality of secondary controllers and monitoring system. Interoperability tests will simplify the starting of field tests when most of interoperability related problems are already solved in the laboratory. Laboratory tests will also extend the field demonstrations when demo sites don’t include required conditions (e.g. congestions due to over-dimensioning of the system) or don’t have necessary resources (e.g. OLTC in secondary transformer).
