The TSAT-RTDS™ Interface (TRI), developed exclusively with Powertech Labs Inc., creates a powerful synchronized EMT-TSA co-simulation platform using the RTDS Simulator and TSAT software. TSAT, part of the DSATools™ suite of power system analysis tools, is a powerful industry-standard software used for Transient Stability Assessment (TSA) of bulk power systems. TSAT includes a rich model library, state-of-the-art solvers, useful analysis features, and a highly intuitive user interface.
HOW TRI WORKS
- Divide the network. Define the focus area to be modelled via EMT simulation on the RTDS Simulator and the external system to be modelled via TSA simulation in TSAT (supplied by Powertech Labs).
- Interface via special hardware. An FPGA interface board sits in the PCI/E slot of the PC running TSAT. This board is connected to the RTDS Simulator via optical fibre, forming a bidirectional interface.
- Synchronize and exchange.The RTDS Simulator exchanges results with TSAT at the end of each TSAT timestep.
USE CASE EXAMPLES
- Fault analysis in HVDC systems.
- Sub-synchronous resonance studies.
- DER impact studies.
- Low-frequency oscillation impact studies.
- HIL testing with large-scale system represented.
- Unbalanced fault studies.
LIMITATIONS AND COMPATIBILITY
In addition to the RTDS Simulator, TRI requires Powertech Laboratories Inc. to supply a TSAT license (runs on MS Windows 7/10/Server 2012). A Xilinx VC707 general-purpose FPGA board is also required for interfacing.
TSAT may be interfaced with RTDS Simulators containing NovaCor-, PB5-, or GPC-based hardware.
