traveling wave relay testing

For many years, developers have investigated the possible use of traveling wave data for protective relaying applications.  Now the first commercial devices using traveling wave based algorithms have been released.  These new devices use sampling in the range of 1 MHz to very accurately measure the timing of reflections caused by faults. This creates a challenge for closed-loop testing of these relays with a real time simulator.  In order to test the traveling wave based relay algorithms, the simulator must operate with a timestep in the microsecond range, whereas previously protective relays were tested using timesteps in the 50 microsecond range.

Join us at WPRC where we will be demonstrating NovaCor, which has the processing power to provide a flexible, high fidelity modeling capability well-suited to testing traveling wave based relays.  The raw processing power of NovaCor helps to facilitate simulation timesteps in the microsecond range.

Learn about our GTFPGA MMC models capable of modelling up to 1024 SM per valve with half, full and mixed topology. We will be demoing the HVDC point to point and DC grid systems developed by CIGRE working groups.  See NovaCor’s ability to model large DC grids on a single NovaCor chassis!

Also learn about GPES, our new general power electronic solver that’s runs on the GTFPGA unit. GPES provides a highly flexible platform to model custom converter topologies. Compared to our small time step environment, GPES will support more nodes, more switches, and more branches with a reduced time step size!

IEC 61850 Global

Real time closed-loop testing is the most thorough test method for relay engineers and has become an integral part of the daily testing tools. This closed-loop testing provides a method of not only evaluating the performance of the protection equipment, but also evaluating the response of the power system network to the operation or mis-operation of that protection device. To achieve this, a simulator that emulates various conditions of the physical power system would be required. Then the system voltages, currents, and the breaker status would need to be send from the simulator to the protection device, and also the trip, reclose signals from the device under test need to be fed back to the simulated system. The data exchange can be well handled by the IEC 61850 Sample Values, GOOSE messages and through MMS communications.

The RTDS Simulator’s IEC 61850 communication capability is provided by the GTNETx2 card and the GTFPGA-SV board. A closed-loop relay testing will be demonstrated using IEC 61850 at the RTDS booth. Some new developments, including new models for supporting IEC 61850 Edition 2 will be presented as well. A presentation on integrated testing for IEC 61850 compatible IEDs in a simulated smart automation system is scheduled in the morning session of Day 2 program.
