    • 1. Large-scale power systems in Real-time• 10,000 buses on-fly2. Open and scalable hardware platform• Integrated with a chassis equipped with FPGA and I/Os• Interfaced with communication protocols such as IEC61850,DNP3 (+-10ms), C37.118, OPC (+-100ms)3. Test automation platform• Perform test automation using Python scripts• Use ScopeView to record, display and analyze results• Interfaced with LabView to implement realistic control panels• Modify parameters while the simulation is runningFeatures
    • 4. Third-party connectivity• Interfaced with Simulink, SimPowerSystems and SimScape toenable users to develop their own load, control and protectionmodels• Interface with the Excel™ spreadsheet and with PTI’s PSS/e toimport the network data filesFeatures
