A real-time transient stability simulation tool for large-scale power systems

Development of the Phasor tool for real-time transient stability simulation in large-scale power systems is presented in this paper. This tool can be used for performing contingency studies, testing control devices, as well as training purposes in academia and industry. The Phasor tool includes a model library that is extensible based on the user requirements. The accuracy of the tool has been evaluated in comparison to other commercial but non-real-time transient stability simulation packages, and its real-time performance has been tested on an eMEGAsim real-time simulator for large-scale power systems in the order of 10000 buses, 2500 generators, and over 4500 control devices.
