Mixed-signal power system emulator extension to solve unbalanced fault transient stability analysis

This paper presents the extension of a platform originally devoted to symmetrical transient stability analysis, into the domain of unbalanced faults. The aim of this solver is to increase the speed of dynamic stability assessment for power systems. It is based on an analog representation of the grid alongside dedicated digital resources for the simulation of the models of power network components. Using the symmetrical components theory, this platform can be adapted to handle unsymmetrical disturbances, such as single-phase-to-ground faults, and the tripping of single-phase circuit breakers.
