Abstract
Systems and methods are described herein to detect an open-phase condition associated with an inverter-based resource for electric power generation within an electric power delivery system. An electric power delivery system may include one or more inverter-based resources that provide three phased electric power to one or more loads of an electric utility. A controller may include circuitry to measure voltage unbalances between different phases, high voltage sequences, phase voltage waveform harmonic distortions, voltage levels, and current levels to dependably detect an open-phase condition of the electric power delivery system.
