摘要： System, methods, and computer-readable storage media that may be used to detect excitation faults for electrical devices, such as generators and/or condensers, connected in a parallel configuration are provided. A method includes determining a change in a terminal voltage of one of the electrical devices with respect to a steady state terminal voltage. The method further includes determining a change in a reactive power of the electrical device with respect to a steady state reactive power. The method further includes determining whether an excitation fault condition exists based on the determined changes in terminal voltage and reactive power.
