Abstract
A method of detecting whether a stator distortion filter is connected to a generator of an electrical power system includes temporarily interrupting magnetic flux excitation of a generator of the electrical power system. The method also includes observing a sinusoidal waveform of one or more electrical feedbacks of the generator. Further, when the sinusoidal waveform persists longer than a predefined duration, the method includes determining that the passive load is connected to the generator of the electrical power system. When the sinusoidal waveform abruptly decays below a threshold in a time period less than the predefined duration, the method includes determining that the passive load is not connected to the generator of the electrical power system. Moreover, the method includes implementing a control action based on whether the passive load is connected to the generator of the electrical power system.
