17 Claims

1. A method comprising:

triggering, by a device, a capture of a first waveform of a first asset in a power system;

creating, by the device, a first cluster of a same type of assets including the first asset in the power system and a second asset in the power system;

triggering, by the device, a capture of a second waveform of the second asset in the power system;

establishing, by the device, a first operational baseline for assets in the first cluster of assets, wherein the first operational baseline is based on the first waveform of the first asset and the second waveform of the second asset;

triggering, by a device, a capture of a third waveform of a third asset in the power system;

creating, by the device, a second cluster of a same type of assets including the third asset in the power system and a fourth asset in the power system;

triggering, by the device, a capture of a fourth waveform of the fourth asset in the power system;

establishing, by the device, a second operational baseline for assets in the second cluster of assets, wherein the second operational baseline is based on the third waveform of the third asset and the fourth waveform of the fourth asset;

comparing, by the device, first features of the first waveform to the first operational baseline;

comparing, by the device, second features of the third waveform to the second operational baseline;

determining, by the device, based on the comparison of the first features to the first operational baseline, that a first fault has occurred in the first asset;

determining, by the device, based on the comparison of the second features to the second operational baseline, that a second fault has not occurred in the third asset; and

providing, by the device, an alert that the first fault has been identified, wherein the alert initiates or facilitates a control action in the power system.
