20 Claims

1. A power system switching element anomaly detection unit comprising:

a power system switching element position estimator configured to:

receive a set of measurements and a set of control commands associated with a power system switching element;

calculate an anomaly confidence score based at least in part on the set of measurements, a classification of a calculated power system switching element position as open or closed, and the set of control commands; and

generate, using a machine learning classification model trained using features of power switching element positions in at least one of open or closed positions to classify power system switching element positions as open or closed, the classification of the calculated power system switching element position based at least in part on the set of measurements and the set of control commands; and

a comparison unit configured to:

receive the calculated power system switching element position from the power system switching element position estimator;

receive the set of measurements and the set of control commands from the power system switching element position estimator;

receive a reported power system switching element position associated with the power system switching element; and

determine a power system switching element anomaly decision based at least in part on a difference between the reported power system switching element position and the classification of the calculated power system switching element position.
