Calculating electric power noise distributions

Abstract

The present disclosure relates to systems and methods for calculating noise distributions in an electric power system. In one embodiment, a system to calculate a noise distribution in an electric power system may comprise a measurement subsystem to obtain a plurality of raw measurements of a parameter in the electric power system. A noise distribution determination subsystem may be configured to generate a plurality of scaled raw measurements from the plurality of raw measurements, generate a power spectrum density from the plurality of scaled raw measurements, generate a cumulative distribution from the power spectrum density, and determine a noise distribution from the power spectrum density. A protective action subsystem may monitor the parameter in the electric power system to identify a signal of interest by utilizing, at least in part, the noise distribution and generating a control action in response to the signal.
