Abstract

The present disclosure relates to a method and system for estimating a grid frequency or grid phase angle of an electrical power distribution system in which instantaneous voltages output by the electrical power distribution system are sampled at a plurality of discrete sample times to generate a plurality of samples; α and β values are derived from the plurality of samples using a Clarke transformation; a complex variable is generated from the derived α and β values and is applied to a generating function; the generating function is integrated for the plurality of samples; and an estimate of the grid frequency or grid phase angle is generated based on the result of the integration of the generator function.
