<p>A phasor representation of an electrical entity at a geographical location in a multiple phase AC electric power system is produced by receiving a synchronization signal from a remote source, producing a sampling time signal in response to the synchronization signal and a local reference time signal, and producing samples representing an amount of the entity in respective ones of the phases in the AC power system in response to the sampling time signal and the electrical entity in respective ones of the phases in the AC power system. A transformation is performed on the samples to produce a two-axis rotating reference frame representation of the electrical entity in a two-axis rotating reference frame. For each sample, a representation of a sampling time associated with the sample is produced. The two-axis rotating reference frame representation and the representation of the sampling time comprise the phasor representation.</p> |
