Abstract
Unique systems, methods, techniques and apparatuses of a substation phasor data concentrator (ssPDC) is disclosed herein. One exemplary embodiment is a method for operating an electrical substation including a merging unit (MU), a phasor measurement unit (PMU), and a substation phasor data concentrator (ssPDC). The method includes receiving, with the MU and the PMU, input information corresponding to a set of electrical characteristics of the electrical substation; measuring, with the MU, the input information; measuring, with the PMU, the input information; a and estimating, with the ssPDC, electrical characteristics of the electrical substation using the received false measurement and the one of the MU measurement and the PMU measurement, determining in substantially real time the false measurement does not correspond to the set of electrical characteristics using the estimated electric characteristics, and replacing the false measurement with the received the one of the MU measurement and the PMU measurement.
