Distributed state estimation based on the supercalibrator concept - laboratory implementation

Abstract

The supercalibrator concept was introduced based on a statistical estimation process that fits the GPS- synchronized measurements and all other available standard data into a three-phase, breaker-oriented, instrumentation inclusive model. In this approach, the asymmetries, unbalances and the instrumentation errors are taken into account in the state estimation procedure.The laboratory setup considered in this paper is the scaled down model of a three substation power system.
