A Laboratory Setup for a Substation Scaled Model

This paper presents a laboratory setup for a substation scaled model. A unique construction procedure is employed which yields a realistic scaled model of a small three substation system, along with its metering equipment. Lumped models of transmission lines are constructed that realistically represent the mutual couplings between the phases and asymmetries. Two phase shifters provide loading controllability of the scaled model as well as controlling system imbalances. The system is designed to be a research tool for a variety of activities and studies including (a) development and validation of distributed state estimators (based on the SuperCalibrator concept), (b) protective relaying and PMU testing, and (c) validation of interoperability among IEDs. The overall laboratory setup provides a multivendor environment.
