This paper describes a laboratory setup as the scaled model of a three substation power system. The scaled model has been developed at the Power System Control and Automation Laboratory of Georgia Institute of Technology. Elaborate physical models for the power system components along with high fidelity models for signal generation and interfacing to the laboratory setup are among its unique features...
This paper presents a laboratory setup for transient testing of relays and GPS-synchronized devices. The setup relies on a unique, realistic scaled model of a small three substation system, along with its metering equipment. Lumped models of transmission lines are included that realistically represent the mutual couplings between the phases and asymmetries. Two phase shifters provide loading controllability...
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...
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...
