Power System Simulator- a teaching tool protection integration

Protection schemes are mandatory for the safety and reliability of power systems operations. A Power System Simulator has been built as a teaching tool in order to provide a clear picture of the system, including generation, transmission and distribution, for the Electrical Engineering undergraduate. The simulator is based on using real 11kV vacuum circuit breakers as the base of operations and is a voltage scaled down version of a power system. The implementation of a distribution system at 400V and the improvements to the controllability of the motor generator set which models generation in one area of the simulator are discussed. A PSCAD (Power System Computer Aided Design) simulation is presented to validate the physical model built. The Implementation and co-ordination of protection schemes for an interconnected network is a challenging task. Thus the paper discusses the implementation of a bus bar protection scheme and the integration of protection aspects with the overall system.
