   Abstract:  The paper details the design, architectural features and application of a fully digital electromagnetic transients simulator capable of real-time operation.  The custom hardware and software developed to implement the Real-Time Digital Simulator (RTDS) is described with special emphasis given to the high level graphical user interface written especially for use with the RTDS.

   Abstract:  A greater dependence on digital simulation as a study tool for the increasingly complex Nelson River HVDC system has resulted in the need for development of complex controls models.  Simulation of known system responses has been done in the past with the use of controls models which were generally representative of overall control functions, but which still required some degree of tuning to produce results in good agreement with the system responses for the specific studies.  The recent development and validation of detailed controls models for the Bipole 1 transmission facilities has produced a model in EMTDC capable of accurately representing system response for a wide range of study conditions.

   Abstract:  This paper describes the structure and performance of a real time digital simulator (RTDS) for testing relays.  The RTDS uses parallel processing architecture based on a state of the art Digital Signal Processor (DSP) to run power system simulations in real time with a time step of 50-100 microseconds.  Physical devices sich as relays, energy monitors for MOV's or Power System Stabilizers (PSS) can be fed with the appropriate signals from the RTDS and the output from the physical device can be fed back into the simulation.  Examples are given of tests on a commercial distance relay.

   Abstract:  Improved models for current transformers, potential transformers and capacitive voltage transformers for a relay software library are presented in the paper. The magnetizing characteristic in each of these transformers is based on the non-linear power curve formulation of Lucas.  the flux-current loops of the transformer core are self generated rather than predetermined or based on look up tables.  The results presented show that the models developed for the transformers behave as expected, and agree with reported field investigations.
