“…Its functionality was very limited. Subsequently the HSRT simulations have used an existing simulation environment, the Virtual Test Bed (VTB), a simulation environment developed by the University of South Carolina [10] to provide the user interface. The VTB is a user interface and graphics generator that has been developed to support complex simulations developed by interdisciplinary teams.…”

Real-time simulators have been used as an aid to power system design for many years. Over time, scaled-down physical models and analog computer-based simulators have given way to real-time simulators based on digital technology. Another trend has been the need for shorter and shorter frame times for these digital real-time simulators. Modern power electronic systems use highfrequency Pulse-Width Modulated (PWM) controllers. Indications are that frame times of 2 μS are needed for PWM switching frequencies of 10 KHz. As frequencies increase further it is possible that frame times of less than 1 μS may be required. In order to achieve these very short frame times, the implementation of this type of simulator requires careful selection of the methods and technologies used. The first involves thorough analysis of the integration method chosen, to ensure that it provides the performance, stability and accuracy required. Additionally, the choice of computing platform is crucial to provide the computational support to meet these very aggressive timing requirements.
