“…DRTS represents the computation and reproduction of a phenomenon that is likely to occur if a field test is performed [4]. Prior to the development of existing fully digital real-time simulators, such as real-time digital simulators (RTDSs) [5] and OPAL-RT [6], analog and hybrid simulators [7] were used until computers achieved speeds that enabled the simulation of electromagnetic transient phenomena in real time.…”

This work reports the personal computer implementation of a real-time simulator based on the widely used Electromagnetic Transients Program, version Alternative Transients Program (EMTP-ATP) software for testing protection and control devices. The proposed simulator was implemented on a conventional PC with a GNU/Linux operative system including a real-time kernel. Using foreign models programmed in C, ATP was recompiled with the PortAudio (sound card I/O library) with tools for writing and reading the parallel port. In this way, the sound card was used as a digital-to-analog converter to generate voltage waveform outputs at each simulation time step of the ATP, and the parallel port was used for digital inputs and outputs, resulting in a real-time simulator that can interact with protection and control devices by means of hardware-in-the-loop tests. This work uses the minimum possible hardware requirements to try to implement a real-time simulator. Due to the limitation of two channels, this simulator was used mainly to demonstrate the implementation methodology concept at this stage; this concept could potentially be expanded with more powerful hardware to improve its performance. The performance of the implemented simulator was analyzed through interactions with a real intelligent electronic device (IED). Furthermore, a comparison with the results obtained by means of the well-known real-time digital simulator (RTDS) was presented and discussed.

Abstmct --The University of Florida's electric power engineering program is changing educationally to better train its students. This has come about because electric power systems are being penetrated increasingly by new technologies, such as power electronics, for the purpose of improving their energy performance and control capabilities. At times the introduction of such new technologies in the power system may cause both the utility and its customers operational problems in terms of the quality of power being delivered and its actual energy usage. These problems are addressed in this paper by an examination of the key requirements needed in a lab to assess the power quality and energy performance of devices in the power system, in both a stand alone and systems context, and by computer simulations and physical testing. The power quality area is used as an example of how the lab is used in education.
