Tytuł: Electrical system elements aggregation for parallel computing in real-time digital simulators

Streszczenie: Above article is about the issues of constructing digital real-time simulators of electrical systems. A characteristic thing of this type of simulators is the possibility of direct cooperation with physical devices, such as regulators etc. It is expected to obtain the results of numerical computations for a given level of adequacy in a particular time. To allow perform parallel calculations, it is appropriate mathematical models of electric system have to be used. We can achieve this using decomposition of the mathematical models of electrical systems at the simulator design stage. To accelerate calculations it is recommended to use mathematical models of aggregated electrical system elements. In this article we derived the mathematical model of the aggregated linear sample of three-phase element, which is used afterwards in the simulator of linear electrical system sample. Experiment results with the use of digital platform with 6-core processor have been also covered in this paper.
