Abstract

Restoration and improvement of universal computational physical model of power system (УРМЕС-
2) by application of modern electronic components and facilities of microcontroller technology. Results. The
prerequisites of such modernization for compatibility of parameters of modern microcontroller components with the
necessary characteristics of this calculated physical model of power system are considered. It has been shown that
you do not even need to use specific software to achieve this. It is enough to use ready-made structural units, and
their programs of operation far exceed the needs for restoration and improvement of the installation. As an example,
an electrical circuit of a basic three-phase AC reference generator 200 Hz with the implementation of subsequent
voltage symmetry and power amplification. Generator design is developed. It is proposed to replace the old
generator, which gives a significant increase in the resource life. Originality. For the first time, the possibility of
upgrading the power system model (УРМЕС-2) by replacing a three-phase signal generator made by a slight
modification of a finished microcontroller unit with digital-to-analog converters, rather than by implementing
software pulse-width modulation of the microcontroller, is shown. Practical significance. The practical value of the
work is to restore the possibility of using numerous laboratory works in the educational process with the use of this
universal analog model of the energy system.
