Abstract

The article shows the process of building a model of the frequency converter control system for a ship's autonomous power system. This task was solved to simplify the mathematical description of the frequency converter for the ship's autonomous power system. As a result, a mathematical set of probable combinations of operating states of power switches and the corresponding values of generalised voltage vectors of the autonomous inverter using pulse width modulation were obtained. The modelling carried out on the basis of this data confirmed the correspondence of the obtained values of the phase voltage of the autonomous inverter to real energy processes. It is shown that it is important to further study the technical and methodological factors of increasing energy efficiency and the accuracy of the mathematical description of real links of power systems, which will ensure the process of a more qualitative study of energy processes in them.
