Abstract
Today, the tasks of analyzing the influence of frequency fluctuations on the quality of the rectified voltage are not well understood, and the problems of compensating for such an effect have not been solved. The aim of the work is to study the influence of frequency fluctuations of autonomous electric power systems on the quality indicators of the voltage of controlled rectifiers and the development of hardware and software tools designed to reduce the effect of frequency fluctuations on the rectified voltage. Object of study: is an autonomous (ship) electric power system with engines up to 2000 kW. To test theoretical studies, simulation was used in the Matlab-Simulink environment with parallel experimental studies. As a result of research, it was found that specialized pulse-phase control systems can reduce the influence of frequency fluctuations to the required values, but lead to a certain complication of rectifier control systems.
