Abstract

One of the priority directions in the development of power engineering is to increase energy efficiency in electrical systems, in particular, in AC electric drives. An increase in the efficiency coefficient as well as a decrease in the weight and size indicators of high-power electric drive systems lead to a significant reduction in capital costs. To date, a lot of research and development of energy-efficient electric drive systems is underway. The article suggests an alternative method of implementing an alternating current electric drive based on a dual-power machine (DPM) with a direct frequency converter (DFC). The article describes the main elements of the electric drive under consideration, justifies the decision to use an alternative implementation of a frequency converter based on an DFC and a PWM converter with an intermediate link. The authors proposed and considered the possibility of using a transformer with a rotating magnetic field (RMF) The article describes the main elements of the electric drive under consideration, justifies the decision to use an alternative implementation of a frequency converter based on an DFC and a PS converter with an intermediate link. The authors proposed and considered the possibility of using a transformer with a rotating magnetic field (RMF) as such an intermediate. A functional diagram of such an electric drive is presented, on the basis of which a simulation model is built in Simulink. For a comparative analysis, a control system simulation with a three-phase DFC and a system with a DFC based on RMF was performed. Based on the simulation results, a harmonic analysis of the output voltage of the frequency converter was carried out. In conclusion, the main advantages of such an electric drive over the classical variants are presented.

Keywords
