Abstract
Introduction. The authors considered the problem of increasing the energy efficiency of an asynchronous drive, in particular, auxiliary electric machines of an electric locomotive. The publication continues the topic of optimal control of asynchronous machines from the past articles in No. 5, 2021 and No. 1, 2022 of the Russian Railway Science Journal.
Materials and methods. The calculation of the dynamic characteristics of an asynchronous drive used the SimInTech software of 3V Service, a Russian company, designed to simulate various applied problems. The SimInTech software package was used in the development of a mathematical model of the proposed system for optimal vector control of an asynchronous drive.
Results. The authors have found that the developed system of optimal control enables to reduce the current consumed by the asynchronous drive. These simulation modeling results confirmed that the adopted circuit solutions are correct.
Discussion and conclusion. The proposed system of optimal control of electric locomotive auxiliary machines is designed to improve the energy efficiency of the drive with a new algorithm for selecting the optimal value of the rotor flux linkage by reducing the current consumed by the drive. This vector control structure could be successfully implemented on the basis of modern microcontrollers.
