A comparison of the energy efficiency of the traction electric drive of alternating-current electric locomotives based on collector and asynchronous motors

The diesel electric tractor DET-250M2 was the first tractor in the USSR with an all-electric transmission. This tractor usually works in agriculture as a cultivator and a bulldozer. However, it is often used in the railway sector, in industry, in large construction projects. Since the tractor’s electrical installation developed in the 1950s on the basis of DC collector machines is now obsolete, difficult to maintain, it was decided to upgrade the traction electric drive. The article presents the calculations of an electric machine: optimization of the rotor geometry, selection of the optimal ratio of the pole and interpolar gap, selection of the optimal number of poles of the machine, selection of the current shape, type of rotor. As an electric machine, a FRRM, which characterized by high overload capacity, a wide range of work in terms of torque and speed, was selected.

The principles of pumping station control, providing the most efficient modes of operation are discussed in the article. To perform calculations of energy-efficient operation modes, a mathematical description of the system has been proposed. It is shown that the increase of energy efficiency in the system is achieved by choosing a power circuit, splitting up sections of the pumping station, selecting the appropriate operation algorithms for each of the sections. An electrical equivalent circuit of the control object is proposed. Comparison of the energy consumption of the pumping station was carried out for the following cases: in the first, the cascade did not work, and in the second, the flow was controlled in a cascade over the entire range of flow variation. It is established that the proposed control algorithms can significantly reduce energy consumption from the mains supply by about 30%.
