Justification of the Structure of the Electric Traction Drive of the Electric Locomotive for Railway Quarry Transport

Purpose. The study is aimed at substantiating the structure and determining main parameters of traction electric drive an locomotive for railway quarry transport, taking into account its modes operation. Methodology. research was carried out by means mathematical modeling, which included solving problem evaluating energy exchange processes between components drive. simulation movement train along track section during shunting, differ significantly in their description. During section, solved using recommendations calculations A simplified model developed to simulate movements shunting. Determination analyzing based on power balance. studies, it assumed that on-board storage mode feeds motors booster section. In electrodynamic braking mode, accumulator stores from all locomotive. Findings. authors obtained time dependences characterize stages cycle «empty half passage – loading loaded unloading» (on example PJSC «Ferrexpo Poltava Mining»). analysis dependencies made possible determine proposed operation scenario. It established capacity should be 250 kWh one cycle. 6000 kW. Originality. this paper first control are powered catenary network, a load exceeds 50% nominal one. Practical value. practical value lies models processes, can applied drives vehicles various purposes.
