Determination of Parameters for a Plug-In Hybrid Traction System for an Industrial Shunting Locomotive

The paper investigates the operation of shunting locomotives TEM2 and ChME3 at industrial enterprises. By analysing the data from on-board systems for recording motion parameters, the parameters and indicators of operating modes for diesel locomotives performing shunting operations and haulage work are determined. It is established that when performing shunting operations, a diesel locomotive operates with a tangential power not exceeding 150 kW at a maximum traction force of 250 kN. When performing shunting operations, the locomotive operates with a tangential power not exceeding 420 kW at a maximum traction force of 350 kN. It was determined that during shunting operations, energy consumption does not exceed 1000 кВтгод per shift. The use of a plug-in hybrid traction system is proposed to create a unified locomotive. It is predicted that shunting operations will be carried out when powered by a plug-in storage device. In the case of haulage operations, the traction electric drive will be powered jointly by the storage and a diesel generator.
