Modeling of asynchronous traction motor operation modes while turning locomotive wheelsets bandages

摘要

At present special machines with built-in electric drives, including the electric drive of rotation of the wheelset, are used for turning the wheelset bandage without moving it from the locomotive. On the other hand, to move the locomotive to the turning point of the bandage, it is necessary to use an external power source of the asynchronous traction motor of the locomotive, since there is no contact network in the depot. Therefore, It is proposed to use the asynchronous traction motor of the locomotive to rotate the wheelset while turning the bandage. As an external power source of the asynchronous traction motor of a locomotive, a modern general-purpose frequency converter can be used. Modeling in the MatLab environment of the operation modes of a frequency electric drive with an asynchronous traction motor and a general industrial frequency converter has been carried out during turning of locomotive wheelsets. The obtained results can be useful for specialists of frequency electric drives based on common industrial converters in solving alternative control tasks.
