METHOD OF LOCOMOTIVE ENERGY EFFICIENCY CONTROL WHEN WORKING WITH PARTIAL LOAD Russian patent published in 2017 - IPC B60L15/20 B61C15/00 B60K31/00 B61C17/12 

FIELD: transportation.

SUBSTANCE: method of locomotive energy efficiency control when working with partial load is to regulate the number of simultaneously operating traction engines. Disconnection or connection of traction motors occurs automatically in accordance with the regularity, presented in the form of a functional dependence of the locomotive operational efficiency η on the type capacity use factor γ η=γ/(k₁⋅γ+k₂), where k₁ and k₂ are the factors determined during the locomotive traction and energy tests introduced into the locomotive on-board computer program, which determines the minimum sufficient number of operating traction engines.

EFFECT: increased locomotive efficiency when working with partial load.
