Title:
TEMPERATURE SIMULATION METHOD AND APPARATUS FOR TRACTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/077732
Kind Code:
A1
Abstract:
A temperature simulation method and apparatus for a traction system. The method comprises: obtaining driving condition information and operation feature information of an electric locomotive (S101); determining a traction network voltage and a traction torque of a traction system in the electric locomotive on the basis of the driving condition information and the operation feature information (S102); and on the basis of the traction network pressure and the traction torque of the traction system, determining temperature feature information of the traction system corresponding to the driving condition information by using a simulation model that simulates the traction system (S103). Thus, the temperatures of a traction motor of the electric locomotive under target driving conditions can be obtained.
