ANALYSIS OF ENERGY EFFICIENCY OPERATIONAL INDICATORS OF FREIGHT DIESEL LOCOMOTIVES
The article presents analysis of the energy efficiency operational indicators of the freight diesel locomotives by using the trip data from microprocessor control system (recorder of locomotive parameters). The proposed approach for analysis is based on the representation of the energy conversion scheme at two levels, the top one is the diesel-generator set and the lower one is the electric power transmission. The evaluation of the analysis results of the energy efficiency of the freight diesel locomotives is given and recommendations are formulated.
