This paper presents a hypothetical conversion of a conventional heavy haul diesel-electric locomotive to its hybrid counterpart by incorporating a battery energy storage system. Starting from the basic parameters of a 1.6 MW diesel-electric locomotive currently found in the national railway company locomotive fleet, the quasi-static model …

Traction converter for multi-system locomotive

Adapting and providing solution to this reality, CAF Power & Automation has developed multi-system electric traction converters. Applying the modularity concepts in the design stage, our traction converters can be adapted to various existing catenary voltages, i.e. both to AC catenaries (25kV, 15kV) and DC catenaries (3kV, 1.5kV).

Schemes of energy exchange in locomotive traction electric drive and auxiliary systems: a) – traction mode when movement on the site for the 1 st Scenario; b) – traction mode when movement on the site for the 2 nd Scenario; c) – traction mode when driving on the site for the 3 rd Scenario; d) – traction mode when maneuvering; e) – …

Journal of Energy Storage

In this study, we consider three platforms for decarbonisation, a battery electric locomotive (BEL), battery electric tender (BET) and a hydrogen electric tender (HET) (Fig. 2).Also shown in Fig. 2 are the usable energy capacities of these platforms (MWh), based on current commercial technology and future technologies expected to be …

Energy efficiency in railways: Energy storage and electric generation in diesel electric locomotives …

Diesel-electric traction is a well known and established technology for railways operators, but this alternative has a considerable uncerainty for the future because electric traction has a considerable superiority. Besides, diesel-electric engines waste energy when resistivebraking is used. This non-regenerative braking decreases the …

Battery Electric Locomotives & Battery Tenders: Operational & Infrastructure Challenges to Widespread …

Abstract. The potential use of large storage batteries to provide onboard propulsion energy for freight railroads is gaining significant attention. Even though at least 126 Battery Electric Locomotives have been tested, built and operated in the U.S. since 1920, diesel-electric locomotives remain dominant. Several new Battery Electric …

Application of flywheel energy storage for heavy haul locomotives

On the Use of Battery-Electric Locomotive as a Grid-Support Service in Electric …

Harvesting wind energy is constrained by its generation availability and variability. Energy storage systems (ESSs) partly address this limitation by absorbing the generation volatility and curtailment. However, the conventional static ESSs may lack the necessary reach and versatility to effectively support large-scale power systems. This paper presents an …

Comparison of locomotive energy storage systems for heavy-haul …

ABSTRACT This paper modelled flywheel and battery energy storage systems for heavy-haul locomotives. Three heavy-haul trains with their traction power provided by diesel, diesel-flywheel, and diesel-battery locomotive consists were simulated on an existing railway. The diesel, flywheel, and battery locomotives have traction …

Trading off energy storage and payload – An analytical model for …

Battery-electric locomotive energy requirements are estimated based on the current diesel fuel consumption by Class I railroads which is then adjusted by the relative energy efficiency of battery-electric to diesel powertrains (Popovich et al., 2021).

(PDF) Thermal Analysis of an Energy Storage System for a Battery Electric Switcher Locomotive …

The results show that between 22% and 30% fuel cost savings may be achieved, along with reduced emissions of exhaust gases by using the proposed battery-electric locomotive in combination (tandem ...

Reduction of Energy Consumption by Electric Rolling Stock of …

It was established, that the use of an on-board energy storage system on an electric locomotive provides a reduction of energy consumption by approximately 10% and it is practically independent of the energy storage power. The maximum power consumed from the traction network is reduced during the exploitation the on-board …

Comparative analysis of conventional diesel-electric and hypothetical battery-electric heavy haul locomotive …

It is assumed that the battery-electric locomotive can be realized by retrofitting a sufficiently-sized battery energy storage system utilized onto the base undercarriage of a decommissioned conventional 1.6 MW/103 ton diesel-electric locomotive [38], i.e. by

ENERGY EFFICIENCY IN RAILWAYS: ENERGY STORAGE AND ELECTRIC GENERATION IN DIESEL ELECTRIC LOCOMOTIVES

ENERGY STORAGE IN RAILWAYS. Supercapacitors (SC), flywheels and Supermagnetics Energy Storage (SMES) are new components that can be used for short-duration energy storage [3],[4]. For example, the University of Texas at Austin Center for Electromechanics (UT-CEM) is currently developing an Advanced Locomotive Propulsion System (ALPS) …
