Should the high-speed rail flywheel energy storage device be used

Do flywheel energy storage systems save energy?

Energy consumption and operating cost with and without flywheels are obtained. Introducing FESS in an LRT can result in substantial energy and cost savings. The maximum predicted energy saving is 31%. The maximum estimated cost savings is 11%. The introduction of flywheel energy storage systems in a light rail transit train is analyzed.

Does a light rail transit train have flywheel energy storage?

The introduction of flywheel energy storage systems in a light rail transit train is analyzed. Mathematical models of the train, driving cycle and flywheel energy storage system are developed. These models are used to study the energy consumption and the operating cost of a light rail transit train with and without flywheel energy storage.

How does a train flywheel work?

A flywheel is installed in each train car and is used to store energy during braking and power the vehicle during the acceleration phase.

How can a light rail transit train save energy and cost?

Cost savings of 11% can be obtained by utilizing different flywheel energy storage systems with 1.2 kWh and 360 kW. The introduction of flywheel energy storage systems in a light rail transit train can therefore result in substantial energy and cost savings. 1. Introduction

Can energy storage devices improve regenerative brakes?

This paper reviews the application of energy storage devices used in railway systems for increasing the effectiveness of regenerative brakes. Three main storage devices are reviewed in this paper: batteries, supercapacitors and flywheels. Furthermore, two main challenges in application of energy storage systems are briefly discussed.

How much energy does a fess traction system save?

The average kinetic energy per vehicle at half-full loading is around 1.2 kWh, which renders system B attractive because of its capacity of 1.19 kWh. Both FESS are equipped with electrical systems. To maximize the energy savings potential, system A is equipped with the maximum electrical power of the traction package, i.e., 725 kW.
