How to use flywheel energy storage technology in high-speed rail

What is a flywheel energy storage system?

Energy storage systems (ESSs) play a very important role in recent years. Flywheel is one of the oldest storage energy devices and it has several benefits. Flywheel Energy Storage System (FESS) can be applied from very small micro-satellites to huge power networks.

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.

Can a high-speed flywheel be used as an energy storage device?

Martinez-Gonzalez P. A study on the integration of a high-speed flywheel as an energy storage device in hybrid vehicles (Ph.D. Thesis). Department of Mechanical Engineering Imperial College, London; 2010. Frank AA, Beachley NH, Hausenbauer TC. The fuel efficiency potential of a flywheel hybrid vehicle for urban driving.

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 does a flywheel save kinetic energy?

Flywheel (FW) saves the kinetic energy in a high-speed rotational disk connected to the shaft of an electric machine and regenerates the stored energy in the network when it is necessary . First use of FW regurgitates to the primitives who had applied it to make fire and later, FWs have been used for mechanical energy storage .

What is the energy saving effect of flywheel receptivity?

The method of analysis is based on train movement and electrical-network load-flow simulation. The results of the analysis indicate potential energy saving of up to 21.6% due to the introduction of the flywheel energy storage. The energy saving effects of receptivity (or energy transfer from one train to another) are also considered.
