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.
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.
A flywheel is installed in each train car and is used to store energy during braking and power the vehicle during the acceleration phase.
Patented technology used within the flywheel system includes a high-speed motor generator and contact-free magnetic bearings that levitate and sustain the rotor during operation. Flywheel systems can accelerate and decelerate at extremely high rates, enabling them to charge and discharge energy in seconds.
Our standardized photovoltaic container and energy storage products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
