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.
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.
A flywheel is installed in each train car and is used to store energy during braking and power the vehicle during the acceleration phase.
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.
They are currently the focus of industrial and academic research and development. There are some commercially available examples of high-speed flywheels [5, 6]. For instance, flywheels produced by VYCON Energy and Beacon Power are reported in the literature [7, 8]. Flywheels store energy mechanically in a rotating mass.
Traditional flywheel systems require strong containment vessels as a safety precaution, which increases the total mass of the device. The energy release from failure can be dampened with a gelatinous or encapsulated liquid inner housing lining, which will boil and absorb the energy of destruction.
