Energy storage system for electrically operated trolley bus network - holds braking energy as kinetic energy via flywheel at stationary point along each line section

摘要

The energy storage system is used for temporary storage of the braking energy of a trolley bus (8) supplied from an overhead line (4), with subsequent conversion of the stored kinetic energy into electrical energy for providing acceleration. Each section of the line has an associated flywheel (1) at a stationary point, with a smaller flywheel (6) incorporated in each trolley bus, with a microprocessor (9) responding to the charge level of the flywheels and the travel parameters of the bus, to control the regulating devices (2, 5) of each flywheel. ADVANTAGE - Improved energy efficiency and back-up energy supply.
