Abstract |
Curently under development is the Ultra-Low Emission Vehicle Transport using Advanced Propulsion (ULEV-TAP), which is a light-rail vehicle consisting of a Prime Mover Unit comprising a gas turbine and a high-speed generator for average power supply. Other components in the vehicle are a four-quadrant Drive Brake Unit to convert electrical to mechanical energy and vice versa, an Energy Storage Unit for power demand smoothening, Auxiliary devices, e.g. for power supply to controllers, and a Supervisory Control Unit for the overall vehicle control. The Centre for Construction and Mechatronics is concerned with the development of the Energy Storage Unit. To use the EMAFER (Electro Mechanical Accumulator For Energy Re-use) flywheel system in this system, an appropriate power electronic inverter configuration has to be chosen, depending on some integration issues. Several possible solutions are presented and evaluated, supported by simulation results of machine-inverter combinations. Then, a final selection is made. |
