Title: Gas turbine power generating device
Inventor: TOCHIO SHINICHIRO
IPC: H02P9/04
Filed: 2002-05-07
Abstract: <P>PROBLEM TO BE SOLVED: To provide a compact gas turbine power generation device capable of continuing operation even when an accidental fire is generated during operation.  <P>SOLUTION: In this gas turbine power generating device, AC power generated by a permanent magnet power generator driven by a gas turbine is converted by a converter into DC power, this DC power is converted by an inverter into AC power of commercial frequency, a storage battery to store DC power is provided, and output voltage of this storage battery is boosted by a DC booster into AC power, which is then converted by a sub-inverter into AC power of desired frequency to be supplied to the permanent magnet power generator to charge the storage battery. A flywheel is connected to a rotary shaft of the gas turbine power generating device. Even when supply of fuel is stopped, rotation of the gas turbine can be continued by rotation energy accumulated in the flywheel. When an accidental fire is generated during operation of the gas turbine power generating device, rotation speed is less reduced because inertia mass is large, and the accidental fire can be detected while gas turbine is continuing rotation. Fuel is ignited again to restart operation.  <P>COPYRIGHT: (C)2004,JPO
