Advantages Quick start and synchronize to grid O&M easy Less manpower Operating cost low

Disadvantages Starting unit means starting motor, 1305 kw1800 rpm stop, self sustaining speed Compressor power requires Low output efficiency, exhaust high

temperature Combating chamber tem high, so life time

short

Component SMCOMPRESSOR GENERATOR GAS TURBINE TRANSFORMER

Maintenance CI=combustion inspection (flow slip, liner,

transition pitch), after 12000h HGPI= hot gas path inspection (flow slip,

liner, transition pitch, turbine blade, nozzle change generator bearing, turbine bearing, all sensor(tem, vibration) after 24000h )

MI= major inspection (Generator rotor decoupling , retaining ring, generator inspection with HGPI work )
