Abstract
Provided is a two-shaft gas turbine power generation equipment that includes: an induction motor which receives/transmits power from/to a power system; and a speed reducer that makes a rotational speed of a motor rotor of the induction motor lower than a rotational speed of a compressor rotor of a two-shaft gas turbine. The speed reducer includes: a compressor-side shaft; a motor-side shaft; a first compressor-side helical gear and a second compressor-side helical gear which are mounted on the compressor-side shaft; and a first motor-side helical gear and a second motor-side helical gear which are mounted on the motor-side shaft. The first compressor-side helical gear meshes with the first motor-side helical gear, and the second compressor-side helical gear meshes with the second motor-side helical gear.
