Title: TWO-SHAFT GAS TURBINE POWER GENERATION EQUIPMENT
Abstract:
This two-shaft gas turbine equipment is provided with: an induction motor (22) which transmits and receives power to and from an external system (1); and a speed reducer (40) which makes the rotational speed of a motor rotor (22r) of the induction motor (22) lower than the rotational speed of a compressor rotor (11r) of a two-shaft gas turbine (10). The speed reducer (40) includes: a compressor-side shaft (41); a motor-side shaft (42); a first compressor-side helical gear (43) and a second compressor-side helical gear (44) which are attached to the compressor-side shaft (41); and a first motor-side helical gear (45) and a second motor-side helical gear (46) which are attached to the motor-side shaft (42). The first compressor-side helical gear (43) meshes with the first motor-side helical gear (45), and the second compressor-side helical gear (44) meshes with the second motor-side helical gear (46).
