Patent ID: 7028461

Claim:
A uniaxial gas turbine system comprising: a uniaxial gas turbine; a rotary machine driven by said uniaxial gas turbine; a continuously variable speed transmission of transmitting a drive force from said uniaxial gas turbine to said rotary machine; and a controller of controlling a revolution speed of said uniaxial gas turbine to an optimal revolution speed and controlling a speed variation ratio of said continuously variable speed transmission so as to set a revolution speed of said rotary machine to a desired revolution speed, wherein said continuously variable speed transmission is a continuously variable speed transmission of a power split system for distributing and transmitting said revolution speed of said uniaxial gas turbine, said continuously variable speed transmission has a traction drive disposed on a low power side of said continuously variable speed transmission, and a clutch for connecting or disconnecting a transmission of said drive force between said uniaxial gas turbine and said rotary machine is disposed on an input side of said traction drive.
