GAS TURBINE GENERATOR HAVING ADDITIONAL CAPACITY CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a control device for operating a gas turbine so as to maintain desired additional output capacity. SOLUTION: A front end stationary blade angle 210 of a compressor is applied as one indicating additional capacity of a gas turbine. An actual front end stationary blade angle 206 is compared with a desired front end stationary blade angle 210 corresponding to desired additional capacity. By regulating fuel flow to the gas turbine and regulating a turbine output by a control device 200, the actual front end stationary blade angle 206 is kept at a desired valve corresponding to desired additional capacity.
