OPERATION CONTROL METHOD FOR TWO-AXIAL GAS TURBINE, TWO-AXIAL GAS TURBINE, AND OPERATION CONTROL DEVICE FOR TWO-AXIAL GAS TURBINE

摘要

PROBLEM TO BE SOLVED: To restrict deterioration of compressor efficiency in partial load operation of a gas turbine, and secure a surge margin of a compressor in a two-axial gas turbine. SOLUTION: This method includes both a first process to reduce the rotation speed of the compressor and a second process to decrease actuation air quantity in the compressor in changing operation for lowering a prescribed load.
