GAS TURBINE POWER GENERATION SYSTEM AND METHOD OF DETECTING ITS CALORIE ABNORMALITY

Title:

GAS TURBINE POWER GENERATION SYSTEM AND METHOD OF DETECTING ITS CALORIE ABNORMALITY

Document Type and Number:

WIPO Patent Application WO/2008/056790

Kind Code:

A1

Abstract:

To detect a variation in calorie using available measurements without using a measuring instrument such as a calorimeter. An allowable variation range of gas turbine power generation output with respect to a charged fuel amount or an allowable variation range of a charge fuel amount with respect to a gas turbine power generation output is set from the relation between a charged fuel amount to the combustor of the gas turbine and a gas turbine power generation output and with a fuel gas calorie assumed constant, and calorie abnormality is detected when an actual charged fuel amount or an actual gas turbine power generation output falls outside the allowable variation range.
