GAS TURBINE AND METHOD OF CONTROLLING A GAS TURBINE AT PART-LOAD CONDITION
First Claim
Patent Images
1. A method of operating a gas turbine at a reduced load, the method comprising:
- operating a gas turbine at multiple sets of operational parameters;
measuring at least one output response of the gas turbine at each of the sets of operational parameters;
creating a database at least partially including correlations of each of the sets of operational parameters with the measured output response;
determining a desired reduced gas turbine load;
selecting a set of operational parameters from the database that provides the desired reduced gas turbine load and that meets a target level for the output response; and
further operating the gas turbine at the selected set of operational parameters.

Abstract
A gas turbine includes a compressor section, a combustion section downstream from the compressor section, a turbine section downstream from the combustion section, and a controller. The controller controls the operation of the gas turbine at a reduced load, and is capable of querying a database including multiple sets of operational parameters for the gas turbine correlated with at least one measured output response at each set of operational parameters. One of the sets of operational parameters provides a desired gas turbine load that meets a target level for the output response. Related methods are also disclosed.
