System and method for simulating a gas turbine compressor

摘要

A method (100) for simulating a compressor of a gas turbine is disclosed. The method may generally include determining (102) a predicted pressure ratio and a predicted mass flow of the compressor based on a model of the gas turbine, monitoring (104) an actual pressure ratio and an actual mass flow of the compressor, determining (106) difference values between at least one of the predicted pressure ratio and the actual pressure ratio and the predicted mass flow and the actual mass flow, modifying (108) the difference values using an error correction system to generate a compressor flow modifier and using (110) the compressor flow modifier to adjust the predicted pressure ratio and the predicted mass flow. And a corresponding system for simulating a compressor (12) of a gas turbine engine.
