METHODS AND SYSTEMS FOR ESTIMATING COMPRESSOR FOULING IMPACT TO COMBINED CYCLE POWER PLANTS

摘要

PROBLEM TO BE SOLVED: To provide a system and method for estimating the impact of compressor fouling in a combined cycle power block (100).

SOLUTION: A current performance of the combined cycle power block (100) is determined and normalized to one or more reference conditions. A baseline performance of a gas turbine (105) of the combined cycle power block (100) is also determined. A predicted performance of the combined cycle power block (100) is then determined by subtracting the baseline performance of the gas turbine (105) from the current performance of the gas turbine (105). A recoverable impact to the combined cycle power block (100) due to compressor fouling is then determined by subtracting the normalized current performance from the predicted performance and a recoverable impact to the fuel consumption of the combined cycle power block (100) is determined from the recoverable impact.
