Abstract
The efficiency of the Aero Gas Turbine in a combine cycle power plant (CCPP) is maximum under the conditions that the combustion chamber temperature is highest, the compressor is working at full capacity and all bleed valves are closed. The Inlet Air Heating System is therefore used to improve the efficiency of the machines in low power generation conditions. To ensure stability in response to air temperature and machine capacity changes, this work thus proposes an optimization-based automation system designed to stabilize the CCPP. Results show that under changing conditions, the overall efficiency of the air compressors in low load conditions increases by 3%, shortening the system start time of 15 minutes and improving the efficiency of the combined cycle power plant by an average of 100 BTU / kw.hr. The average fuel cost is reduced by approximately 600,000 baht per month.
