A hybrid power generation system and a method thereof

摘要

A hybrid power generation system (10) includes a gas turbine engine system (12) and a supercritical rankine cycle system (14). The gas turbine engine system (12) includes a first compressor (18), an intercooler (34), and a second compressor (20). A first compressor (18) is configured to compress an inlet airflow (30) to produce a first outlet airflow (32) at a first pressure. An intercooler (34) is coupled to the first compressor (18) and configured to cool the first outlet airflow (32) exiting the first compressor (18) to produce a second outlet airflow (36). A second compressor (20) is coupled to the intercooler (34) and configured to compress the second outlet airflow (36) exiting the intercooler (34) to produce a third outlet airflow (38) at a second pressure. The supercritical rankine cycle system (14) is coupled to the gas turbine engine system (12). The supercritical rankine cycle system (14) is coupled to the intercooler (34) to circulate a working fluid in heat exchange relationship with the first outlet airflow (32) to heat the working fluid at a supercritical pressure from a first temperature to a second temperature above a critical temperature of the working fluid and to cool the first outlet airflow (32) exiting the first compressor (18).
