Using energy balances for processing the results from tests of a single-shaft combined-cycle power plant

Application of the balance method for dividing the overall power output produced by a single-shaft combined-cycle power plant between the steam turbine and gas turbine unit is considered. It is shown that the method can be used for obtaining trustworthy results of thermal tests. The effect of air flowrate taken for gas turbine cooling purposes on the gas turbine unit parameters and indicators is estimated.
