Method for specifying turbine entry temperature of gas turbine in unsteady conditions involves determining by combination of turbine entry temperature in stationary mode and correction term

摘要

The turbine entry temperature (T41, transient) in unsteady conditions is defined as the calculated value for the turbine entry temperature (T41, stationary) in stationary operation and the correction term (Delta T41, transient). The correction term is specified as the sole correction accelerator which is determined from the measured number of revolutions (Nv), the revolution changes per unit time (Nv%t), the weight transfer moment of the shaft, the measured pressure (P2) and the measured temperature (T2) at entry in the impeller of the gas turbine (1).
