摘要： A method for controlling the generation of turbine cooling air from air extracted from a compressor of a gas turbine including: extracting compressed air from a low pressure and a high pressure stage of the compressor; adding in an ejector the compressed air from the low pressure stage to the air from the high pressure stage and discharging the combined air as turbine cooling air; bypassing the ejector with a bypass portion of the extracted compressed air from the high pressure stage; in response to turning on the flow of extracted compressed air from the low pressure stage, changing a set point for an actual pressure ratio that includes a pressure of the turbine cooling air, and adjusting the bypass flow in response to the changed set point to cause the actual pressure ratio to approach the changed set point.

摘要： A method for controlling and modeling a turbine is provided. The method may include modeling the turbine by a primary adaptive turbine model that includes at least one primary operating parameter and modeling the turbine by an alternate adaptive turbine model that includes at least one alternate operating parameter. The method may also include determining a first output value from the primary adaptive turbine model that corresponds at least in part to the operation of the turbine based on a primary control strategy and adjusting the alternate operating parameter or parameters based on an alternate control strategy and based at least in part on the first output value. The method may further include determining comparison data based at least in part on a comparison between the primary control strategy and the alternate control strategy.
