摘要： This combustion adjustment method applied to the combustion control of a combustor executes a first step for selecting a combustion parameter for a load of a gas turbine and increasing or decreasing a command value of the combustion parameter from an original location. When the command value reaches a target tolerance upper limit value or a target tolerance lower limit value, the first step is terminated. Furthermore, a second step for decreasing or increasing the command value in a direction opposite to that of the first step is executed. When the command value reaches the target tolerance upper limit value or the target tolerance lower limit value, the present invention includes a combustion tolerance confirmation step for confirming a combustion tolerance range of the combustion parameter at which the second step is terminated.

摘要： A system and a method for predicting and optimizing remaining hardware life of gas turbine components. Operating parameters of the gas turbine which may impact remaining hardware life are sensed and tracked using a plurality of sensors in communication with a control system including a computing device. Remaining hardware life is predicted using a physics-based hardware lifing model. The hardware lifing model may include an output of a filtration model configured to monitor contaminants based on a pressure drop across a filter. Optimizing the remaining hardware life is achieved by the control system adjusting one or more operation settings of the gas turbine.

摘要： Systems and methods to control performance via control of compressor operating limit line (OLL) protection actions. According to an embodiment of the disclosure, a method of controlling a turbine in a power plant can be provided. The method may include receiving a selection of a desired performance parameter associated with an operational mode of a power plant; receiving a set of measured performance parameters at a current operating condition of a turbine associated with the power plant; receiving an operating limit line (OLL) of a compressor associated with the turbine; and receiving a compressor pressure ratio (CPR) at the current operating condition of the turbine. The method may further include: comparing the CPR to an operating limit pressure ratio on the OLL at the current operating condition of the turbine; based at least in part on the comparison, a difference between the CPR and the operating limit pressure ratio exceeding a predetermined threshold can be determined; and based at least in part on the difference between the CPR and the operating limit pressure ratio, the selection of the desired performance parameter, and the set of measured performance parameters, one or more response actions via a control system of the turbine can be implemented.

摘要： A system and method for controlling air flow through a combustor swirler assembly that includes an inner swirler and an outer swirler. A bistable fluidic amplifier that includes an air inlet, a first air outlet, a second air outlet, and a control port is disposed upstream of the combustor swirler assembly. A flow of compressed is directed into the air inlet of the bistable fluidic amplifier and, based on the control air pressure at the control port, the flow of compressed air supplied to the air inlet is selectively directed to either the first air outlet or the second air outlet.

摘要： A system and method for controlling the operation of a gas turbine engine supplying power to an aircraft. The engine is controlled according to a reading of an amount of power drawn from the supplied power. The reading is fed directly to a control system, which issues commands for controlling engine parameters comprising an acceleration reference signal, load shedding, variable geometry positioning, and fuel flow. The control system may further issue commands for controlling the amount of power drawn. The control system may further use the reading to monitor the engine's condition.

摘要： A gas turbine engine optimization control device estimates a specific fuel consumption using a given control parameter of a variable mechanism, determines a change between a specific fuel consumption estimation value by the control parameter of the variable mechanism in a previous operation period and a specific fuel consumption estimation value by the control parameter of the variable mechanism in this operation period, determines a new control parameter of the variable mechanism with which the specific fuel consumption estimation value approaches a minimum, adds the new control parameter of the variable mechanism to a preset control parameter initial value, and sets the addition value to be a control parameter command value of the variable mechanism in a next operation period.
