摘要： The gas turbine system has: a gas turbine having a compressor, a combustor, and a turbine; a fuel supply mechanism for supplying fuel to the combustor; a composition detection unit for detecting the composition of the fuel; and a controller for controlling the flow rate of the fuel supplied from the fuel supply mechanism to the combustor, on the basis of a function of the exhaust temperature of exhaust gas passing through the turbine and either air pressure of air expelled from the compressor to the combustor or an expansion ratio of the turbine. The controller calculates the specific heat ratio of the combustion gas from the composition of the fuel detected by the composition detection unit, corrects the function on the basis of the calculated specific heat ratio, and controls the flow rate of the fuel on the basis of the corrected function.

A fan is arranged upstream from the core nacelle and is coupled to the spool. A fan nacelle surrounds the fan and core nacelle and provides a bypass flow path that includes a fan nozzle exit area. A flow control device is adapted to effectively change the fan nozzle exit area. A controller is programmed to monitor the thrust bearing and command the flow control device in response to an undesired load on the thrust bearing.

摘要： A process quantity measurement method with which an engine output is accurately measured in a relatively simple manner. Torque of an engine is measured based on the amount of torsion of the output shaft of the engine, and an engine output is obtained based on the measured torque. On the other hand, an engine output is calculated based on input and output heat quantity, and a difference between the engine output based on the torque and the engine output based on the input and output heat quantity is obtained in advance. When the engine is operated, the previously obtained difference is added to the engine output that is based on the calculated input and output heat quantity to obtain the engine output.

摘要： The invention suppresses the production of thermal stress in power generating equipment and the unstable behavior of the power generating equipment due to the variation of system frequency and stabilizes the system frequency. A power plant load control system controls the operation of a power plant equipped with a gas turbine comprising a combustor (1) and a turbine (3), and a power generator (5) disposed coaxially with the turbine. The power plant load control system comprises a governor load control unit (100) for determining a governor instruction (103d) on the basis of the deviation of generated power (102d) from a power generation instruction (101d) given thereto by a central load dispatching station according to the variation of system frequency, and for determining a fuel supply rate instruction (107d) corresponding to a speed droop ratio (R) according to the deviation of shaft speed (104d) from a governor instruction (103d). The governor load control unit (100) has a fuel supply rate instruction limiter (107) for limiting the change rate of the fuel supply rate instruction (107d). The fuel supply rate instruction limiter (107) determines a limit to the change rate so that the production of thermal stress in the gas turbine and unstable combustion may be suppressed, and limits the variation of the fuel supply rate instruction (107d) to a range below the limit.
