摘要： A gas turbine control device for a gas turbine system includes a sensing unit for measuring the rotor speed and the output of the power generator; a speed regulation rate setting unit for calculating an actual speed regulation rate based on the measured rotor speed and the measured output of the power generator, and for setting a reference speed regulation rate based on the actual speed regulation rate and the target speed regulation rate; and a fuel amount control unit for controlling an amount of fuel supplied to the combustor based on the set reference speed regulation rate. Stable system operation is secured by a method of controlling the gas turbine system to satisfy a target speed regulation rate if additional power should be supplied due to sudden load fluctuations or a failure at another power plant.

摘要： A gas turbine engine is disclosed which includes a bypass passage that in some embodiments are capable of being configured to act as a resonance space. The resonance space can be used to attenuate/accentuate/etc a noise produced elsewhere. The bypass passage can be configured in a number of ways to form the resonance space. For example, the space can have any variety of geometries, configurations, etc. In one non-limiting form the resonance space can attenuate a noise forward of the bypass duct. In another non-limiting form the resonance space can attenuate a noise aft of the bypass duct. Any number of variations is possible.

摘要： A carbon dioxide cycle power generation system includes storage collectively storing portions of carbon dioxide liquid and gas and a transfer connection selectively directing flow of the carbon dioxide through a turbine. The system cycles between different seawater depths in order to employ at least one of seawater pressure and seawater temperature in creating the carbon dioxide flow. Inlet/outlet control valves on variable volume tanks, positioned below movable pistons within the respective tank, selectively allow seawater into or out of a lower portion of the respective tank below the piston to pressurize the carbon dioxide therein relative to the carbon dioxide within the other tank when at depth rather than near the surface. Inhibited versus uninhibited heat transfer between storage portions and the seawater allows different seawater temperatures at depth and near the surface to create the carbon dioxide flow. Acoustic communications may be driven concurrent with the turbine.

摘要： An engine that has, in axial flow series, booster compressor, core compressor, combustion equipment, core turbine, and low-pressure turbine. Core turbine drives core compressor via an interconnecting high-pressure shaft. Low-pressure turbine drives booster compressor via an interconnecting low-pressure shaft. Low-pressure turbine also drives external load having a defined speed characteristic that dictates speed of the low-pressure turbine and booster compressor. Booster compressor has one or more rows of variable stator vanes. The method includes: scheduling variation in the angle of variable stator vanes as a function of speed of the booster compressor wherein the vanes open as booster compressor speed increases; measuring or setting one or more operational parameters which are determinative of temperature at entry to core turbine; and biasing scheduling of angle variation of variable stator vanes as a function of operational parameter(s) to reduce variation in temperature at entry to core turbine.

摘要： A valve control device is provided in a gas turbine having a combustor for generating combustion gas, a turbine driven by the combustion gas generated by the combustor, a flow rate regulating valve for regulating the flow rate of the fuel to be supplied to the combustor, and a pressure regulating valve disposed upstream of the flow rate regulating valve, for regulating the fuel pressure. The valve control device controls the opening degree of the valve. The valve control device includes a load decrease detection part which detects a load decrease of the gas turbine, and a pressure control part which controls the opening degree of the valve in accordance with the output of the gas turbine. The valve control device suppresses instability of the gas turbine output even when the load rapidly decreases.

摘要： Sensor-based, performance-seeking control of gas turbine engines is disclosed. An example method of controlling a gas turbine engine may include varying an engine input parameter while operating the gas turbine engine to produce a desired output, including measuring a pre-adjustment value of an engine operating parameter with an engine input parameter at an initial value, adjusting the engine input parameter to a current adjusted value, and measuring a post-adjustment value of the engine operating parameter. The method may include determining a future adjusted value of the engine input parameter and iteratively repeating the varying the engine input parameter operation and the determining the future adjusted value of the engine input parameter operation. The method may be performed while operating the gas turbine engine to produce a desired output.
