Abstract: A dispatch advisor for operating a power plant having at least one gas turbine with flexibility is described. The dispatch advisor can generate a representation of a flexible base load map for operating the power plant. The representation can include an aggregation of a primary base load operating space and an expanded portion of the base load operating space. The representation offers a range of operating values for operational parameters of the power plant during base load at various base load settings at predetermined ambient conditions and corresponding power output and efficiency values that are attained while operating the power plant at the range of operating values. This offers an operator of the power plant with flexibility in controlling the plant during base load.

Abstract: A gas turbine engine comprises a primary fan and an engine core. The primary fan is mounted for rotation about an axis of the gas turbine engine to provide thrust. The engine core is coupled to the primary fan and configured to drive the primary fan about the axis to cause the fan to push air to provide thrust for the gas turbine engine.

Abstract: An output corrector is provided with an adjustment coefficient creating unit which creates an adjustment coefficient, an output adjusting unit which adjusts a control output using the adjustment coefficient, and an output accepting unit which accepts an output from an output meter for detecting the output of a gas turbine. The adjustment coefficient creating unit includes a first coefficient element calculating unit which calculates a first coefficient element, a second coefficient element calculating unit which calculates a second coefficient element, and an adjustment coefficient calculating unit which calculates the adjustment coefficient using the first and second coefficient elements. The first coefficient element is the ratio of an immediately preceding output in an immediately preceding time period, to a reference output at a reference time point in the past. The second coefficient element is the ratio of the current output in the current time period, to the immediately preceding output.

Abstract: Exemplary embodiments are disclosed of variable frequency drive (VFD) controllers with engine fail-over and systems including the same. In exemplary embodiments, a system includes a controller configured to be operable for controlling a VFD that drives a motor (e.g., a three-phase AC motor, etc.), which, in turn, drives (e.g., mechanically spins, etc.) a first pump. The same controller is also configured to be operable for controlling an engine (e.g., a diesel engine, etc.), which, in turn, drives (e.g., mechanically spins, etc.) a second pump. The system is configured to failover from the motor to the engine in response to a VFD communications failure.

Abstract: 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.

Abstract: 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.

Abstract: 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.
