A gas turbine combustion system having: a plurality of combustion chambers; a plurality of fuel nozzles for each of combustion chamber; a plurality of manifolds for supplying fuel to at least one fuel nozzle in each of the combustion chambers; each of the manifolds having fuel trim control valves for the fuel nozzles, wherein the fuel trim control valves are mounted on the multiple manifolds for metering the fuel to the fuel nozzles in the combustion chambers, and a trim valve controller automatically actuates one or more of the fuel trim valves to adjust fuel to the fuel nozzles based on gas turbine operating conditions.

The gas turbines of the present invention have multiple combustion chambers, and within each chamber are multiple fuel nozzles. Each nozzle has its own fuel control valve to control the fuel flowing to the nozzles. To minimize the pressure drop through the fuel control valves, multiple manifolds are employed. Each manifold supplies at least one fuel nozzle in multiple combustion chambers with fuel. The fuel control valves are mounted on the manifolds such that the weight of the fuel control valves and nozzles are carried by the manifolds, not the multiple combustion chambers. A plurality of thermocouples for measuring exhaust gas from said multiple combustion chambers are employed to sense gas exhaust temperature. In carrying out the methods of the present invention for tuning a gas turbine, it is essential to note that the most efficient gas turbine is one which has the least nitrous oxides, the least amount of unburned hydrocarbons, and the least amount of carbon monoxide for a specified energy output. In order to tune the gas turbine to accomplish these objectives, it is desirable that each combustion chamber in the gas turbine be well balanced relative to the remaining combustion chambers. It is an aim of the present invention to tune each of the multiple combustion chambers such that no specific combustion chamber is rich or lean, and all are operating within about 1% of the remaining combustion chambers.

Systems and methods are provided for supporting and articulating a payload using stabilization platform. The stabilization platform may be configured to avoid gimbal lock. The stabilization platform may be configured to automatically transition between different modes of orientation.

An optical element holding structure, having: an optical element including an optical section having optical function, an outer peripheral portion which is positioned at the outer peripheral side of the optical section and a mounting portion which protrudes from the outer peripheral portion in a direction substantially parallel to the optical axis; and a lens barrel holding the optical element inside.

In a motor drive control system configured to include a converter capable of stepping up the voltage, when the locked state of MG2 operating as an electric motor does not occur (NO in S130), a voltage command value VHref for the converter output voltage is set according to respective required voltages of MG1 operating as an electric generator and MG2 (S140). In contrast, when the locked state of MG2 occurs (YES in S130), the voltage command value VHref is set to a limit voltage Vlmt or less for limiting the voltage step-up by the converter (S150, S180). When the locked state occurs, the converter output voltage is decreased and accordingly the DC voltage switched by the inverter is lowered, so that a switching loss at the switching device forming a part of the inverter is reduced and the temperature increase due to the heat generation can be suppressed.

The present technology includes a setting unit that sets the position of a boundary of image data in an upper hierarchy unit to be in a lower hierarchy unit that is lower than the upper hierarchy unit when the image data is encoded in a unit of encoding with a hierarchical structure; an encoding unit that generates encoded data by encoding the image data according to the position of the boundary set by the setting unit; and an addition unit that adds information on the image data in the upper hierarchy unit before encoded data in an intermediate hierarchy unit that includes the boundary set by the setting unit, is lower than the upper hierarchy unit, and is higher than the lower hierarchy unit. The present technology can be applied to, for example, an image processing device.
