摘要:
Discloses is a turbine power generation system having an emergency operation means and an emergency operation method therefor that are capable of controlling excess heat accumulated during emergency operation, and recycling the accumulated heat. A turbine power generation system includes: an inlet sensor part including a thermometer, a pressure gauge, and a flowmeter that are installed between the heater and the inlet valve and; an emergency discharge part including a branch pipe connected to the steam, and a heat control means installed on the branch pipe. Accordingly, the system and the method are capable of reducing a heat overload during an emergency operation by transferring a heat amount exchanged in the heat storage device to the heat consuming facility, minimizing thermal consumption by recycling the same, and preventing various problems caused by stopping an operation of the turbine power generation system.

A pipe fault detection system (200) is provided for a gas turbine engine (100) having a compressor (112) and a turbine (114). The pipe fault detection system (200) includes a cooling manifold (202) configured to direct cooling air from the compressor (112) to the turbine (114). The cooling manifold (202) includes at least two cooling pipes (202) a sensor (214) configured to detect an operating condition indicative of a pipe break, and a controller (176) configured to control the amount of cooling air through the cooling manifold (202) in response to the operating condition detected by the sensor (214).

A sensor element for use in a backing sensor to monitor a gas turbine shaft. The sensor includes an oscillator circuit (30) having an oscillator and a resonance circuit (42), and a frequency detector (31) for monitoring the frequency of the ossilation circuit. Abnormal movement of the shaft cuts the circuit in the sensor along a cutting line (15). The cutting of the sensor changes the capacitance and/or inductance of the resonance circuit and thereby changes the frequency of oscillation.

The invention relates to a method for automatically controlling an operating speed of a helicopter turboshaft engine, including a step (10) of receiving data (27, 28, 29) that represent the flight of the helicopter; a step (11) of selecting the turboshaft engine for which a change in speed would be more relevant; a step (12) of determining an operating speed of said turboshaft engine, referred to as chosen speed, selected among a plurality of predetermined operating speeds; and a step (14) of controlling the operating speed of said turboshaft engine to said chosen speed. The invention also relates to a corresponding control device.

The invention relates to a method for controlling a turbine engine (5) which includes a compressor (8), a combustion chamber (9), first and second turbines (10, 12), a first rotary shaft (11) rotatably secured to said compressor and to said first turbine, a second rotary shaft (13) to which the second turbine is rotatably secured, said second rotary shaft being freely rotatable relative to the first rotary shaft, and a controller (15) for controlling the fuel supply to the combustion chamber. Said controller interrupts the fuel supply to the combustion chamber if a speed of rotation (N2) of said second rotary shaft exceeds a maximum threshold (N2imax) which varies according to at least one indicative physical parameter associated with a mechanical power extracted from combustion gases in the second turbine.
摘要:
La présente invention concerne une installation motrice (10) munie d'un premier turbomoteur (11) et d'un deuxième turbomoteur (16) et d'un système (20) de secours d'injection de fluide dans lesdits turbomoteurs (11, 16). Une première et une deuxième conduites de pressurisation (26, 28) relient un réservoir (21) à chaque générateur de gaz des turbomoteurs. De plus, le système (20) comporte un dispositif d'injection (35, 40) par turbomoteur comportant une conduite d'injection (36, 41) reliant ledit réservoir (21) à au moins une buse d'injection (31). Un distributeur (51, 52) est disposé le long de chaque conduite d'injection (36, 41), chaque distributeur (51) alimentant un turbomoteur étant relié au générateur de gaz de l'autre turbomoteur.
