摘要： There is described a shaft shear event detection method. The method comprises obtaining a demodulated waveform of a shaft oscillation wave superimposed on a shaft rotational speed signal, comparing the amplitude to an amplitude threshold, detecting oscillation when the amplitude threshold is exceeded for a plurality of samples, and detecting a shaft shear when oscillation continues for a predetermined time limit.

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： An improved closed loop Brayton cycle for a power plant is provided that includes a heater, at least one turbine, a recuperator, at least one cooler, at least one compressor, a bypass line and a flap valve arrangement in a closed circuit in which working fluid is circulated to produce electricity via a generator. Depending upon the requirement, such as, in case of gird load disconnection, speed of a shaft-line to which the turbine, the compressor and the generator are configured is also required to be reduced without any impact on the pressure drop in the cycle. For that the non-tight flap valve arrangement is configured on each conduit between the heater and the at least one turbine in a closest possible proximity to each turbine inlet.

摘要： A method for operating a gas turbine includes supplying fuel via at least one control valve regulated using an open-loop control system based on a predetermined load setpoint value. A valve stroke control command (scmd) is generated based on a fuel mass flow control command (mcmd) using a mass flow-valve stroke converter. The valve stroke control command (scmd) is compared with a valve stroke limit value (min{slim1, slim2}) using a variable pressure regulator. A load limit value is generated if the valve stroke control command (scmd) exceeds the valve stroke limit value (min{slim1, slim2}) to reduce the load setpoint value. Operation of the gas turbine is stabilized using a low limit value (xlim) of a pressure drop ratio (x), wherein the pressure drop ratio (x) is a quotient of a pressure drop (dp) which occurs at the control valve and of a pressure (p1) upstream of the control valve.

摘要： A method to detect shaft break includes monitoring first and second parameters and defining a two-dimensional parameter space that is a function of the first and second parameters, the two-dimensional parameter space includes integration regions. The method also includes defining an integration function for each integration region. For measured values of the first and second parameters, the method determines the applicable integration region and applies the integration function to the first parameter to give an integration result; and then sets a shaft break signal to TRUE when the integration result exceeds a predetermined threshold. The present invention also provides a shaft break detection system.

摘要： A method, system and generator for controlling a flow of fuel during a shut down of a gas turbine generator is disclosed. A first fuel flow rate to a combustion flame of the gas turbine generator is set at a beginning of a shut-down sequence. A sensor is configured to measure a rotation rate of a turbine rotor of the generator. A processor determines a deceleration of the turbine rotor from the measured rotation rates corresponding to the first fuel flow rate and compares the determined deceleration to a selected criterion. When the deceleration matches the selected criterion, the processor adjusts the fuel flow rate from the first fuel flow rate to a second fuel flow rate.
