摘要： This control device for a gas turbine connected to a power generator capable of linking to a power system is configured to be able to switch operation modes of the gas turbine between a normal operation mode in which the gas turbine rotationally drives the power generator and a reverse power operation mode in which the gas turbine is rotationally driven by the power generator actuated as a motor by receiving power from the power system, the control device comprising: an index acquisition unit configured to acquire an index indicating the pressure ratio of a compressor of the gas turbine; and a signal output unit configured to output a signal for protecting the compressor when the index becomes less than a threshold value while the gas turbine is operating in the reverse power operation.

摘要： The present disclosure provides methods and systems for determining a synthesized engine parameter of a gas turbine engine. An initial model parameter is obtained from an onboard model associated with the gas turbine engine. A correction factor for the onboard model is determined by modifying a difference between the onboard model and an aero-thermal model of the gas turbine engine using first and second engine parameters and first and second operating conditions, wherein the first and second engine parameters are independent from one another over an operating envelope of the gas turbine engine. The initial model parameter is scaled by applying the correction factor thereto to obtain a corrected model parameter. The corrected model parameter is output as the synthesized engine parameter.

摘要： A method for in-flight monitoring of the health of an aero gas turbine engine including in flow series a compressor system, a core gas generator including a combustor, and a turbine, and further including a shaft system connecting the turbine to the compressor system and forming a torque path there between. The method includes: measuring a first rotational speed of a forward portion of the shaft system; measuring a second rotational speed of a rear portion of the shaft system; measuring other operational parameters of the engine; calculating from the measured rotational speeds the power delivered by the torque path from the turbine to the compressor system; calculating from the other measured operational parameters the power delivered to the turbine by the core gas generator; correlating the power delivered by the torque path at a given time with the power delivered to the turbine at that time.
