    Abstract: A control system is provided for a power generating system having a gas turbine, a flue gas exhaust stage and a blow-off valve assembly. The gas turbine includes a compression stage, a combustion stage and a driveshaft. The blow-off valve assembly is configured to selectively provide fluid communication between the combustion stage and the flue gas exhaust stage. The control system includes a controller configured to output a signal causing the blow-off valve assembly to provide the fluid communication in response to a sudden de-loading of the gas turbine.

    Abstract: A steam valve includes: a valve main body which has, on the inside thereof, a flow path through which steam flows, and has a valve seat formed in a portion of the flow path; a valve body which comes into contact with the valve seat, thereby shutting off the flow path, and is separated from the valve seat, thereby opening the flow path; a valve shaft which is connected to the valve body, extends in an upward direction from the valve body, and moves up and down, thereby bringing the valve body into contact with the valve seat and separating the valve body from the valve seat; a hydraulic drive unit which is disposed to be separated in a horizontal direction from the valve main body, at a position which does not overlap the valve main body in a case of being viewed from above, and has a drive rod which is driven forward and backward by oil pressure; a first link unit which connects the drive rod and the valve shaft and transmits the forward and backward drive of the drive rod to the valve shaft, thereby moving the valve shaft up and down; a second link unit connected to the valve main body; and a connection unit which connects the second link unit and the first link unit and transmits a movement of the valve main body in the horizontal direction to the first link unit through the second link unit.

    Abstract: A valve for regulating the temperature of an oil flow, includes a first inlet channel, a second inlet channel and an outlet channel, the second inlet channel and the outlet channel being capable of cooperating with a temperature regulator. One of the inlet channels includes an oil flow regulator controlled by a computer by generation of an electrical set value respecting a control law configured within the computer, the control law being slaved by an oil flow temperature sensor, the electrical set value controlling opening and closing of the regulator, the regulation law generating an alternation of open and closed states of the flow regulator so as to achieve a required average temperature of the oil flow over a given period.

    Abstract: An apparatus for controlling an aeroplane gas turbine engine has various sensors and devices for operating the engine, and two control channels each calculating a command value for controlling operation of the engine based on signals outputted from the sensors. In each of the control channels, it is determined whether any of the sensors and devices is abnormal based on the signals to determine a failure level of the control channel concerned with a numerical value. The failure level is compared with that of the other control channel and based thereon, the command value calculated by the control channel of smaller failure level is sent to the devices. With this, even when both control channels are failed, the engine control can be continued with taking the failure level into account.
