摘要： In a sealing device which seals between an outside space between an outer side in the radial direction of an external diffuser which has a tubular shape and forms an exhaust channel through which combustion gas rotating a rotor of a gas turbine passes in the inner side in the radial direction and an outside member which is disposed outside the external diffuser with an interval between them in the radial direction, and the exhaust channel by an end of the external diffuser, a first seal plate group and a second seal plate group in which a plurality of seal plates, which extend to the outer side in the radial direction from the end of the tubular external diffuser and reach the outside member, are laminated in contact with each other, and a spacer which maintains the first seal plate group and the second seal plate group with an interval in an axial direction in which a rotational axis of the rotor extends are provided.

IPC分类号： G05B19/418
摘要： A control parameter optimization device is provided with: a plant model configured to calculate a control command value by a control device and a process quantity of a plant; a control parameter updating unit configured to update a control parameter used for calculating the control command value in the plant model, on the basis of an objective function calculated based on a calculation result of the process quantity in the plant model; and a structural model configured to calculate a clearance between a stationary member and a rotating member in the rotating machine, on the basis of the process quantity from the plant model. The control parameter updating unit is configured to search for an optimal control parameter within a range where the clearance calculated by the structural model satisfies a constraint condition.
