Abstract: An instruction terminal includes a storage that stores correspondence information that associates, for each of communication devices, identification information of the communication device and candidate parameters for communication with the communication device, a first instructor that issues an instruction to acquire the identification information of a network device that is a communication device of the communication devices and is connected to a communication apparatus via a network, a second instructor that issues an instruction to specify, from among candidate parameters that are included in the correspondence information and correspond to the identification information, a device parameter for the communication with the network device, and a receiver that receives specification information indicating the specified device parameter.

Abstract: There is provided a method including: performing an upgrade of reducing a supply amount of cooling air supplied to a turbine and replacing at least some of components provided in the turbine with components adapted to the supply amount of cooling air; and changing a set value calculation function according to the post-upgrade supply amount of cooling air and the replaced components.

Abstract: A combustor replacement method and a gas turbine plant capable of efficiently replacing a combustor using an existing facility. The combustor replacement method includes a step of separating, from a plurality of fuel supply systems, a first combustor that includes a plurality of nozzle systems connected to any of the plurality of fuel supply systems and supplied with fuel from the connected fuel supply systems, and removing the first combustor from a gas turbine plant. The method includes a step of attaching a second combustor that includes fewer nozzle systems than the first combustor to the gas turbine plant, and a step of providing communication between the fuel supply systems connected to the same nozzle system of the second combustor by a coupling pipe, and coupling the fuel supply systems and the second combustor.
