A control device for adjusting an amount of fuel to be supplied to a gas turbine based on a rotational speed of the gas turbine, such that a frequency of electric power output by a power generator that generates electric power using the gas turbine is within a given range, includes a load value acquisition unit configured to acquire a load value that is a value of a load applied to the power generator after cutoff of a part of the load applied to the power generator when the part of the load applied to the power generator is cut off, an arithmetic unit configured to calculate an adjusted value that is a value of the load different from the load value by carrying out an arithmetic operation on the load value and a bias, and a command unit configured to adjust the amount of fuel by outputting a first signal for causing the power generator to output electric power corresponding to the adjusted value.

Control device, control method, and program

A Raman scattered light acquisition device includes an emitting optical system configured to guide excitation light into a fluid, a scattered light window configured to define a part of a flow path of the fluid and through which Raman scattered light from the fluid irradiated with the excitation light passes, and a scattered light receiving device having a light receiving surface receiving Raman scattered light passed through the scattered light window. The scattered light window and the light receiving surface of the scattered light receiving device are disposed at a position in which they are separated from an optical axis in the fluid in a radial direction within a range in which an optical path of the excitation light in the fluid is present in an optical axis direction in which the optical axis in the fluid which is an optical axis of the excitation light in the fluid extends.
