Abstract (en)
[origin: EP3293364A1] In the present invention, a turbine control panel (TCP) (57) performs a pressure-changing operation wherein the pressure of steam introduced into a steam turbine is changed. In addition, a load capacity value calculation unit (70) with which the TCP (57) is provided calculates the actual load capacity value obtained from the steam turbine on the basis of the deviation between a target degree of opening of a speed adjustment valve and the actual degree of opening of the speed adjustment valve, and controls the degree of opening of the speed adjustment valve on the basis of the calculated load capacity value. Thus, the TCP (57) does not use a pulse signal, as in the prior art, to change the load capacity value used in controlling the degree of opening of the speed adjustment valve, so the speed adjustment valve can be controlled without the occurrence of a time lag that is typical of a pulse signal.
