Abstract

PURPOSE: To meet the requirements of a steam turbine system for quick response by constituting the load setting device therefor such that it allows quick change of a load setting signal thereto to a degree.
CONSTITUTION: When a first lower value selection circuit 43 provides an output which is equal in value to an output of an amplifier 42, a second lower value selction circuit 46 provides a load signal S which is thus equal to the output of the amplifier 42. If the load setting signal is quickly changed to be a value L2, the output of the second lower value selection circuit 46 at first follows the load setting signal until the load setting signal reaches a value Ln determined by a load change width limit setting signal, and it thereafter increases up to the value L2 as the output of the first lower value selection circuit 43 increases up to the value L2at a fisced ratio determined by a load increase ratio signal whereafter it is held at the value L2. By such constitution, the requirements of the system for quick response are met, and a load setting can be effected without having any ill effect on the mechanical durability of the turbine and so on.
