Abstract

PURPOSE: To carry out all control for steam turbine required in starting operation, increasing load and disconnecting the load, by controlling an intercept valve by use of a lower one of the outputs from a main speed governor and a pre-emergency governor selected by a lower-value preferring means.
CONSTITUTION: In starting turbine operation, steam control valve 3 and intercept valve 6 are opened almost simultaneously so that steam is passed therethrough at an equal flow rate or at a constant rate. At the time instant when turbine by-pass operation is terminated after turbine load is increased, intercept valve 6 is fully opened and turbine operation is controlled only by steam control valve 3. On the other hand, when revolutional speed of turbine is increased, for instance, at time of disconnecting load, intercept valve 6 is closed by the function of pre-emergency governor 14.
