Title:
APPARATUS FOR RATIONALLY SELECTING CONTROL MODE FOR STEAM TURBINE POWER PLANT
Document Type and Number:
Japanese Patent JPS54138936
Kind Code:
A
Abstract:
A system for intelligently governing the selection of one of a boiler follow or turbine follow mode of control of a steam turbine power plant is disclosed. Boiler and turbine master controllers are concurrently operative in one of the boiler follow and turbine follow modes for controlling the firing rate of the plant boiler or positioning the steam admission valves of the steam turbine, respectively. Each of the boiler and turbine master controllers are operative to respectively generate a first and second plurality of signals which are representative of plant control status. A selecting means is disposed as an integral part of the plant controls for switching between the turbine follow and boiler follow control modes. Accordingly, the disclosed system intelligently governs the selecting means to switch the plant control to the boiler follow mode in accordance with a first set of predetermined plant control conditions and to switch the plant control to the turbine follow mode in accordance with a second set of predetermined plant control conditions wherein the first and second sets of predetermined plant control conditions are established from the first and second plurality of signals.
