Abstract

PURPOSE: To increase an operating ratio by controlling respective a plurality of auxiliary equipments with the same functions in the same plural auxiliary equipment system among a plurality of systems, in which one of auxiliary equipments is equipped later, by different programmable controllers PC.
CONSTITUTION: In a thermal power plant, etc., auxiliary equipment systems No.1WNo.4 have auxiliary equipments AUM1AWAUM4A, AUM1BWAUM4B, and AUM1CWAUM4B having the same functions; auxiliary equipment AUMs 1AW4A and 1BW4B are normal in operation and auxiliary equipment AUMs 1CW 4C are controlled as equipments to be equipped later by PC3WPC4, respectively. If PC3 runs into trouble, auxiliary equipment AUMs 1AW4A getting beyond control in respective auxiliary equipment systems are stopped and auxiliary equipment AUMs 1CW4C are actuated by an interlock added to sequence control. Thus, the auxiliary equipment in respective systems can be put continuously in automatic operation without deteriorating their functions, increasing the operating ratio.
