Abstract

PURPOSE: To reduce the consumption of electric power by auxiliaries that are divided into a plurality of groups in accordance with types of input control signals, by connecting a plurality of motors adapted to drive the auxiliaries in each group to the electric power source in the plant via a single frequency converter.
CONSTITUTION: Together with minute flow control by operation of flow regulation valve 11, 11', and damper 16, flows in controlled systems are roughly controlled by speed regulation in accordance with variation of loads of auxiliaries. Of these auxiliaries, those ones that are installed in controlled system where flow control is applied in pursuance to variation of loads, are divided in groups which is regarded central input signal as dividing standard. Plural number of motors to drive auxiliaries as divided in each group is connected to power source in the plant through one unit of frequency changer. Further, each frequency changer is attached central input signal.
