METHOD, DEVICE AND DATA SET (VERSIONS) FOR COMPRESSOR UNIT CONTROL Russian patent published in 2015 - IPC F04C28/02 F04B49/06 

FIELD: machine building.

SUBSTANCE: invention relates to the method of compressor unit control, to a control unit, and also to a data set for compressor unit control. In the method of control of the compressor unit (1) which comprises several compressors (2), meanwhile by means of the unit (1) in the compressed fluid medium system the pre-set excessive pressure shall be supported, and at regular fixed or variable time intervals the decisions on switching actions for the system adaptation to the actual conditions are made. At the pre-selection step the alternatives of switch-overs from a large number combinatorially available alternatives of switch-overs are excluded. At the main selection step the remained alternatives of switch-overs are estimated with reference to each other using one or several criteria of optimisation and the optimum for pre-set criteria alternative of switch-overs is selected. At the control step the selected alternative of switch-overs is output for execution in the unit (1).

EFFECT: invention is aimed at creation of the control method providing sufficient supply of compressed fluid medium even at its unstable intake from the compressor unit, meanwhile the switch-overs simultaneously induced by the control system shall be performed in a cost-efficient way.
