Abstract
In a method for controlling a compression installation (1), the installation has at least two compressor units (i=1, , N) that can be separately turned on or off, a plurality of devices for modifying the output of the compressor units and a control device (10). Known methods and devices do not function optimally in terms of the power consumption of the entire compression installation. The power consumption (EG) for the operation of a plurality of compressor units (i=1, , N) of a compression installation (1) can be optimized by calculating a novel circuit configuration (Si, t) and automatically adjusting the novel circuit configuration (Si, t) by a control device (10).
Claims26
A method for controlling a compressor plant having at least two compressor units, having a plurality of devices for changing the operating output of the compressor units and having a control device, the method comprising the steps of:
- in the event that new set points are predefined or there is a change in the current state of the compressor plant, using an optimization calculation to calculate a new switching configuration from a current switching configuration of the compressor units, with regard to an optimized total energy demand of the compressor plant, and setting the new switching configuration automatically via the control device.
A control device for controlling a compressor plant comprising:
- at least two compressor units having a plurality of devices for changing the operating output of the compressor units,
- an optimization module, with which, in the event that new set points are predefined or there is a change in the current state of the compressor plant, an optimization calculation is used to calculate a new switching configuration from a current switching configuration of the compressor units, with regard to an optimized total energy demand of the compressor plant, and
- an actuating module, with which the new switching configuration can be set automatically.
A computer program product embodied in a computer readable data storage medium, the computer program containing software which when executed on a computer for controlling a compressor plant having at least two compressor units, having a plurality of devices for changing the operating output of the compressor units and having a control device, perform the steps of:
- in the event that new set points are predefined or there is a change in the current state of the compressor plant, using an optimization calculation to calculate a new switching configuration from a current switching configuration of the compressor units, with regard to an optimized total energy demand of the compressor plant, and
- setting the new switching configuration automatically via the control device.
