METHOD FOR IDENTIFYING THE SURGE LIMIT OF A COMPRESSOR

摘要

A method for identifying a surge limit of a compressor. The compressor is driven at least by an electric motor, the power of which is regulated by means of a regulation device. The regulation device detects regulation activity during the operation of the compressor. A surge limit of the compressor is identified if the regulation activity or a change in the regulation activity overshoots a threshold value which is assigned to the surge limit.
