Control of compressor with variable speed and variable exit guide vanes

摘要

A compressor (CO) is driven by a variable speed drive (VSD) and comprises a variable outlet guide vane diffuser (VD). As long as the guide vanes are not fully open, the compressor is controlled mainly by adjusting the guide vanes and adapting the speed to the vane position. When the guide vanes are fully open, the compressor is controlled by adjusting the speed only.
