Abstract

To meet the basic requirements of performance regulation for centrifugal compressors

the coupling effect between performance regulation and anti-surge control under different operation conditions of the compressor were deeply analyzed. A control strategy for decoupling the performance controller was proposed based on conditions such as the compressor's working point and load increase/decrease. Additionally

by adopting the quasi-nonlinear modeling method

the compressor system and control models were developed

which could be solved in real time on a unified platform. Model solving was conducted via a multidisciplinary simulation platform

yielding the compressor's dynamic characteristics under variable conditions and verifying the control effects of the performance control and decoupling strategy. Results show that the proposed method achieves performance control

realizing the design concept of prioritizing anti-surge valve closure during load increase and rotational speed reduction during load decrease

ensuring stable unit operation when the compressor runs under variable loads.
