Abstract

In this paper, the model of centrifugal compressor driven by turbine is built up. Comparing with the centrifugal compressor driven by motor which has the steady speed, system in this paper can be governed not only by anti-surge valve but also by speed of turbine. The purpose of this paper is system simulation and to design PID controller governing this system to meet the needs of the pressure ratio and anti-surge. Anti-surge valve will open if the operation point of centrifugal compressor is close to the surge line. Furthermore, we design two PID controllers which made system become stable quickly and compressor not work in surge area, one of the two governing the speed of turbine and compressor and the other one governing the anti-surge valve.
