Modeling of Surge in Free-Spool Centrifugal Compressors: Experimental Validation
The derivation of a compressor characteristic, and the experimental validation of a dynamic model for a variable speed centrifugal compressor using this characteristic, are presented. The dynamic compressor model of Fink et al. is used, and a variable speed compressor characteristic is derived by the use of energy transfer and loss analysis. It is demonstrated that taking into account the losse...
متن کاملSupercritical fluid recycle for surge control of CO2 centrifugal compressors
This paper presents computer-based design and analysis of control systems for centrifugal compressors when the operating fluid is supercritical CO2. It reports a non-linear dynamic model including a main forward compression line and two different configurations for the recycle antisurge line. Disturbance scenarios are proposed for testing the configurations and performance indicators are sugges...
متن کاملDrive torque actuation in active surge control of centrifugal compressors
A novel aproach to active surge control is presented for a centrifugal compressor driven by an electrical motor. The main idea of the paper is to use the drive itself for surge control. This eliminates the need for additional actuators, and has the potential of energy efficient operation. It is shown that previous unstable operating points to the left of the surge line can be made globally expo...
متن کاملActive surge control of centrifugal compressors using drive torque
A novel aproach to active surge control is presented. A centrifugal compressor driven by an electrical motor is studied, and the drive itself is used for surge control, thus elliminating the need for additional actuators. It is shown that by using the rotational speed of the motor as control, previous unstable operating points to the left of the surge line can be made globally exponentially sta...
متن کاملA New Engineering Method for Fuzzy Reliability Analysis of Surge Detection and Isolation in Centrifugal Compressor
A new dual fuzzy controller for the nonlinear model of the compression system is proposed in this paper. The surge phenomenon in the centrifugal compressor, the non-linearities and uncertainties of the compression system make it impossible to use a conventional controller over a wide range of operation. This fuzzy controller is designed to consist of a active surge control and phase control wit...
