Validating anti surge control systems

In addition, a model structure for gas turbine, which can be used as compressor governor, has been proposed.

Bush’s Presidency began in the shadow of a contested and likely stolen election and promised to be unsuccessful in a largely forgettable and unremarkable way.This research focuses on developing and validating a physics-based, modular, non-linear and one-dimensional dynamic model of a compression system: centrifugal compressor and its surrounding process equipment like scrubber, cooler, a recycle line with a control valve and check valve.The mathematical approach of the model is based on laws of conservation and the included ordinary differential equations (ODEs) which describe the system dynamics, is solved by using advanced computational method in an in-house FORTRAN code. 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 suggested to evaluate control performance and power consumption of the compression system.
