“…Electric drivers are able to manipulate the driver torque within hundreds of milliseconds, whereas gas turbines are much slower mainly due to thermal stress limitations. This advantage can be used for enhancing surge avoidance [6], but traditional anti-surge control approaches are not capable of hosting such a functionality.…”

“…Furthermore, compressors are assumed to be among the major energy consumers in many industrial processes such as air separation [1]. Consequently, optimal operation of compressors is of considerable interest [2], [3], [4]. The available studies have considered different applications, such as natural and supply gas systems, and different system setups, such as fixed-speed drivers, variablespeed dual-shaft gas turbines and variable-speed electrical drivers [2].…”

Abstract-We discuss optimal load sharing of parallel gas compressors in the presence of plant-model mismatch. We formulate this problem as a static real-time optimization task and propose to tackle it by means of modifier adaptation. Under mild assumptions, the chosen approach guarantees optimal operating conditions upon convergence. Furthermore, we discuss how the specific problem structure can be exploited to estimate the plant gradients efficiently during process operation. Finally, we draw upon simulated case studies for two and six compressors to demonstrate the applicability and effectiveness of the proposed real-time optimization approach.

“…However, less research has been done on compressor modeling, in a gas pressure boost system to control anti-surge, along with its lateral elements. In [4] this subject is considered by presenting a model based on state equations. In this paper, we have presented a model based on artificial neural networks and compared our results with the reported results in [5].…”

To prevent the destructive surge phenomenon in centrifugal compressors, we usually choose the surge control line in a prudent manner, which in turn cause in reducing the efficiency of compressor and results in increasing energy consumption of its actuator. It requires a roughly accurate model of system performance to design an optimum controller. In this paper we introduce a model based on artificial neural networks. It gets the compressor RPM, anti-surge valve state, temperatures, compressor gas output flow rate and its upstream pressure as inputs. We have used the measurements conducted by cybernetics laboratory of Norway University from a centrifugal compressor installed in a gas processing plant as our dataset. We have achieved better results in predicting the system output in comparison to mathematical model based on state equations.
