Parametric analysis of the network elements influence in suction into a compressor on the nature of surge vibrations in the compressor-network system

A mathematical model was developed of a system of the centrifugal compressor joint operation with a network consisting of characteristic elements (pipeline, tank and control valve). It was based on the system elements’ inertia and resistance characteristics. This mathematical model made it possible to compute the system operation (including the dynamic instability modes) in real time or with a set deceleration. A computation program was created on the basis of the mathematical model equations. It was used in parametric analysis of the influence of the network elements size on the surge vibrations nature, amplitude and period of gas pressure vibrations and gas consumption through the network elements.
Keywords: dynamic instability, surge vibrations, centrifugal compressor, compressor-network system
