Abstract
Abstract
In recent years the emphasis within British Gas has moved from the construction aspects of the natural gas transmission system to one of investigating methods of optimizing the operational efficiency of the existing pipeline network. In particular, the developments which have taken place in the area of microprocessor technology have provided the opportunity to implement improved control strategies in areas where existing pneumatically based systems are somewhat limited in terms of performance. This paper describes how the simulation software package Simulink was used to evaluate safely the performance of an alternative control strategy whereby the pressure of the pipeline is measured a considerable distance downstream from the main pressure regulating station.
