Effect of Compressor Emergency Shutdown in Various Compressor Station Configurations on Natural Gas Transmission Pipeline

The transient conduct of compressor stations, especially subject to sudden change in conditions, and its effect on performance of natural gas transmission pipeline is one of the most important concerns of operators. The main objective of this paper is to investigate how compressors are arranged in compressor stations, when there is not any standby compressor. Both parallel and series mode have been analyzed for the transient state and it has been determined which of them has more advantages. Considering the boundary conditions in critical conditions, the series arrangement compared to parallel, provides a longer period for the needs of consumers.
