Compressor Operation Monitoring and Optimization Method for Large-scale Natural Gas Pipelines

Abstract

Abstract The monitoring of large-scale natural gas pipelines is vital to their reliable and effective operation. To the lack of data analysis and operation advice functions in existing monitoring systems, this work established a pipeline monitoring system. The pipeline working state was uncovered with data reconciliation and thermodynamical models. Temporal load distribution was depicted for operation monitoring. Based on historical data, operation advice for working compressor numbers and outlet pressure of each station was generated by the system. Deployed on a practical pipeline, the software architecture of the system was introduced. Tested with field data, the system showed good performance on data analysis and operation advising.
