Optimizing fuel savings at the TransCanada compressor stations
To minimize compressor-station fuel consumption, TransCanada PipeLines uses minicomputers to optimize work-load distributions at 10 compressor stations serving four 34 to 42 in.-diameter parallel pipelines at the western end of its 3000-mile, Alberta-to-Quebec transmission network. The computer optimization program consists of (1) a pattern search routine that seeks the most efficient flow distribution among the available units and (2) a mathematical model that predicts the fuel consumption of a compressor unit for a given pressure and head. During normal operation, the computer adjusts load-sharing values every 15 minutes to respond to normal changes in station head and flow. Unlike manual load balancing based on the rated horsepower of compressors, computerized optimization considers the efficiency of each unit, resulting in a 1 to 2% fuel saving that pays for the computer system in only 3 to 4 years.
