Abstract: TransCanada PipeLines operates a major natural gas transmission system from the Province of Alberta two thousand miles across Canada to Montreal. This system is shown in Figure 1 and consists of 6,000 miles of pipeline (including loop line) varying from 34 inches to 48 inches in diameter. The western portion of the pipeline has four completely looped lines plus a fifth partially looped line. At Winnipeg two lines continue to the east through Ontario and two lines are directed south to Minnesota, where gas is delivered to Great Lakes Gas Transmission Company which is 50% owned by TransCanada. Forty-nine compressor stations are located at regular intervals along the pipeline to keep the gas moving to the major markets in the east. Compression facilities at these stations total over 1,224,000 installed horsepower. The secure and efficient operation of these facilities, particularly in the light of increasing energy costs, produces a need for the most effective control possible at each compressor station and at the gas control dispatch centre.
