The Alberta Gas Trunk Line’s new 20,000-hp gas turbine compressor set is one of the largest and most modern aircraft derivatives available to industry to date. This paper describes the various aspects of station and unit design for the compressor package. The additional operational flexibility gained as a result of adding this unit to our existing 12,500-hp station is described. The paper will also present a description of the station’s control system, including unit controls, surge controls, and other features of the instrumentation. Trunk Line is concerned with keeping the availability of the unit high, and as such, the paper will describe some features which help keep downtime to a minimum.
