Electrical control of gas turbines in gas transmission service

BY THE installation of new pipe lines and additional power the gas transmission industry continues to supply a greater percentage of the United States' fuel requirements. The newest type of plant for this service is the gas-turbine-driven direct-connected centrifugal compressor. This paper describes the electrical control for gas-turbine compressor stations on the Texas Eastern-Penn Jersey pipe line. Fig. 1 shows the Perulack station as built for one gas-turbine compressor unit.
