Application of a 5500 RPM high speed induction motor and drive in a 7000 HP natural gas compressor installation

The reasons for the selection, and considerations in the implementation, of high-speed induction motors and variable-frequency drives for a compressor station in an unmanned installation on a gas pipeline are presented. The selection options relevant to the application are reviewed: gas turbine versus motor driver, high-speed motor versus conventional motor, and induction versus synchronous motor. Design features of the major system components are discussed, including the power system, compressor, motor, and variable-frequency drive. Testing and commissioning results are described.<
