Application of a 15000-HP, 6000-r/min adjustable-speed drive in a petrochemical facility

The improved reliability of power electronics and the development of motors capable of operating directly at high speeds have made electric motors a viable alternative to steam turbines in process plants. This paper discusses the application of a large high-speed, adjustable-speed synchronous motor with a load commutated inverter as a recycle compressor driver in a petrochemical facility.
