Abstract
A fluid compression system includes a gaseous fluid compressor having a fluid inlet and a compressed fluid discharge, a prime mover coupled to the gaseous fluid compressor in driving relation, and a demand sensor positioned to measure a compressor demand and output a demand signal. An engine control unit is coupled to the prime mover and is operable to measure prime mover speed and prime mover power output. The engine control unit sets a variable maximum rated speed that maintains the engine power below a predetermined limit. A compressor controller unit is arranged to receive the demand signal and vary an operating speed based in part upon the demand signal. The operating speed is limited to the maximum rated speed set by the engine control unit.
