The precision generator set is a device required to be capable of step changes in electrical output from no-load to full-load almost instantaneously with essentially no change in frequency. As a result of the time required for a conventional turbocharger to respond to a load change, the precision generator set application has been the exclusive realm of relatively large naturally-aspirated engines, despite the potential weight and fuel consumption advantages of smaller, turbocharged units. The advent of variable turbine geometry for small, inexpensive turbochargers may provide the means by which turbocharged engines may enter into this specialized service. This paper describes the application of variable geometry turbocharging to the precision generator set from the feasibility study to the proof-of-concept as verified in the standard test series for such a generator set.
