摘要

A turbo generator designed specifically to replace pressure reducing valves (PRVs) in water distribution networks has been developed by Zeropex AS of Norway. The unit, known as the Difgen, consists of three major components: a turbine, a generator and variable frequency drives. The units use a rotary lobe turbine with a twisted lobe arrangement, so that pulsing and water-hammer is mitigated. It is controlled by a system incorporating upstream and downstream pressure sensors, which continuously feed information to the control, to maintain the desired downstream pressure. The output is kept to mains parameters through twin variable frequency drives.
