Abstract:
As for the
fixed hydraulic-secondary-control-system, a project of only using
three-phrase induction machine to drive the secondary system is
presented, so that the restriction of recycling energy within the
hydraulic-secondary-control-system is broken through. This project is
simple and excellent, which can put electric
network-hydraulic-secondary-control-system into running reversibly, and
widen the range of recycling energy from mechanical-hydraulic-system to
electric-hydraulic-me- chanical-system, so that the advantage of saving
energy of secondary control system is made the most of. The stability
and security of system, especially the question of induction machine-
constant pressure variable pump/motor running reversibly in second
quadrant is analyzed. The feasibility of this project is proved.
Key words:Secondary
