Secondary control is an energy-saving drive concept with high dynamics for the installation of rotational speed, position, or torque controls with energy recovery. Hydrostatic energy transfer with secondary control means controlling the torque directly at the secondary unit. The required volumetric flow rate is taken directly from a hydraulic pressure system with an impressed operating pressure. The primary side prevents drops in pressure. By integrating hydraulic accumulators, potential or kinetic energy from the consumers can be recovered here.
Dégra has integrated secondary control systems in offshore solutions. Looking for a secondary control system? We look forward to meeting you.
