ACTIVE HEAVE COMPENSATION SYSTEM AND METHOD

摘要

An active heave compensation system comprises a motor generator to interact with a load so as to drive the load in a first part of a heave motion cycle and to regenerate at least part of energy with which the load has been driven in a second part of the heave motion cycle, and an electrical storage element for storing the regenerated energy. The active heave compensation system further comprises a power supply electrically connected to the motor generator and the electrical storage element for providing electrical power to at least the motor generator, and a control unit configured to control the power supply substantially in synchronism with the heave motion.

1. A power supply system for a vessel, the power supply system being configured to supply an electrical load, the electrical load exhibiting a load variation, the power supply system comprising:
an electrical storage element for storing electrical energy; a power supply electrically connected to the electrical load and the electrical storage element for providing electrical power to at least the electrical load; and a control unit configured to control the power supply to let an output voltage of the power supply substantially follow, in synchronism with the load variation, a charging and discharging voltage variation of the electrical storage element.
