Autonav has just commissioned the first of 18 Tidal Energy systems for Big Moon Canada. Each system used two 850 kNm steering systems to operate accelerator plates (rudders) over 90 degrees, which control the flow of tidal current into the electrical generator. The PLC control system allows local and remote control of the equipment status and power generation. A duplicated control and power system is backed up with a DC emergency control. Variable Frequency Pump Drive is used to minimize power consumption and noise while maximizing operating life. With this unique design, all equipment is barge mounted for easy access and maintenance.
