Underwater power station i.e. free-standing power station, operating method, involves fastening turbine to joint connection by spacer element, and causing torque for making pivoting movement by driving turbine using machine in motor mode

摘要

The method involves fastening a turbine (3) to a rotary joint connection (5) of a support structure (1) by a spacer element (4), where the turbine stays in indirect drive connection to an electrical machine (2). The turbine is driven by surrounding water flow during in a generator mode of the electrical machine. The turbine and the spacer element are pivoted at a joint axis from a position (10) into another position (20). A torque is caused for making a pivoting movement by driving the turbine using the electrical machine in a motor mode. An independent claim is also included for an underwater power station comprising a support structure.
