UNDERWATER POWER STATION AND METHOD FOR OPERATING AN UNDERWATER POWER STATION

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.
