  • Enhanced method of controlling the output of a hydroelectric turbine generator
    Patent number: 8872371
    Abstract: There is described a method for controlling the output of a tidal hydroelectric turbine generator from a remote location, with the need for control circuitry to be housed local to the generator. The rotational speed of the turbine, and consequently the output power level of the generator, is controlled by varying the transmission line voltage of the submarine power cable connecting the off-shore turbine with an on-shore substation.
