<p>A plurality of dc output generators 2 are positioned on the seabed such that, when a tidal current flows, turbines of the generators are caused to turn and this motion is employed for the generation of dc power. The outputs of the generators are connected in series to produce a summed voltage that it greater than the output voltage of each generator. A tidal energy farm 1 may, for example, comprise a matrix of twenty-five such generators, arranged in five strings A to E, each string comprising five generators connected electrically in series. Each generator may be a 2.5MW generator, generating a maximum voltage of 5Kv at a maximum current of 500 amps. The outputs of all of the strings A to E are connected in parallel to a positive output cable 3 and a negative output cable 4. Thus, the maximum output power on the cables 3 and 4 is 25 Kv at 2500 amps - that is, a total of 62.5 MW.</p> |
