Patent ID: 8890351

Claim:
An electricity producing installation including a plurality of electricity producing devices at least partly immersed in water, capable of transforming mechanical energy provided by a stream flow into electric energy, each electricity producing device comprising a rotary mechanical receiver able to set into rotation by the flow stream and an alternator comprising at least one rotor and at least one stator, the at least one rotor of the alternator being able to be set into rotation by the rotary mechanical receiver, wherein each electricity producing device produces an electric AC signal with variable voltage and frequency conveyed by an at least partly immersed electric transport cable, the installation further comprising: an interconnection device to which are connected at an input, in parallel, the electric transport cables stemming from each electricity producing device, and which provides at an output a joint electric signal, said joint electric signal being an electric AC signal with variable frequency and voltage, the current amplitude of which is equal to the sum of input currents; and a partly immersed export cable connecting the output of the interconnection device to a power conversion device out of the water, said power conversion device being capable of transforming the joint electric signal into an alternating electric signal with a set frequency intended for an electricity distribution or transport network.
