RTE installs the first submarine cable for the Fécamp wind farm

Posted on 27 / 09 / 2021 lemarin

The installation of the first submarine connection cable for the Hautes Falaises wind farm, off the coast of Fécamp, began on September 26 at the entrance to the Norman port. It is the second installed in France and the first in the region.

The operations to bury this first of the two 225 volt cables, which will connect the electrical substation at sea to the land network, should last between three and four weeks, indicates in its press release RTE, in charge of the connection. The cable will be buried 000 meter deep and 1 km long by the cable company Cable Enterprise, from the Italian group Prysmian, a service provider chosen by the operator of the French electricity network. The second cable will be installed before the end of the year.

The commissioning of this park, which will consist of 71 wind turbines with a unit capacity of 7 MW, is scheduled for 2023. The delivery and laying of the offshore foundations, currently under construction in Le Havre on the Bougainville quay, is announced. for summer 2022.

We are far from the 6000MW by 2020 of the title....
However, the St Brieuc park is in the process of being commissioned and that of Fécamp is setting up its first machines.
Come on, for the winter, we should have close to 1500MW installed, including the St Nazaire park which is already in service.
It's not that simple....

F. Bouglé is a relentless anti-wind turbine, he even wrote a book on the subject. It is therefore not surprising that he is delighted with the current difficulties in the sector.
Technical difficulties at Siemens for sure, but I understood that it would only concern onshore wind turbines. But despite everything, a bad course to pass
Financial difficulties elsewhere, with other manufacturers. Probably partly linked to a certain "price war" between manufacturers to grab offshore projects which despite everything are not as numerous as that, even on the scale of Europe.

Without permanent magnets, part of the energy produced must be used to power the inductor, resulting in a loss of efficiency https://imamagnets.com/fr/blog/aimants- ... -eolienne/

not necessarily.

This also makes it possible to better control the machines by adjusting the rotor magnetic field.

It's a thing of the past, today's electronics are capable of producing at any speed in direct transmission. No more gear boxes...
“It's a simple technology, summarizes the engineer. The permanent magnets that equip the rotor of the generator induce a magnetic field which, crossing copper coils, generates an alternating electric current. By using a very large number of permanent magnets, synchronous alternators generate as much energy as asynchronous generators, which are subject to the slip phenomenon. Moreover, the magnetic field being spontaneously issued from the magnets, this type of generator offers the advantage of dispensing with a rotor power supply system, which represents a gain in weight and energy.
