 Whether onshore or offshore, optical fiber cables are increasingly being twinned with MV and HV energy cables to provide remote control of rotor speed, blade angle, braking, temperature, hydraulic levels, etc. via distant Programmable Logic Controllers (PLCs) which have now replaced sequential relay circuits for machine control.
24 optical fibers were integrated into the submarine power cable for the Arklow wind turbines off Ireland, 12 optical fibers into the submarine cables for Horns Rev, and 12 optical fibers into the submarine cable linking landbased wind turbines on the island of Smøla (Norway) to the mainland.
