  • Fiber Optic Communication and Wind Power Principles

    Fiber Optic Communication and Wind Power Principles

    Onshore wind farm fiber optic infrastructures must combine SCADA systems, condition monitoring, energy management and grid integration. Successful wind farms today are highly integrated technical systems whose economic viability depends largely on the quality of their wind energy. Wind energy communication forms the technical backbone of successful onshore wind farms and enables optimal energy yield through intelligent control and continuous monitoring. Owing to several important reasons, the use of Fibre Optic Cables is highly preferred as compared to the former. Fiber optics (FO) technology is probably best known for use in high-speed. Fibre optic rotary joints are replacing electrical slip rings, promising to eliminate one of wind power's most persistent maintenance nightmares. The global wind industry is fiercely battling reliability issues to keep wind turbines turning. From bearings and blades to much smaller, yet critical.
