The main applications of industrial optical fiber in wind power generation systems include power electronic gate drives for rectifiers and inverters, control and communication circuit boards, wind turbine control units, condition monitoring systems, and wind farm networking.

Wind turbine power generation

Wind turbines use generators to convert kinetic energy into electric energy. As wind conditions change, the electricity generated by the generators must be converted before they can be used. Wind turbines must have rectifiers, inverters, transformers and filters. Wait for the equipment so that the generated practical AC power can be transmitted over a long distance, as shown in the figure below.

Transformer equipment is usually installed at the bottom of the wind power tower to convert the low voltage generated by the wind turbine into a medium to high voltage that is convenient for transmission.

Utility Grade AC Power = Utility Grade AC Power

Rectifier and inverter

Rectifiers and inverters are the main components of wind turbine systems. Rectifiers can convert high-noise AC power into DC power, while inverters can convert DC power into clean and reliable AC power output. The switching actions of these devices are usually embedded Digital signal processor (DSP) is controlled by optical fiber link to provide high efficiency and reliable control with high electrical insulation capability.

Basically, there are several options for the control switch of the rectifier and the inverter, namely, insulated gate bipolar transistor (IGBT), gate turn off thyristor (GTO, Gate Turn Off Thyristor), and integrated gate. Integrated Gate Commutated Thyristor (IGCT), Symmetrical Gate Commutated Thyristor (SGCT), Emitter Turn-off Thyristor (ETO), etc.

Fiber optic components are commonly used to control high voltage and current switching equipment to provide reliable control and feedback signals. Please refer to the figure below.
