2. The application of optical fiber in solar energy

In a solar farm power generation system, solar heat generates a lot of current. In order to protect equipment from huge current leakage, electrical insulation is essential to ensure the quality and reliability of the power system. Optical fiber can provide insulation protection to prevent high voltage or current interference.

The key applications of fiber optic components in solar systems include:

1 Power electronic gate driver for inverter

2 Solar tracking control and communication board

3 Substation automation and protection relays for solar power plants

Figure 1 Solar power generation frame Solar panels collect solar energy and convert it into electrical energy through photovoltaic modules or solar collectors. In order to integrate the electricity generated by the solar panels into the transmission line, the electricity needs to be converted into utility-grade alternating current 

Examples of power semiconductor devices available on the market:                                 

1 Insulated gate bipolar transistor (IGBT)                   2 Delete level power-off thyristor (GTO)        3 Integrated Gate Commutation Thyristor (IGCT)

4 Symmetric Gate Commutation Thyristor (SGCT)   5 Launcher turn-off thyristor (ETO)


Fiber optic tissue is usually used to control high voltage and current switches and current switching devices, and has reliable control and feedback signals (Figure 2, Table 1)
