光纤通信在风力发电系统中的应用

Application of Optical Fiber Communication in Wind Energy Conversion System

光纤通信具有传输距离远、速度快以及抗干扰能力强等特点。针对风电场环境恶劣和电磁干扰大的特点,以及风机控制系统对实时数据的远距离高速稳定传输的要求,将光纤通信应用于大功率风力发电控制系统中。针对国产PLC项目开发的实际情况,详细介绍了基于STM32平台光纤通信的实现。通过现场调试分析,验证了系统数据传输的实时性、可靠性,很好地满足了风机控制系统的要求。

There are several key advantages for using fiber optics in communication, such as long transmission distance, high speed. According to the harsh environment and strong electromagnetic interference of the wind farm, and the requirements for real-time data transmission of long-distance, high-speed and stability of wind turbine control system, optical fiber is used in the communication of high-power wind power control system. In this paper, according to the actual situation of domestic PLC project development, the realization of optical fiber communication based on STM32 platform is introduced. Through on-site testing analysis, the reliability of data transmission system has been validated, and it meets the control system requirements well.
