摘要
根据风力发电系统的应用要求,设计了一种基于ZigBee通信方式的超声波风速风向仪。介绍了时差法超声波风速风向仪的基本原理,以数字信号处理器TMS320F28335为数据处理单元实现风速风向信号的计算;采用无线通信模块CC2530实现与数据处理单元之间的RS-232方式通信和与风力发电控制系统间的无线通信;介绍了采用超声波风速风向仪进行风力发电系统偏航控制的控制原理。实际应用表明:在风力发电系统中,采用无线超声波风速风向仪具有较高的采样精度和灵敏度,且易于安装及维护。
A ultrasonic anemometer based on ZigBee was designed according to the requirement of wind power.The time difference measurement method was introduced,and digital signal processor TMS320F28335 was used to calculate the wind speed and wind direction.The CC2530 was used to communicate with TMS320F2833 through RS-232 and communicate with wind turbine control unit through ZigBee.A control principle was designed for the yawing of the wind turbine by using ultrasonic anemometer.Practical application shows that it’s more convenient for the installation and maintenance of the wireless ultrasonic anemometer,the sample rate and response rate of wind speed and direction are improved by using wireless ultrasonic anemometer in wind power.
