摘要
在风能发电中,风速风向仪对系统有着极其重要的作用。本文介绍了时差法测量风速风向的原理。与传统设计不同的是,系统设计了基于低压驱动探头的驱动电路,降低了成本,减少系统因高压带来的干扰。在信号调理模块中,采用了集成低噪声放大器和滤波器。实验结果验证,各个模块的设计均符合系统的要求。
In wind power generation,the instrument of wind speed and direction has an important role in the system.The principle of the time difference method measuring the speed and direction of wind is introduced.With the traditional design,this system designed the driving circuit based on the lowvoltage drive,reduced the costs and interference because of the high voltage drive.In signal disposal module,used the integrated circuit of low noise amplifier and filter.The experimental results showthat each module design conforms to the requirement.
