风电机组风速风向仪未来发展趋势研究

摘要

Wind direction and wind speed sensor is the most important element of wind turbine, its working characteristics are directly related to the control strategy and power efciency of fan. In this paper, through the analysis and comparison of the wind turbine mechanical, traditional principle of ultrasonic and ultrasonic resonance wind instrument structure and the advantages and disadvantages, ultrasonic resonance type wind instrument with long service life, high practicability, compact and light and excellent sensitivity and accuracy, will gradually replace the mechanical and the traditional ultrasonic wind anemometer in the future.%风速风向仪是风电机组最重要的传感元件，它的工作特性直接关系到风电机组的控制策略和发电效率。本文通过对风电机组机械式、传统超声波式和超声波共振式风速风向仪结构原理和优缺点的对比分析，超声波共振式风向风速仪因寿命长、实用性高、小而轻的结构及出色的灵敏度和准确性，必将在未来的发展竞争中逐步取代机械式和传统超声波式风向风速仪。
