Comparison research on the anemometer system of wind power generation

介绍了机械式测风传感器与超声波测风传感器的工作原理,比较了它们的特点,及对风力发电的影响。分别对装有2类测风传感器的风力发电机组进行了运行分析,得出2类测风传感器对应的机组功率曲线增长率。试验结果表明:超声波测风传感器进行风速、风向测量更有利于提高风力发电机组的利用率与稳定性。

Introduces the work principle of mechanical wind speed sensor and ultrasonic wind speed sensor, compares their characteristic and the influence of them on the wind power generation, analyzes the operation status of wind power generation units to install two kinds of wind speed sensor, draws the ＇power increase rate curve of the wind power generation units＇ with two kinds of wind speed sensor. The test result shows that using ultrasonic wind speed sensor make the wind speed and direc- tion measurement more beneficial to improve the availability and stability of the wind power genera- tion units.
