【Wind Turbine Anemometer Selection Series ①】 Introduction: Four Core Dimensions to Pinpoint the Key Factors in Choosing the "Eyes" of a Wind Turbine

In the field of wind power generation, anemometers serve as the "eyes" of the wind turbine control system. Their performance directly determines the wind alignment accuracy, power generation efficiency, and mechanical load of the turbine. Currently, mainstream single-point wind measurement devices in the market are mainly categorized into three types: cup-and-vane anemometers, ultrasonic anemometers, and propeller-type anemometers. Many wind farm operators and project planners often face the dilemma of "which type is more suitable."

Start with the Core in Selection: Four Key Dimensions to Determine Quality

To choose the right anemometer, it is essential to focus on the actual operational needs of the wind turbine and evaluate four core dimensions. These are the "hard indicators" for determining whether a device is suitable:

Vector Wind Measurement Capability

Whether the device can provide instantaneous, co-sourced, and directionally consistent wind speed and direction information directly affects the accuracy of active control. After all, critical actions such as wind alignment and blade pitching rely on synchronized and precise wind field data.

Wind Direction Stability

In turbulent environments, whether the device can filter out instantaneous fluctuations and deliver stable, reliable "main wind direction" signals is crucial to avoid ineffective turbine actions caused by chasing false wind directions.

Practical Accuracy in Engineering Applications

Beyond theoretical precision in laboratory settings, the real-world significance lies in whether the sensor can help the turbine achieve the combined effect of "maximum power generation + minimum mechanical load" during long-term operation in actual wind fields.

Applicability to Environmental Conditions

Complex operating conditions such as strong turbulence, rain, snow, icing, and thick fog are common in wind farms. Whether the sensor can operate stably under these conditions directly determines its maintenance costs and reliability.

These four dimensions progress step by step, covering the entire process from "data quality" to "practical benefits" and finally to "environmental adaptability."
