WindCom - Wind Measuring System

At locations with very complex terrain the results of a computer simulation are frequently faulted, so that these by an at least one year`s Wind measuring and comparative views should be included to measuring data of many years.

Wind Measuring are offered of the WINDCOM as Service.

For this at the location measuring masts are established with the desired and/or necessary height and equipped with anemometer and Data Logger.

For the measurement of the wind velocity to MEASNET calibrated cup anemometers are used.

The recording of the wind direction is takes place by means of potentiometer Wind Vane.

The measured values should be stored out 10-min average values on a Data logger.

The energy yield is charged to the system specific performance characteristic with help on the basis of the 10 min mean average values of the wind speed at the potential location.

The performance of a wind power plant increases approximation wise cubically the wind speed. A measuring error of 5% at the wind speed leads approx. 15% to a fault at the energy yield. It points, how important an exact Wind speed measuring is.

Anemometer
The anemometers should be calibrated before the beginning of the wind measuring. Institutes certified according to DKD (German calibration service) or MEASNET.

The wind direction
Wind direction is usually measured on a height.

Temperature sensor and air pressure sensor (optional)
The flow energy of the wind is proportional to the air density. This is calculated from the temperature and the air pressure. For the improvement in the yield forecast the air temperature and the barometric pressure are therefore often recording.
