Measuring equipment

Anemometers

Anemometers measure the horizontal wind speed (velocity). This parameter is crucial for any wind site assessment. Cup anemometers are the general standard type of anemometer. They are robust and resistant to turbulence and skew winds caused by masts and traverses. Each anemometer should be individually calibrated and equipped with a certified calibration report according to international standards (e.g. MEASNET). At least two anemometers have to be installed on a met mast. Most anemometers can be equipped with electronically regulated heating.

Studies regarding anemometer behaviour

In order to analyse the accuracy of anemometer and define criterias for anemometer which are suitable for wind measurement the EU has financed three comprehensive studies in which well-known institutes like Risø and DEWI took part. The studies SITEPARIDEN, CLASSCUP and ACCUWIND indicate that the following criterias are crutial for anemometers used in wind measurement:

• Angular response: anemometer behaviour according to variable flow angle
• Turbulence behaviour: anemometer reaction on changing velocity
• Bearing friction: influence of temperature on bearing friction

SITEPARIDEN (2001)

The SITEPARIDEN study describes that different cup anemometer types deliver measurement values that deviate up to 4%. Even calibrated anemometers had huge deviations.

CLASSCUP (2003)

The CLASSCUP study analysed the reasons for the deviations in measurement values in the SITEPARIDEN study. The results are: Angular response, turbulence behaviour and bearing friction. The results of the study lead to a classification systeme which decribes the deviations of cup anemometers. Today the classification systeme is known as standard IEC 61400-12-1.

ACCUWIND (2006)

The ACCUWIND study assessed the accuracy of anemometers on the market. The study indicates that cup anemometer Thies First Class Advance is the the best anemometer worldwide (see table 4-4).

Wind Vanes

Wind vanes determine wind direction. Evaluation of the wind direction enables the best possible positioning of wind turbines. Ammonit wind vanes offer an excellent, fine resolution of 1°, while having very low energy consumption. It is essential that a wind vane covers an entire 360° degree radius, without a north gap. Cheaper wind vanes often have lower quality internal electro-mechanic fittings, which limit their life span, and a considerable north gap. Most wind vanes can be equipped with electronically regulated heating. Digital (TMR) and potentiometric wind vanes are available.

Wind Vanes TMR vs. Wind Vanes POT

With the digital channels of the new Ammonit Meteo-40 data logger, digital wind vanes TMR (Tunnel Magneto Resistance) can easily be connected, i.e. Thies First Class TMR 10-bit serial-synchron and Thies Compact TMR 10-bit serial-synchron. Compared to wind vanes POT, digital wind vanes TMR are the winner on the technical perspective as well as on the commercial point of view. The advantages at a glance: Digital wind vanes TMR ...

• are offered at a lower price than potentiometer wind vanes.
• are subject to less mechanical wear than potentiometer wind vanes thanks to their solid state design. Wind vanes TMR do not have moving parts, except the bearings. Thus digital wind vanes TMR are more reliable and less susceptible to failure.
• deliver more precise measurement values (see table below).

Ultrasonics

Ultrasonic anemometers measure the horizontal wind speed and direction as well as the acoustic virtual temperature. However, because of their high power consumption, a connection to mains power supply is required and their application at self-contained, solar-powered measurement systems is not feasible. Ultrasonics offer excellent performance ratings at well-powered measuring stations. At present they are not accredited according to the internationally valid MEASNET regulations. Ultrasonics are applied for wind park monitoring, on wind turbines and on offshore projects. Most ultrasonic anemometers can be fitted with electronically regulated heating.

Power Supply

Ammonit measuring systems are fully self-contained. A connection to the local power network is not required. The entire measuring system can be reliably powered with a 10 W solar panel. In some cases, larger panel sizes may be required, such as with the application of a large number of sensors when a satellite communication system is applied, or in cold climates requiring sensor heating.

Connection with main Supply

Barometric Pressure Sensors

Barometric pressure sensors (barometers) measure the air pressure. Air pressure and air temperature should be evaluated for an accurate wind site assessment, however, because this data could be obtained from nearby weather stations, they are not considered an essential part of a measuring system. Even so, barometers are worth consideration, taking into account the savings made on the expense of supply, analysis and incorporation of external data over the course of a measuring campaign (at least 12 months). We generally would recommend the inclusion of an air pressure sensor as part of a measuring system.

Impact of measurement errors on AEP calculation

Air pressure as well as air temperature significantly affect the AEP (Annual Energy Production). Hence according to IEC 61400-12-1 air pressure has to be measured in a wind measurement campaign.

Wind power is linear proportional to air pressure. A measurement error of 1% in air pressure induces 1% error on AEP. The standard IEC 61400-12-1 specifies the relations where the sensitivity factor for air pressure in the energy calculation is c_B,i ≈ P_i / 1013 hPa.

Therefore IEC 61400-12-1 requires measuring air pressure and temperature.

Temperature Humidity Sensors

Temperature sensors measure air temperature, while humidity sensors measure air humidity. Both sensors are often applied in combination to reduce cost. The calculation of the air humidity does not directly influence a wind site assessment, but knowing this parameter helps assessing the potential danger of ice build-up at the measuring location. Temperature sensors should always be mounted at a height of at least 10m to ensure sufficient distance from heat radiating from the earth.

Impact of Measurement Errors on AEP Calculation

Temperature and air pressure significantly affect the AEP (Annual Energy Production). Hence, according to IEC 61400-12-1 temperature and air pressure have to be measured in a wind measurement campaign.

Wind power is linear proportional to the invers of temperature 1/T (in Kelvin). At 15°C, 1°C error on temperature measurement induces 0.35% error on AEP. The standard IEC 61400-12-1 specifies the relation where the sensitivity factor for temperature is c_T,i ≈ P_i / 288.15 K.

Therefore IEC 61400-12-1 requires measuring air pressure and temperature.

Show physical background details

The impact of humidity on AEP might be significant if air temperature is high. At sea level and at air temperature of 20°C, air density varies 1.2% between 0 … 100% humidity. It varies 2.0% at 30°C and 4% at 40°C. At high temperatures the IEC recommends to measure the humidity, as well.

Radiation Sensors (Irradiance)

Pyranometers (global radiation sensors) measure global radiation. They are also used as reference instruments due to their measurement precision. The use of this sensor is crucial for measurements with solar-powered applications. It is advisable to use only classified and calibrated pyranometers to ensure accurate results. Adjustable feet and a level allow easy horizontal adjustment.

Specification of Solar irradiance sensors acc. ISO 9060

Pyranometers are classified according to the ISO 9060 standard: "Solar energy - Specification and classification of instruments for measuring hemispherical solar and direct solar radiation". The standard is officially approved by the World Meteorological Organization (WMO). The standard specifies three classes:

• Secondary Standard: Scientific quality and highest accuracy
  Applications: Meteorology (BSRN Network); Testing in PV , CPV and CSP
• First Class: Good quality
  Applications: Measurements for hydrology networks and greenhouse climate control
• Second Class: Medium quality
  Application: Economic solution for routine measurements in weather stations and field testing

Remote Sensing Systems for Wind Measurement

Remote sensing systems have become more and more popular in the wind industry as a supplement to the traditional met mast. Remote sensing systems can be applied to complement a wind site assessment campaign or for wind farm monitoring. The systems measure the wind conditions from the ground up to a height of 200 meters. Thus the wind speed and wind direction up to rotor blade tip-height or for the whole rotor blade area can be used to calculated the wind energy yield forcast. There are two types of remote sensing systems on the market: SODAR (Sonic Detection and Ranging) and LiDAR (Light Detection and Ranging). SODAR instruments measure the wind conditions by means of sound; LiDAR instruments use light to measure the wind characteristics. LiDAR systems can also be installed in top of a wind turbine to measure wind conditions in front and behind the turbine.

Precipitation

Precipitation sensors are designed to measure the quantity and intensity of precipitation striking the earth’s surface. Precipitation is best measured with a tipping bucket device. Precipitation, collected over a surface of 200 cm2, is conducted through an inflow sieve into a tipping bucket. When the bucket has collected 2 cm2 = 0.1 mm of precipitation, it tips over. This measurement principle is based on the “Guide to Meteorological Instruments No 8, WMO”. Precipitation sensors are typically applied for meteorological assessments. This robust device can be equipped with heating when appropriate to the climatic conditions.
