FEATURE SPONSOR ADVANCES IN REMOTE SENSING & MONITORING


The output power and cost effectiveness of wind turbines is crucial, as windfarms are financed on the basis of a return on investment. This is strongly influenced by the amount of wind available and calculations are based over a prolonged period of time to determine on how much wind is available all year round. Any errors in these predictions can have an enormous effect on the output power and viability of any site. Therefore, accurate wind profiling, optimising efficiency and reducing maintenance are critical to the success of wind energy installations.


COMPREHENSIVE AND ACCURATE WIND PROFILE


To calculate wind in the area, large profiling towers are erected with anemometers mounted at varying height. Gill 3D WindMaster’s have been networked into numerous sites to provide a comprehensive and accurate profile of the wind. The sensors profile wind within the site record data on horizontal and vertical wind components and the data is used to calculate whether a proposed site is suitable for wind energy generation. The company’s anemometers offer high data output rates of up to 32Hz, which is validated via an automatic data quality message so users can have confidence that the data can be trusted.


Maximising the output power from turbines is extremely important to the efficiency of windfarms, so ensuring turbines are facing into the direction of the wind maximises efficiency. Gill 2-axis anemometers (WindSonic, WindObserver) are usually installed on the nacelle and perform a key control function in positioning the nose cone. Data from the anemometer helps direct the turbine into the wind and verifies the efficiency output of the turbine relative to the wind conditions.


CHALLENGING ENVIRONMENTS Onshore and offshore wind energy locations can be challenging environments so Gill anemometers are tough and reliable with little or no maintenance. The solid- state designs achieve a longer service life than mechanical instruments and with no recalibration required, which reduces downtime and maintenance costs.


The products are extensively chosen for projects in the wind energy market due to their high reputation for quality, easy installation and confidence that the data will help improve the efficiency.
