Tallest mast for wind measurement fully operational
Ecofys completes construction of 120 meter mast at Test Site Lelystad in the Netherlands
Utrecht, The Netherlands, 03 September 2013 – The construction of a 120 meter mast for wind measurements at Test Site Lelystad has been completed by Ecofys Wind Turbine Testing Services (WTTS). The met mast is the tallest mast of its kind in Northwest Europe to date and will deliver meteorological data for testing wind turbine prototypes. Ecofys WTTS performed the design, contracting and installation of the mast which has been erected ahead of schedule in August 2013.
With hub heights of wind turbines increasing, wind shear information at increasing heights is required. The new met mast is fully equipped with instrumentation at four heights (40, 80, 95, 120 meters) to provide verification testing services for remote sensing devices like SoDARs (Sonic Detection And Ranging) and LiDARs (Light Detection and Ranging). For this purpose, a special test-pad has been designed and installed next to the mast, enabling safe, plug-and-play installation and power and network connection feeds to install up to ten remote sensing machines in parallel. In early August, the first set of new machines has already been installed for verification on site.
Michiel Müller, Unit Director Wind Energy at Ecofys, explains: “By now, remote sensing technology like LiDARs and SoDARs are fully accepted to assess wind resources and to verify power curves. A high quality verification of these measurement devices is essential. This new extra tall and fully equipped mast provides those means and allows wind project developers and owners to take full advantage of this next innovative step in technology.”
