Technical Requirements for Rotor Blades Operating in Cold Climate
Wind turbines are increasingly erected at inland sites with their cold climate conditions as the coastal areas are already used for wind energy and offshore projects not yet entered the realisation phase. Furthermore, today's serial produced turbines easily reach lower clouds at winter time even close to the sea coasts. How future large offshore plants will be affected by icing events is not clear at the moment, as the necessary information and meteorological measurements at various offshore sites are not yet available. Inland sites and especially sites in mountainous and northern regions as well as large turbines will be affected by ice during standstill and operation. The first large wind farms such as the Tauernwindfarm in Austria have been commissioned and first operation results are now available. Prototypes of wind turbines up to the Megawatt scale have been equipped with blade heating systems with special sensors and other features in order to fit the turbines to cold climate sites. However, no standard cold climate serial produced wind turbines are available on today's market. This paper summarises and discusses technical solutions and gives guidance on the systems which can be used for the various cold climate conditions.
