Differences between Requirements of IEC.
Design Documentation Requirements per IEC. You may have heard that IEC defines wind turbine classes with labels like IIIB, where the roman number refers to a reference wind speed and the index letter refers to a turbulence category. To verify that a wind turbine belongs to a give wind turbine class, it must be proven safe under a set of predefined load cases. The standard was intended to succeed national regulations in the EU and elsewhere.
The new edition gives more flexibility to the designer to optimize his turbine in accordance with real site conditions. Compared to the previous edition, especially the extreme load determination has been . The wind speed parameters for each class are given in Table . The UK participation in its preparation was entrusted to Technical Committee.
