The IEC 61400 Wind turbine generator systems standards are the reference used for the certification of wind turbines. The IEC61400-2 focuses in design requirements for small wind turbines but they are not applicable to vertical-axis wind turbines (Wood, 2011). Technical standards should be considered in the design in order to ensure safe-

There are two main types of wind turbines. The two general categories for wind turbines include vertical axis or horizontal axis wind turbines. The turbines are classified upon how the shaft of the generator is mounted. The horizontal axis wind turbine HAWT was invented before the vertical axis wind turbine (VAWT), which led to its popularity and

Vertical Axis Wind Turbine (VAWT) A wind turbine cannot be a wind turbine unless it has few blades. Likewise, the horizontal axis turbines, vertical axis ones also have a set of blades. But instead of spinning horizontally, they spin vertically. So, the rotational axis of a VAWT is in the vertical direction, and that's why it got such a name.
