Why safe automation for wind turbines?

Accidents on wind turbines have unpleasant consequences. In the simplest case it can lead to loss of production, which may involve compensation payments to the operator. In a worse case it can lead to a total loss of investment, due to fire for example. And any accident on a wind turbine generates negative media interest.

The hazards emanating from a wind turbine are many and varied. Most cases involve overload, such as overspeed due to heavy winds or exceeding the maximum pitch tolerance, missing position indicators for the rotor blade positions and similar. Protecting maintenance and service personnel, monitoring E-STOP pushbuttons, safe positioning of the rotor and gondola, monitoring shearpin breakage and speed - these are just some of the safety technology requirements on wind turbines.
