From above explanation, the survival wind speed of Class III wind turbine is:
=1.4 -1.4 *7%=1.4*37.5-1.4*37.5*7%=52.5-3.68=48.82m/s (
＜
50m/s)
So this is why the survival wind speed of Tumo-Int wind turbine is 50m/s.
Generally speaking, the safety and operation of wind turbine is closely related with matching components, correct pole installation, correct system cable
connection, these three factors we could control and we have to do them well, However, wind turbines are installed outdoors, it is also close with natural
environment situations, in case of force majeure factors, such as storm, earthquake, or attacked by hailstone, dust, wind turbines may be damaged
