Startup wind speed refers to the wind speed that can generate usable electrical energy. In terms of grid connection, it can be understood as the wind speed that can be connected to the grid to generate electricity.
Starting the wind turbine can be a little annoying. Due to the influence of inertia and resistance, the wind turbine cannot start by itself when the wind speed reaches the speed that can drive it to produce electricity. Instead, it draws energy from the power grid to start the wind turbine depending on the situation, and then the wind speed can cause the wind turbine to produce electricity. So it's hard to say without knowing exactly what you mean by "starting wind speed." Because the starting wind speed also depends on the power of the wind turbine, but basically as long as it reaches wind level 2 and the wind speedexceeds 3 meters/second, it can start. Typically, the wind turbine reaches the grid at full load. -connected wind speed, that is, the optimal wind speed is generally 10. The range is about 13 M/S, which corresponds to level 6-7 wind speed. Usually, in strong winds, the IEC also states that the wind speed of the wind turbine can basically exceed the wind speed range of 12 or more (but I am not sure of this statement, and I do not don't really think so). Therefore, when we usually choose a location for wind power generation, we not only need to have wind all year round, but also need the wind speed to be as stable as possible. There are more details to be given, so I'll give you an overview first.
