Why on earth do all wind turbines have exactly three blades? ship propellers can manage with two – and one would immediately think that 4 or 5 blades would catch even more wind and therefore provide even more power. The 3-blade horizontal axis wind turbine is the most advantageous option, in several technical and operational…
Let’s take closer look at a typical sensor for a large wind turbine. The sensor mounts to the main frame; its gear is driven by the yaw ring. This sensor employs an incremental encoder that tracks nacelle position, along with a group of limit switches dedicated to cable twist control Here we can see the…
