Pitch Systems in Wind Turbines – Reducing Load and Enhancing Turbine Safety

All wind turbines are equipped with a certain power control feature in case the speed of the wind is too high or too low and to have a frequency coherent with the grid. The traditional and the simplest and least expensive method in this respect is a system of natural limitation known as “stall”. The blades are mounted directly on the hub at a fixed angle. When the wind (more…)
