New Development Secures Achievement of Requested Emergency Pitch Stroke

avnAVN Energy has developed a dynamic simulation model that can be used to verify the performance of its hydraulic pitch systems. The basic idea of the program is to facilitate pitch simulation with user-specific parameters in order to simulate the physical and environmental conditions of a wind turbine. Using this newly developed simulation program users can investigate if the accumulators, cylinders and valves have the correct dimensions in proportion to each other and thus can always achieve the requested emergency pitch stroke.
