Dynamic Simulation of Hydraulic Pitch Systems

{access view=!registered}Only logged in users can view the full text of the article.{/access}{access view=registered}Using its extensive knowledge of wind turbine operation, the Danish firm, AVN Energy, has developed a dynamic program which simulates the performance of hydraulic pitch systems during the emergency stopping of a wind turbine. The simulation program is based on a combination of verified accumulator and  hydraulic pitch cylinder models; both accumulators and cylinders are products of AVN Energy. The simulation program is designed to verify the performance of AVN Energy products in a hydraulic pitch system set-up. This means that before building a complete system the customers of AVN Energy are now in a position to test whether their hydraulic pitch system is correctly dimensioned and therefore able to perform the requested emergency stop of the wind turbine.
