Title: Analysis and simulation of a wind turbine with variable speed

Technical Report ·
OSTI ID:6524951

An appropriate controller must be designed if the desired performance of a wind turbine with a synchronous generator and AC/DC/AC conversion is to be achieved. The dynamic performance of such a system was therefore investigated. The wind turbine was simulated at several operating points, using a detailed nonlinear model. It is shown that the sensitivity of the wind turbine to changes of the pitch angle depends largely on the operating conditions and thus enhances the need for robust or adaptive control. The interaction between the mechanical and electrical parts was also investigated. The characteristic dynamics are quantified with an eigenvalue analysis which also shows that the system has both very fast and very slow dynamics. The results obtained indicate the need for more-systematic control design procedures dealing with all relevant dynamics.
