Title: Trends in Region 3 Control System Performance as Wind Turbine Size Increases
Authors: John O'Brien
Abstract: Wind turbines are complex, nonlinear systems subjected to large loads that reduce performance and lifetime. To ameliorate this, high performance control systems must be implemented. Plant characteristics such as flexible body dynamics and nonminimum phase reduce available control performance as their size increases. A comparative analysis of available control performance for a 600 kW and a 5 MW wind turbine is presented. Control limitations for each are identified, and available feedback is quantified. Dimensionless parameters are defined to provide response-based measures for comparison. Results of nonlinear simulations for both wind turbines are presented and compared. Aggressive control strategies are developed in an attempt to improve the performance of the larger wind turbine's controllers.
