Field Testing of Flatness-Based Feedforward Control on the CART2

چکیده
Nacelle-based lidar systems are offering a good opportunity for new wind turbine control strategies, since inflowing wind information can be used in the controller. The benefits of lidar-assisted collective pitch feedforward control have been presented over the last years and was successfully demonstrated in several field testings, latest results see [1, 2]. This controller yields an improved rotor speed regulation and a reduction of structural loads above rated wind speed. While lidar-assisted control using only the generator torque is less promising [3, 4], multivariable controller such as Model Predictive Control [5] or flatness-based feedforward control [6] can yield further control performance below rated wind speed. This paper presents the results from a field testing of a flatness-based feedforward controller in 2015.

Field Testing of Feedforward Collective Pitch Control on the CART2 Using a Nacelle-Based Lidar Scanner
This work presents the first results from a field test to proof the concept of LIDAR assisted collective pitch control using a scanning LIDAR device installed on the nacelle of a research turbine. The purpose of the campaign was to show that a reduction of rotor speed variation is feasible with a feedforward update without changing the feedback controller. Although only a small amount of data c...

متن کاملComparison of the effects of two flatness based control methods for STATCOM on improving stability in power systems including DFIG based wind farms
Power grids are complex, interconnected and nonlinear systems, and this will be more severe when they are subjected to high wind resources penetration. Static synchronous compensators (STATCOM) are used to improve voltage regulation and to meet grid codes in power systems, including doubly fed induction generators (DFIG) based wind farms. Despite the nonlinear nature of STATCOM, the conventiona...

Optimal linear controllers and high computational non-linear controllers are normally applied to control the nonlinear systems. Flatness control method is a control technique for linear systems as well as nonlinear systems by static and dynamic feedback namely as endogenous dynamic feedback. This method takes into account the non-linear behavior of the process while preventing complicated compu...
