Discrete-time Control Stategies for Horizontal Axis Wind Turbines
نویسندگان
چکیده
This paper introduces two discrete-time controllers for horizontal axis wind turbines (HAWTs): a Linear Quadratic Gaussian (LQG) one and a model predictive (MPC) one. The LQG controller aims to strongly attenuate the disturbances influence on the system output. The control objective consists of keeping the output power constant, despite the wind variation, and thus reducing the fatigue that involves damaging the turbine components. The MPC provides an integrated solution for controlling systems with interacting variables, complex dynamics and constraints. Both controllers have the advantage that can easily be implemented and in case of HAWTs.

Determination of significant sources generating low-frequency noise in horizontal axis wind turbines
Several studies show that the Low-Frequency Noise (LFN) of wind turbines could have harmful effects on human health even when it is infrasound. In traditional classifications, the LFN of upwind turbines is referred only to steady thickness and steady loading sources, and the effect of vortices is considered negligible. In this study, the LFN of a horizontal axis wind turbine is simulated in win...

Every year the number of installed wind power plants in the world increases. The horizontal axis wind turbine is the most common type of turbine but there exist other types. Here, three different wind turbines are considered; the horizontal axis wind turbine and two different concepts of vertical axis wind turbines; the Darrieus turbine and the H-rotor. This paper aims at making a comparative s...
متن کاملDesign of a Permanent-Magnet Synchronous Generator for a 2 MW Gearless Horizontal-Axis Wind Turbine According to its Capability Curves
Permanent-Magnet Synchronous Generators (PMSGs) exhibit high efficiency and power density, and have already been employed in gearless wind turbines. In the gearless wind turbines, due to the removal of the gearbox, the cogging torque is an important issue. Therefore, in this paper, at first, design of a Permanent-Magnet Synchronous Generator for a 2MW gearless horizontal-axis wind turbine, acco...
متن کاملAdaptive Disturbance Tracking Control for Large Horizontal Axis Wind Turbines with Disturbance Estimator in Region II Operation
A new control problem called Disturbance Tracking Control (DTC), which arises in active control of variable speed horizontal axis wind turbines for electric power generation, was developed previously. Feedback control of a linear plant, which is persistently disturbed, must cause the plant output to track a linear function of the disturbance. This control theory is related to Tip Speed Ratio Tr...
