A Method for Yaw Error Alignment of Wind Turbine Based on LiDAR

open access: yesIEEE Access, 2020
Yaw control is an important part of the control system of a horizontal shaft wind turbine. After the installation of the wind turbine, the turbulence influence of the wind turbine blades and the azimuth of the wind turbine will cause yaw error which ...

Wind Turbine Control Using PI Pitch Angle Controller [PDF]

open access: yesIFAC Proceedings Volumes, 2012
This paper suggests two methods to calculate the gains of a proportional-Integral pitch angle controller for a 5 MW wind turbine. The first method is analytical and the second one is based on simulation. Firstly, the power coefficient characteristics for different pitch angles are calculated. Secondly, the output powers vs.

Wind turbine condition monitoring strategy through multiway PCA and multivariate inference [PDF]

open access: yes, 2018
This article states a condition monitoring strategy for wind turbines using a statistical data-driven modeling approach by means of supervisory control and data acquisition (SCADA) data. Initially, a baseline data-based model is obtained from the healthy

Implementation of wind turbine controllers [PDF]

open access: yesInternational Journal of Control, 1997
Three of the important generic implementation issues encountered when developing controllers for pitch-regulated constant-speed wind turbines are considered; namely, accommodation of the strongly nonlinear rotor aerodynamics, automatic controller start-up-shut-down and accommodation of velocity and acceleration constraints within the actuator.

Comparison of wind farm control strategies under realistic offshore wind conditions: turbine quantities of interest [PDF]

open access: yesWind Energy Science
Wind farm flow control is a strategy to increase the efficiency and therefore lower the levelized cost of energy of a wind farm. This is done using turbine settings such as the yaw angle, blade pitch angles, or generator torque to manipulate the flow ...

Performance and Effect of Load Mitigation of a Trailing-Edge Flap in a Large-Scale Offshore Wind Turbine

open access: yesJournal of Marine Science and Engineering, 2020
As a result of the large-scale trend of offshore wind turbines, wind shear and turbulent wind conditions cause significant fluctuations of the wind turbine’s torque and thrust, which significantly affect the service life of the wind turbine gearbox

Iterative feedback tuning of wind turbine controllers [PDF]

open access: yesWind Energy Science, 2017
Traditionally, wind turbine controllers are designed using first principles or linearized or identified models. The aim of this paper is to show that with an automated, online, and model-free tuning strategy, wind turbine control performance can be ...
