Characterization of wind turbine flow through nacelle-mounted lidars: a review

Abstract

This article provides a comprehensive review of the most recent advances in the planning, execution, and analysis of inflow and wake measurements from nacelle-mounted wind Doppler lidars. Lidars installed on top of wind turbines provide a holistic view of the inflow and wake characteristics required to characterize and optimize wind turbine performance, carry out model validation and calibration, and aid in real-time control. The need to balance the enhanced capabilities and limitations of lidars compared to traditional anemometers inspired a broad variety of approaches for scan design and wind reconstruction, which we discuss in this review. We give particular emphasis to identifying common guidelines and gaps in the available literature with the aim of providing an exhaustive picture of the state-of-the-art techniques for reconstructing wind plant flow using nacelle-mounted lidars.

Functional integration design and aerodynamic characterization of a hexacopter agricultural unmanned aerial vehicle based on its appearance

“…The research mainly uses CFD to numerically simulate the aerodynamic sensors, gyroscopes, wind speed sensors, and pressure sensors, and analyze the aerodynamic characteristics of multi rotor unmanned aerial vehicles. Since the AC of the multi-rotor vehicle has high requirements on the distribution of pressure and velocity fields, the iterative method selected for the study is the SIMPLE algorithm, which is mainly used to solve the numerical simulation of incompressible flow (Letizia et al, 2023).…”

“…They offer remote sensing and are able to provide a great characterization of the future incoming flow, enabling feedforward approaches (Letizia et al, 2023;Scholbrock et al, 2016). Though industrial use of LiDARs for control applications has been reported (Raach, 2021), their cost, complexity of installation, or need for synchronization with the SCADA system still limit their broad use.…”
