Abstract
Work Package 3 of the TotalControl project is concerned with developing and testing adaptations of the wind turbine controller which could be beneficial in the context of wind farm control. In Task 3.1, various controller adaptations were developed, and tested in simulations, while in Task 3.2, controller adaptations were implemented and tested on a real turbine in the field, namely the 7MW Levenmouth Demonstration Turbine (LDT) just off the coast of Eastern Scotland. This document is a report on those field tests, covering the implementation of all the different tests and the data collected, together with some preliminary analyses of the experimental results.
The following experiments were performed:
• Yaw misalignment tests, useful for wake steering control for wind farms
• Delta control tests, useful for axial induction control for wind farms, power curtailment and some grid ancillary services
• Derating tests, for power curtailment and load minimisation
• LiDAR-assisted control tests, using wind preview information from a forward-facing LiDAR to improve the control action and reduce loads
• Enhancements to the individual pitch control, to further reduce loads and allow the use of cheaper sensors
• Fast frequency response tests, intended to help enhance grid stability in the presence of a high penetration of renewables
The experiments have yielded a large amount of valuable data, including concurrent inflow and wake flow data from two scanning LiDARs which were installed for the project, as well as met mast data and turbine performance and loading data. The data will continue to be analysed well beyond the end of the TotalControl project, and further results will be published in due course.
