Abstract

This paper summarises the tuning process of the Aerodynamic Platform Stabiliser control loop and its performance with Floating Offshore Wind Turbine model. Simplified Low-Order Wind turbine numerical models have been used for the system identification and control tuning process. Denmark Technical University’s 10 MW wind turbine model mounted on the TripleSpar platform concept was used for this study. Time-domain simulations were carried out in a fully coupled non-linear aero-hydro-elastic simulation tool FAST, in which wind and wave disturbances were modelled. This testing yielded significant improvements in the overall Floating Offshore Wind Turbine performance and load reduction, validating the control technique presented in this work.

Highlights

The world’s first medium scale Floating Offshore Wind Turbine (FOWT) BlueH was a modest affair compared to the current HyWind project, the floating pilot wind farm located in Scotland
The fact is that the investment required for the building, installation and decommissioning of FOWTs increase the Levelised Cost Of Energy (LCOE) more than other current wind energy production solutions such as bottom fixed offshore wind turbines [1]
The wind profile was generated with TurbSim v1.06.00 for the Design Load Case (DLC) 1.1 as defined by the standard IEC61400-1 [17]

Summary

Introduction

The world’s first medium scale Floating Offshore Wind Turbine (FOWT) BlueH was a modest affair compared to the current HyWind project, the floating pilot wind farm located in Scotland The fact is that the investment required for the building, installation and decommissioning of FOWTs increase the Levelised Cost Of Energy (LCOE) more than other current wind energy production solutions such as bottom fixed offshore wind turbines [1]. Few countries in the world have shallow water areas as required for bottom fixed wind turbines, so most countries are forced to resort to floating solutions. There is a number of different FOWT designs at present, but there is significant research going on and once the industry has settled on one or two basic designs, mass production can reduce costs
