Testing of the FolksWind 1.5kW vertical axis wind turbine

, 2011
In recent years the small wind industry has shown exponential growth; however there have been growing concerns over the safety and reliability of small wind turbines on the market. The International Electrotechnical Committee and the International Energy

Learning curves and changing product attributes: the case of wind turbines

, 2006
The heuristic concept of learning curves describes cost reductions as a function of cumulative production. A study of the Liberty shipbuilders suggested that product quality and production scale are other relevant factors that affect costs.

A successful roof-top wind power project?

, 2010
Roof-top wind power projects have a well documented record of very poor performance. The primary objective of this project has been to provide advice in the planning phase of a roof-top wind project to ensure its success.

Condition monitoring benefit for offshore wind turbines

, 2012
As more offshore wind parks are commissioned, the focus will inevitably shift from a planning, construction and warranty focus to an operation, maintenance and investment payback focus.

An experimental investigation of wind turbine wakes using Particle Image Velocimetry

, 1993
Determination of the aerodynamic performance of horizontal-axis wind turbines (HAWT) is complicated by problems such as wake deformation effects and free stream turbulence.

Multi-disciplinary robust design of variable speed wind turbines

, 2011
This paper addresses the preliminary robust multi-disciplinary design of small wind turbines. The turbine to be designed is assumed to be connected to the grid by means of power electronic converters.

Improved cost energy comparison of permanent magnet generators for large offshore wind turbines

, 2014
This paper investigates geared and direct-drive permanent magnet generators for a typical offshore wind turbine, providing a detailed comparison of various wind turbine drivetrain configurations in order to minimise the Cost of Energy.

Integration of wind energy systems into the grid: power quality and technical requirements

, 2010
The integration of wind energy into the utility network has increased significantly over the past years largely as a result of the increasing environmental concerns arising from the use of fossil fuels, coupled with the anticipated global increase in oil.

US military, airspace, and meteorological radar system impacts from utility class wind turbines: Implications for renewable energy targets and the wind industry

, 2013
A substantial number of wind energy projects have been stalled or abandoned in the United States of America (US) due to concerns over the effects of wind turbines on radar installations.

Simulating wind turbine interactions using the vorticity transport equations

, 2009
The aerodynamic interactions that can occur within a wind farm result in the constituent turbines generating a lower power output than would be possible if each of the turbines were operated in isolation.
