A Numerical Study to Verify the Effects
The sensors for yaw control are usually located on top of the nacelle of horizontal axis wind turbines (HAWTs). However, because of the different relative positions of the rotor and the tower in upwind and downwind HAWTs, the position of the nacelle yaw sensors will also be reversed. Research has been carried out to quantify the effect that different factors have on the efficient running of the turbines in complex terrains and the results are presented in the following article.- Category: Articles
The PowerModule PM3000W
The rising demand and increasing penetration of wind-generated electricity has created a critical need for power conversion systems designed to meet the unique requirements of the wind power market. This article describes the benefits of American Superconductor's PowerModule PM3000W, a fully programmable, flexible and modular power converter developed specifically for wind power applications.- Category: Articles
The Wind Power of Tomorrow on Your Screen Today
Either for trading or for power system operation, wind power forecasts have become necessary input to the daily management of wind generation. While fast transfer of research results to operational and commercially available products has been witnessed over the last few years, there are still challenges to face in order for wind power forecasts to fully satisfy the needs of their various users.By Pierre Pinson, , Gregor Giebel and Henrik Madsen, Technical University of Denmark, Denmark .

ZephIR Minimises Risk for NaiKun's Offshore Wind Farm Development
ZephIR has now been used as the sole on-site resource assessment tool for the Hecate Strait wind farm project for 12 months. This article reflects on the pioneering approach taken by NaiKun Wind Development Inc and the results delivered by ZephIR to date.- Category: Articles
Endurance Calculations for Bearings
Practical experience has shown that seemingly identical rolling bearings operating under identical conditions will not necessarily exhibit the same endurance life. Standardised life calculation methods can help us make educated choices about a bearing size's suitability for a particular application.- Category: Articles
Regional Market Integration as an Opportunity for Wind Energy
The development of the European internal electricity market is essential for an efficient integration of wind energy into the power system. The deregulation process was firstly characterised mainly by the opening of national markets. Lately, the emergence of supranational, regional power markets adds a truly European dimension by enabling flexible power trade over borders. Requirements for a market design that leads to an economically efficient integration of wind power on a continental scale are currently being investigated within the European TradeWind project. International markets allow the aggregation of widely distributed wind farms into flexible portfolios of supply and demand. Consequently, a good design of international power markets is essential for an efficient integration of wind energy into the power system.- Category: Articles
An EC FP7 Programme Mapping the North, Irish And Baltic Seas
NORSEWInD is an exciting new four-year programme that started on 1 August 2008. The general scope of the project is to create a wind speed database and associated wind atlas suitable for offshore wind farm development for the North, Irish and Baltic Seas.Stay informed with Windtech International!

| Every week on our website and in our email newsletter we want to show you that wind energy is more than just technology. We therefore invite you to send stunning pictures of wind turbines inspired by “light” (in the broadest sense of the word). After 52 submissions we will announce the winner of the year’s best picture! Email your photo to Include turbine model, location and name of photographer. (size of the published photo will be 336 px width x 280 px high). |
