Case Study and Cost–Benefit Analysis on Implementation of CBM
The focus of this case study and cost–benefit analysis is an application of a condition-based monitoring (CBM) tool installed in a 700kW wind turbine generator at a project based in the USA. The installation was in response to reports that several wind farms had experienced catastrophic gearbox failures, resulting in exorbitant costs and lost revenues. It began in summer 2003 with a cooperative pilot study, the objective being implementation of a ‘trial installation’ that would demonstrate the benefits of a CBM system on a wind turbine to help prevent catastrophic failures.

A Commentary on the Issues Facing Wind Park Developers in the UK
The UK offshore wind energy sector is booming at the moment. This is largely because of the UK government’s ‘Renewables Obligation’ targets for the generation of electricity from renewable sources of 10% by 2010 and 15% by 2015. As the windiest country in Europe, the UK is in a very good position to fulfil the targets by installing many wind parks in the relatively shallow waters extending into the North Sea. In this article, the author describes the legal implications for offshore wind farms.

Optimising Capacitors for Wind Power Applications

All wind turbines face a similar set of challenges. They need to extract power at low wind speeds and fluctuating wind profiles in order to maintain adequate yield. They also need to ensure adequate power quality to operate appliances or to feed into a grid. In addition, the electrical system must be constructed to minimise losses and thereby maintain high efficiency and reliability. In this article, the author, from Vishay Intertechnology, Inc, discusses how capacitors can be optimised to meet these challenges.By Josef Reindl, Vishay ESTA, Theo van de Steeg and Frans van Roemburg, Vishay BCcomponents

Development of the Sheringham Shoal wind farm
Scira Offshore Energy (Scira) is developing a 315MW offshore wind farm 20km north of the Norfolk coast in UK waters. Scira is a special-purpose vehicle of Ecoventures from the Netherlands and SLP Energy from the UK. Ecofys BV is technical consultant to Scira, providing technical project management and specialist services. In this article the preparations for this large wind farm are described along the lines of the technical, organisational, economic and environmental requirements.By Quirin Sluijs, Manager Wind Energy, and Bernard van Hemert, Senior Consultant, Ecofys BV, The Netherlands

The Design of a Cost-Effective Turnkey Solution
Before an offshore wind farm site is installed, there must be a geographical survey, wind analysis and environmental impact study for the area in consideration. To conduct these surveys and studies it is beneficial to have a site monitoring. In this article the authors describe the design considerations for such a system.
