At present most wind farm controllers simply distribute power set point to the turbines evenly. The performance of the farm controller can be improved by utilizing the on-line measurements from each turbine in the farm. By reducing the power set point for the first rows of turbines in the up wind direction and thereby letting more wind through for the ...

Power Engineering Journal, 1993
As wind turbines become more common, electrical power engineers will be called on increasingly to design, build and operate wind farms. This article provides an introduction to the engineering of wind farms and discusses their particular implications for the distribution system.

In this study, applicability of offshore wind energy conversion systems in the Southern Marmara Region has been investigated. For this purpose, four different regions were selected and wind properties of the regions were assessed. Selected regions have been analysed by taking into account the wind data measured as mean daily time series.

A detailed gradiometry survey was conducted over approximately 6.7ha of mixed agricultural land located close to Hampole in Yorkshire. The data has identified several linear responses of probable archaeological origin, indicative of former field boundaries or in-filled ditches.

Transmission system operation with wind generators has been well analyzed for issues like forecasting, reliability, control, power quality, and fault ride through (FRT) impacts following large-scale integration. However, there are still no standardized protection schemes for wind farms such as those practiced for the protection of conventional ...

Renewable Energy Focus, 2011
INSTALLING A turbine onto its foundation and completing final assembly can be done in a day, but the full job of constructing a wind farm involves a long list of civil engineering and electrical work. It can take anything from one to three years, and calls for expert project management skills.

What does a poor agricultural county in the State of Washington, USA, known primarily for its wheat fields, cattle, and a scattered population, do when it sees wind projects going up in its neighbouring counties? It moves one step ahead, designs a “clean energy” economic development zone and invites the developers in!

IEE Half-day Colloquium on Lightning Protection of Wind Turbines, 1997
This paper examines the use of computer modelling to assess the suitability of windfarm grounding systems for protection against power system faults and lightning strikes. The transient behaviour of practical earthing system designs are presented using the general purpose EMTP program and the specialist CDEGS grounding analysis software.

Wind farm design - When other wind farms are close [PDF]
, 2009 This work presents an approach to evaluate the wind climate in a location close to another wind farm. It is shown that the effect of the upstream wind farm can be expressed in various impact parameters, and that these can be determined by using a dedicated planetary boundary layer solver.

In the future, wind energy will be playing a dominant role in raising the share of renewables in electricity generation. This will significantly reduce the emission of carbon dioxide and the use of fossil fuels. Land use limitations in areas with high population density are hindering the installation of new large wind farms. Offshore, however, there is
