Collgar wind farm is located in Western Australia, Australia. It was finished in 2011 and is owned by Retail Employees Superannuation Trust (REST), UBS International Infrastructure Fund.
It is near 25 km SE Merredin.
See below for data.
Wind farms, as a general rule require wind speeds of 4.5 metres per second or higher.
The very best destination for something like Collgar would be a steady availability of non-turbulent wind. An important factor of turbine siting is also access to local requirement or transmission capa25 km SE Merredin.
During the planning stages the Collgar wind farm would have been checked and validated through wind measurements. However, Collgar wind farm would have needed more than simply meteorological data and measurements.
Site data around 25 km SE Merredin is a major element in the ‘development’ decision Local winds are frequently watched for a year or more, and detailed wind maps made before wind generators are set up.
The wind hits quicker at greater altitudes due to the reduced effect of drag. The surge in velocity with altitude is most dramatic at the surface and is affected by topography, surface roughness, and upwind obstructions such as trees or buildings. Velocity rises with altitude and is more distinct near land and is altered by landscape, surface and obstacles.
Generally, the growth of wind speeds with increasing height follows a wind profile power law, which predicts that wind speed rises proportionately to the seventh root of altitude. Increasing the altitude of a turbine, then, boosts the predicted wind speeds by 10%, and the expected power by 34%.
The distance of 7x Rotor Diameter is placed between each turbine, ie they are spaced out in order that they don’t affect one another. But micrositing maximizes placement, particularly in hilly areas.
Individual turbines at Collgar are interlocked with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, it medium-voltage electric energy is improved in voltage using a transformer for connection to the high voltage transmission system. Construction of a land-based wind farm requires setting up the collector system and substation, and possibly roads to every turbine site.
