Big Spring II wind project was set up in Texas, USA It was completed in 1999 and is owned by Caithness Energy.
It is near Howard County.
See below for data.
Wind farms, as a general rule need wind speeds of 4.5 metres per second or higher.
A perfect destination for a project like Big Spring II could have a near constant flow of non-turbulent wind all year round, having a minimum chances of abrupt potent bursts of wind. Additionally, you wouldn’t get a turbine Caithness Energy like Caithness Energy associated if Big Spring II was not built near local demand or transmission capaHoward County.
During the planning stages the Big Spring II wind farm would have been checked and authenticated through wind measurements. However, Big Spring II wind farm would have needed more than simply meteorological data and measurements.
Site information around Howard County would have been a major aspect in the development final decision Local winds are frequently watched for a year or more, and comprehensive wind maps built before wind generators are installed.
The wind hits quicker at higher altitudes due to the reduced effect of drag. The increase in velocity with altitude is most dramatic at the surface and is affected by landscape, surface roughness, and upwind obstacles such as trees or buildings. Velocity grows with altitude and is also more evident near land and is transformed by topography, surface and obstructions.
Wind speeds raising with altitude is part of a wind energy law. This Texass wind speed rises with the 7th root of altitude. Increasing the height of a turbine, then, boosts the anticipated wind speeds by 10%, and the estimated power by 34%.
In general, a length of 7D (7 × Rotor Diameter of the Wind Turbine) is scheduled between each turbine in a fully developed wind farm. However this might not be the situation in hilly areas.
Individual turbines at Big Spring II are interlocked with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, this kind of medium-voltage electric current is increased 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 probably access roads to each turbine site.
