It is near Dalian.
See below for data.
In most cases, economic wind generators require a wind speed of 4.5 m/s (16 km/h) or larger.
The best destination for something such as Dalian I is a steady supply of non-turbulent wind. An important factor of turbine siting is also access to local requirement or transmission capaDalian.
During the planning stages the Dalian I wind farm would have been checked and confirmed through wind measurements. However, Dalian I wind farm might have needed more than simply meteorological data and measurements.
Collection of site-specific data for wind speed and direction might have been important to determining site potential to be able to finance the project. Local winds are often watched for a year or more, and detailed wind maps constructed before wind generators are installed.
The wind hits faster at greater altitudes as a result of reduced influence of drag. The rise in velocity with altitude is most remarkable near the surface and is impacted by landscape, surface roughness, and upwind limitations such as trees or buildings. Velocity grows with altitude and is also more distinct near land and is transformed by terrain, surface and obstacles.
Almost always, the growth of wind speeds with growing elevation follows a wind profile power law, which forecasts that wind speed rises proportionately to the seventh root of altitude. Increasing the elevation of a turbine, then, increases the anticipated wind speeds by 10%, and the predicted power by 34%.
In general, a range of 7D (7 × Rotor Diameter of the Wind Turbine) is about between each turbine in a fully developed wind farm. However this is not always the case in hilly areas.
Individual turbines at Dalian I 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 energy is enhanced in voltage using a transformer for link with the high voltage transmission system. Construction of a land-based wind farm requires setting up the collector system and substation, and probably roads to each and every turbine site.
