It is near Heyuan City.
See below for data.
As a general rule, economic wind turbines require a wind speed of 4.5 m/s (16 km/h) or larger.
The best destination for something like Dongyuan Chanziding is a steady availability of non-turbulent wind. An essential aspect of turbine siting is also access to local requirement or transmission capaHeyuan City.
Before building, Dongyuan Chanziding was almost certainly screened on the foundation of a wind atlas, and validated with wind specifications. However, Dongyuan Chanziding wind farm might have needed more than just meteorological data and measurements.
Site information around Heyuan City would have been a major element in the development choice Winds around Heyuan City are analysed for over a year or so plus the introduction of detailed maps. Only then are wind turbines installed.
The wind blows more rapidly at higher altitudes as a result of reduced effect of drag. The rise in velocity with altitude is most dramatic near the surface and is impacted by topography, surface roughness, and upwind hurdles such as trees or buildings. Velocity increases with altitude and it is more distinct near land and is transformed by landscape, surface and limitations.
Usually, the growth of wind speeds with raising height follows a wind profile power law, which predicts that wind speed rises proportionately to the seventh root of altitude. Doubling the altitude of a turbine, then, increases the expected wind speeds by 10%, and the estimated power by 34%.
The distance of 7x Rotor Diameter is placed between each turbine, ie they’re spaced out so they don’t affect each other. However this isn’t necessarily the situation in hilly areas.
Individual turbines at Dongyuan Chanziding are interconnected with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, that medium-voltage electric current is increased in voltage with a transformer for connection to the high voltage transmission system. Development of a land-based wind farm requires setting up the collector system and substation, and probably access roads to every turbine site.
