Duerbote I (Ruihao) wind project was set up in Heilongjiang, China It was in fact brought online in 2008 and is owned by Heilongjiang Ruihao Technology Group.
It is near Daqing.
See below for data.
Generally speaking, economic wind machines require a wind speed of 4.5 m/s (16 km/h) or larger.
A perfect place for a project like Duerbote I (Ruihao) would have a near constant flow of non-turbulent wind all year round, with a minimum probability of sudden powerful bursts of wind. An essential aspect of turbine siting is moreover admittance to local requirement or transmission capaDaqing.
During the planning stages the Duerbote I (Ruihao) wind farm would have been checked and validated through wind measurements. Meteorological wind data alone is usually not enough for accurate siting of a large wind power project.
Assortment of site-specific data for wind speed and direction could have been vital to determining site potential as a way to fund the project. Winds around Daqing are evaluated for over a year or so plus the introduction of detailed maps. Only then are wind turbines installed.
The wind hits faster at higher altitudes due to the reduced influence of drag. The boost in velocity with altitude is most dramatic close to the surface and is affected by geography, surface roughness, and upwind obstructions such as trees or buildings. Velocity rises with altitude and it is more obvious near land and is changed by geography, surface and obstructions.
Wind speeds escalating with altitude is part of a wind energy law. This Heilongjiangs wind speed rises with the 7th root of altitude. Increasing the altitude of a turbine, then, boosts the predicted wind speeds by 10%, and the anticipated power by 34%.
In general, a distance of 7D (7 × Rotor Diameter of the Wind Turbine) is defined between each turbine in a fully developed wind farm. But this is not always the situation in hilly areas.
Duerbote I (Ruihao) turbines are linked via medium voltage lines and communications.
At a substation, this kind of medium-voltage electric energy is elevated in voltage with 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 access roads to each and every turbine site.
