Daan Lesheng II wind project was installed in Jilin, China It was brought online in 2015 and is owned by AVIC Heavy Machinery co,.Ltd.
It is near Lesheng County, Daan.
See below for data.
Wind farms, as a general rule demand wind speeds of 4.5 metres per second or higher.
An ideal position for a project like Daan Lesheng II might have a near constant flow of non-turbulent wind throughout the year, having a minimum chances of abrupt potent bursts of wind. An important factor of turbine siting is furthermore access to local requirement or transmission capaLesheng County, Daan.
Before building, Daan Lesheng II was probably screened on the basis of a wind atlas, and validated with 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 might have been vital to determining site potential to be able to fund the project. Winds around Lesheng County, Daan are analysed for at least a year or so plus the creation of detailed maps. Only then are wind turbines installed.
Altitude would also have a part to performin a project like Daan Lesheng II. This is because of drag The increase in velocity with altitude is most dramatic at the surface and is affected by geography, surface roughness, and upwind limitations such as trees or buildings. Velocity boosts with altitude and it is more distinct near land and is transformed by geography, surface and obstacles.
Wind speeds raising with altitude is part of a wind energy law. This predicts wind speed rises with the 7th root of altitude. Increasing the altitude of a turbine, then, increases the expected wind speeds by 10%, and the predicted power by 34%.
The distance of 7x Rotor Diameter is placed between each turbine, ie they’re spaced out to make sure they don’t affect each other. But micrositing increases placement, particularly in hilly areas.
Individual turbines at Daan Lesheng II are connected with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, it medium-voltage electric current is elevated in voltage using a transformer for link with the high voltage transmission system. Building of a land-based wind farm requires installing of the collector system and substation, and probably roads to each turbine site.
