It is near Ge‘ermu, Haixi.
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 Dagele could have a near constant flow of non-turbulent wind year round, with a minimum chance of abrupt potent bursts of wind. An important factor of turbine siting is moreover admittance to local demand or transmission capaGe‘ermu, Haixi.
Before construction, Dagele was most likely screened on the basis of a wind atlas, and validated with wind specifications. However, Dagele wind farm would have needed more than just meteorological data and measurements.
Site information around Ge‘ermu, Haixi is a major factor in the ‘development’ final decision Local winds are often monitored for a year or more, and detailed wind maps created before wind generators are installed.
The wind blows speedier at higher altitudes because of the reduced effect of drag. The boost in velocity with altitude is most dramatic near the surface and is impacted by topography, surface roughness, and upwind obstructions such as trees or buildings. Velocity boosts with altitude and it is more pronounced near land and is changed by terrain, surface and hurdles.
Wind speeds escalating with altitude is part of a wind energy law. This forecasts wind speed rises with the 7th root of altitude. Doubling the altitude of a turbine, then, enhances the predicted wind speeds by 10%, and the expected power by 34%.
In general, a length of 7D (7 × Rotor Diameter of the Wind Turbine) is defined between each turbine in a fully developed wind farm. But micrositing increases placement, specially in hilly areas.
Individual turbines at Dagele are interconnected 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 enhanced in voltage using a transformer for connection to the high voltage transmission system. Development of a land-based wind farm requires installation of the collector system and substation, and probably roads to each and every turbine site.
