Dingfeng wind project was installed in Heilongjiang, China It was created in 2012 and is owned by Heilongjiang Zhongyu Investment.
It is near Raohe, Shuangyashan.
See below for data.
Generally speaking, economic wind power generators require a wind speed of 4.5 m/s (16 km/h) or larger.
The best location for a project like Dingfeng would have a near constant flow of non-turbulent wind all year round, having a minimum chance of abrupt effective bursts of wind. An important factor of turbine siting is moreover admission to local demand or transmission capaRaohe, Shuangyashan.
During the planning stages the Dingfeng wind farm would’ve been checked and validated through wind measurements. However, Dingfeng wind farm might have needed more than just meteorological data and measurements.
Collection of site-specific data for wind speed and direction could have been essential to determining site potential in order to finance the project. Winds around Raohe, Shuangyashan are evaluated for at least a year or so alongside the development of detailed maps. Only then are wind turbines installed.
Altitude would also possess a part to playin a project like Dingfeng. This is due to drag The surge in velocity with altitude is most remarkable at the surface and is affected by topography, surface roughness, and upwind hurdles such as trees or buildings. Velocity boosts with altitude and it is more evident near land and is transformed by landscape, surface and limitations.
Wind speeds escalating with altitude is part of a wind energy law. This anticipates wind speed rises with the 7th root of altitude. Doubling the height of a turbine, then, enhances the anticipated wind speeds by 10%, and the anticipated power by 34%.
The distance of 7x Rotor Diameter is placed between each turbine, ie they are spaced out so they don’t affect each other. But micrositing optimizes placement, specifically in hilly areas.
Individual turbines at Dingfeng 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 enhanced in voltage with 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 perhaps roads to each turbine site.
