Dashentang Extension wind project was set up in Tianjin, China It was finished in 2012 and is owned by Tianjin Jinneng Investment Company.
It is near Dashentang Village, Hangu District.
See below for data.
Wind farms, as a general rule require wind speeds of 4.5 metres per second or higher.
A great position for a project like Dashentang Extension might have a near constant flow of non-turbulent wind year round, having a minimum probability of abrupt powerful bursts of wind. An important factor of turbine siting is furthermore admittance to local requirement or transmission capaDashentang Village, Hangu District.
During the planning stages the Dashentang Extension wind farm would have been checked and endorsed through wind measurements. However, Dashentang Extension wind farm might have needed more than simply meteorological data and measurements.
Site info around Dashentang Village, Hangu District is a major aspect in the ‘development’ conclusion Local winds are frequently watched for a year or more, and comprehensive wind maps constructed before wind generators are set up.
The wind blows more rapidly at higher altitudes because of the reduced effect of drag. The increase in velocity with altitude is most remarkable close to the surface and is impacted by geography, surface roughness, and upwind limitations such as trees or buildings. Velocity rises with altitude and it is more evident near land and is changed by terrain, surface and hurdles.
Wind speeds raising with altitude is part of a wind energy law. This Tianjins wind speed rises with the 7th root of altitude. Doubling the elevation of a turbine, then, raises the expected wind speeds by 10%, and the expected power by 34%.
The distance of 7x Rotor Diameter is placed between each turbine, ie they’re spaced out so that they don’t affect one another. However this might not be the case in hilly areas.
Dashentang Extension turbines are linked via medium voltage lines and communications.
At a substation, this kind of medium-voltage electric energy is increased in voltage using a transformer for link with the high voltage transmission system. Development of a land-based wind farm requires installing of the collector system and substation, and probably roads to each turbine site.
