It is near Ninghai County.
See below for data.
For the most part, economic wind generators require a wind speed of 4.5 m/s (16 km/h) or bigger.
The very best destination for something like Chashan would be a steady availability of non-turbulent wind. An essential aspect of turbine siting is also admittance to local requirement or transmission capaNinghai County.
During the planning stages the Chashan wind farm would have been checked and validated through wind measurements. However, Chashan wind farm would have needed more than simply meteorological data and measurements.
Site info around Ninghai County would have been a major aspect in the ‘development’ final decision Local winds are frequently examined for a year or more, and comprehensive wind maps made before wind generators are set up.
Altitude would also have a part to playin a project like Chashan. This is due to drag The surge in velocity with altitude is most spectacular at the surface and is impacted by topography, surface roughness, and upwind obstacles such as trees or buildings. Velocity rises with altitude and it is more evident near land and is altered by terrain, surface and limitations.
Wind speeds increasing with altitude is part of a wind energy law. This Zhejiangs wind speed rises with the 7th root of altitude. Doubling the height of a turbine, then, enhances 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 they really don’t affect each other. But this is not always the case in hilly areas.
Individual turbines at Chashan are interlocked with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, this medium-voltage electric current is elevated 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 possibly access roads to each turbine site.
