Cerro Chato II (formerly Coxilha Negra VI) wind project was installed in Rio Grande do Sul, Brazil It was completed in 2011 and is owned by Eletrosul.
It is near Sant’Ana do Livramento.
See below for data.
Wind farms, as a general rule call for wind speeds of 4.5 metres per second or more.
The best position for a project like Cerro Chato II (formerly Coxilha Negra VI) could have a near constant flow of non-turbulent wind year round, having a minimum probability of sudden powerful bursts of wind. An important factor of turbine siting is moreover access to local requirement or transmission capaSant’Ana do Livramento.
During the planning stages the Cerro Chato II (formerly Coxilha Negra VI) wind farm would have been checked and validated through wind measurements. Meteorological wind data alone is usually not sufficient for correct siting of a large wind power project.
Site info around Sant’Ana do Livramento would have been a major aspect in the ‘development’ final decision Winds around Sant’Ana do Livramento are examined for over a year or so plus the creation of detailed maps. Only then are wind turbines installed.
Altitude would also possess a part to performwithin a project like Cerro Chato II (formerly Coxilha Negra VI). This is because of drag The rise in velocity with altitude is most extraordinary at the surface and is impacted by topography, surface roughness, and upwind limitations such as trees or buildings. Velocity rises with altitude and is also more distinct near land and is transformed by terrain, surface and obstacles.
Wind speeds escalating with altitude is part of a wind energy law. This Rio Grande do Suls wind speed rises with the 7th root of altitude. Doubling the altitude of a turbine, then, increases the predicted wind speeds by 10%, and the estimated power by 34%.
The distance of 7x Rotor Diameter is placed between each turbine, ie they’re spaced out in order that they don’t affect each other. However this may not be the situation in hilly areas.
Individual turbines at Cerro Chato II (formerly Coxilha Negra VI) are connected with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, that medium-voltage electric energy is elevated in voltage with a transformer for connection to the high voltage transmission system. Building of a land-based wind farm requires installing of the collector system and substation, and perhaps access roads to each turbine site.
