Wind Energy FAQs



Q. How is Wind Data collected?

A. To collect wind data, a meteorological tower is installed with anemometers to determine the wind speed and wind vanes to determine the direction.

The heights of these  towers generally vary from 30 to 60 meters. The towers are primarily steel-pipe structures, which are left to collect data for one to two years and then disassembled.

Data is collected by a data logging device, which stores and transmits data for analysis. Great attention must be paid to the exact positions of the turbines (a process known as micro-siting) because differences of as little as 30 meters can nearly double the energy production. 

 


Q. How are sites selected for installing Wind Turbine Generators?

A. The sites are selected for installing and commissioning wind turbines based on the following criteria:  

1)      A near constant flow of non-turbulent wind throughout the year  

2)      Minimum likelyhood of sudden powerful bursts of wind  

3)      Access to local demand or transmission capacity  

Sites are selected based on a wind atlas, and validated with wind measurements. 
The operational wind speed for wind turbines is generally between 4.5 m/s and 25 m/s, depending on their design. Local winds are often monitored for a year or more, and detailed wind maps constructed before wind turbines are installed.


Q. Wind does not always blow, so how will a wind turbine generate energy all the time?

A.   True, wind does not blow always. Hence extra effort is put in identifying optimal sites for installing Wind Turbines. Wind energy is reliable and efficient. Wind turbines are available to generate electricity 99% of the time, on par with other generating sources. Unlike other power plants, wind energy systems require minimal maintenance and have low operating expenses.   

WinWinD has gone a step further and developed machines that are known for their efficiency at low wind speeds.


Q.Wind energy is expensive, isn’t it?

A. The initial start-up costs of wind turbines are relatively much less than those involved in setting up conventional power plants. The running costs of wind power plants are  minimal in comparison to most other forms of energy generation. Research has proven that when it comes to the purchase cost versus the cost per rated watts, wind power is more cost effective than other means of energy generation.


Q. Aren’t wind turbines noisy?

A.  Wind turbines make some noise, but this noise level is comparable to the background noise of everyday life, or the sound of the wind blowing. WWD turbines, however, can be controlled to limit the amount of noise they produce.


Q. Wind power isn't so easy to integrate into local grids, I hear them say?

A. This is true for many turbines, but WinWinD (WWD) wind turbines have been designed to meet the strictest grid requirements.
