Question

Answer question numbers 3(a) (c) on the basis of your understanding of the following
peragraph and the related studied concepts.
Renewable energy sources such as wind energy are vital for the Indian economy, not only from
the point of view of supply, but also from the perspective of environmental and social benefits
India is the world's fifth largest wind power producer and the largest windmill facilities in India
are installed in Tamil Nadu. Muppandal is a small village of Tamil Nadu and one of the most
important sites of wind farm in the state. It uses wind from the Arabian Sea to produce
renewable energy. The suitability of Muppandal as a site for wind farms stems from its
geographical location as it has access to seasonal monsoon winds. the electrical generators
used on wind turbines in sites like Muppandal, produce an output AC of 240V and a frequency at
50Hz even when the wind speed is fluctuating. A transformer may be required to increase or
decrease the voltage so it is compatible with the end usage, distribution or transmission voltage
depending on the type of interconnection.
3(a)State the principle behind electric generator.
3(b)The output frequency of wind turbine is 50Hz.what is meant by this statement?
3(C )Why do you think Muppandal is at an advantageous position for this

Answer:

3(a) (c) on the basis of your understanding of the following

peragraph and the related studied concepts.

Renewable energy sources such as wind energy are vital for the Indian economy, not only from

the point of view of supply, but also from the perspective of environmental and social benefits

India is the world's fifth largest wind power producer and the largest windmill facilities in India

are installed in Tamil Nadu. Muppandal is a small village of Tamil Nadu and one of the most

important sites of wind farm in the state. It uses wind from the Arabian Sea to produce

renewable energy. The suitability of Muppandal as a site for wind farms stems from its

geographical location as it has access to seasonal monsoon winds. the electrical generators

used on wind turbines in sites like Muppandal, produce an output AC of 240V and a frequency at

50Hz even when the wind speed is fluctuating. A transformer may be required to increase or

decrease the voltage so it is compatible with the end usage, distribution or transmission voltage

depending on the type of interconnection.

3(a)State the principle behind electric generator.

3(b)The output frequency of wind turbine is 50Hz.what is meant by this statement?
