Aerogenerator
Introduction
An aerogenerator is a small wind electric
generator having a capacity of up to 30 kW. Aerogenerators
are installed either in stand-alone mode or along with solar
photovoltaic (SPV) systems to form a wind-solar hybrid system
for decentralized power generation. An aerogenerator is suitable
for power generation in unelectrified areas having adequate
wind speeds. It consists of a rotor of 1-10 m diameter having
2-3 blades, permanent magnet generator, control devices, yaw
mechanism, tower, storage battery, etc. The aerogenerator
rotor starts moving at a wind speed of 9-12 km per hour. However,
it produces optimum power at the rated wind speed of 40-45
km per hour. The limitation of not being able to provide power
as and when it is required is overcome by storing it in a
battery bank.
Achievement
Aerogenerators and wind-solar hybrid systems require high
wind speeds and good solar radiation. Potential exists for
installation in Andhra pradesh, Gujarat, Karnataka, Kerala,
Madhya Pradesh, Maharashtra, Orissa, Rajasthan, Tamil Nadu,
Uttaranchal, Uttar Pradesh, West Bengal, and the windy regions
of Jammu and Kashmir and all north-eastern states.
- So far, about 1000 water-pumping windmills
- And 380 kW aggregate capacity of aerogenerators/wind-solar
hybrid systems have been installed in the country.
Cost
Aerogenerators cost about Rs 2.00-2.50 lakhs per kW. In addition,
the cost of installation including civil works is estimated
at Rs 5000 per kW. The repair and maintenance cost is about
Rs 2000 per kW per annum.
The West Bengal Renewable Energy Development Agency (WBREDA)
has installed six aerogenerators of 3-kW capacity each in
the existing SPV power plants at Sagar and Mousani islands.
A number of aerogenerators have been installed by the Maharashtra
Energy Development Agency (MEDA), and are working satisfactorily.
An aerogenerator of 3.2-kW capacity, installed at the Manashakti
Research Centre, Lonawala, is supplying electricity to illuminate
22 streetlights on the road connecting the centre's hostel
to the highway. The aerogenerator is visible from the Mumbai-Pune
highway.
