covered Energy Resource in thispresentation … Western Rajasthan – Potential Energy Zone Rajasthan – Preferred State for Solar Energy Power Scenario Solar Power Potential in Rajasthan Growth of Wind and solar Energy Solar Power Projects- Current Status Key investors and developers Advantages – Rajasthan Hybrid and Integration of Solar Energy with NaturalGas
Rajasthan – Preferred State for SolarEnergy The state in its western part blessed with abundantnatural resource i.e. optimum sunshine and wind With more than 325 days of sunshine every year The state has the highest solar radiation in the country Jodhpur, popularly known as the SUN CITY of India Assured power evacuation arrangements in place.Setting up 400 / 220 / 132 KV network for solar andwind energy based power plants in progress.
Rajasthan – Preferred State for SolarEnergy• Rich in mineral resources, viz. marble, granite,rock phosphate, zinc, lignite, Lime stone steelgrade etc. Per Capita electricity availability – 561 units Vast potential for Power Generation fromWind, Solar , Biomass, Petroleum and NaturalGas in Western Rajasthan.
INTRODUCTIONWind From The Sun is a new technology forobtaining power from the sun and wind.This hybrid system turns the suns light intoheat, then uses that heat to create a windwithin a horizontal large-diameter pipe.The wind inside the pipe is converted intoelectric power using a series of wind turbines.Provides a greater degree of control andpredictability.
SOLAR COLLECTORMATERIAL converts the energy from sunlight into heat.Must have low reflectivity, dark color.Does not need to have high thermal mass.Increase in temperature drives the entiresystem.Made of black ceramic gravel.The higher the temperature of the collector,wind power the system can generate.
SIZE :-Optimum size depends on a number of factors .It is similar to solar chimney power plant.Solar chimney power plant-solar collector-.4000m (dia) & 1500m high-600GWH/yearA wind from sun power plant is best located inregions receiving 2300KWH/m2/year.Energy of the system is given by multiplyingarea by amount of solar radiation.Sufficient increasing area results in increasedpower output
TEMPERATUREMust be hotter than the surrounding land.For sea-breeze difference is 100C – wind speedis 12m/s.Hotter towards the centre & cooler towards theperimeter. Large collector has fewerperimeters/unit area.
AIR MOVEMENT• HOT AIR RISES:No. of factors makes the rising columnnarrower. The collector is hotter in its centre making theair hotter & rises faster.The hotter air towards the centre rises fasterthan that over the perimeter.The rising air at the centre meets with leastresistance.
AIR CHANNELSAir moves from high pressure to low pressure,creating a wind within the pipe.The amount of wind power generated by thissystem depends on the air pressure differencefrom the center of the collector to thesurrounding land.The sun is higher in the sky and gives moresunlight in the summer than in the winter.
The hot air rising from the center of the collectorcreates and maintains a low pressure area in thecenter of the collector.The pipes have a constant difference in airpressure from one end to the other. This differencein air pressure moves air through the pipes.Each pipe has pressure-staged wind turbineswhich present a kind of obstacle to the airmovement.The wind turbines remove mechanical energyfrom the wind in the pipes and convert it toelectricity.
WIND TURBINES A series of very large wind turbines withinthe pipe turn the wind into electricity with ahigh degree of efficiency.Operates over a wide range. When the speedincreases the turbine’s rotational speed increases.Hence results in greater available.Swept area is roughly proportional to power outputthe output would be increased by 40% by using onelarge wind turbine, instead of 7 smaller ones
CONCLUSIONThis type of system produce powerAir must move from high to low pressurethrough the air channel & wind turbines.Has not been built & tested to determine howmuch power will be produced.Alternate Design: to increase efficiency, placeair channel so that one end is over a large bodyof water. The water will be much cooler thanthe collector and will increase the air pressuredifference along the air channel.
