Key investors and developers Advantages – Rajasthan Hybrid and Integration of Solar Energy with Natural Gas

Rajasthan – Preferred State for Solar Energy

The state in its western part blessed with abundant natural 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 and wind energy based power plants in progress.

Rajasthan – Preferred State for Solar Energy

• Rich in mineral resources, viz. marble, granite, rock phosphate, zinc, lignite, Lime stone steel grade etc.

Per Capita electricity availability – 561 units Vast potential for Power Generation from

Wind, Solar , Biomass, Petroleum and Natural Gas in Western Rajasthan.

Wind Energy based Power Plant

WIND FROM SUN POWER PLANT

INTRODUCTION

Wind From The Sun is a new technology for obtaining power from the sun and wind.

This hybrid system turns the sun's light into heat, then uses that heat to create a wind within a horizontal large-diameter pipe.

The wind inside the pipe is converted into electric power using a series of wind turbines.

Provides a greater degree of control and predictability.

SOLAR COLLECTOR

MATERIAL 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 entire

system. 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/year A wind from sun power plant is best located in regions receiving 2300KWH/m2/year.Energy of the system is given by multiplying area by amount of solar radiation. Sufficient increasing area results in increased power output

TEMPERATURE

Must be hotter than the surrounding land.For sea-breeze difference is 100C – wind speed is 12m/s.Hotter towards the centre & cooler towards the perimeter. Large collector has fewer perimeters/unit area.

AIR MOVEMENT

• HOT AIR RISES:No. of factors makes the rising column

narrower. The collector is hotter in its centre making the

air hotter & rises faster.The hotter air towards the centre rises faster

than that over the perimeter.The rising air at the centre meets with least

resistance.

AIR CHANNELS

Air moves from high pressure to low pressure, creating a wind within the pipe.

The amount of wind power generated by this system depends on the air pressure difference from the center of the collector to the surrounding land.

The sun is higher in the sky and gives more sunlight in the summer than in the winter.

The hot air rising from the center of the collector creates and maintains a low pressure area in the center of the collector. The pipes have a constant difference in air pressure from one end to the other. This difference in air pressure moves air through the pipes. Each pipe has pressure-staged wind turbines which present a kind of obstacle to the air movement. The wind turbines remove mechanical energy from the wind in the pipes and convert it to electricity.

WIND TURBINES

A series of very large wind turbines within the pipe turn the wind into electricity with a high 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 output the output would be increased by 40% by using one large wind turbine, instead of 7 smaller ones

CONCLUSIONThis type of system produce power Air must move from high to low pressure

through the air channel & wind turbines.Has not been built & tested to determine how

much power will be produced.Alternate Design:  to increase efficiency, place

air channel so that one end is over a large body of water. The water will be much cooler than the collector and will increase the air pressure difference along the air channel.
