Project Title

Solar Power Stand Alone DC Micro Grid System

Project Area of Specialization Electrical/Electronic EngineeringProject Summary

The solar chimney or the solar draft tower is the emerging technology now a days and in the future this technique provides the electrical power to the world in affordable prices. The principal of working if this “chimney” is quite simple is to just a combination of the collector glass and the tower which act like a chimney to exhaust the hot air absorbs from the sunlight in the form of a heat [1].

The solar chimney or the solar draft tower consist of the one green roof collector which is normally made up from the glass and the on exhaust unit for the heat absorbed by this chimney this is known as the collector which is made up from the plastic or a glass material [4] . The chimney is made from the solar chimney also used in the house ventilation and in crops proposes. Solar chimney also used to increase the indoor ventilation of the houses to increase the comfort level of the inhabitant’s.

Those countries which have a hot climate is the ideal for the solar chimney power plant and this is the environment friendly technique by which we can make the green electrical power in “megawatts” for the domestic purposes and also for the low level industries.

Towers do not need cooling water like other thermal power planst. This can be a key advantage in several sunny nations that have already main problems with capability by this technique we can easily save the huge amount in the aspects of the fuel and operating cost for the plants

Project Objectives

The main objetive and research behind this project is to decrease the load on the utility grid by generating the electrical power by the renewable energy sources. The current power sources are not enough to cope with the demand of the consumers to overcome this problem the proposed idea is presented for the generation of the green energy

Project Implementation Method

Implementation method is simple as a solar updraft power plant (SUPP) consists of the collector area, the turbine(s) with coupled generator(s) as power conversion unit, and the solar chimney. In the collector area, a large glass-covered area, wide-banded solar radiation heats the collector ground and consequently warms up the air inside the collector area, through the mechanism of natural convection. The buoyant air rises up into the chimney of the plant, thereby drawing in more air at the collector perimeter and thus initiating forced convection which heats the collector air more rapidly. The driving force or potential that causes air to flow through the solar tower is due to the pressure difference between the column of cold air outside and the column of hot air inside the chimney. The power conversion unit is at the foot of the tower. There, as the collector air flows across the turbines, the kinetic energy of the air turns the blades of the turbine which in turn drives the generators, so that the energy in the stream of warm air is transformed into electric power.

Benefits of the Project

The main advantage of solar updraft is that it doesn't need sunlight to operate, just warm air, so it continues to churn out power after sundown Unlike conventional power stations (and also some other solar-thermal power station types), solar updraft towers do not need cooling water. This is a key advantage in the many sunny countries that already have major problems with water supply.

The building materials needed for solar updraft towers, mainly concrete and glass, are available everywhere in sufficient quantities. Solar updraft towers can be built now, even in less industrially developed countries. The industry already available in most countries is entirely adequate for solar updraft tower requirements.

Even in less developed countries it is possible to build a large plant without high foreign currency expenditure by using local resources and work-force; this creates large numbers of jobs while significantly reducing the required capital investment and thus the cost of generating electricity.

Technical Details of Final Deliverable

We know that the green power generation is the desire of every country for the generation of green power.

Solar updraft towers are particularly suitable in countries with a warm climate and could be attractive for production of electricity for remote regions in developing countries. In particular, in countries where there large areas of degraded or low-value land is available for building the heat collectors.
