SYNOPSIS:
The combined power generation system is the title of the project, the title itself shows the way to unlock the thing hidden inside it.
The combined power generation system is the concept of combining or integrating the individual power generation system into a single system.
• The individual power generation systems are as follows.
1. Solar power generation system.
2. Hydroelectric power generation system
3. Wind power generation system.
These are the power generation system which generates the power by using naturally available resources i.e. renewable source of energies.
• Simple working of above power generation systems.
• Solar power generation system: This system mainly consists of solar panel, electrical wiring, battery and out let to the application.
Solar power is the conversion of sunlight into electricity, either directly using photovoltaic’s (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaic’s convert light into electric current using the photoelectric effect.
• Hydroelectric power generation system: In hydroelectric power plants the potential energy of water due to its high location is converted into electrical energy. The total power generation capacity of the hydroelectric power plants depends on the head of water and volume of water flowing towards the water turbine.
• Wind power generation system: It's hard sometimes to imagine air as a fluid. It just seems so ... invisible. But air is a fluid like any other except that its particles are in gas form instead of liquid. And when air moves quickly, in the form of wind, those particles are moving quickly. Motion means kinetic energy, which can be captured, just like the energy in moving water can be captured by the turbine in a hydroelectric dam. In the case of a wind-electric turbine, the turbine blades are designed to capture the kinetic energy in wind. The rest is nearly identical to a hydroelectric setup: When the turbine blades capture wind energy and start moving, they spin a shaft that leads from the hub of the rotor to a generator. The generator turns that rotational energy into electricity.
• Reason for selecting the combined power generation system as project: If we consider above power generation systems individually they are not reliable to supply the power for entire period in the year, because the power generation fluctuates it totally depends upon environmental conditions. I.e. for hydroelectric power generation, if the rain falls then only we will get proper rate of discharge of water for the power generation and in addition to that in summer sessions obviously discharge of water reduces, again it is variable factor.
For solar power generation, Here the sun light is the main source the for the power generation that also available in day time only, in addition to that chances availability of sun light in winter sessions is less and in other time it depends upon weather, again it is variable factor.
For wind power generation, It is mainly depends upon velocity of the fluid i.e. air flows over the blade, the rate of flow of air over the blades is proportional to power generation. It also depends upon the environmental condition, again it is also variable factor.
• Location of combined power generation system: This is the one of most important consideration in the entire project, That is there are several villages near the forest not seen the rays electric light because of it is too far away from the near electric connection available, i.e. carrying electricity is possible only by cabling and by metal wires with pole. But for small village it is very expansive and become uneconomical.
For these reason only we can’t simply leave without providing the proper solution to this problem, because every people’s has right to get the basic felicities. It is the duty of the government to respond in order to provide the proper solution to their problems. This project will be the one of excellent solution to solve this problem.
