Construction and Working of Tidal Power Plant


                The Extraction of potential energy Involves building a barrage. The barrage traps a water level inside a basin. Head is created when the water level outside of to basin changes relative to the   water level inside. The head is used to drive turbines. In any design this leads to a decrease of tidal range. Inside the basin, implying a reduced transfer of water between the basin and the sea.
This reduced transfer of water accounts foot the energy produced by the scheme.

       The dam have large gates in it and for storing water in the storage basin the gates are opened at the time of high tide and after storing Water the gates are closed. After the tide has receded, the water is allowed to flow back to the ocean through water turbine. Thus the tidal energy stored at Height can be utilized to drive a turbine coupled to an electric generator, which generates Electrical power. Buy using reversible water turbine the turbine can run Continuously both during high tide and low tide. The Principle of operation is il
lustrated.

Tidal Power

Tidal Power


The Tidal is the regular rising and falling of the ocean’s surface caused by changes in gravitational forces external to the earth. The primary changing gravitational field is due to the moon while the secondary field is caused by the Sun. The maximum water level is called high tide; the minimum level is low tide. The time between high tide and low tide is called EBB or falling tide, the time between low tide and high tide is called flow, flood or Rising tide. At any given point on the ocean, there are normally two high tides and two low tides each day. On average, high tides occur 12 hour 24minutes apart. The 12 hours is due to the Earth’s rotation, and the 24 min to the Moon’s or bit.


The Tidal Power is a means of Electricity generation achieved by Capturing the Energy Contained in moving water mass due to tides. Two types of tidal Energy can be extracted. Kinetic energy of current due to the tides and potential energy from the difference in height between high and low tides.

Solar Panel

How Sun Tracking Solar Panel Works?

Ans;-Initially power the circuit.
Place the set up in dark
When the two LDRs are in dark, there is no movement in the panel.
Now place a torch in front of the left LDR. Panels slowly move towards its left.
Now move light from left to right. You can observe the panel moving slowly with the torch towards right.
In the middle, when intensity on both LDRs is equal, panel will not move until there is difference between the light intensity falling on the LDRs.




What The Advantages of Sun Tracking Solar Panel?

Ans:-The solar energy can be reused as it is non renewable resource.
This also saves money as there is no need to pay for energy used.


what the  Applications of Sun Tracking Solar Panel?

Ans:-These panels can be used to power the traffic lights and streetlights
These can be used in home to power the appliances using solar power.
These can be used in industries as more energy can be saved by rotating the panel.
Limitations of Sun Tracking Solar Panel Circuit:

Though solar energy can be utilized to maximum extent this may create problems in rainy season.
Although solar energy can be saved to batteries, they are heavy and occupy more space and required to change time to time.
