2. Introduction (mat lab) MATLAB is a software used for solving mathematical problems, analyzing data, and creating visualizations. It’s widely used in fields like engineering, science, and finance. With MATLAB , you can perform complex calculations, plot graphs easily. It offers a user-friendly interface and extensive documentation, making it accessible for beginners and experts alike. MATLAB is essential for tasks ranging from academic research to industrial applications.

3. Introduction (Hydro power) Ancient Greek farmers have used water wheels to grind wheat into flour.
In the early 1800’s, American and European factories made use of the water wheel to run machines. In the late 19 th century, hydropower was used for generating electricity.
Waterwheels and mills were used for irrigation and mining.
Hydropower was the foremost source of energy for new inventions.

4. Role & Working of hydro power Hydropower typically works Water Collection : The process begins with the collection of water from a river, stream, or reservoir. This water is directed towards the hydropower plant through intake structures, which may include gates or screens to regulate flow and filter out debris. Penstock : Once inside the plant, the water flows through a penstock, which is a large pipe or tunnel. The penstock directs the water to the turbine with controlled pressure and velocity.

5. Turbine : As the water passes through the penstock, it strikes the blades of a turbine, causing them to rotate. The turbine is connected to a generator, which converts the rotational energy into electrical energy. Generator : The rotating turbine shaft turns the rotor of the generator within the powerhouse. This rotation induces an electromagnetic field within the generator’s stator, producing electricity through electromagnetic induction.

6. Transmission : The electricity generated by the generator is sent to a transformer, which increases the voltage for efficient transmission over long distances. The electricity then travels through transmission lines to reach homes, businesses, and industries. Return Flow : After passing through the turbine, the water exits the powerhouse and is released back into the river or reservoir through a discharge channel. This return flow may undergo treatment to remove sediments or other pollutants to minimize environmental impacts.

7. Control Systems : Throughout the process, various control systems monitor and regulate the flow of water, turbine speed, and electrical output to ensure safe and efficient operation of the hydropower plant.

9. Turbine and it’s working Turbine :like a big fan turned by water, steam, or wind. When the turbine spins, it’s connected to a generator. This spinning motion generates electricity by moving magnets past coils of wire inside the generator. So, basically, the turbine makes the generator create electricity by spinning it around.

11. Generator A generator is a device that converts mechanical energy into electrical energy through the principle of electromagnetic induction. It typically consists of coils of wire rotating within a magnetic field, causing a flow of electrons and generating an electric current. Generators are essential components in power plants and various applications where electricity is needed.

12. Visualization of electricity generate by generator

13. principal of working of generator / generation of electric city The principle behind generating current using mechanical energy in a generator is electromagnetic induction . When a conductor (such as a coil of wire) is moved within a magnetic field, it induces a current to flow in the conductor. In a generator, mechanical energy (often from a turbine or engine) is used to rotate a coil of wire within a magnetic field, producing electric current.

14. Energy transmission Transmission: In the context of energy, refers to the process of moving electrical power from its source, such as a power plant, to consumers, typically through a network of power lines and substations. Transmission systems are designed to efficiently transport electricity over long distances with minimal loss. In a hydro power plant, electrical energy is transmitted using power lines, also known as transmission lines. These power lines are usually made of conductive materials such as copper or aluminum and are supported by towers or poles.

15. The electricity generated by the hydro power plant is sent through these transmission lines to substations, where it may be stepped up or stepped down in voltage before being distributed to homes, businesses, and other consumers

16. Visualization of transmission and distribution of electricity

17. Energy distribution Finally, the electricity is distributed to homes, businesses, and other consumers through local power lines.

18. advantages Water is a renewable energy source. Maintenance and operation charges are very low. The efficiency of the plant does not change with age.
In addition to power generation, hydro-electric power plants are flood control, irrigation purposes, fishery . Also have a longer life(100 to 125 years)
Since hydro-electric power plants run at low speeds (300 to 400 rpm) there is ne requirement of special alloy steel construction materials or specialized mechanical maintenance

19. disadvantages The initial cost of the plant is very high. Since they are located far away from the load center, cost of transmission lines and transmission losses will be more. During drought season the power production may be reduced or even stopped due to insufficient water in the reservoir. Water in the reservoir is lost by evaporation.
