INTRODUCTION TO HYDROPOWER

Hydro means "water". Hydropower is "water power" and

hydroelectric power is electricity generated using water power.

Egyptians harnessed energy from flowing water 2,000 years ago

Hydropower is the most widely available renewable energy

19% of all electricity used around the world

18/22

PROTECTION SCHEME

I. PROTECTION FROM INTERNAL FAULTS

II. PROTECTION WITH EXTERNAL FAULTS


19/22

MERITS

i. Renewable source of energy thereby saves scares fuel

reserves.

ii. Economical source of power in long run.

iii. After the setup has been done the generation cost is low ascompared with other energy sources.

iv. Higher efficiency 95% to 98%.

v. Fuel is not burned so there is minimal pollution.

vi. Water to run the power plant is free.


20/22

DEMERITS

i. Susceptible to vagaries of nature such as draught.

ii. Longer construction period and high initial cost.

iii. Loss of large land due to reservoir.

iv. Non-availability of suitable sites for the construction of dam.

v. Displacement of large population from reservoir
