"Hydroelectric Power Station" PPT Courseware 2

Humanity and Energy

Human survival and development are inseparable from energy. What energy sources are around us? Please look for it.

importance of energy

As modern people, we have adapted to a life that utilizes various energy sources. What would your life be like without electricity?

Various energy sources can be converted into each other, such as wind energy can be converted into electrical energy, thermal energy can be converted into electrical energy, solar energy can be converted into electrical energy, etc.

Utilization of water power

Human beings discovered the power of water very early on. So how do we use water power?

Water flow makes great achievements

People in the past used it to drive stone mills and spinning machines.

2. Characteristics of hydropower generation

Advantages: Hydropower is a renewable energy source, has less impact on the environment, has high power generation efficiency, low power generation cost, fast power generation start, can complete power generation within a few minutes, and is easy to adjust.

shortcoming:

Limited by natural conditions;

The one-time investment is large, there are many immigrants, and the construction period is long;

The consequences of the accident are serious;

Large-scale projects have a greater impact on the environment and ecology.

2. Characteristics of my country’s water energy resources

Feature 1: Rich in total volume and insufficient development

The total developable amount ranks first in the world, accounting for 16.7% of the world's total.

By the end of 2008, the installed hydropower capacity reached 165 million kilowatts, accounting for 30% of the technically exploitable capacity, which is lower than the average level of 60% in developed countries.

In the east, more than 70% has been developed

Feature 2: Uneven regional distribution and mismatch with economic development

The eastern region (13 provinces and municipalities) accounts for 8% of the country’s total hydropower resources, the central region (6 provinces) accounts for 11%, and the western region (12 provinces, municipalities, and autonomous regions) accounts for 81%;

But 51% of electricity consumption is in the east.

Three Gorges Hydropower Station

The most difficult water conservancy project in the world to construct.

It is the water conservancy project with the largest flow during the construction period.

The floodgate with the largest flood discharge capacity in the world.

The world's largest and most difficult ship lift.

It is the resettlement construction project with the largest number of immigrants and the most arduous workload in the world.
