Hydropower, or hydroelectric power, is a renewable energy source that generates electricity by using the kinetic energy of flowing water:
1. Store water
Water is collected or stored at a higher elevation, such as in a reservoir created by a dam.
2. Release water
The water is released through pipes or tunnels (penstocks) to a lower elevation.
3. Turn a turbine
The falling water pushes against and turns the blades of a turbine.
4. Generate electricity
The turbine turns a metal shaft in an electric generator, which produces electricity.
5. Step up voltage
Transformers convert the alternating voltage to a higher voltage for long-distance transmission.
6. Feed into the grid
The electricity is fed into the electrical grid to power homes, businesses, and industries.
The amount of electricity a hydropower plant can produce depends on:
Water flow: The greater the water flow, the more electricity the plant can produce.
Head: The change in elevation, or fall, from one point to another. The higher the head, the more electricity the plant can produce.
What is a hydroelectric power plant, and how does it work ...
Hydropower is the largest and cheapest renewable electricity source globally. It generates about 15% of global electricity and provides at least 50% of the total electricity supply for more than 35 countries.

水力发电,或称水力发电,是一种利用流动水的动能发电的可再生能源:
1.储存水
水在较高海拔处收集或储存,例如水坝形成的水库。
2. 放水
水通过管道或隧道(压力管道)释放到较低的高度。
3. 转动涡轮机
落下的水推动并转动涡轮机的叶片。
4. 发电
涡轮机转动发电机中的金属轴,从而产生电力。
5.升压
变压器将交流电压转换为更高的电压以进行长距离传输。
6. 馈入网格
电力被输入电网为家庭、企业和工业供电。
水力发电厂的发电量取决于:
水流量:水流量越大,发电厂可产生的电力就越多。
头部:从一点到另一点的高度或下降的变化。水头越高,发电厂可产生的电力就越多。

水力发电是全球最大、最便宜的可再生电力来源。它生产全球约15%的电力,并为超过35个国家提供至少50%的总电力供应。
