This picture indicates a process how flow
of water could change to other energy, water is used to produce electricity by a hydroelectric power
station.
At first, water goes down to the high-level
reservoir through a river. This reservoir can flow (흐르는 대상은 물이지, 저수지가 아닙니다.) at the day compared with the
situation of night because the dam does not let water go. Secondly, water flows
to generators which are machine that could make electricity (이런 거 설명할 필요는 없습니다~). In the day, water
arrives at reversible turbines that decide to activate generator or not. Once
the turbines operate generator, energy of water becomes electricity in power
station. At the next step, this electricity is conveyed through power lines.
Finally, it reaches national grid, and then people could use this electricity
made of water.
In this diagram, there are significant
differences how to operate during the day or the night. When it is the day, water
could reach generator. It means that water could make electricity. Meanwhile, the
dam blocks the reservoir. It means that water could not make electricity compared
with the day. Furthermore, there is a difference how turbines work also. During
the day, turbines make generator operate to change the power of water to electricity
that people can use. On the other hand, turbines play a role to send water into
the reservoir in the night. (이 문단은 일부 내용을 지워서 간추린 다음에 다른 내용을 넣어주셔야하는데, 총평에서 말씀드리겠습니다.) |
