A comprehensive engineering facility that converts water energy into electricity is a hydropower plant. It includes a series of hydropower buildings built to produce electricity using water energy and various hydropower station equipment installed.

The drop of the natural water flow in these buildings is used to form a head, collect and adjust the flow rate of the natural water flow, and transmit it to the turbine. Through the combined operation of the turbine and generator, the concentrated water energy is converted into electrical energy, and then the power energy is input into the power grid through transformers, switch stations, transmission lines, etc.

In addition to the buildings required for power generation, some hydropower stations often have other buildings that serve comprehensive utilization purposes such as flood control, irrigation, shipping, wood and fish. The complex of these buildings is called hydropower station hubs or water conservancy hubs.

These are all written in Baidu Encyclopedia information, but this is the first time Huangshi has personally entered the internal core of the hydropower station, and he is a little excited because it has fulfilled his dream when he was a child. When he was a child, he built such a small hydropower station in a small valley in his hometown. The water head is estimated to be more than 70 meters, but the installed capacity of power generation is probably not as large as this hydropower station.

Because the stream in my hometown is very small, the mountain is relatively high, and the water diversion pipe built from the mountain to the foot of the mountain is more than 60 meters high. Once he and a few children went to the hydropower station to play, but people did not allow them to enter the hydropower station factory. Someone suggested that we all follow the water diversion pipe at the foot of the mountain to the top of the mountain. When the children started, they naturally did not fear the weather and the earth, and they rushed to climb up one by one.

But halfway through the climb, several small stones were blown down from the mountain by the wind, smashing one of the children's heads. His loud crying sound caused Huangshi, who was climbing on him, to look down. He found that the hydropower station below was so small that he felt a little dizzy. From then on, he felt a slight fear of acrophobia in his heart.

Because there is a stone staircase about half a meter wide on both sides of the water pipe. The staircase extends upward at an angle of 60 degrees. Not only is there no railing on both sides, but there is not even a single iron lock like on Huangshan Mountain. The wind on the hillside is a bit rushing, and when they blow through their ears, they will make a whimper.

These children were in a dilemma. They saw that there was a height of thirty or forty meters below and a distance of more than thirty meters above. The wind seemed to pull people off the stone ladder. They could only lie there tightly, and then they seemed to have their strength been exhausted. In this way, the cry of a child turned into a chorus of all the children until the crying led out the staff in the hydropower station.

Although Huangshi and the others were then picked up by the staff in the hydropower station one by one from the water diversion pipe halfway up the mountain. Others didn't know what happened later, but after he returned home, he had a nightmare of stomping on the rolling rocks in the void for several days. When he grew up, if he saw that there were no strong railings outside blocking him, he would be weak and sweaty in his palms.

From then on, the hydropower station became a spiritual loophole, and he never dared to get involved again. Even when classmates from other places came to their homes to play, they would find various reasons to shirk them. Therefore, he had never seen the internal structure of the hydropower station before.

...

As soon as he entered the main factory, Huangshi thought he could see the turbine unit. Although he had seen N times on TV, he had never seen the specific objects, so he couldn't help but feel a little curious. However, he didn't know that the hydropower station was in front of the main factory, and a small exhibition room was specially separated by a glass door.

When I walked in, I saw a banner hanging on the wall on the left, which read "Welcome... the leader to guide... the installation and commissioning of the small hydropower station". Obviously, the leader had not left for a few days, otherwise the banner would have been pulled off long ago.

There is a booth in the middle of the glass, with glass frames covered on the booth, as if there are various yellow and traffic lights flashing inside. When Danwang approached, he saw that on the left was a small hydropower station with a scale reduction model, and on the right was a large sand table in the environment where the small hydropower station was located.

Look at the beautiful and vivid sand table, a hydropower station with green water, green mountains and white mountains. A silver stream lingers in the mountains. Finally, it was built on the other end of the waterfall and then a water diversion pipe was drawn from the dam. It was directly pulled into the power station at the foot of the mountain. Then there were several high-voltage line towers on the mountain next to it, and they were connected by high-voltage lines.

On the mountains on both sides of the hydropower station and in the blank space in the square in front of it, there are red paper-cut place names and factory names. The most interesting thing is that the space is left next to it, and the poem "Water tune song head. Swimming" is also pasted. Huangshi looked at it and felt that "cutting off the clouds and rain in Wushan, and the high gorges out of the flat lake" was quite appropriate, as for the others, haha.

The model made in proportion to the small hydropower station is even more vivid. It is divided into three layers: upper, middle and lower, representing the water diversion pipes on the upper part of the mountain, the hydropower station factory part in the middle, and the lower floor represents the turbine unit, water diversion channel, flood discharge channel and other parts at the bottom of the dam.

Although this exquisite model is made of transparent fiberglass, it was cut off a triangle like a cake on the side. Huangshi walked over to see it. It turned out that it was designed to allow visitors to see the internal situation of the factory more clearly.

"It's really interesting." Huang Shi laughed, bowed his head and looked at it with relish. It turned out that the various pipe wires in the model were represented by transparent hoses of different colors. Among them, there were tiny light bulbs stuffed into the water pipes that represented the direction of the water flow. What Huang Shi saw just now was that they were flickering, representing the endless water flow.

"Uh." Danwang didn't expect that a person as big as Huangshi would like a child, like these gadgets, and he looked at them with a gaze.

"Is this what you did for them?" Huang Shi stood up and asked Dan Wang. He saw that the model of the hydropower station was very practical, and each production step was marked very clearly, which shows that it was not a simple prop model, and it was different from the antique warship model that Qi Ye was working on. He had a solid process inside.

"Uh, it wasn't what we did." Danwang looked at Huang Shi as if he was serious, so he continued, "Then I'll ask them for you."

"Okay, thank you, haha."

"Old Huang, don't be so polite."

After a while, he went out to inquire and came back and said to Huangshi, "I asked them and said that there is a Liuyang River model production company in the province, which specializes in producing such models. Not only hydropower stations, but also wind farms, chemical plants, water conservancy projects, etc., all of them are available."

After saying that, he smiled and said, "I think you may use it. I also asked you about their address and phone number, so you can check it yourself." Then he handed a piece of paper to Huangshi, and wrote the address, phone number, contact person and other aspects of the model company, which was very detailed.

"Thank you so much." Huang Shi took a look, folded the paper in half, and then put it in his top pocket. Maybe this one will be used in one day.

"What's there to thank? Lao Huang, you are so kind."

Danwang shook his hand and then said to Huangshi, "By the way, Lao Huang, didn't you tell me to explain the basic knowledge of hydropower stations to you in the morning? Should you start now?"

"Okay, thank you so much. Tell me."

"Haha, look, what I just said is back, OK, then I'll start with the components of the hydropower station."

It turns out that reservoirs are generally water diversion systems, power plants, electromechanical equipment, etc. formed by water blocking and water discharge buildings. The high water level of the reservoir flows into the factory through the water diversion system to push the water wheel generator set to emit electricity, and then enter the power grid through the step-up transformer, switch station and transmission line.

Hydropower stations can be divided into four categories according to the nature of the water source used. One is a conventional hydropower station, also known as a dam-type hydropower station. The second is a Shilongba Hydropower Station, which uses natural rivers, lakes and other water sources to generate power. The third is a pumped storage power station, which uses excess power at low load troughs in the power grid to pump water from the reservoir at high places to the upper water reservoir for storage. When the load of the grid is peak, water is released to generate power, and the tail water is sent to the reservoir to meet the needs of power loads such as peak shaving of the power grid. The fourth is a tidal power station, which uses the potential energy of the water level difference generated by the rise and fall of the tide to generate power.

There are also two types of water-reserved hydropower stations that do not have reservoirs or small reservoirs, and reservoirs have certain adjustment capabilities. According to the regulation cycle of hydropower stations, reservoirs are divided into multi-year adjustment hydropower stations, annual adjustment hydropower stations, weekly adjustment hydropower stations and daily adjustment hydropower stations. Annual adjustment hydropower stations store water from the abundance of the year for power generation during the dry water period. The meaning of hydropower stations in other adjustment cycles is to store water from the abundance of the year for power generation during the dry water period.

According to the power generation head, it is divided into Gaoshuitou hydropower station, Zhongshuitou hydropower station and Lowshuitou hydropower station. There is no unified regulation for this in all countries around the world. China calls power stations above 70 meters of water head a high-shuitou power station, power stations at 70 to 30 meters of water head a Zhongshuitou power station, and power stations below 30 meters of water head a low-shuitou power station. According to the installed capacity, it is divided into large, medium-sized and small hydropower stations.

"It's so complicated." Huang Shi shook his head. After listening to the situation of the hydropower station that Danwang mentioned, this hydropower is really a major subject. He suspected that the people under his command had to accumulate many years of experience before they could build such a small hydropower station. I was afraid that it would not be possible to rely on his own stolen masters and the construction drawings.
