The 16 production units of 1,000,000 kilowatts of the Baihetan hydroelectric power station have been

The last one million kilowatt unit (No. 9) of Baihetan Hydropower Station successfully passed waterless joint debugging and entered the commissioning and operation phase, marking the completion of the installation of the 16 million kilowatt units. -kilowatt units of the hydroelectric plant and on the way to the goal of full exploitation Start the final sprint.

The 16 production units of 1,000,000 kilowatts of the Baihetan hydroelectric power station have been installed. What are the technical difficulties behind the project?

1. It takes a long time and is difficult to build

The construction of the Baihetan Hydropower Station took 11 years. The river is very turbulent and the terrain is relatively rugged. The summer temperature in Baihetan is above 43 degrees, the surface temperature can reach 70 degrees, and the wind is very strong for more than 240 days. level 7, and the maximum wind can blow up to level 13. To put things in perspective, it can blow over a car. Additionally, mudslides are very likely to occur during the rainy season. Baihetan is located in the Hengduan Mountains. Its geological conditions are relatively complex and it is also surrounded by earthquake-prone areas. necessary to build such a high arch dam. On-site construction plan is very difficult and many challenges will be encountered during the construction process.

2. Super energy conversion

The key to hydroelectric power plants lies in energy conversion. Imagine that when the water rolling in the upper reaches of the Jinsha River continuously pours into the turbine through the steel pipe under pressure, forming a huge vortex, driving the turbine wheel to rotate at high speed, the energiThe potential of water is converted into rotational energy. mechanical energy, which is the most critical factor for the unit to produce electricity. Then the rotor drives the generator rotor on the turbine to rotate at high speed, thereby converting mechanical energy into electrical energy. One million units means that when a single unit is operating at full load, it can produce up to 1 million kilowatts of electricity per hour. Take Deyang City, Sichuan Province, where TEPCO is located, as an example. A production unit of one million units can generate electricity at full capacity for 365 days, which can meet the electricity demand of Deyang City for a whole year.

Postscript: What you see is that the hydroelectric plant is desperately releasing water, but it is actually tight at the upper limit of the flow that the downstream can handle, and the wavess of floods are contained in its belly, thus avoiding “floods that the downstream cannot withstand”. This effect is called “clipping” in hydraulics. How do you say that? How can there be peace in the years, just because there is a great reservoir that silently bears the burden downstream?
