Is Xiaolangdi Hydropower Station bigger or Sanmenxia Hydropower Station bigger?

It is the scale of Xiaolangdi hydropower station.

1, Xiaolangdi Hydropower Station

The total installed capacity of Xiaolangdi Hydropower Station is 6.5438+0.8 million kilowatts, and the average annual power generation for many years is 4.599 billion kilowatt hours /585. 1 100 million kilowatt hours (/before kloc-0/0/after kloc-0/0).

Xiaolangdi dam is a rockfill dam with inclined core wall. The designed maximum dam height 154m, dam top length 1667m, dam top width 15m and maximum dam bottom width of 864m. The opening and filling amount of dam body is 5L. 8500 m3, the foundation concrete cutoff wall is l.2m thick and 80m deep. Its filling quantity and concrete cutoff wall are the highest in China. The crest elevation is 28 1m, the normal water level of the reservoir is 275m, the water area of the reservoir is 272km2, and the total storage capacity is12.65 billion m3.

2. Sanmenxia Hydropower Station

Sanmenxia Hydropower Station has an installed capacity of 450,000 kilowatts and an annual power generation of 1.7 1 100 million kwh.

1985 Sanmenxia Hydropower Station Phase II Reconstruction 1 No.8 Bottom Outlet, No.9 and 10 Construction Diversion Bottom Outlet were opened for reconstruction to expand the discharge capacity of the hub. Now, in order to further improve the power generation efficiency and restore the original units 6 and 7, two Francis turbine generators with a single unit capacity of 75Mw are being reinstalled, so that the installed capacity of the hydropower station will reach 400MW and the average annual power generation for many years will reach131.700 million kW h.

Debate on the Existence and Abolishment of Sanmenxia Hydropower Station

From August 24th to June 5th, 2003 10, the worst flood occurred in the Weihe River Basin in more than 50 years. 654.38+008 million mu of crops were affected, and 2.25 million mu of crops were not harvested. The flood caused many executions, dozens of people died, 510.5 million people were affected, and the direct economic loss reached 2.3 billion yuan.

Therefore, in June+10, 5438, the Ministry of Water Resources organized and held the "Special Investigation Meeting on Tongguan Elevation Control and Sanmenxia Reservoir Operation Mode" in Zhengzhou. Suo, Vice Minister of Water Resources, said at the meeting: "The Sanmenxia Reservoir has achieved great benefits after its completion, but this is at the expense of the interests of the reservoir area and the Weihe River Basin. The Weihe River has become a suspended river, and the main responsibility lies in Sanmenxia Reservoir. "

On February 4th, 2004, 15 Shaanxi Provincial People's Congress deputies proposed that Sanmenxia Reservoir should stop storing water. On March 5th, members of Shaanxi CPPCC jointly submitted a proposal to the Second Session of the 10th CPPCC, suggesting that Sanmenxia Reservoir immediately stop storing water to generate electricity, so as to completely solve the Weihe River flood.
