China News Agency, Lanzhou, April 1 (Ai Qinglong came to Chunmei) China's first million-kilowatt hydropower station, Liujiaxia Hydropower Station, celebrated its 53rd anniversary of power generation on April 1.
As of March 31, 2022, the cumulative power generation of Liujiaxia Hydropower Station was 258.7 billion kWh, which is equivalent to saving 90.405 million tons of coal, reducing carbon dioxide emissions by 236.8611 million tons, and reducing sulfur dioxide emissions by 768,400 tons.
Liujiaxia Hydropower Station is built on the main stream of the Yellow River in Yongjing County, Linxia Prefecture, Gansu Province. It has created seven firsts in China, including the highest concrete gravity dam, the largest single-unit capacity of dual water internal cooling, and the highest voltage level transmission line.
When it comes to the Yellow River, water and electricity are inseparable.
The "goodness" of hydropower begins with generating electricity.
The flood-damping dam of Liujiaxia Hydropower Station is 147 meters high, and "holds together" the dangerous peaks on both sides of the gorge. It raises the upstream water level, causing a drop of 100 meters, allowing the Yellow River water to generate powerful electricity through the hydro-generator.
Fu Tingqin, director of Liujiaxia Hydropower Plant, accepted an interview with a reporter from China News Agency on the 1st. Before the completion of Liujiaxia Hydropower Station, there were only three isolated small and medium-sized power grids in Gansu. , and initially formed the framework of the Northwest Power Grid in Shaanxi, Gansu, Qinghai, and Ningxia provinces with Liujiaxia Hydropower Station as the backbone.
Liujiaxia Hydropower Station is not only responsible for peak regulation and frequency regulation of the Northwest Power Grid, but also related to the "double rise and double drop" and clean energy consumption of the Northwest Power Grid.
Li Pingdong, Secretary of the Party Branch of the Operation Branch of Liujiaxia Hydropower Station, said that the completion of the hydropower station not only created a precedent for China to eradicate the floods of the Yellow River and develop water conservancy in the Yellow River, but also connected the power grids of Shaanxi, Qinghai and Gansu provinces, and also contributed to the development of industry and agriculture in the northwest region. make a contribution.
Every April, 800 million to 1.2 billion cubic meters of water is replenished for spring irrigation in Gansu, Ningxia, and Inner Mongolia, so that more than 16 million mu of land along the lower reaches of the Yellow River can be moistened in time, which will help increase the yield per unit of grain.
As the second water source in Lanzhou, the Liujiaxia Reservoir draws water from the reservoir to 550 million to 830 million cubic meters each year, ensuring that 3.8 million people in Lanzhou realize the transition from “water to drinking”.
With the development of tourism on the Yellow River, Liujiaxia Hydropower Station, as an important symbol of modern civilization, has become one of the main tourist attractions in the area. You can not only see the landscape of the Yellow River flowing westward, but also the spectacle of "clear distinction between Jing and Wei".
