The Ertan hydroelectric power plant, county's administrative center, was completely relocated, resulting in largest hydroelectric power plant in country in 20th century.
China is a country with a vast territory and rich resources. In China, you can find every landscape on earth. The uneven surface has also brought China a lot of abundant resources to exploit and develop, as well as a rich tourist environment, praiseworthy attractions.
China's topography represents general characteristics of being high in west and low in east. Due to huge difference in relief in China, a series of numerous strange mountains and waters have formed. The water flow in river, especially large river differential is relatively large, which is conducive to development.
Rivers with a large fall can produce rich hydroelectric resources. As long as hydroelectric power plants are built in canyons rich in hydropower resources, hydropower resources can be used to generate electricity, and then energy resources can be connected to national grid, and people can use hydropower resources.
Therefore, China, as a large country with "infrastructure madness", has built many large hydroelectric power plants. Today we will get acquainted with Ertan hydroelectric power plant, largest hydroelectric power plant in China in 20th century.
1. Acquaintance with Ertan hydroelectric power station
Ertan Hydropower Plant is a frontier hydropower plant in China. It is located in Panzhihua City, an industrial city in Sichuan Province, China. It is located at intersection of two small counties Miyi and Yanbian in southern China. outskirts of Panzhihua City, at same time, it has resources of water system of Yalong and Jinsha rivers, and is an area with extremely rich water and energy resources.
Because it is located between geological regions of Hengduan Mountains, the terrain is very undulating and canyons are deep, which is very suitable for construction of large hydroelectric power plants. The mountains and rivers here are beautiful, with high mountains and meandering rivers.
Because latitude is low, it is mild and humid all year round, which is very suitable for tourism. The lush mountain jungle scene made a very deep impression on drivers, and edge of road along road is a deep canyon, like a bottomless pit.
The project of this large-scale power plant is mainly for power generation, supporting industrial development and additional energy consumption in nearby industrial cities, and it is supplemented by tourism income, both benefits of integrated use, very efficient use of this large HPS. How big can this hydroelectric power plant be?
This is more expensive than China's most famous Three Gorges of Yangtze River. It is power plant with highest investment in China in last century. It took 9 years to complete construction of all facilities of entire hydropower industry. station.
From beginning of planning and construction to first successful generation of electricity for this hydroelectric power station and use of electricity in industry, seven years have passed, which is enough to show its scale and how much it consumes labor and material resources.
This hydro power plant is not only an industrial hydro power plant for converting water energy resources into electricity, but also a very spectacular and important national scenic spot. Ertan hydro power plant is part of Ertan National Forest Park.
It is also one of most important tourist attractions in this national forest park and selling point of a major tourist resource. After construction of Ertan HPP, a large artificial lake was built next to HPP.
Subsequently, due to long-term flooding of land, original shape of land gradually changed, and several natural lakes were naturally formed, which are worth visiting for tourists.
It is also true that Ertan hydroelectric power plant has also become an important part of famous "Shangri-La Ecosphere", playing an important role in maintaining water sources for this ecosphere.
2. The complexity of construction of Ertan hydroelectric power station
The cost of this century-old project exceeds all our expectations. There are thousands of people in construction team alone, and up to 600 people in team of specialists. You should be aware that if you want to build a large hydroelectric plant, land in surrounding area will be flooded and covered, which requires use of a certain area of the resettlement plan.
Since ancient China "lived by water", yes, as an ancient agricultural country, source of water is certainly a prerequisite for cultivation of crops by ordinary people, so when ancestors chose a settlement and a place to settle, they are often close to source of water, and same is true for people in Miyi and Yanbian areas.
However, construction of a hydroelectric power plant requires construction of a large-scale reservoir capable of storing a large amount of water resources. This requires demolition of land so that water in reservoir can only be stored when it is flooded, to facilitate normal operation of hydroelectric power plant in future. Therefore, the entire Yanbian County will be moved to a new location within a few years, a huge cost and complexity can be imagined!
Moving into a new home is very difficult for people these days, and it takes a lot of energy and money to prepare for week. However, if you want to relocate whole district, it is related to daily life. how many people!
The original old Yanbian County is now completely flooded by Ertan Hydropower Reservoir. People have also paid a huge price and sacrifice for this project. The victim of construction of hydroelectric power plant now seems to have received great rewards and benefits, and natives of original Yanbian are also living a stable and happy life in new area of the city.
