1. The definitions of the two are different: a water conservancy project refers to a series of functions jointly performed by many buildings, which is called a hub. It may include reservoirs, dams, power plants, fishways, waterways, spillways, etc. , and the concept is the widest. Hydropower station is a power station project that uses hydropower to generate electricity. Usually, water conservancy projects with power generation as the main function are called hydropower stations.
2. The scope of the two is different, hydropower station is a kind of water conservancy control project, and the scope is very narrow; Water conservancy projects include reservoirs, dams, power plants, fishways, waterways and spillways. , the concept is the widest.
3. The purpose of the two is different: the water conservancy control project is a complex of different types of hydraulic structures built in the appropriate sections of rivers or channels to meet the objectives of various water conservancy projects. Hydropower stations are used to generate electricity.
According to the different tasks undertaken, water conservancy projects can be divided into flood control projects, irrigation (or water supply) projects, hydropower projects and shipping projects. The main factors affecting the function of the water control project are the selection of reasonable location and optimized layout scheme. The location of water conservancy projects is generally determined by river basin planning or regional water conservancy planning. The specific location must fully consider the terrain and geological conditions, so that all hydraulic structures are arranged on a safe and reliable basis, and can meet the scale and layout requirements of buildings and the necessary conditions for construction.
Extended data:
Present situation of hydropower generation in China:
China is rich in hydropower resources, with the total reserves ranking first in the world. 20 1 1 year has the highest hydropower generation in the world, with Europe accounting for 173% and the United States accounting for 2 1 1%. In 20 10 year, China's hydropower generation accounted for 10% of the world. According to the data of primary energy consumption structure in China in 2008, the proportion of hydropower, wind power and nuclear energy in China's total energy consumption is low, only 8.9%, so it is necessary to actively develop renewable energy.
Compared with other countries, it is an indisputable fact that the utilization rate of hydropower in China is low, so there is still a lot of room for hydropower development in China. However, the reservoir will cause irreversible damage to the environment, so the impact on the environment must be seriously considered. Moreover, it should be noted that the ratio of annual actual power generation to maximum power generation of hydropower units in China is 0.37, and the idle rate of hydropower units is higher than that of most developed countries.
