Description

A rural ecological hydroelectric power generation system

technical field

The invention relates to a power generation system, in particular to a rural ecological hydroelectric power generation system.

Background technique

Modern life and production are inseparable from electricity. However, coal-fired thermal power is still the main method at present. The electricity used is converted from mineral energy coal into steam energy for power generation. The electricity obtained is only about one-third of the coal-fired energy, which produces a large amount of greenhouse gases CO ₂ and SO ₂ , CO, NO _x and unburned hydrocarbons damage the earth's ecological environment. Second, about two-thirds of the energy is lost in the process of converting coal into electricity. There is also loss in long-distance transmission, and the investment is huge .

In the field of clean energy, the current hydropower projects and wind power projects require huge investments, especially hydropower projects that require interception and dams to store water, which have a great impact on the natural ecology, and even lead to the extinction of aquatic species, and are also prone to dam collapses that cause damage to people's lives and property loss. On the other hand, my country has a vast territory and complex topography. There are countless mountain streams, dams, and ditches in the vast villages and mountain villages. Thousands of rivers belong to the sea, and the total water flow of countless ditches, dams, and streams is far greater than that of large rivers. total kinetic energy. At present, under the circumstance that almost all the kinetic energy of streams, canals, and canals are wasted in different regions and landforms, many villages or mountain villages still suffer from power outages all year round, causing many inconveniences to the modern life and income generation of many rural people.

For this reason, many villages have spontaneously raised funds to build dams to store water for power generation, and local governments are also constantly planning to set up sites for damming and power generation. However, this kind of damming and water storage power generation project destroys the natural ecological environment of the original ecological stream, floods the precious arable land, and destroys a large number of natural ecological landscapes; Third, it is greatly affected by the rainy season and dry season, and the power and voltage of the generated hydropower fluctuate greatly with the water flow, which affects the safe use of electrical appliances; moreover, the cascade kinetic energy utilization rate of the original streams and ditches is too low, and most of the water Kinetic energy is lost during the water storage process, especially a large amount of kinetic energy of cascaded streams is completely lost through the damping of the dam body. At the same time, water storage and damming have also seriously affected the income of some farming and animal husbandry villagers, and brought the potential risk of dam failure to the safety of people's lives and properties downstream.
