Description

Multi-layer hydroelectric power generation system {HYDROELECTRIC POWER GENERATING SYSTEM}

The present invention relates to a multi-layer hydroelectric power generation system. More specifically, it can generate hydroelectric power in valleys and rivers, as well as increase electricity production through efficient power generation even in places where water resources are not abundant, especially with low energy consumption. It is about a multi-layer hydroelectric power generation system that can continuously produce a lot of electricity.

As shown in FIG. 1, a hydroelectric power generation device refers to a power generation method that obtains electricity by converting the potential energy of the water into the kinetic energy of the generator turbine 20 by using the drop of water located at a high place through the waterway 10. .

It refers to power generation using the power of water, and refers to a method of obtaining electricity by operating a generator through a turbine rotated by flowing water.

Hydroelectric power is divided into several types depending on how it is operated.

First, the method of using natural drops or natural flow is called canal-type development, which is greatly influenced by topography, season, rainfall, etc. In order to compensate for this and maintain stable power generation and increase headfall, most hydroelectric power generation methods today are generated through the construction of dams.

Korea, which has few mountainous areas with steep slopes and large seasonal variations in precipitation, is generally unfavorable for hydroelectric power generation. Accordingly, methods are being attempted to overcome these natural conditions, a representative example of which is pumped water development. This is a method of using the remaining power at night, when power consumption is low, to pump the water flowing downstream of the dam back upstream of the dam, and then use it again for power generation during the day. In addition, there is basin change type power generation, which is a method that utilizes the topographical characteristics of Gyeongdong Province of east high and low low. This is a method of building a power plant by changing the flow of an existing river to a direction with a large drop. Representative examples include the Seomjingang Hydroelectric Power Plant and the Gangneung Hydroelectric Power Plant.

Hydroelectric power generation has the advantage of generating electricity using flowing water in natural conditions, causing no pollution during the power generation process, and no raw material costs required for power generation. However, in order to be economically feasible, difficult location conditions are required, such as an area with a large water drop and abundant flow, and the initial construction cost is high. Additionally, large-scale dams are generally required to increase power generation capacity, and environmental problems may arise due to the construction of large-scale dams. A large submerged area will be created in the new upstream lake created by the dam, and if the lake is large, it will also affect the local climate, such as frequent occurrence of fog. In addition, ecological side effects such as the disconnection of natural rivers may occur.

On the other hand, in cases where conditions are not as large as a dam, for example, in the case of a river, power generation may be achieved in the manner shown in Figure 2. However, the condition shown in Figure 2 corresponds to the case where water resources are abundant, and if water resources are not abundant, there is a problem in that power generation is difficult or the amount of power generation is insufficient compared to the facilities, which reduces effectiveness.
