Description

TECHNICAL FIELD [0001] The present invention relates to a hydroelectric power generation system,

The present invention relates to a turbine or a power generation device that generates electricity by harnessing the energy of a position of a river or seawater. More specifically, The present invention relates to a hydroelectric power generating engine and a hydroelectric power generating method capable of generating electricity economically by rotating a power plant.

Hydropower is a method of converting the energy of water located in a high place into the kinetic energy of a generator turbine and obtaining electricity using the induction phenomenon inside the generator. The old spinning mill used to spin the spinning wheel away from the high water. Then, the water before the fall has a positive (+), positive height, so it has a positive potential energy. This potential energy changes as the kinetic energy of the spinning wheel by the mechanical energy conservation law when the water falls on the wing of the spinning wheel. The kinetic energy of this spinning wheel is the driving force for the baby. This is the basic principle of hydropower generation. However, in the spinning mill, only the conversion process between kinetic energy (transition from kinetic energy to kinetic energy) occurred, but in hydroelectric power generation, the process of converting the kinetic energy of the turbine into the form of electric energy is added again. For these hydroelectric power, we build a dam by blocking the river. It confines water upstream of the dam, opens the gate and drops it down the dam, turning the turbine. In this process, the kinetic energy of the water is converted into kinetic energy of the turbine. As the rotor coil inside the turbine rotates along the turbine, electromagnetic induction phenomenon occurs and current is generated. This process converts the kinetic energy of the turbine into electrical energy.

In the case of such hydroelectric power generation, in order to increase the generating capacity, the water has a large potential energy. Natural fall and natural flow are called hydrographic power generation, and the amount of power generation is influenced by terrain, season and rainfall. Therefore, damping power generation is used to maintain stable power generation and increase drift. Even if the dam is built, the generator can not operate continuously if the rain does not come to the upstream of the dam for a long period of time. Thus, in Korea, where precipitation is concentrated in summer, and water for power generation is lacking in other seasons, the country also uses amphibious power generation. This is a method of using the remaining power at night with low power consumption to draw the water that flows downstream of the dam to the upstream of the dam by using the pump, In Korea, amphibians are developing in Cheongpyeong, Muju and Samrangjin power plants. There is also a watershed-like development as a way to get bigger drops. This is a method of building a power plant by changing the flow of the existing stream to a direction of a big drop. Kangnung Hydroelectric Power Plant uses this method in Korea. However, these conventional hydroelectric power plants are not limited in size and can be applied to the civilian population of the submerged area due to the location selection, from the procurement cost of huge dam construction, maintenance of safety and maintenance after construction, securing of professional manpower necessary for operation of power plant, There are not a few issues to consider, such as the environmental problems, maintenance of adequate water level for development, and efficiency of development. In this regard, studies are underway to take into account the economic feasibility of construction and development in the future, to minimize the development anxiety of the fresh season, to minimize the damage to the surrounding environment, and to operate with minimum manpower. Particularly, effort and research are being made to efficiently generate a large amount of electricity at low cost.

4, when the upper water supply door 112 and the first and second upper supply door openings 124 and 125 are opened, fresh water or seawater flows into the upper water supply passage 111, the first and second upper supply passages 162 and 163 To the inside of the first and second water pressure tanks 20 and 30.

On the other hand, fresh water and seawater may be supplied to the upper water supply line 111 by separate power.

2 and 5, the lower water supply door 212, the first and second lower supply door openings 224 and 225 are opened to open the inside of the body portion 10 and the third and fourth water pressure tanks 40 and 50 . As a result, buoyancy is generated in the buoyant body 1 as the water rises in the third and fourth hydraulic tanks 40, 50 and the body 10, and the buoyant body 1 is raised. As the first and second weight bodies 22 and 32 interlocked with the buoyant body 1 press the filled water in the first and second water pressure tanks 20 and 30, Water filled in the tanks 20 and 30 is discharged through the first and second discharge paths 310 and 320. Water discharged at high pressure through the first and second discharge passages 310 and 320 generates electricity by rotating the turbine of the generator. Here, when the water is discharged through the first and second discharge paths 310 and 320, the first and second discharge door openings 312 and 322 are kept open under the control of the control unit.

Thereafter, when the third and fourth discharge door openings 332 and 342 are opened, water in the third and fourth water pressure tanks 40 and 50 is discharged to the high pressure by the pressing force of the third and fourth weight bodies 42 and 52 . That is, water in the third and fourth water pressure tanks 40 and 50 is discharged through the third and fourth discharge paths 330 and 340 by the pressurization of the third and fourth weight bodies 42 and 52. [ The water discharged at a high pressure through the third and fourth discharge passages 330 and 340 generates electricity by rotating the turbine of the generator. Here, when the water is discharged through the third and fourth discharge paths 310 and 320, the third and fourth discharge door openings 332 and 342 are kept open under the control of the control unit.

When the water is discharged through the third and fourth discharge paths 310 and 320, the buoyant body 1 is lowered and the upper water supply door 112 and the first and second upper supply door openings 124 and 125 are opened, The first and second water pressure tanks 20 and 30 are filled with water again.

The opening and closing of each door is controlled by a control unit. A position sensor for sensing the position of the buoyant body 1 and a water level sensor for sensing the height of the water level in the lower part of the body part 10 sense the flow of water and transmit the sensed result to the controller. This series of sensing and control can be adjusted to a minimum of personnel.

9, the first power generation step is performed while the first turbine 800 is rotated by the water sprayed from the first and second water pressure tanks 20 and 30, 4, the second turbine (900) is rotated by the water sprayed from the water pressure tanks (40, 50), and the second power generation step is performed. Here, the number of the turbines may be set as plural as required. In addition, a plurality of hydroelectric power generating engines (500) are provided, and the control unit controls the opening and closing states of the door openings, thereby controlling the descending timing of each weight and sequentially discharging the high pressure water discharged through the discharge passage. Accordingly, it is possible to rotate the turbines 800 and 900 of the generator by continuously discharging the high-pressure water even in a beam of a river having a low water level difference, so that efficient electric power generation can be achieved.

10, a plurality of hydroelectric power generating engines 500 are installed in a stepwise manner with a difference in height, so that water drained through a drainage passage of the preceding hydroelectric power generating engine 500 is supplied to the rear hydraulic power generating engine 200 There is an effect that sufficient power generation can be effected even at a small flow rate.

As shown in FIG. 11, the supply source for supplying water to the hydroelectric power generation engine may further include a storage space 550 for storing seawater using the difference between the tide levels, so that seawater can be used for hydroelectric power generation. Alternatively, a water source for storing fresh water may be provided and fresh water from a water source may be used for hydroelectric power generation.
