Abstract

According to the present invention, a rotor coupled to a turbine providing rotational force, and a generator stator and a generator rotor wound with a coil are disposed, an excitation current (122) flows through the rotor disposed in the generator to increase or decrease the magnetism of the rotor when the connected turbine rotates, thereby controlling the output/voltage/current/frequency of the generator to the turbine flow rate to produce reactive power. The generated reactive power and active power are transmitted into a transmission system and the power generation output is transmitted to the system.

Description

Pressure Pump type Hydraulic power generator using the seawater}

The present invention relates to continuous power generation using seawater as a power source, and is a hydroelectric power generation device using seawater that converts wave intensity pressure energy according to horizontal movement to seawater into electric energy by driving it freely.

The water intake part 111 is located in the sea, and the nadeoji part is located on the land. Therefore, seawater is drawn in from the sea and supplied to the land.

Here, the water intake unit 111 is preferably located at a height lower than the height of the ebb tide at sea level. In the water intake part 111, the seawater flow rate due to the tidal current and the seawater flow rate due to the tidal phenomenon are accelerated, and the seawater flows into the interior. Since the direction of seawater may be changed according to tidal currents or tidal phenomena, the direction of the head (not shown) in which seawater flows into the water intake unit 111 is provided and installed in a structure in which seawater flows in all directions according to the flow of seawater. . In this way, since the water intake unit 111 is located at a height lower than the height of the sea level, the quantity of seawater can be secured for 24 hours, and the seawater required for electricity production can be supplied for 24 hours by using this.

In order to convert the potential energy of seawater introduced from the water intake unit 111 into kinetic energy, it maintains the level of the ocean and always has the pressure pump room.

The conversion unit 115 opens the starting valve 116 to use the free fall kinetic energy and operates the pressure pump. Of the high pressure introduced into the power generation unit 120

The flow rate is opened to the water turbine control valve 118 to enter the water turbine operation.

Drainage part 126 When the discharge pipe 123 is discharged after the water turbine is operated, the discharge valve 124

Opened and discharged by the vacuum pump 127 The evacuated pipe is discharged to a nearby sea depth (-10m) through a discharge tunnel without resistance.

Therefore, the emission under the tidal difference is the basic design for all marine discharged water to reduce wind resistance and marine pollution of the atmosphere.
