Description

해상 풍력발전기의 위치 제어 및 부가 발전 장치{positioning control system and generating system at wind power in sea}Positioning control system and generating system at wind power in sea

본 발명은 해상풍력발전의 위치제어를 하기위한 기술로서 해수의 고압분사에 따른 추진력을 이용하여 풍력발전기를 자세를 제어하는 기술이다.The present invention is a technique for controlling the position of the wind power generator using the propulsion force according to the high pressure injection of seawater as a technique for position control of offshore wind power generation.

동시에 저장되는 해수를 이용하여 발전을 하는 기술이다. It is a technology that generates power using seawater stored at the same time.

해수를 펌핑하여 고압으로 저장한 후 이를 분사하여 의 분사시의 추진력을 이용하여 해상에서의 구조물의 중심을 제어하며 동시에 분사 시 발생하는 에너지로 동시 발전을 하는 기술이다.It is a technology that pumps seawater, stores it at high pressure, and then injects it to control the center of the structure at sea using the propulsion force at the time of injection.

현재 풍력발전기가 고안되어 지상에 설치되어있고 또한 해상의 풍력에너지를 이용하여 해상에 풍력발전기를 설치하고 있으나 저심도의 해상 풍력발전기는 콘크리트를 타설하여 고정시킬 수 있으나 일정한 깊이를 초과할 경우 콘크리트 구조물의 형태로 고정이 불가능하여 닻의 형태로 발전기를 고정시키고 있다.Currently, wind power generators are designed and installed on the ground, and wind turbines are installed on the sea by using offshore wind energy. However, offshore wind turbines with low depth can be fixed by pouring concrete. It is impossible to fix in the form of the anchor is fixing the generator in the form of an anchor.

그러나 닻의 경우 일정 위치는 고정이 되나 풍력발전기의 자세가 파도나 바람이 심하게 불 경우 기울어지는 단점이 있어 이를 해결하는 것이 본 발명이 해결하고자하는 과제이다.However, in the case of the anchor fixed position is fixed but the disadvantage of the wind turbine generator posture tilted when the wave or the wind blows badly to solve this problem is an object of the present invention to solve.

본 발명은 타워주변에 다수의 펌프를 설치하여 파도가 칠 때 파도의 힘을 이용하여 펌핑을 하여 풍력발전기 타워 아래 부분에 고압으로 저장하여둔 후 이를 일정량 이상의 바람을 풍력발전기가 받을 경우 그 풍력에 비례하여 풍향 방향으로 풍력발전기의블레이드 반대방향으로 해수를 분사하게 하여 추진력으로 발전기의 자세를 잡아주는 동시에 발전도 하는 것이다.According to the present invention, a plurality of pumps are installed around the tower to pump using the force of the waves when the waves hit and store them at a high pressure in the lower part of the wind turbine tower, and then receive a certain amount of wind when the wind generator receives the wind. In proportion to the wind direction, the seawater is sprayed in the opposite direction to the blades of the wind turbine, and the generator is positioned at the same time as the propulsion force.

해상풍력발전기의 자세를 제어하여줄 수 있음으로 해서 고심도 해양에 다수의 해상풍력발전단지의 설치가 가능해지므로 무한한 해상풍력 에너지의 활용이 가능하여지므로 청정에너지 확보를 통한 에너지의 위기를 넘어 이산화탄소 배출 감소 효과와 더불어 기후 온난화 방지에도 크게 기여할 것이다By controlling the attitude of offshore wind power generators, it is possible to install a large number of offshore wind power complexes in high-depth oceans, enabling unlimited offshore wind energy use. Along with the reduction effect, it will greatly contribute to preventing climate warming.

본 발명은 해수의 분사를 통해 발생하는 추진력을 이용한 위치제어시스템으로 먼저 풍력발전기의 타워 하부 내측에 고압 해수조(101)를 설치하고 해수조위에 해수 펌프(105)를 설치하여 해수를 고압으로 저장하게 한다. 이때 해수저장용으로 단순히 펌프를 사용하여 저장할 수 있으며, 또한 그 타워 외부를 둘러싸고 플레이트형태의 직선형펌프(202)나 나선형펌프(403)를 설치를 하여 파력이나 조력을 이용하는 방법을 이용하여 파도가 칠 때의 해수를 그 해수조안에 저장토록 한다.The present invention is a position control system using the propulsion force generated through the injection of sea water first to install a high pressure seawater tank 101 inside the tower bottom of the wind power generator and install a seawater pump 105 on the seawater tank to store the seawater at high pressure Let's do it. At this time, it can be stored simply by using a pump for sea water storage, and waves are formed by using wave or tidal force by installing a linear pump 202 or spiral pump 403 in the form of a plate surrounding the outside of the tower. Allow seawater to be stored in the seawater tank.

파력을 이용할 경우 펌프는 직선형태의 펌프나 나선형 펌프를 이용할 수 있다.In the case of wave power, the pump may be a straight pump or a helical pump.

직선형펌프의 경우는 파도가 풍력발전기의 해저부분에 미치는 파력을 완화시키는 완충기의 역할을 하기도 한다.In the case of straight pumps, it acts as a shock absorber to mitigate the wave force on the seabed of the wind turbine.

나선형펌프의 경우는 별도로 펌프를 회전시키는 외부 수차를 설치하고 수차의 배치는 편향에 의한 발전기의 쏠림을 방지하기 위해 교차하여 양방향으로 운동하게 설치한다. 쌍방교차로 설치한 수차는 운동제어로 전체적인 해상풍력발전기의 의 방향 제어도 가능하다.  In the case of the helical pump, an external aberration is installed to rotate the pump separately, and the arrangement of the aberration is installed so as to cross and move in both directions to prevent the generator from being deflected by deflection. The aberrations installed in two-way crossovers can control the direction of the offshore wind power generator by the motion control.

해상풍력발전기가 일정량 이상의 풍력을 받을 때 그 풍향을 감지하고 방향이 전환되는 블레이드의 방향에 따라 노즐조절기를 통하여 풍속과 풍향에 따라 해수를 분사하게 한다. 분사용 노즐의 경우 원형의 타워외부에 노즐을 돌출시키고 원형으로 다수의 노즐을 균등하게 배치하여 어느 방향으로든 분사가 가능하게 한다.When the offshore wind turbine receives more than a certain amount of wind, the wind direction is sensed and the seawater is sprayed according to the wind speed and the wind direction through the nozzle controller according to the direction of the blade to be redirected. In the case of injection nozzles, the nozzles protrude outside the circular tower and a plurality of nozzles are evenly arranged in a circular shape to enable injection in any direction.

하부 노즐의 경우 파도가 받는 힘을 상쇄시키도록 노즐을 분사시키고 상부 노즐의 경우는 풍속에 따라 발전기가 받는 힘을 상쇄시키도록 작동시킨다.In the case of the lower nozzle, the nozzle is sprayed to cancel the force applied by the wave, and in the case of the upper nozzle, the generator is operated to offset the force of the generator according to the wind speed.

동시에 고압 해수의 압력이 일정 압력이하로 떨어질 경우 콤프레셔(106)를 가동시켜 항시 분사가 가능 하게한다. At the same time, when the pressure of the high-pressure seawater drops below a certain pressure, the compressor 106 is operated to enable injection at all times.

또한 파력에 의한 해수저장이 일정압력을 넘어서면 이를 자동으로 감지하여 노즐을 통해 발전을 하게 하며 이때 노즐분사는 일정방향으로 힘이 쏠리지 않도록 대칭이 되게 양방 또는 사방으로 분사하여 발전한다. In addition, when seawater storage by wave force exceeds a certain pressure, it automatically detects it and generates power through the nozzle. At this time, the nozzle injection is generated by spraying in both directions or in all directions so as to be symmetrical so as not to force force in a certain direction.
