Description

해양 부유 구조물 및 이를 이용한 해상 부유식 풍력 발전장치{Floating offshore structure and Floating offshore wind turbine using the same}Floating offshore structure and Floating offshore wind turbine using the same}

본 발명은 해양 부유 구조물 및 이를 이용한 풍력 발전장치에 관한 것으로, 보다 구체적으로 설명하면, 해상에서 바람을 이용하여 전기를 생산하는 풍력 발전기에 사용되는 해양 부유 구조물 및 이를 이용한 해상 부유식 풍력 발전장치에 관한 것이다.
The present invention relates to an offshore floating structure and a wind turbine using the same, and more specifically, to an offshore floating structure used for a wind generator for producing electricity using wind in the sea and an offshore floating wind turbine using the same It is about.

일반적으로, 해양 풍력발전은 고정식과 부유식으로 나눌 수 있으며, 고정식은 수심이 깊지 않은 바다의 해저면에 기초공사를 하고, 그 기초공사 위에 구조물을 설치한 후 발전설비를 설치하는 방식이고, 부유식은 해수면 위에 부유 구조물을 띄우고 그 부유 구조물 위에 발전설비를 설치하는 방식이다.In general, offshore wind power generation can be divided into fixed and floating type, and fixed type is a method of installing foundations on the sea floor of the sea without deep water, and installing power generation facilities after installing the structure on the foundation. The equation is to float the floating structure on the sea level and to install the power generation facilities on the floating structure.

해양 부유 구조물은 해수면 위에 떠 있는 상태로 계류될 수 있는 것으로, 기능, 구조, 계류 방식 등에 따라 다양한 종류로 분류된다.Marine floating structures can be moored on the sea surface and are classified into various types according to their function, structure, and mooring method.

예를 들면, SEMI(Semi-submersible), TLP(Tensioned Leg Platform), SPAR, FPSO(Floating, Production, Storage and Off-loding), FSRU 또는 시추용 리그(Rig) 등으로 칭해지는 많은 종류의 해양 부유 구조물이 있다.For example, many types of oceanic suspensions called semi-submersible (TEM), tensioned leg platform (TLP), SPAR, floating, production, storage and off-loding (FPSO), FSRU, or drilling rigs. There is a structure.

이와 같은, 해양 부유 구조물은 그 종류에 따라 한 방식의 계류 시스템을 이용한다. 예컨대, SPAR 타입의 해양 부유 구조물은 터트 계류(taut mooring) 또는 세미-터트 계류(semi-taut mooring)방식을 취하며, TLP 타입의 해양 부유 구조물은 인장각(tensioned leg)들을 이용하는 TLP 계류 방식을 취한다.Such marine floating structures use one type of mooring system, depending on their type. For example, SPAR-type offshore floating structures take a taut mooring or semi-taut mooring method, while TLP-type offshore floating structures employ a TLP mooring method using tensioned legs. Take it.

TLP 계류 방식은 부력을 갖는 해양 부유 구조물을 해양에 계류시킴에 있어서, '텐덤'으로 칭해지는 수직의 계류 줄들에 강한 인장력을 부여하여 이루어지는 것으로, 통상 터트 계류(taut mooring) 또는 세미-터트 계류(semi-taut mooring)에 비해 거친 해양 조건에서도 해양 부유 구조물을 안정적으로 유지시켜줄 수 있다.The TLP mooring method is a method of mooring a buoyant offshore floating structure to the ocean, by applying a strong tensile force to vertical mooring strings called 'tandems'. Compared to semi-taut mooring, marine floating structures can be stably maintained even in rough marine conditions.

그러나, TLP 계류 방식은 텐덤에 가해지는 큰 장력으로 인하여 피로에 의한 파손의 위험이 존재하는 단점이 있다.However, the TLP mooring system has a disadvantage that there is a risk of damage due to fatigue due to the large tension applied to the tandem.

또한, 해양 환경 또는 조건에 상관없이 텐덤에 항상 강한 장력이 가해져야 하고 이로 인해 수명 연장에 어려움이 있으므로, 기존 해양 부유 구조물에 비해 장기간 한 위치에 계류되어야 하는 풍력 발전 용도에는 잘 부합되지 않는 문제점 있다.
In addition, regardless of the marine environment or conditions, the tandem must always have a strong tension, which is difficult to prolong the life of the tandem, there is a problem that is not well suited for wind power applications that need to be moored in one position compared to the existing offshore floating structures .

본 발명은 상술한 바와 같은 문제를 해결하기 위해 안출된 것으로, 해양 환경 또는 조건에 따라 계류수단의 장력을 능동적으로 조절할 수 있도록 하여 장력에 의한 피로에 의한 파손을 감소시킬 수 있는 해양 부유 구조물 및 이를 이용한 해상 부유식 풍력 발전장치를 제공하는 것을 목적으로 한다.

Therefore, definitions of these terms should be made based on the contents throughout this specification.

도 1 내지 도 3를 참조하면, 본 발명의 일실시예에 따른 해양 부유 구조물 (100)은 부유체(110), 계류수단(120)을 포함하여 이루어진다.1 to 3, the marine floating structure 100 according to an embodiment of the present invention includes a floating body 110 and a mooring means 120.

이와 같은, 해양 부유 구조물(100) 상에는 풍력 발전장치(130)가 마련되며, 풍력 발전장치(130)는 부유체(110)의 상부에 설치되는 타워(132)와, 타워(132)의 상부에 설치되어 후술하는 블레이드(136)의 회전력으로부터 전기를 발생시키는 낫셀(134)과, 낫셀(134)에 회전 가능하게 설치되어 풍력에 의해 회전하는 블레이드(136)를 포함하여 이루어진다. As such, the wind turbine 130 is provided on the marine floating structure 100, the wind turbine 130 is a tower 132 is installed on top of the floating body 110, and the top of the tower 132 It includes a natsel 134 installed to generate electricity from the rotational force of the blade 136, which will be described later, and a blade 136 rotatably installed in the natsel 134 and rotated by wind power.

부유체(110)는 해양에 부유 가능하도록 형성되며, 부력을 갖는 구조물로 이루어진다.Floating body 110 is formed to be floating in the ocean, made of a structure having buoyancy.

이러한, 부유체(110)는 정원뿔형상, 역원뿔형상, 정다각뿔형상, 역다각뿔형상 중에서 적어도 어느 하나의 형상으로 이루어진다.The floating body 110 has at least one of a cone shape, an inverted cone shape, a regular polygonal cone shape, and an inverted polygonal cone shape.

여기서, 부유체(110)가 정원뿔형상 또는 정다각뿔형상으로 이루어졌을 경우에는 부유체(110)가 파도의 영향을 작게 받아 부유체(110)가 수심에 상관없이 효과적이 부력을 가질 수 있으나, 파도의 파고가 높을 경우에는 부유체(110)의 하부가 해저면에 닿는 문제가 발생되므로 역원뿔형상 또는 역다각뿔형상으로 이루어지는 것이 바람직하다.Here, when the floating body 110 is formed in the shape of a garden cone or a regular polygonal pyramid, the floating body 110 may be effectively buoyant regardless of the depth of the floating body 110 under the influence of the wave, When the wave height is high, since the lower part of the floating body 110 comes into contact with the sea bottom, it is preferable that the inverted cone shape or the inverted polygonal shape is formed.

또한, 부유체(110)가 역원뿔형상 또는 역다각뿔형상으로 이루어졌을 경우에는 부유체(110)의 무게중심을 낮추기 위해 부유체(110)의 저부에 무게추(112)가 결합된다.In addition, when the floating body 110 is formed of an inverted cone shape or an inverted polygonal shape, the weight 112 is coupled to the bottom of the floating body 110 to lower the center of gravity of the floating body 110.

아울러, 부유체(110)의 외주면에는 복수개의 날개부(114)가 부유체(110)의 둘레 방향을 따라 일정 간격 이격하여 형성되는데, 이 날개부(114)는 부유체(110)의 파도의 주기에 따른 진폭응답함수(RAO: Response Ampiltude Operator)를 저감시켜 부유체(110)가 해양에 안정적으로 부유되도록 한다.In addition, a plurality of wings 114 are formed on the outer circumferential surface of the floating body 110 at regular intervals along the circumferential direction of the floating body 110, and the wing portions 114 are formed of waves of the floating body 110. Reducing the amplitude response function (RAO: Response Ampiltude Operator) according to the cycle to ensure that the floating body 110 is stably suspended in the ocean.

이때, 파도의 주기에 따른 진폭응답함수(RAO)는 전후동요(Surge), 상하동요(Heave), 종동요(Pitch), 선수동요(Yaw)가 된다.At this time, the amplitude response function (RAO) according to the period of the wave is a surge, up and down (Heave), bell (Pitch), bow (Yaw).

이러한, 날개부(114)는 도 3에 도시된 바와 같이, 부유체(110)의 높이 방향을 따라 일부분만 형성되거나, 부유체(110)와 동일한 높이로 형성될 수 있으며, 삼각형 또는 사각형으로 이루어질 수 있다.This, wing portion 114, as shown in Figure 3, may be formed only a portion along the height direction of the float 110, or may be formed at the same height as the float 110, made of a triangle or quadrangle Can be.

계류수단(120)은 부유체(110)가 해양에 계류하도록 부유체(110)의 저면에 일단이 결합되는 와이어(122)와, 와이어(122)의 타단에 결합되어 해저면에 지지되는 앵커(124)로 구성된다. The mooring means 120 is a wire 122, one end of which is coupled to the bottom of the float 110, and the other end of the wire 122 is anchored to the sea bottom so that the float 110 is mooring to the ocean ( 124).

이때, 와이어(122)의 길이 방향 소정 위치에는 탄성부(122a)가 형성되는데, 이 탄성부(122a)는 부유체(110)가 회전되는 것을 방지하고, 부유체(110)가 파도의 주기에 따라 운동할 때 발생되는 충격을 완화시키는 역할을 한다.At this time, the elastic portion 122a is formed at a predetermined position in the longitudinal direction of the wire 122, and the elastic portion 122a prevents the floating body 110 from rotating, and the floating body 110 is formed in a cycle of waves. It plays a role in mitigating the shock that occurs when exercising.
