본 발명은 해상용 풍력발전기 설치방법에 관한 것으로, 더욱 상세하게는 높은 위치에 설치되는 상부지주를 유도레일과 천정크레인으로 신속 정확 및 안전하게 중간지주 상단에 설치하기 위한 방법으로서, 하부지주 양측에 고정시킨 바지(Barge)선을 연접시켜 작업장을 만들어 작업의 안정성을 높이고, 갑판과 중간 지주 상에 유도레일을 설치하여 천정크레인에 의해 상부지주를 신속 정확하게 중간지주 상단에 설치할 수 있는 유도레일을 이용한 해상용 풍력발전기 설치방법에 관한 것이다.The present invention relates to a method for installing an offshore wind turbine, and more particularly, a method for quickly and accurately installing an upper column installed at a high position on an upper end of an intermediate column with an induction rail and a ceiling crane, and fixed to both sides of the lower column. The barge line is connected to make the workshop, which improves the stability of the work, and the guide rail is installed on the deck and the middle support, so that the upper rail can be quickly and accurately installed on the upper part of the middle land by the overhead crane. It relates to a wind turbine generator method.

현실적으로 지속적인 화석연료의 비용증가와 화석연료에서 발생되는 해로운 가스로 인한 환경파괴 및 핵발전 에너지와 관련된 잠재적인 위험으로 인해, 풍력발전은 자연상태의 무공해 에너지원으로 현재의 기술에 의한 대체에너지원 중 가장 경제성이 높은 에너지원으로써 풍력발전은 바람의 힘을 회전력으로 전환시켜 발생되는 전력을 전력계통이나 수요자에 직접 공급하는 기술이다. 이러한 풍력발전을 이용한다면 산간이나 해안오지 및 방조제 등 부지를 활용함으로써 국토이용효율을 높일 수 있다. In reality, wind power is a natural, non-polluting energy source, due to the ongoing costs of fossil fuels and the potential risks associated with environmental destruction and nuclear energy from harmful gases from fossil fuels. As the most economical energy source, wind power is a technology that directly supplies power generated by converting wind power to rotational power to a power system or a consumer. If such wind power is used, the land use efficiency can be improved by utilizing the sites such as mountains, coastal backcountry, and embankments.

이러한 장점 때문에, 풍력발전 시스템은 가장 유력한 대체 에너지원으로 인정을 받고 있으며 이미 전 세계적으로 약 32,154MW(2002년말 누계기준)의 풍력발전 시스템이 설치 사용되고 있다. 이중, '02년 한해 동안 설치된 풍력발전 시스템의 용량은 7,227MW 이며, 이는 그해 건설된 원자력발전소 용량보다도 큰 수치이다. Because of these advantages, wind power systems are recognized as the most viable alternative energy sources and wind power systems of around 32,154 MW (total 2002) are already being installed and used worldwide. Among them, the capacity of wind power generation system installed in 2012 is 7,227MW, which is larger than the capacity of nuclear power plants built that year.

우리나라도 세계기후변화협약과 같은 국제 환경의 변화와 유가상승, 그리고 국내사용 에너지의 96%를 수입에 의존하고 있는 현실적인 문제에 대응하기 위하여 풍력발전 시스템에 대한 관심이 높다. Korea also has a strong interest in wind power generation systems in order to cope with changes in the international environment such as the World Climate Change Convention, rising oil prices, and realistic problems that depend on imports for 96% of domestic energy use.

뿐만 아니라, 풍력발전 시스템은 구조나 설치 등이 간단하여 운영 및 관리가 용이하고 무인화 및 자동화 운전이 가능하기 때문에 최근에 도입이 비약적으로 증 가하고 있다.In addition, the introduction of wind power generation systems has recently increased dramatically because the structure and installation are simple, easy to operate and manage, and unmanned and automated operation.

그러나, 이러한 장점에 비하여 종래의 해상용 풍력 발전기를 설치하기 위한 방법은 파도 등 해상 작업의 곤란성으로 인하여 핀랜드의 '린타-죠피.어조'가 출원번호 제10-2002-7005923호(2002.05.08)로 국내에 출원한 "해상에 연안 풍력발전기를 설치 및 운반하는 방법 및 시스템"이 있으나, 이는 육지에서 풍력 발전기를 제작하여 크레인선으로 운반하여 설치하는 것이어서 풍력발전기의 무게와 크기에 한계가 있고, 해상에 견고히 고정되지 못하여 안전성에도 커다란 문제점이 있고, 아일랜드의 '하네빅 크리스토퍼' 등이 출원번호 제10-2003-7001174호(2003.01.27)로 국내에 출원한 "풍력터빈을 해양에 설치하기 위한 부유구조물"이 있으나, 이는 구조물이 부유되어 연결선으로 풍력터빈이 설치된 부유구조물을 지지하는 것이어서, 연결선의 안정적이 설치가 곤란하고, 파도에 의한 구조물의 운동으로 안전성이 매우 낮다는 문제점이 있다.However, compared to these advantages, the conventional method for installing an offshore wind power generator is due to the difficulty of offshore operations such as waves, Finland's 'Linta-Joffee's tone' No. 10-2002-7005923 (2002.05.08) There is a "filed method and system for installing and transporting offshore wind turbines on the sea" filed in Korea, but this is to manufacture a wind generator on land and transport it to a crane ship for installation and there is a limit to the weight and size of the wind turbine. There is a big problem in safety because it is not firmly fixed at sea, and 'Hanevik Christopher' of Ireland, etc. filed in Korea under the application number 10-2003-7001174 (January 27, 2003) "Floating structure", but this is because the structure is floating to support the floating structure with a wind turbine installed as a connection line, it is difficult to install a stable connection line, There is very low is the problem of safety in movement of the structure according to Fig.

상술한 바와 같은 문제를 해결하기 위하여 본 발명에서는, 해상에 안정된 작업장을 만들어 유도레일과 타워크레인에 의해 해상용 풍력발전기의 상부지주를 설치함으로서 종래의 설치방법에 비해 설치비용이 절감되고 더 효율적으로 설치할 수 있는 유도레일을 이용한 해상용 풍력발전기 설치방법을 제공하는 것을 목적으로 한다.In order to solve the problems as described above, in the present invention, by creating a stable work site on the sea by installing the upper column of the offshore wind turbine by the guide rail and the tower crane, the installation cost is reduced and more efficiently than the conventional installation method An object of the present invention is to provide a marine wind turbine installation method using an induction rail that can be installed.

상기와 같은 목적을 달성하기 위한 본 발명의 해상용 풍력발전기용 타워크레인 설치방법은 먼저 대형 하부지주를 해상에 설치하고, 특수형상 바지(Barge)선에 구비된 고정포스트를 이용하여 하부지주 양측에 밀착하면서 상기 바지선을 고정시켜 작업장을 만들고, 상기 하부지주 상부 양측에 타워크레인을 설치하여 너셀부와 천정크레인을 상승시킨 뒤, 중간지주를 설치하고, 갑판과 중간지주 전면에 유도레일을 설치하여 상부지주가 상기 천정크레인에 의해 유도레일을 따라 인양되게하여 설치하는 것이다. 그리고, 프로펠러는 너셀 받침대, 지지틀, 유도레일 및 타워크레인 등의 장치들을 해체시킨 뒤, 갑판상의 윈치로 너셀 회전부 내부의 롤러와 연결된 프로펠러를 인양하여 상기 회전부의 결합홈에 삽입시켜 프로펠러를 설치하고, 상기 바지선을 분리하여 동력선으로 이동시키는 유도레일을 이용한 해상용 풍력발전기의 설치를 위한 방법에 관한 것이다.In order to achieve the above object, the tower crane installation method for a marine wind turbine of the present invention first installs a large lower column on the sea, and uses a fixed post provided on a barge line on both sides of the lower column. While making close contact with the barge, the workshop is made, and tower cranes are installed on both sides of the upper part of the lower column to raise the nussel part and the ceiling crane, and then, the intermediate column is installed, and the guide rail is installed on the front of the deck and the intermediate column. The pillar is installed by being lifted along the guide rail by the ceiling crane. Then, the propeller dismantles the device such as the nussel base, the support frame, the guide rail and the tower crane, and lifts the propeller connected to the roller inside the reel part with the winch on the deck and installs the propeller by inserting it into the coupling groove of the rotating part. The present invention relates to a method for installing an offshore wind power generator using an induction rail for separating a barge and moving a power line.
