부유식 해상풍력발전장치 모형시험용 실해역 바람 구현장치{Real­sea wind realization device for floating offshore wind turbine model test}Real sea wind realization device for floating offshore wind turbine model test

본 발명은, 수조 축소모형시험시 부유식 해상풍력발전장치에 풍압을 모사하여 구현되게 하는 부유식 해상풍력발전장치 모형시험용 실해역 바람 구현장치에 관한 것이다.The present invention relates to an actual sea area wind realization device for a model test of a floating offshore wind power plant, which simulates wind pressure in a floating offshore wind power generator during a water tank scale model test.

일반적으로, 부유식 구조물과 밀접하게 연관된 해양공학 분야에서는 해양공학수조에서 축소모형시험 시, 축소법칙(Froude scaling)을 사용한다.In general, in the field of marine engineering closely related to floating structures, Froude scaling is used when testing a scale model in an ocean engineering tank.

특히, 부유식 해상풍력발전장치의 경우, 축소법칙을 날개의 형상과 풍속, 로터의 분당회전수(RPM)에 적용하게 되는데, 축소모형이 받는 공력이 실스케일의 부유식 해상풍력발전장치가 받는 공력에 한참 미치지 못하는 문제가 발생한다.In particular, in the case of a floating offshore wind power generator, the reduction rule is applied to the shape and wind speed of the wing, and to the revolutions per minute (RPM) of the rotor. There is a problem that does not reach the aerodynamics for a long time.

따라서, 축소모형시험 시, 공력을 최대한 고려하기 위해서는 부유식 해상풍력발전장치의 운동에 크게 영향을 주는 추진력(Thrust force)를 맞추는 것이 일반적인 방법으로 사용된다.Therefore, in the scale model test, in order to consider aerodynamics as much as possible, the general method is to match the thrust force, which greatly affects the motion of the floating offshore wind power generator.

그러나, 종래의 해양공학수조는 파도, 바람, 조류를 복합적으로 생성할 수 있지만 해양공학수조의 바람발생장치를 이용하여 풍력발전장치에 작용하는 추진력을 생성하거나 날개에 변동풍을 구현하는 것은 불가능에 가깝다. 이에 따라, 해양공학수조에서 해상에 설치될 풍력발전장치의 모형 시험이 실시될 경우, 풍력발전장치의 거동특성과 추진력에 의해 작용하는 하중을 정확히 파악하기 어려운 문제점이 있다.However, the conventional marine engineering tank can generate waves, wind, and currents in a complex way, but it is impossible to use the wind generator of the ocean engineering tank to generate the driving force acting on the wind power generator or to implement the fluctuating wind on the wing. close. Accordingly, when a model test of a wind power generator to be installed in the sea is carried out in the marine engineering tank, there is a problem in that it is difficult to accurately grasp the behavioral characteristics of the wind power generator and the load applied by the propulsion force.

이러한, 풍력발전장치용 시험장치에 대한 관련기술은, 대한민국등록특허 제10-1207416호(2012.11.27)에 제시된다.The related technology for such a test apparatus for a wind power generator is presented in Korean Patent Registration No. 10-1207416 (November 27, 2012).

상기 장력조절모터(200)는 풍압모사 와이어(100)를 감김 또는 풀림되게 하면서 풍압모사 와이어(100)의 장력을 조절되게 하는 모터이다. 즉, 장력조절모터(200)는 풍압모사 와이어(100)를 감김 또는 풀림되게 하면서 축소모형(10)의 너셀(11)에 가해지는 당김힘을 조절하면서 로터 허브(12)에 형성된 날개(13)에 걸리는 풍압으로 모사되게 구현할 수 있게 한다.The tension control motor 200 is a motor that adjusts the tension of the wind pressure simulation wire 100 while winding or unwinding the wind pressure simulation wire 100 . That is, the tension control motor 200 winds or unwinds the wind pressure simulating wire 100 and adjusts the pulling force applied to the nacelle 11 of the reduced model 10 while controlling the wing 13 formed on the rotor hub 12. It can be simulated by the wind pressure applied to it.

More preferably, the connection guide roller 220 is connected to the rear end portion of the nacelle 11 in a state in which one end in the longitudinal direction of the wind pressure simulating wire 100 is extended and disposed on the same axis as the rotation axis of the nacelle 11 . Thus, the force applied to the nacelle 11 through the change in the tension of the wind pressure simulating wire 100 can be accurately realized and transmitted as the wind pressure applied to the wing 13 formed in the rotor hub 12 .

더불어, 상기 축소모형(100)과 연결 가이드롤러(220) 사이 및, 장력조절모터(200)와 연결 가이드롤러(220) 사이에는 장력유지롤러(도면미도시)를 구비할 수도 있다. 이러한, 장력유지롤러는 풍압모사 와이어(100)를 일정한 장력 이상으로 유지되게 하면서 이동이 이루어지게 가이드하는 바, 풍압모사 와이어(100)가 감김 또는 풀림시 장력의 변화를 통한 축소모형(100)으로 힘의 전달이 안정적으로 이루어지게 할 수 있다.In addition, a tension maintaining roller (not shown) may be provided between the reduced model 100 and the connection guide roller 220 and between the tension control motor 200 and the connection guide roller 220 . Such a tension maintaining roller guides the movement while maintaining the wind pressure simulating wire 100 at a certain tension or more, and as the wind pressure simulating wire 100 is wound or unwound, a reduced model 100 through a change in tension. The transmission of force can be made stably.

상기 장력 제어부(300)는 풍압모사 와이어(100)의 장력을 측정한 후, 장력조절모터(200)의 구동축 회전방향을 조절하여 장력조절롤러(210)에 풍압모사 와이어가 감김 또는 풀림되는 정도를 조절하면서 축소모형(10)에 가해지는 풍압을 구현되게 하는 부분이다. 이러한, 장력 제어부(300)는 풍압모사 와이어(100) 및 장력조절모터(200)와 연결되게 설치한다. 여기서, 장력 제어부(300)는 로드셀(310), 모터제어수단(320)을 포함한다.The tension control unit 300 measures the tension of the wind pressure simulating wire 100, and then adjusts the rotation direction of the drive shaft of the tension control motor 200 to determine the extent to which the wind pressure simulating wire is wound or unwound in the tension control roller 210. It is a part that realizes the wind pressure applied to the reduced model 10 while adjusting. The tension control unit 300 is installed to be connected to the wind pressure simulating wire 100 and the tension control motor 200 . Here, the tension control unit 300 includes a load cell 310 and a motor control means 320 .

상기 로드셀(310)은 풍압모사 와이어(100)의 장력을 측정하는 수단이다. 이러한, 로드셀(310)은 풍압모사 와이어(100)의 장력을 측정할 수 있도록 풍압모사 와이어(100)에 연결 배치되도록 설치한다. 보다 상세하게는 로드셀(310)은 장력조절모터(200)의 장력조절롤러(210)의 외주면에 결합 설치하는 것이 바람직하나, 이에 한정하지 않고 연결 가이드롤러(220) 및 장력유지롤러에 적어도 하나를 결합 구비하여 풍압모사 와이어(100)의 이동시 장력을 정확하게 측정할 수 있게 한다. 이렇게, 로드셀(310)은 모터제어수단(320)과 케이블과 같은 유선 또는 와이파이, 블루투스, 적외선통신과 같은 무선수단을 통해 연결되어, 측정된 풍압모사 와이어(100)의 장력 수치를 모터제어수단(320)으로 전달한다.The load cell 310 is a means for measuring the tension of the wind pressure simulation wire (100). Such a load cell 310 is installed so as to be connected to the wind pressure simulation wire 100 so as to measure the tension of the wind pressure simulation wire 100 . In more detail, the load cell 310 is preferably coupled to the outer circumferential surface of the tension control roller 210 of the tension control motor 200, but is not limited thereto. By having a coupling, it is possible to accurately measure the tension when the wind pressure simulation wire 100 moves. In this way, the load cell 310 is connected to the motor control means 320 and a wire such as a cable or wireless means such as Wi-Fi, Bluetooth, and infrared communication, and the measured tension value of the wind pressure simulating wire 100 is measured by the motor control means ( 320).
