Description

풍력 발전기용 요 드라이브 및 피치 드라이브의 테스트장치Testing device for yaw drive and pitch drive for wind generator
본 발명은 풍력 발전기용 요 드라이브 및 피치 드라이브의 테스트장치에 관한 것으로, 더욱 상세하게는 성능 테스트를 하고자 하는 요 드라이브 또는 피치 드라이브의 출력부의 회전운동을 직선운동으로 변환하는 래크를 설치하여 상기 래크에 부하를 주는 유압실린더를 연계하여 그 구조가 간단하고 소음 발생이 작으며 작업장 내에서 차지하는 공간을 최소화시킬 수 있는 풍력 발전기용 요 드라이브 및 피치 드라이브의 테스트장치에 관한 것이다.The present invention relates to a test apparatus for a wind drive yaw drive and a pitch drive, and more particularly, to the rack by installing a rack for converting the rotational movement of the output of the yaw drive or pitch drive to a linear motion to be tested for performance. The present invention relates to a test apparatus for a yaw drive and a pitch drive for a wind power generator, which is simple in structure, low in noise, and minimizes space in a workplace by connecting a load hydraulic cylinder.
일반적으로 풍력 발전기는 바람의 에너지를 전기에너지로 바꿔주는 장치로서, 풍력 발전기의 날개를 회전시켜 이때 생긴 날개의 회전력으로 전기를 생산한다. 풍력 발전기는 바람이 지니고 있는 에너지를 전기에너지로 바꿔주는 장치이다. 즉. 바람이 풍력 발전기의 블레이드를 회전시키게 되며 이때 생긴 블레이드의 회전력으로 전기를 생산할 수 있다.In general, the wind generator is a device that converts the energy of the wind into electrical energy, and rotates the blades of the wind generator to produce electricity by the rotational force of the blades generated at this time. Wind generators are devices that convert wind energy into electrical energy. In other words. The wind rotates the blades of the wind generator, and the blades can produce electricity.
이러한, 풍력 발전기에 사용되는 바람 운동 에너지는 석유, 석탄 등의 화석 연료를 이용한 에너지와 비교하여 공해 물질의 배출이 없고, 매장량이 제한되어 있는 화석 연료를 사용하지 않음에 따라 자원의 고갈될 염려가 없으며, 방사능의 유출 가능성이 높은 원자력 에너지와 비교하여 자연 에너지를 이용함에 따라 안정성이 높아 친환경 에너지로 각광받고 있다.The wind kinetic energy used in the wind generators, compared with the energy using fossil fuels such as petroleum and coal, has no emission of pollutants, and there is a risk of depletion of resources due to not using fossil fuels with limited reserves. In addition, the use of natural energy as compared to nuclear energy, which has a high possibility of leakage of radioactivity, has been spotlighted as environmentally friendly energy due to its high stability.
상기와 같은 바람을 이용하는 풍력 발전기는 크게 지면에 고정되는 타워와 상기 타워의 상단에 설치되어 발전기 등이 설치되는 너셀(NACELLE)과 상기 너셀의 발전기와 축으로 연결되어 바람에 의해 회전하는 블레이드로 구성된다.The wind generator using the wind as described above is composed of a tower fixed to the ground and the top of the tower is installed in the top of the tower (NACELLE) and the generator is installed in the blade and the blade rotated by the wind connected to the shaft of the generator of the nussel do.
특히, 상기와 같은 풍력 발전기는 바람이 불어오는 방향에 맞추어 너셀이 회전하도록 함으로써 발전효율을 높일 수 있게 타워와 너셀에는 요 드라이브(YAW DRIVE)가 설치되며 상기 너셀에는 블레이드 각각의 각도를 조절하는 피치 드라이브(PITCH DRIVE)가 설치된다.In particular, in the wind generator as described above, the yaw DRIVE is installed in the tower and the nussel so as to increase the power generation efficiency by allowing the nussel to rotate in the direction of the wind blowing, and the pitch of the angle of each blade is adjusted in the nussel. PITCH DRIVE is installed.
특히, 상기 요 드라이브 및 피치 드라이브는 크게 전기 에너지를 회전운동으로 변환하는 구동모터 또는 서보모터와 같은 입력부와 상기 입력부에서 제공되는 회전력을 적정 회전수로 변환시키기 위한 감속부 및 상기 감속부를 거친 회전력에 의해 너셀 또는 블레이드를 회전시키는 출력부로 구성된다.Particularly, the yaw drive and the pitch drive are provided with an input unit such as a drive motor or a servo motor which largely converts electric energy into a rotational motion, and a deceleration unit for converting the rotational force provided from the input unit to an appropriate rotational speed and the rotational force through the reduction unit. It consists of an output unit for rotating the nussel or blade.
이와 같은 구성을 갖는 풍력 발전기에 설치되는 요 드라이브 및 피치 드라이브는 풍력 발전기의 설치 환경에 따라 바람의 방향과 세기에 차이가 있기 때문에 내구성이 강한 것을 사용해야 사용도중에 교체 및 수리를 줄일 수 있다.Yaw drive and pitch drive installed in the wind power generator having such a configuration can be reduced in replacement and repair during use, because the use of a durable one because there is a difference in the direction and strength of the wind depending on the installation environment of the wind generator.
따라서, 요 드라이브 및 피치 드라이브가 풍력 발전기에 탑재되기 전에 요 드라이브 및 피치 드라이브의 성능을 시험하기 위한 테스트 과정이 필요하게 된다. 이를 위해, 종래에는 요 드라이브 및 피치 드라이브를 지속적으로 부하를 발생시켜 요 드라이브 내지 피치 드라이브의 정회전 및 역회전 사이클 시험, 정격 토크의 120%를 수용한 가속수명시험, 구동 토크 모니터링 및 기록을 하게 되는데, 이때 요 드라이브 내지 피치 드라이브에 부하가 발생하도록 테스트할 요 드라이브 또는 피치 드라이브에 대응하는 회전체를 설치한 테스트장치에 의해 성능을 검사하게 된다.Therefore, a test procedure for testing the performance of the yaw drive and the pitch drive is required before the yaw drive and the pitch drive are mounted in the wind generator. To this end, conventionally, the yaw drive and the pitch drive are continuously generated to perform forward and reverse cycle test of the yaw drive or the pitch drive, accelerated life test accommodating 120% of the rated torque, monitoring and recording drive torque. In this case, the performance is checked by a test apparatus provided with a rotating body corresponding to the yaw drive or the pitch drive to be tested to generate a load on the yaw drive or the pitch drive.
그러나, 상기와 같은 종래의 테스트장치는 테스트하고자 하는 요 드라이브 또는 피치 드라이브에 대응되는 회전체가 테스트장치에 설치되어야 하기 때문에 규격 및 성능을 달리하는 요 드라이브 또는 피치 드라이브를 테스트하고자 하는 경우에는 그에 대응되는 회전체를 테스트장치에 설치해야 하는 불편함이 있다.However, in the conventional test apparatus as described above, when a rotor corresponding to the yaw drive or pitch drive to be tested is to be installed in the test apparatus, the yaw drive or pitch drive having different specifications and performances is to be responded to. It is inconvenient to install the rotating body to the test apparatus.
특히, 요 드라이브 또는 피치 드라이브를 테스트하기 위해 테스트장치에 설치되는 회전체는 테스트하고자 하는 요 드라이브 또는 피치 드라이브와 유사한 구조를 갖기 때문에 그 하중이 무거워 회전체의 교체작업을 어렵게 할 뿐만 아니라 작동 중에 소음이 발생하는 문제가 있다.In particular, the rotor installed in the test apparatus for testing the yaw drive or pitch drive has a structure similar to that of the yaw drive or the pitch drive to be tested, so the load is heavy, making it difficult to replace the rotor and making noise during operation. There is a problem that occurs.
