Description

풍력 발전 장치용 로터 블레이드 {Rotor blade for wind force development device}Rotor blade for wind force development device

본 발명은 수평축 풍력발전시스템의 블레이드에 관한 것으로서 보다 상세하게는 풍력발전기의 타워에서 수평축 풍력 발전시스템을 기울게 하여 수평형 블레이드 끝에 별도의 블레이드를 고정 시킴으로서 수평형 블레이드가 회전하면서 부딛치는 바람의 손실을 최소화하고 정면에서 부는 바람과 옆바람의 풍속을 받아 2∼3㎧이하의 저풍속(이하 2∼3㎧이하의 풍속을 "저풍속" 이라 통칭함) 에서도 수평축 풍력발전시스템의 회전력을 유도하여 높은 출력의 전압을 발전하는 효과가 있는 풍력발전시스템에 관한 것이다.The present invention relates to a blade of a horizontal axis wind power generation system, and more particularly, by tilting the horizontal axis wind power generation system in a tower of a wind turbine, and fixing a separate blade at the end of the horizontal blade to reduce the loss of wind caused by the horizontal blade rotating. High output by inducing rotational power of horizontal axis wind power generation system even at low wind speed of 2 ~ 3㎧ or less (hereinafter referred to as “low wind speed”) by receiving wind from front and side wind. The present invention relates to a wind power generation system having an effect of generating a voltage of.

일반적으로 산업발달 및 인구증가에 의해 에너지부족의 대체 에너지원으로 태양광발전, 소수력, 파력, 조류발전, 지열등 신재생 에너지에 관한 많은 연구가 진행되고 있다.In general, many studies on renewable energy such as photovoltaic power generation, small hydro power, wave power, tidal power generation, geothermal power, etc. are being conducted as alternative energy sources due to energy development due to industrial development and population growth.

한편 풍력발전시스템(WTGS:Wind Turbine Generater System)은 수평축 풍력터빈(HAWT:Horizontal Axis Wind Turbine)과 수직축풍력터빈(VAWT:Vertical Axis Wind Turbine)의 발전장치에서 전기에너기로 바꾸어주는 신재생 에너지에 관한 것 으로 많은 나라에서 풍력발전시스템이 이루어지고 있으나 기존의 풍력발전시스템에 지형적인 요인과 자연환경으로 인하여 2∼3㎧이상의 평균적인 바람이 불지 않으면 풍력발전시스템의 증속기 기어마찰로 저풍속에서는 블레이드의 회전이 원활하지 못하여 발전이 이루어지지 않고 있다.On the other hand, the Wind Turbine Generater System (WTGS) is a new generation of renewable energy that converts electrical energy into electrical energy in power generation units of horizontal axis wind turbines (HAWT) and vertical axis wind turbines (VAWT). In many countries, wind power generation systems are being implemented. However, if the wind power of the existing wind power generation system does not blow more than 2 ~ 3㎧ of the average wind due to the topographical factors and the natural environment, the gear generator friction of the wind power generation system may cause the blades to operate at low wind speed. The rotation of the power is not smoothly generated.

그리고 2∼3㎧이상의 풍속에서 발전을 한다, 하여도 발전장치의 발전량이 적어 발전량을 올리기 위해 풍력발전시스템이 대형화 되어 가고 있으며 이는 생산되는 발전량에 비해 많은 면적과 대규모의 설치비용이 요구되고 있다.And even if the wind power is generated at wind speeds of 2 ~ 3 ㎧ or more, the amount of power generated by the power generator is small, and the wind power generation system is becoming larger in order to increase the amount of power generated.

이를 해결하기 위해 많은 선행기술이 이루어져 있으며 종래의 공개 일본 PAJ JP 2004-108306A 와 PCT WO 02/086312 A1 의 기술은 회전축과 직교할 방향으로 장착된 복수의 프로펠라형 날개로 구성되어 고풍속시 고회전 으로 원심력에 의한 블레이드 끝의 프로펠라형 날개가 날아가 인근에 많은 피해가 우려 되며 유럽공개 EP PD 00086076 A1 하는 기술은 과도한 속도제어 및 피치제어를 자제하고 로우터의 각고회전 속도에 있는 고속요동으로 인한 정격 전압과 주파수 파동을 감소키고 피치 제어를 하도록 이루어져 있으나 블레이드의 중간 블레이드로 인해 많은 저항과 고회전시 자칫 블레이드의 파손으로 큰 효과를 기대 할 수 없는 문제점이 있었다.In order to solve this problem, many prior arts have been made. The techniques of the prior arts, JP PA-JP JP 2004-108306A and PCT WO 02/086312 A1, consist of a plurality of propeller-type blades mounted in a direction orthogonal to the axis of rotation. The propeller blades of the blade tip are blown away by centrifugal force, causing a lot of damage in the vicinity. The European EP EP 00086076 A1 technology avoids excessive speed control and pitch control, and the rated voltage due to the high-speed fluctuation at the angular rotational speed of the rotor It is made to reduce the frequency fluctuation and control the pitch, but due to the middle blade of the blade, there was a problem that can not expect a large effect due to the damage of the blade at high rotation.

본 발명은 상기와 같은 종래기술의 문제점을 고려하여 이루어진 것으로 지형적 환경 요인에 의한 저풍속에서도 초기 기동에 있어 유리하고 고출력의 전기를 공급 하는데 있어 생산 되는 발전량에 비해 많은 면적과 대규모의 설치비용을 절감하 는데 그 목적이 있다.The present invention has been made in consideration of the problems of the prior art as described above, which is advantageous for initial start-up even at low wind speed due to the topographical environmental factors, and saves a large area and a large installation cost compared to the amount of power produced to supply high-power electricity. Its purpose is to.
