본 발명은 풍력발전기용 풍차에 관한 것으로, 더욱 상세하게는 미풍에서도 회전이 가능하며, 풍차의 회전속도를 더욱 빠르게 함으로써 발전량을 증가시킬 수 있는 풍력발전기용 풍차에 관한 것이다.The present invention relates to a windmill for wind turbines, and more particularly, to a wind turbine for wind turbines, which can be rotated even in a breeze and can increase the amount of power generated by making the rotation speed of the windmill even faster.

일반적으로 풍력발전이란 공기의 유동이 가진 운동 에너지의 공기역학적(aerodynamic) 특성을 이용하여 회전자(rotor)를 회전시켜 기계적 에너지로 변환시켜서 전력을 얻는 기술로서, 풍력 발전기는 지면에 대한 회전축의 방향에 따라 수평형 및 수직형으로 분류되고, 주요 구성 요소로는 날개와 허브로 구성된 회전자와, 상기 회전자의 회전을 증속하여 발전기를 구동시키는 증속 장치, 발전기 및 각종 안전 장치를 제어하는 제어 장치, 유압 브레이크 장치와 전력 제어 장치 및 철탑 등으로 구성된다.In general, wind power is a technology that obtains power by converting a rotor into mechanical energy by using the aerodynamic characteristics of the kinetic energy of air flow. According to the horizontal and vertical type, the main component is a rotor consisting of a blade and a hub, and a control device for controlling the speed increaser for driving the generator by increasing the rotation of the rotor, generator and various safety devices , Hydraulic brake device, power control device and steel tower.

또한 풍력발전은 어느 곳에나 산재 되어 있는 무공해, 무한정의 바람을 이용하므로 환경에 미치는 영향이 거의 없고, 국토를 효율적으로 이용할 수 있으며, 대규모 발전 단지의 경우에는 발전 비용도 기존의 발전 방식과 경쟁 가능한 수준의 신 에너지 발전 기술이다.In addition, wind power generation uses no-pollution and infinite wind scattered everywhere, so there is little effect on the environment, and the land can be used efficiently, and in the case of large-scale power generation facilities, power generation costs can compete with existing power generation methods. Level of new energy generation technology.

종래에 이와 같이 풍력 발전기에서 풍차는 바람에 의해 회전되는 운동 에너지를 이용해서 전기 에너지로 바꾸게 되는데, 이때 풍차의 이론상 운동 에너지 중 약 60% 정도 만이 전기 에너지로 바뀔 수 있는데 이것도 풍차의 형상에 따른 효율, 기계적인 마찰, 발전기의 효율 등을 고려하면 실제로 20 ~ 40% 만이 전기 에너지로 이용할 수 있으며, 따라서 시설규모에 비하여 발전량이 적다는 문제점이 있다.Conventionally, in the wind generator, the windmill is converted into electrical energy by using kinetic energy rotated by the wind. At this time, only about 60% of the theoretical kinetic energy of the windmill can be converted into electrical energy. In consideration of mechanical friction, generator efficiency, and the like, only 20-40% of the energy can be used as electrical energy.

또한, 지역적으로 바람이 적은 곳에서나, 미풍에는 풍차가 회전하지 않아 매우 비효율적이라는 문제점도 있다.In addition, there is a problem that the windmill does not rotate in the place where the wind is low, the breeze is very inefficient.
