Description

압축공기를 이용한 풍력발전 시스템Wind Power Generation System Using Compressed Air
본 발명은 바람을 이용하여 공기를 압축하고, 상기 압축된 공기를 이용하여 전력을 발생시키는 압축공기를 이용한 풍력발전 시스템에 관한 것이다.The present invention relates to a wind power generation system using compressed air that compresses air by using wind and generates electric power by using the compressed air.
일반적으로 풍력발전기는 바람에 의하여 회전하는 회전날개에 의하여 회전축을 회전시키고, 상기 회전축과 연결된 발전기의 축을 회전시켜 동력(전기)를 발전시키는 것으로, 보통 지면 또는 구조물에 안정적으로 수직으로 설치되는 하무몸체와, 상기 하부몸체의 상측에 회전하도록 설치되는 회전지지대와, 상기 회전지지대에 회전하도록 설치되는 회전축과, 상기 회전축에 직교방향으로 설치되는 다수개의 회전날개와, 상기 회전지지대 내측에 설치되고, 회전축과 연결 설치되어 동력을 발생시키는 발전기와, 상기 회전날개를 바람이 불어오는 방향으로 안내하는 보조날개로 이루어진 상부몸체로 구성된다.In general, a wind power generator rotates a rotating shaft by a rotary blade that is rotated by wind, and generates power (electricity) by rotating a shaft of the generator connected to the rotating shaft. And a rotation support installed to rotate on the upper side of the lower body, a rotation shaft installed to rotate on the rotation support, a plurality of rotation blades installed in a direction orthogonal to the rotation shaft, and installed inside the rotation support. It is connected to the generator is configured to generate power, and the upper body consisting of the auxiliary wing for guiding the rotary wing in the direction of the wind blowing.
상기 회전날개는 바람에 의하여 회전을 할 수 있도록 소정의 각도로 비틀어져 설치된다.The rotary blade is installed to be twisted at a predetermined angle to be rotated by the wind.
이와 같이 종래에 사용되고 있는 풍력발전기는 바람이 불 경우에만 회전날개를 회전시켜 전력(동력)을 발생시키고, 바람이 불지 않을 경우에는 회전날개를 회전시키지 못하여 전력(동력)을 발생시키지 못하는 단점이 있다.As described above, a wind power generator used in the related art generates power (power) by rotating the rotary blade only when the wind is blown, and does not generate power (power) by not rotating the rotary blade when the wind is not blown. .
또한, 바람의 세기에 따라 회전날개의 회전속도가 변화함으로써 발전기에서 발생하는 전력(동력)이 일정하지 못하는 단점과, 이로 인한 유효전력이 낮은 단점이 있다.In addition, there is a disadvantage that the power (power) generated by the generator is not constant by changing the rotational speed of the rotor blades in accordance with the wind strength, and the effective power is low due to this.
또한, 회전날개의 회전속도의 변화가 광범위하여 발전기(제너레이터)의 역시 이에 맞추어 설치되어야 함으로써 설치비용을 상승시키는 단점이 있으며, 발전기에서 발생하는 불규칙한 전력(동력)을 균일하게 하기 위한 보조장치가 필요한 단점이 있다.In addition, since the rotational speed of the rotor blades varies widely, the generator (generator) must be installed accordingly, thereby increasing the installation cost, and an auxiliary device for uniformizing irregular power (power) generated from the generator is required. There are disadvantages.
또한, 바람이 불 경우에만 전력(동력) 생산이 가능함으로써 수력발전기, 화력발전기 등과 같이 적기에 전력을 생산할 수 없는 단점이 있다.In addition, since the power (power) can be produced only when the wind is blowing, there is a disadvantage in that it cannot produce power in a timely manner such as a hydroelectric generator and a thermal power generator.
