Description

철도차량에 설치되는 풍력발전장치{A WIND POWER APPARATUS ESTABLISHED IN TRAIN}Wind power generators installed on railway vehicles {A WIND POWER APPARATUS ESTABLISHED IN TRAIN}

본 발명은 철도차량에 설치되는 풍력발전장치에 관한 것으로서, 보다 상세하게는, 주행 중에 외부에서 발생하는 바람을 철도차량의 전기에너지로 사용할 수 있도록 한 철도차량에 설치되는 풍력발전장치에 관한 것이다. The present invention relates to a wind power generator installed in a railroad car, and more particularly, to a wind power generator installed in a railroad car so that the wind generated from the outside during driving can be used as electric energy of the railroad car.

최근 풍력 발전기는 전 세계적으로 대체 에너지로 각광받고 있으며, 그 잠재량은 연간 2만~5만 메가와트에 달하는 것으로 추정하고 있으며, 현재와 같은 추세대로 풍력 발전 시장이 확대되면 20여년 후에는 전세계 전기 수요의 10%가 풍력 발전으로 충당될 것이라는 예상도 있다. Recently, wind power generators are in the spotlight as alternative energy all over the world, and their potential is estimated to reach 20,000 ~ 50,000 megawatts per year. It is also estimated that 10% of the total will be from wind power.

또한 이러한 풍력발전기는 환경오염의 발생도 없으며, 설비 등을 단시간에 상쇄시킬 정도로 효율성도 양호하기 때문에 최근에는 국내에서도 제주도, 강원도 태백시 및 영월군 등에서 풍력발전기를 설치하고 있다. In addition, such a wind power generator has no environmental pollution, and the efficiency is good enough to offset the facilities in a short time, so recently, in Korea, wind power generators are installed in Jeju Island, Taebaek-si, Gangwon-do, and Yeongwol-gun.

이러한 풍력발전을 위해서는 대형 프로펠러를 설치하고, 상기 프로펠러의 회동에 의해 발전기에서 발전을 하도록 하는바, 주로 바람이 많은 지역, 즉 풍속이 약 4㎧ 이상인 곳에 설치하고 있으나, 항상 바람이 부는 것이 아니므로, 바람이 부는 때에만 발전을 하고, 바람이 없는 동안에는 발전을 할 수 없게 된다. In order to generate such wind power, a large propeller is installed and the generator is generated by the rotation of the propeller. The wind turbine is mainly installed in a windy area, that is, a wind speed of about 4 ㎧ or more, but the wind is not always blowing. They develop only when the wind is blowing, and they cannot develop while there is no wind.
