도시형 풍력발전시스템용 풍력변환기{A wind converter for urban wind power generation system} {A wind converter for urban wind power generation system}

본 발명은 도시형 풍력발전시스템용 풍력변환기에 관한 것으로, 더욱 상세하게는 도시의 건물 등에 간편하고 안전하게 설치되고, 발전기를 구비한 발전장치와 연결되어 풍력을 동력으로 변화시켜 발전장치를 구동할 수 있는 구조를 갖도록 하는 도시형 풍력발전시스템용 풍력변환기에 관한 것이다.The present invention relates to a wind power converter for an urban wind power generation system, and more specifically, to a wind power converter that can be easily and safely installed in city buildings, etc., and is connected to a power generation device equipped with a generator to convert wind power into power to drive the power generation device. This relates to a wind power converter for an urban wind power generation system that has a structured structure.

일반적으로, 풍력발전기는 풍력으로 전력을 생산하는 것으로, 풍량이 풍부한 해상 또는 고지대에 설치된다.Generally, wind power generators produce electricity using wind power and are installed at sea or in highlands where wind volume is abundant.

풍력발전기은 다양한 형태가 있을 수 있으나, 최근 보편적으로 널리 보급되고 있는 것은 수평 풍력발전기 모델이다.Wind power generators can come in various forms, but the one that has recently become widespread is the horizontal wind power generator model.

이러한 수직 풍력발전기는 복수개의 회전날개로 구성되고, 풍력에 의해 회전되는 대형 프로펠러와 대형 프로펠러를 회전가능하게 지지하고 프로펠러의 회전으로 발생되는 회전력을 증폭시키는 회전력가속부와, 회전력가속부로 부터 전달되는 회전력에 의해 구동되어 전력을 생산하는 발전기로 이루어진 발전부와; 상기 발전부를 지지하는 지지대로 구성되어 있다.This vertical wind power generator consists of a plurality of rotary blades, a large propeller rotated by wind power, a rotational force accelerator that rotatably supports the large propeller and amplifies the rotational force generated by the rotation of the propeller, and a rotational force transmitted from the accelerator. A power generation unit consisting of a generator that is driven by rotational force to produce electric power; It consists of a support supporting the power generation unit.

이러한 구성은 국내 공개특허 제10-2088-0073045호(2008.08.08)에 구체적으로 게재되어 있다.This configuration is specifically disclosed in Korean Patent Publication No. 10-2088-0073045 (2008.08.08).

그러나, 상기와 같은 구성을 갖는 수직 풍력발전기는 프로펠러가 외부로 노출되어 회전됨으로 안전사고의 발생위험이 높고, 제작 및 설치비용이 고가이고, 그 부피가 매우 커 도시의 건물에 설치는데 적합하지 않을 뿐만 아니라 작동을 위해서는 매우 강한 풍속이 요구됨으로 도시의 건물에 설치하여 사용될 수 없다는 문제점이 있다. However, a vertical wind power generator with the above configuration has a high risk of safety accidents because the propeller is exposed to the outside and rotates, is expensive to manufacture and install, and is very bulky, making it unsuitable for installation in city buildings. In addition, since very strong wind speeds are required for operation, there is a problem that it cannot be installed and used in urban buildings.

본 발명은 상기와 같은 종래의 문제점을 고려하여 안출한 것으로서, 그 목적은 프로펠러의 외부노출 없이 약한 풍속으로도 작동이 가능하면서도 부피가 작고, 설치작업이 간편하여 제작 및 설치비용이 저렴함은 물론 복수개를 상호 조합 설치하여 동일 풍량에 대한 전력 생산비를 현지히 증대시킬 수 있는 도시형 풍력발전시스템용 풍력변환기를 제공하는 것이다.The present invention was developed in consideration of the above-described conventional problems, and its purpose is to enable operation even at low wind speeds without exposing the propeller to the outside, but to have a small volume and simple installation work, so that manufacturing and installation costs are low, as well as a plurality of devices.
