Description

태양광발전과 풍력발전이 결합된 발전기{PHOTOVOLTAIC AND WIND POWER COMBINED ELECTRIC GENERATOR}Generator that combines photovoltaic and wind power generation {PHOTOVOLTAIC AND WIND POWER COMBINED ELECTRIC GENERATOR}

본 발명은 태양광과 풍력을 함께 이용할 수 있는 발전기에 관한 것으로 더욱 상세하게는 태양광발전을 위한 태양전지패널과 풍력발전기가 3단으로 구성된 하나의 프레임에 함께 설치되고 운영되어 설치 및 운영비용을 줄이고 발전량을 최대화할 수 있는 발전기에 관한 것이다.The present invention relates to a generator that can use both solar and wind power, and more particularly, the solar panel and the wind power generator for photovoltaic power generation are installed and operated together in one frame composed of three stages. It is about a generator that can reduce and maximize power generation.

태양광발전은 태양전지를 부착한 패널을 이용하여 태양광에너지를 전류로 변환하여 전기를 생산하는 발전시스템이다. 이 발전의 특징은 반영구적이고 태양전지를 사용해서 유지와 보수가 간편하며, 무공해의 태양에너지원을 사용한다는 것이다. 그러나 태양광발전은 태양광을 에너지원으로 이용하는 관계로 일몰 후는 물론 구름이 낀 흐린 날씨나 비가 오는 경우에 발전이 계속되지 못하는 단점이 있다.Photovoltaic power generation is a power generation system that produces electricity by converting photovoltaic energy into electric current using panels attached with solar cells. The characteristics of this development are that it is semi-permanent, easy to maintain and repair using solar cells, and uses a pollution-free solar energy source. However, photovoltaic power generation has a disadvantage in that power generation does not continue after sunset as well as in cloudy weather or rain due to the use of sunlight as an energy source.

풍력발전기는 바람을 에너지원으로 하여 전기를 생산하는 기기이다. 바람의 힘에 의하여 회전하는 풍력터빈의 회전력으로 발전기를 돌려서 전기를 생산하므로 이 역시 무공해에너지에 해당하고 수력, 화력 및 원자력 발전과 비교하여 구조가 간단하고 유지와 보수가 용이하다는 장점이 있으나 자연환경에서 발생하는 바람을 에너지원으로 이용하는 관계로 발전이 불규칙하여 안정적이고 지속적인 전원으로 활용하기에 상당한 문제점이 있다.A wind turbine is a device that produces electricity by using wind as an energy source. Electricity is generated by turning a generator by the rotational force of a wind turbine that is rotated by the force of wind. This is also a pollution-free energy and has the advantages of simple structure and easy maintenance and repair as compared to hydro, thermal and nuclear power. Due to the use of wind generated as a source of energy in the power generation is irregular, there is a significant problem to use as a stable and sustainable power source.

둘째, 태양광발전의 경우 야간이나 흐린 날의 경우 발전이 사실상 불가능한데 이때 풍력발전이 계속될 수 있으며, 반대로 바람이 전혀 불지 않아서 풍력발전이 불가능한 경우의 맑은 날씨에서는 태양광발전이 가능하므로 두 가지 발전기가 상당부분 발전의 연속성을 상호 보완해 줄 수 있다.Secondly, in the case of solar power generation, it is virtually impossible to generate electricity at night or on a cloudy day. At this time, wind power generation can continue. Generators can complement each other's continuity of power generation.

세째, 컨트롤시스템에 연결된 배터리는 두 가지 발전기에서 생산되는 잉여전기를 직류로 변환하여 축전할 수 있으며, 두 가지 발전기가 동시에 발전이 중지되는 경우에 배터리에 축전된 전기를 인버터를 거쳐서 교류전기로 출력하면 지속적인 발전상태가 유지되게 된다. Third, the battery connected to the control system can convert the surplus electricity produced by the two generators into direct current and accumulate it. When the two generators are stopped at the same time, the electricity stored in the battery is output to the alternating current through the inverter. If you do, the state of continuous development will be maintained.
