본 발명은 집광판을 이용한 태양광 발전과 바람을 이용한 풍력 발전을 통해 발전을 하는 태양광과 풍력 발전의 복합발전 장치에 관한 것으로서, 보다 상세하게는 태양광을 이용하여 직류 전기를 발생시키는 태양광 발전과 바람의 힘에 의해 교류 전기를 발생시키는 풍력 발전을 동시에 구동함으로서 발전 효율을 향상시켜 전력을 공급하도록 하는 태양광과 풍력 발전의 복합발전 장치에 관한 것이다. The present invention relates to a combination of photovoltaic power generation and wind power generation using photovoltaic power generation using a light collecting plate and wind power generation using wind, and more particularly, photovoltaic power generation using direct sunlight to generate direct current electricity. The present invention relates to a combination of solar and wind power generation apparatuses that provide power by improving power generation efficiency by simultaneously driving wind power generating alternating electricity by the force of wind and wind.

종래의 화석 에너지는 자연 환경의 오염을 발생시켰고 근래에는 지하 자원의 고갈로 인하여 풍력, 태양광 등의 대체 에너지를 이용한 발전에 대한 관심이 증가하고 있다. 이에 따라 풍력 발전, 태양광 발전 분야가 집중적으로 연구되고 있지만 두 발전 방식에 따른 장,단점이 서로 상이하여 에너지 효율이 매우 좋지 못하였다. 풍력 발전의 경우 한 여름같이 매우 더우면 바람이 불지 않기 때문에 효율이 급격하게 떨어지는 문제점이 있고 태양광 발전의 경우 밤이나 날씨가 흐린 때 그리고 외부의 먼지등으로 인하여 효율이 급격하게 떨어지는 문제점이 있다. Conventional fossil energy has caused pollution of the natural environment, and recently, due to the depletion of underground resources, interest in power generation using alternative energy such as wind and solar light is increasing. As a result, the fields of wind power and solar power have been intensively studied, but the energy efficiency was not very good due to the advantages and disadvantages of the two generation methods. In the case of wind power, there is a problem that the efficiency is drastically dropped because the wind is not blown when it is very hot, such as in the summer, and in the case of solar power, there is a problem that the efficiency is drastically decreased due to dust or dust at night or weather.

본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 발명된 것으로서 본 발명이 이루고자 하는 기술적 과제는 풍력 발전과 태양광 발전의 장점과 단점을 서로 보완하여 발전을 진행함으로써 발전 효율을 향상시키는 데 있다.The present invention has been invented to solve the above-mentioned conventional problems, and the technical problem to be achieved by the present invention is to improve the power generation efficiency by progressing the power generation by complementing the advantages and disadvantages of wind power and photovoltaic power generation.

상기와 같은 목적을 달성하기 위하여 본 발명의 바람직한 실시 예에 따른 태양광과 풍력발전의 복합발전장치는, 풍력과 태양광을 이용하여 동시에 발전을 진행하며 태양광 집광판을 풍력 발전기의 회전 날개에 장착함으로서 태양광의 발전 효율을 향상시키는 것으로서 보다 자세한 내용은 첨부된 도면을 참조로 하여 설명한다. In order to achieve the above object, the solar cell and the wind power generator according to a preferred embodiment of the present invention, the wind power and the solar power generation at the same time progress the solar light collecting plate mounted on the rotary blades of the wind generator By improving the power generation efficiency of the solar light will be described in more detail with reference to the accompanying drawings.

도 1은 종래의 태양광 발전 시스템의 구성도로서 태양광이 집광판으로 빛을 전달하면 집광판에서 집광판의 배열과 연결에 따라 직류 전기의 량이 달리 발생한다. 발생한 직류 전기는 축전지에 충전되며 동시에 직류/교류변환기를 통하여 교류 전기로 변환된다. 교류로 변환된 교류 전기는 일반적으로 사용할 수 있는 교류 전기로서 전기기기를 동작시킨다. 또한 태양광 발전기의 발전량이 전기기기를 동작시 키고 남는 량은 축전지에 계속 충전되게 된다. 그리고 날씨가 흐리거나 태양이 없는 밤 또는 비나 눈으로 인하여 집광판에 태양광이 전달되지 못하면 축전지에 충전되어 있던 직류 전기가 직류/교류변환기를 통해 전기기기를 동작시킬 수 있도록 한다. 하지만 축전지의 용량이나 태양광 집광판의 용량, 주위의 발전 환경에 따라 장시간 태양광 발전을 하지 못하는 경우가 자주 발생하여 발전량이 매우 유동적이다. 1 is a configuration diagram of a conventional photovoltaic power generation system, when sunlight transmits light to a light collecting plate, the amount of DC electricity is generated differently according to the arrangement and connection of the light collecting plate in the light collecting plate. The generated direct current is charged in the battery and simultaneously converted into alternating current through a direct current / AC converter. The alternating current electricity converted to alternating current is an alternating current electricity which can be used to operate an electric device. In addition, the amount of power generated by the solar generator to operate the electric equipment and the remaining amount will continue to be charged in the battery. And when sunlight is not transmitted to the light collecting plate due to cloudy weather, sunless night, or rain or snow, the direct current charged in the battery can operate the electric device through the DC / AC converter. However, depending on the capacity of the battery, the capacity of the solar light collecting plate, and the surrounding power generation environment, it is often impossible to generate photovoltaic power for a long time, and the power generation is very flexible.

도 2는 종래의 풍력 발전 시스템의 구성도로서 풍력 발전기의 회전 날개가 바람에 의해 회전하게 되면 기어의 배율에 의해 발전기가 회전을 하게 된다. 이때 발생하는 전기는 교류 전기로서 매우 유동적인 전기이다. 이를 보완하기 위해 발생된 교류 전기는 교류/직류 변환기를 통해 일정한 직류 전기로 변환되며 이를 다시 직류/교류 변환기로 변환 시켜 전기기기를 동작시킬 수 있는 교류 전기를 발생시킨다. 교류/직류 변환기에 의해 변환된 직류 전기는 전기기기를 동작시키기 위한 전기를 공급하고 남은 전기는 축전지에 충전되며 풍력 발전기가 발전을 멈추거나 발전의 량이 부족하게 되면 축전지에 충전되어 있던 직류 전기가 직류/교류 변환기에 의해 교류로 변환되어 전기기기를 동작시킨다. 하지만 풍력 발전기의 특성상 바람이 불지 않으면 발전이 이루어 지지 않으며 날씨와 계절 및 설치 장소에 따라 발전 량이 매우 유동적이다. 2 is a configuration diagram of a conventional wind power generation system, when the rotor blades of the wind generator rotate by the wind is the generator rotates by the magnification of the gear. The electricity generated at this time is alternating current electricity, which is very fluid. AC electricity generated to compensate for this is converted into a constant DC electricity through an AC / DC converter and converts it into a DC / AC converter to generate AC electricity to operate the electric equipment. The DC electricity converted by the AC / DC converter supplies electricity to operate the electric equipment, and the remaining electricity is charged to the battery. When the wind generator stops generating electricity or the amount of electricity is insufficient, the DC electricity stored in the battery is applied. It is converted into alternating current by the alternating current converter to operate the electric machine. However, due to the characteristics of wind generators, power generation does not occur unless the wind blows, and the power generation is very flexible depending on the weather, season, and installation place.

도 3은 본 발명의 실시 예에 따른 복합발전장치의 구성도로서 풍력 발전과 태양광 발전을 동시에 진행함으로써 상호 단점인 유동적인 발전을 보완하고 발전량을 극대화하며 발전 설비를 최소화할 수 있도록 하였다. 바람이 있을 때에는 풍력 발전기가 발전을 하여 도 2에서 설명한 바와 같이 발전을 진행하며 태양이 있을 때 에는 태양광을 집광판이 집광하여 도 1에서 설명한 바와 같이 발전을 진행한다. 바람과 태양이 동시에 있을 경우 최대의 발전을 하지만 두 가지 중 한 가지만 있어도 발전을 하기 때문에 발전 효율이 향상된다. 아울러 종래에 태양광 발전의 경우 밤이 되거나 태양이 없는 흐린 날 외에도 눈이나 먼지가 집광판을 덮으면 발전이 이루어 지지 않지만 본 발명에 의해 집광판을 풍력 발전기의 회전 날개에 설치를 하면 눈이나 먼지가 쌓여 태양광 발전의 효율이 떨어지는 것을 방지할 수 있다. 그리고 한 개의 축전기와 제어 / 보호부 로서 두 가지 발전을 동시에 제어하여 발전을 하기 때문에 발전 설비 장착의 비용을 절감할 수 있다. 3 is a configuration diagram of a hybrid power generation apparatus according to an embodiment of the present invention by simultaneously performing wind power and photovoltaic power generation to complement the mutual disadvantages of flexible power generation, maximize the amount of power generation and minimize the power generation equipment. When there is wind, the wind generator generates power and proceeds as described in FIG. 2, and when there is the sun, the light collecting plate collects sunlight and proceeds as described in FIG. 1. If the wind and the sun are at the same time the maximum power generation, but only one of the two generations of power generation efficiency is improved. In addition, in the case of photovoltaic power generation in the past, in addition to the night or the cloudy day without the sun, if the snow or dust covers the light collecting plate, the power generation does not occur, but when the light collecting plate is installed on the rotor blades of the wind power generator according to the present invention, The efficiency of photovoltaic power generation can be prevented from falling. In addition, as a capacitor and a control / protection unit control two generations at the same time, the cost of installing a power generation facility can be reduced.

풍력 발전에 의해 발생된 교류 전기는 교류/직류 변환기를 통해 직류로 변환되고 직류/교류 변환기에 의해 전기기기를 동작시키는 교류 전기를 발생시키고 남은 잔량의 전기는 축전지에 저장된다. 아울러 태양광 발전에 의해 발생된 직류 전기는 직류/교류 변환기에 의해 교류로 변환되어 전기기기를 동작시키는 교류 전기를 발생시키고 남은 잔량의 전기는 축전지에 저장된다. 이와 같이 상호 단점을 보완할 수 있도록 설계된 태양광과 풍력발전의 복합발전장치는 발전 량이 유동적이지 않도록 꾸준히 발전을 진행하여 발전 효율을 극대화할 수 있다.The alternating current generated by wind power generation is converted into direct current through an alternating current / direct current converter, and generates alternating current electricity for operating the electric device by the direct current / alternating current converter. The remaining amount of electricity is stored in the battery. In addition, direct current electricity generated by solar power is converted into alternating current by a DC / AC converter to generate alternating current electricity to operate the electric device, and the remaining amount of electricity is stored in the battery. As such, the combined power generation system of solar power and wind power generation designed to make up for the shortcomings of each other can maximize power generation efficiency by continuously generating power so that power generation is not fluid.

본 발명은 각각의 발전이 동시에 진행될 수 있도록 되어 있어 발전 효율이 극대화되고 이에 필요한 기본 시설을 겸용으로 이용하여 복합 발전 장치를 만들 수 있으므로 경비를 절감하게 하고, 자연 환경이 유동적인 국내 환경에 적합하게 사용할 수 있다.The present invention is to be able to proceed with each power generation at the same time to maximize the power generation efficiency and can be combined with the basic facilities required to make a complex power generation device to reduce the cost, and to suit the domestic environment that the natural environment is flexible Can be used.
