Abstract
본 고안은 소형 풍력발전기의 자동과속방지장치에 관한 것으로, 소형 풍력발전기에 있어서 한계 풍속이상의 경우 발전기 회전이 빨라져 충전할 수 없는 높은 전압과 과전류가 발전될 경우에 자동적으로 발전 전압을 감지하여 발전기에서 나오는 출력선을 단락시킴으로 발전기 회전을 멈추게 하여 발전기와 충전회로 및 축전지등의 전체 풍력발전시스템의 전기적, 기계적 손상을 자동적으로 보호하는 장치이다.The present invention relates to an automatic overspeed prevention device of a small wind power generator. In a small wind power generator, the generator rotates faster when the wind speed exceeds the limit wind speed. It is a device that automatically protects electrical and mechanical damage of the whole wind power generation system such as generator, charging circuit and storage battery by stopping generator rotation by shorting output line.

Description
도 1은 본 고안에 따른 자동과속방지장치의 흐름도1 is a flow chart of the automatic speed prevention device according to the present invention
(1)발전기 (2)전력분배기 (3)1차 저항 (1) generators (2) power dividers (3) primary resistors
(4)2차 저항 (5)3차 저항 (6) 단락선(4) Secondary resistance (5) Tertiary resistance (6) Short circuit
일반적으로 종래까지의 소형풍력발전기에는 강풍이나 폭풍으로 인한 과속회전시 브레이드의 피치제어나 실속등에 의존하여 발전기의 과속회전을 방지하는 장치가 있으나 소형 풍력발전기에서는 효과적으로 과속에 대처하지 못하고 있다. 대부분 소형 풍력발전기는 수동으로 발전기 출력회로를 단락시켜서 발전기 회전을 멈추어 발전시스템을 보호하는 것이다. 소형풍력 발전기의 설치 특성상 강풍이나 폭풍시 즉시 감지하고 수동으로 발전기 출력회로를 단락시키기 불가능하며, 한계 풍속이상에서 출력제한 방법이 없어 발전기와, 충전기, 축전기등의 발전 시스템에 많은 손상을 입고 있는 실정이다.In general, the conventional small wind power generator has a device that prevents overspeed rotation of the generator depending on the pitch control or stall of the braid during the overspeed rotation due to the strong wind or storm, but the small wind power generator does not effectively cope with the overspeed. Most small wind turbines manually short the generator output circuitry to stop the generator from rotating and protect the power generation system. Due to the installation characteristics of small wind power generators, it is impossible to detect a strong wind or storm immediately and manually short-circuit the output circuit of the generator.There is no output limit method above the limit wind speed. to be.
본 고안은 상기 제반 문제점을 해결하기 위해 고안된 것으로, 소형 풍력발전기에 자동과속 방지장치를 설치하여 강풍시 풍력발전기를 보호하고 강풍이나 돌풍시 자동적으로 제너레이터 회로를 차단하여 블레이드와 제너레이더의 회전을 멈추게 함으로서 발전시스템의 완벽한 보호를 유지할 수 있게 하는 것이다.The present invention is designed to solve the above problems, by installing an automatic speed protection device in a small wind power generator to protect the wind generator during strong winds and to automatically stop the generator circuit during strong winds or gusts to stop the rotation of the blades and the generator radar. By doing so, it is possible to maintain complete protection of the power generation system.
이하, 본 고안의 실시 예를 첨부된 도면을 참조하여 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
도 1에 도시된 바와 같이 풍력발전기의 발전기(1)에서 나온 출력선의 전압을 감지하여 설정전압이상 출력될 시에 전력분배기(2)를 통하여, 1차저항(3), 2차저항(4), 3차저항(5)에 단계적으로 연결되어 최종 출력회로를 단락시켜 발전기의 회전을 정지시킨다.As shown in FIG. 1, the primary resistor 3 and the secondary resistor 4 are sensed through the power divider 2 when the voltage of the output line from the generator 1 of the wind generator is sensed and outputted above the set voltage. It is connected to the tertiary resistor (5) step by step to short circuit the final output circuit to stop the rotation of the generator.
상술한 바와 같이 본 고안에 의하면 자동과속방지장치를 설치함으로 태풍 및 돌풍등의 강한 바람에도 풍력발전기의 기계적, 전기적 손실을 막을 수 있으며, 소형 풍력발전기에도 대형풍력발전기와 같이 안정적으로 사용할 수 있는 효과가 있다.As described above, according to the present invention, the automatic speed preventing device can be installed to prevent mechanical and electrical losses of the wind turbine even under strong winds such as typhoons and gusts, and can be used stably in small wind turbines as well as large wind turbines. There is.
