일반적으로 풍력 발전시스템은 바람에 의한 운동 에너지를 전기적 에너지로 변환할 수 있도록 구성되는 시스템으로서, 설치되는 환경 조건에 따라 육상용(onshore)과 해상용(offshore)로 구분될 수 있다.In general, the wind power generation system is a system configured to convert the kinetic energy of the wind into electrical energy, it can be divided into onshore (offshore) and offshore (offshore) according to the installed environmental conditions.

다음은 첨부된 도면을 참조하며 본 발명을 보다 상세히 설명하겠다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings.

먼저, 도 1에 도시된 바와 같이, 본 발명의 풍력 발전기는 블레이드(110)를 갖는 허브(100)가 형성되고, 상기 허브(100)와 축 결합되는 메인샤프트(200)가 형성되며, 상기 메인샤프트(200)와 결합되는 로벨-바(300)가 형성된다.First, as shown in FIG. 1, in the wind generator of the present invention, a hub 100 having a blade 110 is formed, a main shaft 200 axially coupled to the hub 100 is formed, and the main A leveling bar 300 is formed which is coupled with the shaft 200.

이때, 상기 로벨-바(300)의 외측에는 S극과 N극이 원주방향을 따라 등간격으로 반복 배열되는 전기자 코일(400)이 형성되며, 상기 로벨-바(300)의 내측에는 베어링에 의해 메인샤프트(200)가 회전하면 운동에너지를 전기에너지로 변화하도록 하는 초전도 계자코일(Superconducting Field Coil: 500)이 형성된다.At this time, the armature coil 400 is formed on the outer side of the low-bar 300, the S pole and the N pole is repeatedly arranged at equal intervals along the circumferential direction, the inner side of the low-bar 300 by a bearing When the main shaft 200 rotates, a superconducting field coil 500 is formed to change kinetic energy into electrical energy.

이때, 상기 초전도 계자코일(500)의 일측에는 커플링 없이 직접 연결되어 초전도 계자코일(500)에 대하여 직접 냉각을 수행하도록 하는 극저온 냉동기(600)가 형성되어 이루어진다.At this time, one side of the superconducting field coil 500 is directly formed without a coupling to form a cryogenic refrigerator 600 to perform a direct cooling to the superconducting field coil 500.

이때, 상기 초전도 계자코일(500)은 권선된 외주면에 진공막(Vacuum Layer: 510)이 형성되고, 극저온 냉동기(600)와 대응되는 측부에는 극저온 냉동기(600)로부터 연결된 배관에 의해 진공막(510) 내부로 혼합 냉매(hybrid cryogens)가 공급될 수 있도록 하는 것이 바람직하다.At this time, the superconducting field coil 500 has a vacuum layer (Vacuum Layer: 510) is formed on the outer circumferential surface of the winding, and the vacuum membrane 510 by a pipe connected from the cryogenic freezer 600 to the side corresponding to the cryogenic freezer 600 It is desirable to allow hybrid cryogens to be supplied into the chamber.

또한, 상기 전기자 코일(400)은 구리 코일(Copper Coil)로서 로벨-바(300)가 자속을 끊으면 도체 양단에 전압이 유기되어 교류 전압이 발생되고, 유기된 유도 전압에 의해 상기 초전도 계자코일(500)에는 로벨-바(300)의 회전시 전기자 코일(400)과 자성에 의해 직류 전류가 흐르도록 하는 것이 바람직하다.In addition, the armature coil 400 is a copper coil (Copper Coil) when the low-bar 300 breaks the magnetic flux, the voltage is induced at both ends of the conductor to generate an alternating voltage, the superconducting field coil ( In the 500, the direct current flows by the armature coil 400 and magnetism when the leveling bar 300 rotates.

이에, 상기 극저온 냉동기(600)는 고온 저압의 기상 냉매를 저온 고압으로 압축하는 압축기와, 상기 압축기에서 압축된 냉매를 액상으로 응축하는 응축기와, 액상 냉매를 저압 액상 냉매로 팽창시키는 팽창밸브 및 상기 팽창밸브에서 팽창된 액상 냉매를 증발시키면서 외부의 열을 흡수하여 고온 고압의 기상 냉매를 압축기로 보내는 증발기가 구비되어 이루어진 것이 바람직하다.Accordingly, the cryogenic refrigerator 600 includes a compressor for compressing a high-temperature low-pressure gaseous refrigerant at low temperature and high pressure, a condenser for condensing the refrigerant compressed in the compressor into a liquid phase, an expansion valve for expanding the liquid refrigerant into a low pressure liquid refrigerant, and the It is preferable that an evaporator is provided to absorb the external heat while evaporating the liquid refrigerant expanded by the expansion valve and to send the high temperature and high pressure gaseous refrigerant to the compressor.

즉, 고온 가스가 등온 압축을 하면서 외부로 열을 방출하게 되면, 이 과정 동안에는 외부로 열을 방출하며 압축에 따른 냉매 가스의 온도 상승이 없게 되고, 가스가 재생기를 지나면서 냉각되어 팽창기 쪽으로 등적 이동하게 된다. 이 과정 동안에는 가스가 냉각되면서 재생기에 축열을 하게 된다.That is, when the hot gas emits heat to the outside while isothermally compressing, the heat is released to the outside during this process, and the temperature of the refrigerant gas is not increased due to the compression. Done. During this process, the gas cools and accumulates in the regenerator.

이후 저온 가스는 등온 팽창하면서 저온부로부터 열을 흡수하도록 형성되며 이 과정 동안에는 저온부로부터 열을 흡수하여 팽창에 따른 가스의 온도 강하가 없도록 형성된다.Thereafter, the low temperature gas is formed to absorb heat from the low temperature portion while isothermally expanding, and during this process, the low temperature gas is absorbed from the low temperature portion so that there is no temperature drop of the gas due to expansion.

이후 팽창기에 있는 저온 가스가 재생기를 통과하면서 가열되어 압축기 쪽으로 등적 이동하게 되고, 이 과정에서 재생기에 저장된 열은 가스 쪽으로 방열되는데 방열되는 양은 축열되는 양과 동일하다.Thereafter, the low temperature gas in the expander is heated while passing through the regenerator and is equally moved toward the compressor. In this process, the heat stored in the regenerator is radiated to the gas.

이러한 사이클이 반복됨에 따라 후속 사이클은 선행 사이클에 비하여 냉각부의 온도가 더 낮아지고, 냉동기의 최저 온도는 냉동 부하와 냉동 용량이 균형을 이루는 상태에서의 극저온 온도가 확보된다.
As this cycle is repeated, subsequent cycles have a lower temperature of the cooling section than the preceding cycle, and the lowest temperature of the refrigerator ensures a cryogenic temperature with a balance between the refrigeration load and the refrigeration capacity.
