변전소 여유전원 저장용 발전장치{Power generation device for storage of spare power in substation}Power generation device for storage of spare power in substation

본 발명은 변전소 여유전원 저장용 발전장치에 관한 것으로, 보다 상세하게는 변전소 주변을 밝히는 가로등을 상용전원이 아닌 자연에너지로부터 얻은 전기를 사용하여 밝힘으로써 에너지 절감은 물론 친환경 에너지 개발에 기여할 수 있도록 하면서 가로등 외에도 변전소 외부에서 상용전원이 아닌 저장전원을 이용하여 변전소 관리에 필요한 부대 전원으로 활용할 수 있도록 개선된 변전소 여유전원 저장용 발전장치에 관한 것이다.The present invention relates to a power generation device for storing redundant power in a substation, and more particularly, by illuminating a street lamp illuminating the vicinity of a substation using electricity obtained from natural energy rather than commercial power, saving energy as well as contributing to eco-friendly energy development. In addition to streetlights, it relates to an improved substation spare power storage generator so that it can be used as ancillary power required for substation management by using stored power, not commercial power, outside the substation.

변전소는 발전소에서 보내 오는 전기의 전압을 높이거나 낮추어서 알맞은 전압으로 바꾸어 보내는 곳 또는 그 시설로서, 초고압 변전소·1차 변전소·2차 변전소·배전용 변전소 등으로 나뉜다.A substation is a place or facility that raises or lowers the voltage of electricity sent from a power plant and converts it to an appropriate voltage, or its facility.

수력발전소나 화력발전소 그리고 원자력발전소에서 일으키는 전기는 일단 가까이 있는 1차 변전소로 보내진다.Electricity generated by hydroelectric power plants, thermal power plants, and nuclear power plants is first sent to a nearby primary substation.

그리고, 1차 변전소에서는 변압기로 전압을 높여 고압 전선으로 먼 곳까지 보낸다.And, in the primary substation, the voltage is increased by a transformer and sent to a distant place with a high-voltage wire.

이때, 고압 전력은 도시나 큰 공장 가까이 있는 2차 변전소에서 다시 전압을 낮추어 소비자에게 저압 전선으로 송전하며, 변압기 안에는 고압 코일과 저압 코일이 있어서 전압을 높이거나 낮출 수 있고, 전압을 일정하게 보내는 장치가 되어 있다.At this time, the high-voltage power is lowered again in a secondary substation near a city or a large factory and transmitted to the consumer through a low-voltage wire. has become

한편, 지구환경을 보호하고 온난화 방지를 위해 정부 주도하에 민간과 함께 다양한 친환경 에너지를 개발하려는 노력들이 경주되고 있다.Meanwhile, efforts are being made to develop various eco-friendly energies together with the private sector under the leadership of the government to protect the global environment and prevent global warming.

하지만, 공공기관에 해당하는 한국전력이 운용하는 발전이나 변전 분야에서는 이에 대한 적극적인 참여가 없는 실정이다.However, there is no active participation in the power generation or substation field operated by KEPCO, which is a public institution.

뿐만 아니라, 변전소 주변에서 청소용 카트를 운행한다든지 잔디를 깍는다는지 변전소 관리에 부대되는 작업에 필요한 장비를 사용할 때도 일반 상용전원을 사용하여 충전하였기에 이또한 에너지 절감이 필요한 상황이다.In addition, when operating a cleaning cart around the substation, mowing the lawn, or using the equipment necessary for substation management, it is charged using a general commercial power source, so energy saving is also required.

In this case, it is preferable that the second permanent magnet 248 is embedded in a state in which it is cut in half in the radial direction.

뿐만 아니라, 상기 회전통(240)의 외주면에는 수평부재(250)가 일체로 형성된다.In addition, the horizontal member 250 is integrally formed on the outer circumferential surface of the rotary tube 240 .

그리고, 상기 수평부재(250)의 상면에는 지주(260)가 고정되고, 상기 지주(260)의 상단에는 제너레이터(270)가 고정되며, 상기 제너레이터(270)에는 블레이드(280)가 설치된다.A post 260 is fixed to an upper surface of the horizontal member 250 , a generator 270 is fixed to an upper end of the post 260 , and a blade 280 is installed to the generator 270 .

그리하여, 바람이 불면 블레이드(280)가 회전하면서 제너레이터(270)를 돌려 전기를 생산하게 되며, 생산된 전기는 ESS(300)로 저장되어 상술한 바와 같이 가로등(400)을 밝히는 전원으로 사용된다.Thus, when the wind blows, the blade 280 rotates and turns the generator 270 to produce electricity, and the produced electricity is stored in the ESS 300 and used as a power source to illuminate the street lamp 400 as described above.

이와 같은 구조를 갖게 되면 수평부재(250) 자체가 바람의 방향에 따라 회전하기 때문에 그 위에 블레이드(280)를 다수개 설치할 수 있기 때문에 그 만큼 발전효율을 증대시킬 수 있다.When having such a structure, since the horizontal member 250 itself rotates according to the direction of the wind, a plurality of blades 280 can be installed thereon, thereby increasing the power generation efficiency.

그 외 배선 등의 문제는 꼬이지 않도록 로터리죠인트와 슬립링을 사용하여 공지의 방식을 적용하여 해결할 수 있으므로 본 발명에서는 구체적인 언급을 생략한다.Other problems, such as wiring, can be solved by applying a known method using a rotary joint and a slip ring so as not to be twisted, so a detailed description thereof will be omitted in the present invention.

덧붙여, 도 4의 예시와 같이 상기 지주(260)의 상단에는 제너레이터(270)의 반대방향으로 수직꼬리편(290)을 더 설치하여 바람의 방향에 따라 상기 회전통(240)이 더 원활하게 자동정렬하도록 하여 발전효율을 더욱 높일 수 있도록 구성될 수 있다.In addition, as in the example of FIG. 4 , a vertical tail piece 290 is further installed in the opposite direction of the generator 270 at the upper end of the post 260 so that the rotary tube 240 automatically automatically operates according to the direction of the wind. It may be configured to further increase the power generation efficiency by sorting.

이때, 수직꼬리편(290)은 지주(260) 상에 볼트체결되는 구조를 가질 수 있다.At this time, the vertical tail piece 290 may have a structure in which the bolt is fastened on the post 260 .

또한, 바람의 방향을 쉽게 확인하고 저항력을 높여 회전통(240)의 회전원활성을 확보하도록 상기 수평부재(250) 상에는 방향타깃발(FLG)이 더 설치될 수 있다.In addition, a direction target flag (FLG) may be further installed on the horizontal member 250 to easily check the direction of the wind and increase the resistance to secure the rotational activity of the rotary tube 240 .

상기 방향타깃발(FLG)은 일종의 천으로 이루어지며, 바람을 받게 되면 펄럭거리면서 저항을 생기게 히므로 블레이드(280)를 바람 불어오는 방향으로 정렬시키는데 매우 유용하다.The direction target (FLG) is made of a kind of cloth, and when it receives wind, it flaps and generates resistance, so it is very useful for aligning the blades 280 in the direction in which the wind blows.

이에 더하여, 본 발명에서는 도 5의 예시와 같이, 시공상 용이성과 편리성을 위해 상기 고정포스트(210)의 하단은 지지포스트(PST)에 끼워지며, 상기 지지포스트(PST)는 끼움돌기(212)에 끼워지고, 상기 끼움돌기(212)는 원판(214)의 중심에서 돌출되며, 상기 원판(214)은 상기 지붕(100) 표면에 앵커볼트로 견고하게 고정된다.In addition, in the present invention, as shown in the example of FIG. 5 , the lower end of the fixing post 210 is inserted into the support post PST for ease and convenience in construction, and the support post PST is a fitting protrusion 212 . ), and the fitting projection 212 protrudes from the center of the disk 214 , and the disk 214 is firmly fixed to the surface of the roof 100 with anchor bolts.

또한, 상기 끼움돌기(212)에는 직경방향으로 관통된 돌기핀공(216)이 형성되고, 이와 대응되는 위치의 지지포스트(PST) 상에는 포스트핀공(218)이 형성되어 지지포스트(PST)를 끼움돌기(212)에 끼운 후 볼트(BT)와 너트(NT)를 이용하여 돌기핀공(216)과 포스트핀공(218)에 끼워 체결하면 조립 시공이 편리하고 용이하며 빠른 설치가 가능하고 언제든지 유지보수하기 쉬운 형태의 고정포스트(210) 설치구조를 갖게 된다.In addition, the fitting protrusion 212 is formed with a protrusion pin hole 216 penetrating in the radial direction, and a post pin hole 218 is formed on the support post PST at a position corresponding thereto to insert the support post PST. After inserting into the 212, the bolt (BT) and the nut (NT) are used to insert into the protruding pin hole 216 and the post pin hole 218 and fasten the assembly. It has a fixed post 210 installation structure of the form.

그리고, 상기 끼움돌기(212)의 상면에는 작동실린더(CYL)가 고정되고, 상기 작동실린더(CYL)에는 작동로드(ROD)가 설치되어 승하강 가능하게 구성되며, 상기 작동로드(ROD)의 상단은 고정링(RIN)에 결속되고, 상기 고정링(RIN)은 상기 고정포스트(210)의 길이 일부에서 직경방향으로 관통하여 고정된다.And, an operation cylinder CYL is fixed to the upper surface of the fitting protrusion 212, and an operation rod ROD is installed in the operation cylinder CYL so as to be able to ascend and descend, and the upper end of the operation rod ROD is bound to the fixing ring RIN, and the fixing ring RIN is fixed through a part of the length of the fixing post 210 in the radial direction.

따라서, 바람이 약할 경우 작동실린더(CYL)를 상승동작시키면 고정포스트(210)가 상승하게 되는데, 이때 고정포스트(210)는 지지포스트(PST)에 끼워져 있으므로 안전하게 가이드되면서 상승하게 된다.Therefore, if the wind is weak, when the operation cylinder (CYL) is operated upward, the fixed post 210 rises. At this time, the fixed post 210 is safely guided and ascends because it is inserted into the support post PST.

이렇게 상승하게 되면 상층 기류의 영향을 받아 더욱 더 원활하고 효율적인 발전이 가능하게 된다.When it rises in this way, it is influenced by the upper air current, and more smooth and efficient power generation is possible.
