Description

Multi-stage hydro power plant {AAAAA}

본 발명은 잉여용수를 활용하여 전력을 증산하고, 수위조절작업이 불필요한 다단계 수력발전장치에 관한 것이다.The present invention relates to a multi-stage hydroelectric power generation apparatus that increases power by using surplus water and does not require level control.

통상의 수력발전은 댐당 발전소는 한 곳뿐이며, 저수량이 많고 적음에 관계없이 전력수요에 따라 발전량을 조절하게 된다.In general, there is only one power plant per dam, and the amount of power is controlled according to electric power demand regardless of whether there is a lot of water or is low.

발전댐은 장마철이나 집중호우와 같이 강수량이 많은 시기에는 홍수피해의 예방차원에서 상류로부터 흘러들 유입수를 예상하고 저수량을 줄이는 수위조절작업에 돌입하고 긴장을 늦추지 않게 된다.In case of heavy rainfall such as rainy season or heavy rain, the power generation dam is expected to inflow from the upstream to prevent flood damage and to reduce the level of water and reduce the tension.

만약 강우량에 대한 예보가 빗나간 경우에는 공연히 물만 허비한 꼴이 되고말 것이다. 또, 예상치 못한 강우로 댐의 수위가 만수위에 이르면 위험천만이며 당황하지 않을 수 없다. 긴급히 수문을 열어서 수위를 낮춰야 한다.If the forecast for rainfall falls off, it will run out of water. In addition, when the water level of the dam reaches the full water level due to unexpected rainfall, it is dangerous and embarrassing. Urgently open the gate to lower the water level.

그러나 수위조절에도 불구하고 수위가 계속 오른다면 이는 여간 큰일이 아닐수 없다.But if the water level keeps rising despite the water level adjustment, this is a big deal.

발전과 관계없이 흘려버리는 그 많은 물을 에너지화할수만 있다면 경제적으로 큰 이득일 것이다.It would be a great economic benefit if we could energize that much water that flows away from power generation.

본 발명은 상기와 같은 수위조절용 물을 발전에 이용하여 전력생산량을 늘리고 수위조절작업이 불필요한 수력발전장치를 제공하려는 것이다.The present invention is to provide a hydroelectric power generation apparatus using the water for the water level control as described above to increase power production and no water level adjustment work.

본 발명에서 제안하는 수력발전장치는 댐의 만수위까지의 전체 저수높이를 3등분하고 그 2/3되는 지점에 터널수로 등의 도수로를 건설하고, 그 도수로로부터 발전에 필요한 낙차만큼 떨어진 인접 골짜기에 제1 보조발전소를 건설하며, 이 보조발전소의 퇴수로로부터 또다시 발전에 필요한 낙차만큼 낮은 곳에 제2 보조발전소를 건설하고, 제2 보조발전소의 퇴수로는 기설 발전소의 댐 아래 보조댐에 이르도록 운하를 파서 저수량을 보충토록 함으로써 가뭄,홍수에 대비한 수위조절용 물로 발전량을 늘릴 수 있는 다단계 수력잘전장치를 제안한다.The hydroelectric generator proposed in the present invention divides the total reservoir height up to the full water level of the dam into three and constructs a channel such as a tunnel channel at a point two-thirds of the dam, and is located in an adjacent valley separated by the drop required for power generation. The first auxiliary power plant is constructed, and the second auxiliary power plant is constructed from the drainage of the auxiliary power plant as low as the drop required for power generation, and the drainage path of the second auxiliary power plant reaches the auxiliary dam under the dam of the existing power plant. It is proposed a multi-stage hydropower device that can increase the amount of power generated by the water level control water in preparation for drought and flood by digging up the reservoir.

도 1은 본 발명에 의한 수력발전장치의 개념도이다.1 is a conceptual diagram of a hydroelectric generator according to the present invention.

〈도면의 주요 부분에 대한 부호의 설명〉<Explanation of symbols for main parts of drawing>

1 : 발전소 2 : 발전댐1: power plant 2: power generation dam

3 : 도수로 4 : 제1 보조발전소3: raceway 4: first auxiliary power plant

5 : 제2 보조발전소 6 : 보조댐5: secondary auxiliary power plant 6: secondary dam

7 : 운하7: canal

도 1에서, 퇴수로에 발전소(1)가 설치된 발전댐(2)에 있어서, 이 발전댐(2)의 만수위까지의 전체 저수높이를 편의상 3등분한다. 이는 년중 평균강수량을 기준으로 했을 때 발전댐(2)의 적정수위가 만수위의 대략 2/3 수위라고하는 산출근거를 바탕으로 한 것이다.In FIG. 1, in the power generation dam 2 in which the power plant 1 was installed in the discharge path, the total reservoir height up to the full water level of this power generation dam 2 is divided into three for convenience. This is based on the calculation basis that the proper level of the dam 2 is about 2/3 of the full level, based on the average amount of precipitation during the year.

이렇게 3등분한 저수높이중 2/3 지점에 터널수로 등의 도수로(3)를 건설한다. 이 도수로(3)는 발전댐(2)에 인접한 골짜기로서 낙차가 크면 더욱 좋다.A waterway (3) such as a tunnel waterway is constructed at two-thirds of the heights divided into three. This raceway 3 is a valley adjacent to the power generation dam 2, and it is better if the drop is large.

상기 도수로(3)로부터 발전에 필요한 낙차에 상응하는 만큼 낮은 골짜기에 제1 보조발전소(4)를 건설한다.The first auxiliary power plant 4 is constructed in a valley as low as that corresponding to the drop required for power generation from the raceway 3.

그리고 상기 제1 보조발전소(4)의 퇴수로에서 또다시 발전에 필요한 낙차만큼 낮은 곳에 제2 보조발전소(5)를 건설한다.In addition, the second auxiliary power plant 5 is constructed at a lower level than the drop required for power generation again in the discharge path of the first auxiliary power plant 4.

발전댐(2)의 하류에는 보조댐(6)을 건설하고, 제2 보조발전소(5)의 퇴수로와는 운하(7)로 연결한다.Downstream of the power generation dam 2, an auxiliary dam 6 is constructed, and the canal 7 is connected to the discharge path of the second auxiliary power plant 5.

발전댐(2)의 적정수위를 넘는 물은 폭우, 집중호우, 홍수시에는 방류로써 흘려버리게 되지만 적정수위 이상의 용수는 도수로(3)를 통하여 바이패스되어 제1 보조발전소(4)로 유출되고, 여기서 전력이 증산된다.Water exceeding the proper level of the power generation dam (2) is discharged by the discharge during heavy rains, heavy rains, and floods, but water above the proper level is bypassed through the waterway (3) and flows out to the first auxiliary power plant (4), Here the power is multiplied.

따라서 발전댐의 수위를 낮추기 위한 방류작업은 따로 필요치 않다. 도수로(3)로 흘러나가는 만큼 저절로 수위가 조절되기 때문이다.Therefore, no discharge is required to lower the level of the dam. This is because the water level is adjusted by itself as it flows into the raceway (3).

1차 보조발전소(4)를 거치는 동안 전력생산에 쓰인 물은 제2 보조발전소(5)로 유입되어 또다시 전력을 생산하게 된다. 두 차례에 걸친 보조발전을 통하여 얻어지는 전력은 막대하다.Water used for power generation while passing through the primary auxiliary power plant 4 is introduced into the second auxiliary power plant 5 to produce electricity again. The power obtained from two secondary generations is enormous.

2차 보조발전에 쓰인 물도 그냥 방류하는 것이 아니라 운하(7)를 통하여 발전댐(2)의 하류에 새로 건설한 보조댐(6)으로 일단 흘려보냈다가 그래도 넘치는 양은 계곡으로 흘려보내고 머무는 물은 심야시간대의 잉여전력을 이용하여 발전댐(2)으로 양수했다가 전력수요가 많은 시간의 발전용수로 재활용한다.Instead of just discharging the water used for the secondary auxiliary power generation, the water flowed through the canal (7) to the newly constructed auxiliary dam (6) downstream of the power generation dam (2). It pumps to the power generation dam (2) by using surplus power and recycles it to the power generation water of high demand.

이상 설명한 바와 같은 본 발명의 다단계 수력발전장치는 사실상 전력생산과는 무관한 적정수위 이상의 잉여용수를 방류하지 않고 기존 발전소의 발전용수와는 달리 적어도 하나 이상의 보조발전소용 용수로 전환시켜 전력생산을 늘릴 수 있으므로 전력증산에 이로울 뿐만아니라 가뭄,홍수,폭우,호우에 대비한 발전댐의 수위조절작업을 생략할 수 있는 장점이 제공되고, 잉영용수의 이용극대화에 이바지하는 바 크다.As described above, the multi-stage hydroelectric generator of the present invention can increase power production by converting water into at least one auxiliary power plant unlike the power generation water of the existing power plant without discharging excess water above a suitable level, which is actually irrelevant to power generation. Therefore, it is not only beneficial to increase power, but also provides the advantage of eliminating the water level control of the dam in preparation for drought, flood, heavy rain, and heavy rain, and contributing to maximizing the use of surplus water.
