Description

너셀 신축 이송형 해류발전기 및 해류발전기 제어 방법Control method of nucell retractable current generators and ocean current generators
본 발명은 해류발전기(Current Power Generating Device)에 관한 것으로, 수심측정을 통해 터빈로터 및 발전기를 포함하는 너셀의 적정 수심을 결정한 후 구동부의 구동에 따라 너셀이 결합된 기둥고정부를 이용하여 너셀을 상하 이동시키는 너셀 신축 이송형 해류발전기 및 해류발전기 제어 방법에 관한 것이다.The present invention relates to a Current Power Generating Device (hereinafter, referred to as " current power generating device "), which determines an appropriate depth of a nugget including a turbine rotor and a generator by measuring a depth of a nugget, And a method of controlling an ocean current generator and an ocean current generator.
일반적으로 해류발전기는 수면 아래 고정되어 설치되며, 간조 시에 터빈이 수면상에 노출되지 않도록 하기 위하여 터빈의 수중 높이를 낮게 결정하므로 만조 시에는 해수면과 터빈 사이의 거리가 멀다. Generally, an airstream generator is fixed below the water surface, and the distance between the sea surface and the turbine is high during high tide since the height of the turbine is low so that the turbine is not exposed on the water surface during low tide.
해류발전기 발전량은 유속의 3제곱에 비례하므로 최대 발전을 위해서 유속이 빠른 곳에 위치하는 것이 필수적이다. 이에 따라, 조류 유속은 해수면에서 가장 빠르며 수심이 깊어질수록 감소하므로 해수면 근처에서의 최고 유속을 이용한 터빈 발전이 필수적이다.The generation of an airstream generator is proportional to the third of the flow velocity, so it is essential that the flow is located at a fast flow rate for maximum power generation. Accordingly, the flow rate of the algae is the fastest at sea level and decreases with deeper water depth, so it is essential to develop the turbine using the highest flow rate near the sea level.
현재 해류발전기의 경우, 수면 아래 고정되어 설치되므로 수심 변화에 대응하지 못하는 구조로 최대 발전량을 구동하기 어려운 점이 있다. 단, 유지보수를 목적으로 하는 터빈 승하강 장치는 일부 존재하지만, 수심유지를 위한 승하강 개념 및 장치는 없다. 유지보수 목적의 승하강 장치는 고정 구조물이 해수면에 노출되어야 하므로 파도, 바람 등의 해양외력을 크게 받아 구조물이 대형화되어야 하고, 선박과의 충돌 위험성이 높으며 해양 공간 활용성이 떨어진다.At present, in the case of an ocean current generator, since it is fixed under the water surface, it is difficult to drive the maximum power generation amount due to the structure which can not cope with the change of the water depth. However, there are some turbine lifting and lowering devices for maintenance purposes, but there is no concept of lifting and lowering for maintaining the water depth. Since the fixed lifting and lowering device for maintenance purpose has to be exposed to the sea surface, the structure must be enlarged due to large external forces such as waves and winds, the risk of collision with the ship is high, and the utilization of the marine space is poor.

따라서 수심 변화에 따라 높이가 변하여 수면과의 일정거리 유지 가능하여 항상 해수면 근처에 터빈로터가 위치하도록 하는 해류발전기가 필요하다.Therefore, it is necessary to have an ocean current generator that maintains a certain distance from the water surface due to the change of the height according to the water depth, so that the turbine rotor is always positioned near the sea surface.

The nucell position is moved up and down to utilize the maximum flow velocity And to provide a nucelle expansion-contraction type ocean current generator and an ocean current generator control method that allow a maximum power generation amount to be derived.
