The west and south coastal regions of Korea are known to be of strong tidal current speed. With the increasing demand for renewable energies, the resource assessment has been a crucial issue which should be conducted before any detail planning and development of the potential sites for tidal current farm. Although there are several results of resource assessment of tidal current energy in Korea, the resource assessment method is not officially announced. This undefined methodology makes the results unreliable and useless. Recently new renewable energy potential definition has been announced by KIER (Korea Institute of Energy Research). This categorizes energy potential as four steps; theoretical, geographical, technical and market potentials. This paper describes the resource assessment of tidal current power in Korea based on API (Averaged Power Intercepted). The results show that the Incheon-Gyeonggi and Jeollanam-do are very promising areas for tidal current power in Korea.

This paper describes the methodology and results of a tidal current resource assessment in Korea based on the mean surface velocities from tidal current observations and numerical simulations. The tidal current observation data from 1,938 measuring points was provided by the KHOA (Korea Hydrographic and Oceanographic Agency). A numerical simulation of ocean flow circulation in Korea was conducted to explore the detailed distribution of tidal currents in Incheon-Gyeonggi and Jeollanam-do where there are very high tidal energy potentials and suitable sites for tidal energy farm development. The theoretical tidal current potential was calculated using the API (Averaged Power Intercepted) method which is generally applied in wind power potential estimation in Korea. A numerical simulation of the flow circulation through narrow passages between the islands is very important for resource assessment study.

조류발전이 해양동물에 미치는 영향 검토 (리뷰)

박정연(Jeong Yeon Park),박영철(Young Cheol Park) 한국습지학회 2024 한국습지학회지 Vol.26 No.2

조류발전은 조석 현상에 의해 발생하는 조류를 이용하여 에너지를 생산하는 발전 방식이다. 조석 현상은 지구가 존재하는 한 발생하는 자연적인 현상으로 조류발전을 통하여 지속가능하고, 규칙적인 에너지 생산이 가능하다. 이에 많은 국가에서 조류에너지 개발에 노력을 기울이고 있는 실정이나, 조류발전이 해양 동물에 미치는 영향에 대한 우려도 여전히 존재하고 있다. 이에 본 논문에서는 조류발전이 해양동물에 미치는 다양한 영향을 종합적으로 검토하고, 향후 추진해야 하는 과제들에 대하여 고찰하였다. Tidal current power generation is a power generation method that produces energy using tidal currents generated by tidal phenomena. Tidal current power generation is a sustainable and regular energy production because tidal phenomenon occurs as long as the earth exists. Many countries are focusing on the development of tidal energy, but there are still concerns about the impact of tidal energy on the marine animals. In the present study, we reviewed on the various impacts of tidal power generation on marine animals and the future assignments.

Due to the global warming, the need to secure the alternative resources has become more important worldwide. Having very strong current on the west coast with up to 10 m tidal range, there are many suitable sites for the application of TCP(Tidal current power) in Korea. Not only from the current produced from the high tidal range, but also it can be widely applied to the offshore jetties and piers. The VAT(Vertical axis turbine) system could be very effective tidal device to extract the energies from the attacking flow to the structures. For the relatively slow current speed, the VAT system could be more effective application than HAT(Horizontal axis turbine) device. The performance of VAT can be evaluated by various parameters including number of blades, shape, sectional size, diameters and etc. The paper introduces the multi-layer vertical axis tidal current power system with savonius turbine. The turbine was designed with consideration of optimal blade numbers and the performance was simulated by CFD analysis.

Hyundai Heavy Industries has developed a tidal current energy converter utilizing the accumulated technology as the world largest constructor for ship and offshore structures. The model has two sets of turbines in both ends in order to utilize the bi-directional current flows in flood and ebb tide. The torque produced by turbine in tidal current is directly delivered to generator along the horizontal axis, in which the turbine, gear, generator, gear and turbine are connected successively. The manufactured model for field test has the turbine diameter of 5 meters to produce the maximum power of 500kW at maximum current speed of 5m/s. The technical verification of tidal power converter was performed by means of small scale model test in towing tank as well as field test at the Strait of Uldolmok located in Jindo of Jeollanamdo province. Field test was performed by mounting the tidal current converter on the SEP(Self Elevating Platform) which could lower the 4 vertical legs on the seabed and could elevate platform over the water surface using the hydraulic power for itself. The field test performed for a month shows that power output is similar or larger compared with the expected one in design stage. This paper presents the development of tidal current energy converter and real sea field test by Hyundai Heavy Industries. This project has finished successfully and provided the technical advance toward commercial services for tidal current power generation in the south-west region in Korea.

The Wake Characteristics of Tidal Current Power Turbine

Due to global warming, the need to secure an alternative resource has become more important nationally. Due to the high tidal range of up to 9.7m on the west coast of Korea, numerous tidal current projects are being planned and constructed. To extract a significant quantity of power, a tidal current farm with a multi-arrangement is necessary in the ocean. The rotor, which initially converts the energy, is a very important component because it affects the efficiency of the entire system, and its performance is determined by various design variables. The power generation is strongly dependent on the size of the rotor and the incoming flow velocity. However, the interactions between devices also contribute significantly to the total power capacity. Therefore, rotor performance considering the interaction problems needs to be investigated for generating maximum power in a specific field. This paper documents the characteristics of wake induced by horizontal axis tidal current power turbine.
