복합 조류발전시스템의 간섭영향 고찰 (Current power marine structure interaction modeling)

초록

South Korea is surrounded by ocean with very high tidal range of up to 9.7m on the west coast with many islands on the south coast. Since there are strong current generated due to tide and narrow channels of islands, the tidal current power is known to be very parctical application. The tidal curretn power unit is composed of various elements including suppot structure, gear box, rotor, control device, convertor, inverter, power cable and etc. To generate the high electicity, many power units are required and to be installed. However, the interaction is very critical and related to the power generation. The gabs between devices can hightly affect the performance of rotor and power. Therefore, the interference of structures in axial and trnsverseal dirctions should be fully understood. In this papwer, the interactions of multi-arrayed tidal current devices are numerically and experimntally studied.
