Abstract

The oscillating-water-column wave energy converter represents the complex physical characteristics associated with the water column, turbines, generator, and power converter. This study focuses on the derivation of the physical relationship between the water column and turbine based on the 1/ 4 scale model test. The aerodynamic characteristics of the OWC ducted turbine were simulated using an orifice. The turbine effect, a key element in the OWC-chamber performance evaluation, can be represented by the flow rate and pressure drop through the orifice. The turbine effect of OWC-WEC was confirmed to have a non-linear relationship from the measured flow rate and pressure drop in the model test.

진동수주형 파력발전장치는 수주, 터빈, 발전기 그리고 전력변환 장치 등이 연계된 복잡한 물리적인 특성을 나타낸다. 본 연구는 1/4 스케일의 모형시험을 통해 진동수주와 터빈의 물리적인 관계의 도출에 중점을 두고 있다. 진동수주실과 연성된 터빈의 공력특성은 오리피스를 활용하여 모사하였다. 진동수주실 성능평가에 핵심요소인 터빈효과는 오리피스를 통과하는 유속과 압력강하로 대표할 수 있다. 진동수주형 파력발전장치의 터빈효과는 모형시험에서 계측된 유속과 압력강하로부터 비선형적인 관계를 갖는 것을 확인하였다.
