진동수주형 파력발전장치의 발전기 모델을 포함한 통합유동해석 물리모델 개발

Abstract

This study was conducted to develop a real-time integrated flow analysis physics model including a generator model for an Oscillating Water Column (OWC) type wave power generator. Based on the previously performed chamber-turbine flow analysis physical model, a generator model was added to develop a physical model capable of predicting the rotational speed of the turbine. The generator physical model was implemented using the Kriging metamodel to secure real-time and obtain an interpolation model for predicting nonlinear response. The integrated flow analysis physics model was developed by integrating the flow analysis physics model within the chamber-turbine and the generator meta-model. The rotational speed of the turbine was calculated using the mechanical tote and the electrical torque of the generator model. In this study, in order to verify the integrated flow analysis physical model, the water column height in the OWC used operational data obtained from actual sensors. The air pressure in the OWC chamber and the rotational speed of the turbine obtained by using the integrated flow analysis physical model were able to obtain reasonably reasonable results for implementing a digital physical model in the future.
