파력발전시스템의 스마트 운영 및 모니터링을 위한 디지털 트윈 소프트웨어 개발

Abstract

This paper considers on the development of digital twin software to support decision making by operator and smart operation in wave energy converter system. This system have used irregular wave height variation as an input energy source. For this reason, it is necessary to predict the input energy and evaluate the system status accordingly in order to operate the installed turbine-generator safely and with high availability. In this study, digital twin technology was applied to solve this problem. Necessary data for the digital twin was identified using IDEF0 system engineering methodology. And, network system based on TCP/IP socket communication using ethernet network was built for real-time transmission of identified data. The visualization system for utilizing the transmitted data was developed using unity, a specialized 3D VR development tool. The developed digital twin software was subjected to V&V certification tests to verify its reliability.
