추진시스템 검증을 위한 추진시스템 장비 모델 및 시뮬레이터 개발

Abstract

With the development of the power conversion industry and technology, a hybrid propulsion system using a propulsion motor such as CODLOG (COmbined Diesel-eLectric Or Gas turbine), CODLAD (COmbined Diesel-eLectric And Diesel) has been applied to recently warship. Compared to mechanical propulsion system, these Hybrid propulsion system has advantages such as anti-submarine ability, viability and energy efficiency. However, the hybrid propulsion system is complicated in design and production, and as the number of interlocked devices increases, there are many problems that may occur in the interlocking process, And verification of the propulsion system and countermeasures are necessary. These hybrid propulsion system must be equipped with reliable the ECS (Engineering Control System) for stable battleship operation. An ECS is a very important equipment for battleship operation, and it controls and monitors the propulsion system. Therefore, reliability is the most important thing for the ECS. For this reason, the ECS of a warship equipped with a hybrid propulsion system depends on foreign professional companies such as L3, SEASTEMA. In this research, we intend to develop herein a RT-HIL (Real-Time Hardware In the Loop) simulator that validates the ECS using NI’s cRIO and LabVIEW. Theses model was developed based of system identification technique for four types of equipment: gas turbine, propulsion motor, reduction gear and Controllable. The developed simulator was designed based on the CODLOG propulsion system and compared and analyzed the actual equipment data with the developed simulator data As a result of the simulation, the error between the actual data of the gas turbine and the electric propulsion motor and the model has an error within 5%. This simulation can be used for validation and performance verification before the construction phase of the combined – type propulsion system in the future.
