ECS 신뢰도 확보를 위한 함정 추진체계용 시뮬레이터 개발

Abstract

In the past, diesel engines, steam turbines or gas turbines were the typical mechanical propulsion system that was used on the warship. Therefore, the power train was simple and it was easy to repair and integrate into a system.

However, due to recent awareness of survival performance and automation, propulsion system of warships is evolving to hybrid mechanical -electrical propulsion system. As a result, the requirements of the propulsion control system have became more complicated, and warships ECS(Engineering Control System) have gained more attention.

During the operation of the ship, controlling the propulsion system is getting more complicated. And this is one of the most important factor to consider to while maintaining or rapidly changing the speed of the warship.

Since this ECS is manufactured only from foreign companies (L-3 Mapps, SEASTEMA), localizing its technology has became important. And ensuring the reliability by using the simulator is the critical factor of localization.

This paper is a study of warship propulsion system simulator design. In order to develop this simulator, the procedure is based on four main steps.

First, in order to collect core technologies and informations, a case study is carried out by internet and conference papers focusing on SEASTEMA and University of Genoa. Second, to develop the simulator, virtual warship propulsion system such as defining equipment specifications has been defined based on real operating data from the warship propulsion system. Then, RT-HIL(Real Time Hardware In the Loops) simulator was developed by LabVIEW and PXI. And it contains 4 sub-models

Basic model, logic model, etc model, communication model.

Finally, scenarios have been developed based on the warship's critical conditions and ECS will be verified by RT-HIL simulator.
