Abstract

In recent years, the importance of environmental regulations is increasing in the shipping industry, and the demands of the industry for this are rapidly increasing. Accordingly, the demand of ship owners is increasing as the shaft generator is a technology that responds to environmental regulations that can be applied to ships the fastest. The shaft generator is a device that can increase the fuel consumption rate of the main propulsion engine by installing an electric motor in the main propulsion engine and using it variably according to the load environment. It operates by the power of the motor at low speeds, and when a sudden load is required, the main propulsion engine and motor operate together, enabling efficient operation. In this paper, the diesel engine and shaft generator of a tug boat are modeled using MATLAB Simulink, and the fuel consumption rate is verified through simulation.

최근 해운산업에서는 환경규제에 대한 중요성이 높아지고 있으며, 이를 위한 산업의 요구가 급격히 높아지고 있다. 이에 샤프트제너레이터는 선박에 가장 빠르게 적용이 가능한 환경규제 대응기술로 선주의 요구가 증가하고 있다. 샤프트제너레이터는 메인추진엔진에 전동기를 설치하여, 부하환경에 따라 가변적으로 사용함으로 메인추진엔진의 연료소모율을 줄일 수 있는 장치이다. 저속에서는 모터의 힘으로 동작하고, 급격한 부하가 필요할 때에는 메인추진엔진과 모터가 함께 동작함으로 효율적인 운전이 가능하다. 본 논문에서는 MATLAB Simulink를 이용하여 터그보트의 디젤엔진과 샤프트제너레이터를 모델링하고, 시뮬레이션을 통해서 연료소모율을 검증하였다.
