초록

전전기 함정용 통합전력시스템은 AC-전력계통인 경우는 4.16 kV 이하의 계통전압을 적용하는 통합전력시스템에서 13.8 kV_AC으로, 그리고 DC_전력계통인 경우는 12 KV_DC으로 고압화되는 추세로 진화하고 있다. 이런 배경에서 본 논문에서는 중전압 전력계통에서 사용할 수 있는 모듈러 멀티레벨 컨버터를 소개하고, 제어방법과 적용사례 결과를 제시하였다.

Abstract

The integrated power system for all-electric ships is evolving toward a high voltage of 13.8 kV_AC in the integrated power system that applies a grid voltage of 4.16 kV or less in the case of an AC-power system, and 12 kV_DC in the case of a DC-power system. Against this background, in this paper, a modular multi-level converter that can be used in medium voltage power systems is introduced, and the control method and application case results are presented.
