As the oil and gas discovery and processing is moving towards the remote deepwater areas, the electric power delivery via long step-out to the multiple subsea processing equipment becomes more crucial. The direct current (DC) power transmission and distribution system using modular approach is considered as a competitive system architecture for subsea power delivery. This paper presents a selective operational case-study of a modular dc system, including the subsea cable modeling and its impact on the system operation. The open-circuit fault is analyzed and the protective solution is discussed as well. A scaled-down system demo was built and several selected operation conditions are tested to verify the analysis. The system modeling and study approach can be also used for other power-electronic systems and emerging applications.
