海上自升式钻井平台应急配电系统的设计

The Emergency Distribution System Design on Offshore Self-Elevating Drilling Platforms

海上自升式钻井平台是一个独立的电气系统,主发电机和应急发电机给整个平台供电,应急配电系统在电气系统中应具备黑启动、应急机日常测试以及反送电的运行模式和功能,从应急配电系统的设计角度,阐述了应急发电机各种运行模式和功能,提出了应急发电机和应急配电系统在各种工况下的控制流程图,给海上自升式钻井平台应急配电系统的设计带来了很大的借鉴意义。

Offshore self-elevating drilling platform is an individual electrical system. Main and emergency generator sets provide the total platform power source. The emergency electrical system including emergency generator sets must possess the fundamental operation modes and function with blackout, routine test and feedback. The paper demonstrates the operation modes and functionalities for the emergency generator sets and illustrates the control logic is designed to fulfill the application. That will be referred to take into account in emergency electrical system design.
