海洋石油平台电力组网的设计与实现

Design and practice of power grid for offshore oil platforms

介绍了南海某油田海洋石油平台电力组网及其能量管理系统(EMS)的设计。针对海上石油平台电网的特点,设计中解决了小电网励磁涌流问题以及长距离海缆充电功率较大等问题;同时提出了集电网数据采集和安全监视(SCADA)、在线安控及电站综合自动化等功能为一体的EMS系统建设方案,解决了小电网的安全稳定控制问题。组网的实施增加了供电可靠性、减少了发电机组备用容量,节省投资、具有推广价值。

This paper introduces a design of power grid and EMS system for offshore oil platforms in South ChinaSea. According to the characteristics of the power grids on offshore oil platforms, the design can solve the inrush current of transformer and the large charging power in long submarine cable line, etc. Meanwhile, it also puts forward an integrated EMS system project of SCADA,online safe control and integrated automation system for the power station,which can settle the safety and stability control issues. The power grid can improve the power supply reliability,reduce the spare capacity of the investment and have great value to popularization.
