中海油在渤海、东海、南海海域已经有几十个模块钻机和修井机在使用,而且随着中国海洋石油的快速发展,海上油田将越来越多,而对于海上石油平台供电系统的安全稳定性的要求也在日益增高。当电力系统发生故障时,及时有效的切除故障元件、支路无疑是保证电力系统安全的最有效方法之一,为保证海洋平台电力系统安全稳定运行,保证电能质量、防止故障的扩大和事故的发生,继电保护是必不可少的组成部分。
CNOOC has used dozens of modular drilling rigs and workover rigs in the Bohai Sea, the East China Sea and the South China Sea. With the rapid development of China’s offshore oil, offshore oil fields will be more and more, but for the safety and stability of the offshore oil platform power supply system Sexual requirements are also on the rise. When the power system failure, the timely and effective removal of faulty components, branch is undoubtedly one of the most effective ways to ensure the safety of the power system. In order to ensure the safe and stable operation of the power system of the offshore platform, ensure the power quality, prevent the expansion of the fault and the accident Occurs, relay protection is an integral part.
