摘　　要：对目前性能最为先进的第6代半潜钻井平台配电系统进行了研究与开发。该配电系统主电源来自于8台型号相同的大功率柴油发电机,应急电源来自于应急柴油发电机。每2台柴油机发出的11 kV高压电组成1个配电盘,系统的4个配电盘通过跨接断路器可组成环形供电网络,8台推进器通过其专用变压器和变频器实现动力定位功能;钻井VFD系统采用12脉整流的直流公共母线方式,整流器容量按一备一用的方式进行配置,逆变器与驱动对象采用一对一控制方式,钻井MCC由380 V配电盘和220 V配电盘组成。系统通过合理备份和冗余提高了平台设备的可靠性。The introduction was made for the study of power distribution system for 6th generation deepwater drilling semi-submersible,which is the most advanced semi-submersible now.The main power of the power distribution system was produced by the eight sets of the same model diesel generators and the emergent power was produced by an emergent diesel generator.Four switchboards that were consisted of two output of the diesel generators could buildup a ring power distribution system by the breakers that were set on the side of the every switchboard.The dynamic position function was achieved by the eight propulsion thrusters that were controlled by the special transformers and transducers.The VFD of drilling system adopted the DC common bus technology and the DC voltage was engendered by the 12-pulse rectifiers whose capabilities fulfill the back-up principle.Every electromotor of equipment was driven by a special motor module.The drilling MCC consisted of 380V switchboard and 220V switchboard.It could improve the equipment reliability by the reasonable redundancy.
