The integration of offshore wind energy power system is a solution to reduce carbon emissions in the oil and gas sector. However, the intermittent profile of wind power generation can bring challenges of voltage/frequency fluctuations to the electrical grid of the platform. This article proposes a coordinated decentralized control used to mitigate voltage fluctuation in oil and gas platform caused by connection of wind power system through short- and long-umbilical cables. The proposed control is split into optimum loss control embedded in the wind power system control, and modified dynamic volt-var functions applied to active front-end variable frequency drives. The decentralized control is evaluated by means of simulation results considering a real case test bench of a typical Brazilian offshore platform with a wind power system of 10 and 50 MW, and umbilical cable of 12 and 150 km. The results indicate an effective contribution of the dynamic volt-var function in reducing voltage fluctuations for the three implemented wind power system configurations (i.e., 10; 50, and 50 MW/150 km).

风力发电油气平台动态伏无功函数的协调分散控制

海上风能电力系统一体化是油气行业减少碳排放的解决方案。然而，风力发电的间歇性会给平台电网带来电压/频率波动的挑战。本文提出了一种协调分散控制方法，用于缓解由于风电系统通过短脐带电缆和长脐带电缆连接而引起的油气平台电压波动。所提出的控制分为嵌入风力发电系统控制中的最佳损耗控制和应用于主动前端变频驱动器的改进的动态伏特-无功函数。考虑到具有 10 和 50 MW 风力发电系统的典型巴西海上平台的真实案例测试台，通过仿真结果评估分散控制，以及12公里和150公里的脐带缆。结果表明，动态伏特-无功函数对减少三种实施的风力发电系统配置（即10、50 和50 MW/150 km）的电压波动做出了有效贡献。
