Abstract

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电压无功函数的协调分散控制

海上风能发电系统的整合是减少石油和天然气行业碳排放的解决方案。然而，风力发电的间歇性剖面可能会给平台的电网带来电压/频率波动的挑战。本文提出了一种协调分散控制方法，用于缓解风电系统通过长短脐带电缆连接引起的油气平台电压波动。所提出的控制分为嵌入风电系统控制中的最优损耗控制和应用于有源前端变频驱动器的改进动态无功电压函数。考虑到一个典型的巴西海上平台的真实案例试验台，风电系统为10和50MW，脐带电缆为12和150km，通过模拟结果对分散控制进行了评估。结果表明，对于三种实施的风电系统配置（即10、50和50MW/150km），动态无功电压函数在降低电压波动方面做出了有效贡献。
