Offshore wind is a rapidly growing renewable energy resource. Harvesting offshore energy requires multimegawatt wind turbines and high efficiency, high power density, and reliable power conversion systems to achieve a competitive levelized cost of electricity. An integrated system utilizing one active and multiple passive rectifiers with a multiport permanent magnet synchronous generator is a promising alternative for an electromechanical power conversion system. Deployment of the integrated systems in offshore wind energy requires maximum power point tracking (MPPT) capability, which is challenging due to the presence of numerous uncontrolled passive rectifiers. This article shows feasibility of MPPT based on a finding that the active-rectifier $d$-axis current can control the total system output power. The MPPT capability opens up opportunities for the integrated systems in offshore wind applications.

使用集成发电机-整流器系统的风力涡轮机最大功率点跟踪

海上风电是一种快速增长的可再生能源。收集海上能源需要数兆瓦的风力涡轮机和高效率、高功率密度和可靠的电力转换系统，以实现具有竞争力的平准化电力成本。利用一个有源和多个无源整流器与多端口永磁同步发电机的集成系统是机电功率转换系统的一种有前途的替代方案。在海上风能中部署集成系统需要最大功率点跟踪 (MPPT) 能力，由于存在大量不受控制的无源整流器，这具有挑战性。本文基于有源整流器 $d$-axis 电流可以控制总系统输出功率的发现，展示了 MPPT 的可行性。
