Low-frequency Offshore Wind Power Transmission System With Dual-end Grid-forming Control
近年来,海上风电越来越受到人们的关注。在海上风电送出的应用场景中,低频交流(low-frequency alternating current,LFAC)输电是一种在中远海具有较大优势的新型输电技术。为了提高海上风电系统的支撑能力,可以在换流站两侧均采用构网型控制。该文介绍了基于双端构网型控制的海上风电低频传输系统的基本结构和控制方法;此外,利用功率备用控制使风电场能够参与一次频率调节,提高电力系统稳定性;最后,通过实时数字仿真(real time digital simulation,RTDS)系统验证了所设计控制系统的有效性。
Abstract
The offshore wind power has been gaining increasing attention in recent years. Low-frequency alternating current (LFAC) transmission is emerging as a promising technology with specific advantages for offshore wind power transmission. In order to enhance the support for the power system
grid-forming control can be implemented on both sides of the converter station used in LFAC. This paper introduces the structure and control of the LFAC offshore wind power transmission system with dual-end grid-forming control. Furthermore
this study utilizes power reserve control to enable wind farms to participate in primary frequency regulation. Finally
the effectiveness of the designed control system is verified through real time digital simulation (RTDS).
