实现多端高压直流（HVDC）输电系统需要解决的主要问题之一是缺乏实用的潮流控制方法。行业领导者和研究人员提出了一些基于换流站控制或新电力电子设备与电网连接的潮流控制方法。本研究提出了一种适用于多端高压直流输电系统的三端口绝缘栅双极晶体管电流控制（CFC）装置的操作和控制。所提出的控制器的主要特点和功能，包括电缆电流的平衡，限制电缆电流和电流归零的幅度进行了演示。利用电力系统计算机辅助设计（PSCAD）/电磁暂态与直流（EMTDC）网络仿真软件对三端口CFC进行仿真，评估其稳态和动态性能。此外，低功耗原型实现的两个和三个端口的CFC实验验证其不同的功能。仿真和实验研究探讨了快速的动态响应和结果表明，CFC研究可能有显着的作用，在多端高压直流系统的潮流控制。
One of the main problems that need to be solved to allow the realisation of multi-terminal high-voltage direct current (HVDC) transmission systems is the absence of a practical power flow control method. Industry leaders and researchers have proposed a few methods of power flow control based on either the control of converter station or the connection of new power electronic equipment to the grid. This study presents the operation and control of a three-port insulated gate bipolar transistor-based current flow control (CFC) device suitable for multi-terminal HVDC systems. Key features and functionalities of the proposed controller including the balancing of cable currents, limiting the magnitude of cable current and current nulling are demonstrated. The three-port CFC was simulated using power system computer aided design (PSCAD)/electromagnetic transient and direct current (EMTDC), network simulation software to evaluate its steady state and dynamic performance. Furthermore, low-power prototypes are implemented for a two and three-ports CFC to experimentally validate their different functionalities. Simulation and experimental studies explore the fast dynamic response and the results show that the CFC studied may have a significant role to play in the control of power flows in multi-terminal high-voltage DC systems.
