    摘要: 基于变流技术的柔性直流输电(VSC-HVDC)系统具有小型、高效、控制灵活等特点,已成为当前输配电领域的研究热点之一。本文阐述了柔性直流输电系统的结构及其功能,建立了d-q旋转坐标系下精确的VSC-HVDC数学模型,提出了柔性直流输电系统的直接电流控制方法,并针对柔性直流输电系统的特点,构建了不同的控制模式及其组合。仿真结果表明,所提出的控制方法结构简单,具有良好的动静态性能,成功实现了有功功率和无功功率的独立控制。 VSC-HVDC technology has small, efficient and flexible control characteristics and has become a hot spot gradually in transmit and distribute of electric power. The basis of the composition of the VSC-HVDC system structure and function are described, and established the precise mathematical model of VSC-HVDC under the dq rotating coor- dinate system, then proposed a direct current control strategy of the VSC-HVDC system, and built some different con- trol models and combinations which aim to the characteristics of the VSC-HVDC system. At last, the results of simula- tion shows that the proposed control strategy has a simple structure, excellent dynamic and stationary performance and successfully achieved the active and reactive power control independently.
