摘　　要：根据统一潮流控制器的基本原理,结合双级矩阵变换器(TSMC)的优越电气性能,提出了基于TSMC的统一潮流控制器设计方案。建立了传输线路和TSMC逆变级在dq坐标系下的标量模型,通过引入合成矢量将双输入双输出的标量模型简化成单输入单输出的合成矢量模型,应用该合成矢量模型,提出了一种具有解耦功能的三环控制策略。通过MATLAB/SIMLINK仿真表明该策略不仅能实现对潮流的解耦控制,而且具有良好的动静态性能。A design scheme of unified power flow controller based on two-stage matrix converter by virtual of the UPFC＇s fundamental principle, binding the exceptional electrical properties of TSMC, was proposed. The scalar models of transmission line and TSMC＇s inverting side were established in dq frame, the dual-input dual-output scalar models were simplified into the single-input single-output compound vector models by introducing compound vector, an three-loop control strategy which had the function of decoupling was proposed accordingly by adopting the models. It is showed by the MATLAB/SIMLINK simulation that the system not only realizes a deeoupling control of power flow but also has good dynamic and steady performances.
