摘　　要：基于奇异摄动理论设计多馈入高压直流输电系统的附加控制器,把电力系统整体优化问题分解为子问题,深入到系统动态的本质,分解后所得到的快系统和慢系统是分离的,相应的子问题也是相互独立的,既不存在协调问题,也不存在协调迭代问题,达到了简化运算的目的.仿真实验结果表明,该控制策略能够较好地提高交直流互联系统的暂态稳定性.Based on the singular perturbation theory, a multi-infeed HVDC system auxiliary controller was designed, the overall power system optimization problem was decomposed into sub problems. Being insighted into the dynamic nature, the fast decomposition system and the slow system were separated, the corresponding problem was independent of each other, neither the presence of coordination problems, nor the coordination problem of iterative, and the objective of simplifying operation was realized. The simulation results were shown that the control strategy could improve the transient stability of AC/DC interconnected system.
