摘　　要：根据内模控制原理和解耦控制策略,研究了基于内模解耦控制的SSSC控制器,由于SSSC的d-q电流、d-q电压都存在着交叉耦合,解耦控制可以实现对d-q电流和d-q电压的成功解耦。基于内模原理设计的控制器其设计原理简单,控制器参数整定比较容易,物理概念清晰,容易实现,而且能够达到良好的效果,最后详细设计并搭建了SSSC在不同工作方式下的仿真模型,经过实验仿真验证了这种控制方法的良好性。According to internal model control theory and decoupling control strategy,the controller of static synchronous series compensator（ SSSC） is developed based on internal model decoupling control. Because both of dq currents and dq voltage exist cross coupling,decoupling control can successfully decouple dq currents and dq voltage. The design principle of the proposed controller based on internal model control is simple,the tuning of its parameters is easier and the physical concept is clear,so it can achieve good results. In the end,the simulation models of SSSC are designed in detail and established under different operating modes. This control method is verified to be very good by the simulation.
