摘　　要：由分布式潮流控制器的特性出发,建立了反映内部3次谐波能量动态交换的基于电流注入法和功率解耦控制法的分布式潮流控制器等效数学模型,设计了以3次谐波能量平衡为基础的串并联控制器。基于电力系统全数字仿真装置(ADPSS)的电磁暂态仿真功能和用户自定义模型功能,分别建立了分布式潮流控制器的仿真平台;基于该电磁暂态实验平台,通过分布式潮流控制器等效模型与电磁暂态模型仿真结果的对比分析,验证了所建分布式潮流控制器等效数学模型的正确性;基于机电暂态中用户自定义模型功能,在WSCC9系统和某500kV实际电网进行了稳态功率调控实验,证明了所建模型的有效性。Based on the characteristics of the distributed power flow controller, the established equivalent mathematical model reflects the inner 3rd harmonic power, which relies on the current injection and the power decoupling control. Series and shunt controllers with the fundamental of the 3rd harmonic power balance are designed. With the help of electromagnetic transient simulation function and user definition model function in advanced digital power system simulator （ADPSS）, the simulation platforms are respectively established for distributed power flow controller. Based on the electromagnetic transient experimental platform, the simulation results are compared between the equivalent model and the electromagnetic transient model, which verifies the correctness of the equivalent mathematical model of the distributed power flow controller. Finally, based on the user definition function in electromechanical transient model, the validity of the model is proved by the steady state power control experiments in the standard WSCC9 system and some 500 kV power grid system.
