摘　　要：为了深入研究分布式潮流控制器对系统功率控制的特性,得出分布式潮流控制器的串并联等效模型,给出分布式潮流控制器的控制系统。采用分布式静止无功补偿器单相等效电压源建模的方法对分布式功率潮流控制器的基波和三次谐波分别建立了系统模型,并建立了串并联变流器交换的三次谐波有功功率与直流电容的数学模型。基于该等效模型,推导了分布式潮流控制器的最大功率调控范围,设计了以串联侧基波电压为控制变量、线路有功无功为控制目标的串联侧基波控制器,得出了以三次谐波电压为控制变量、直流电压为控制目标的控制器。静动态仿真研究表明,所提出的分布式潮流控制器的数学模型和控制系统是正确的,为分布式潮流控制器的进一步研究提供了理论依据。For the sake of researching the power control ability of the distributed power flow controller, we obtain the series-parallel equivalent model and present the control systems of the distributed power flow controller. The method of distributed static series compensator single phase equivalent voltage source modeling is adopted to construct the mathematic model of the distributed power flow controller, both for the fundamental harmonic and the triple frequency harmonic. The mathematic model of the DC capacitor and the triple frequency harmonic active power exchanged between the shunt and the series converter is established. The regulation scale of the maximum power of the distributed power flow controller is deduced. The series side controller is designed with the control variable of series side fundamental harmonic voltage and the control target of active or reactive circuit, and then a controller is designed with the triple frequency harmonic voltage as control variable, and the DC voltage as the control target. The dynamic and static simulation results verify the correctness of the mathematic model and the control system. This will be useful for the future research of the distributed power flow controller.
