摘　　要：分布式串联补偿装置通过变压器原理,将串联电抗耦合到初级回路,通过改变次级的电抗值实现串联补偿的功能。主变压器作为装置最主要的功率转换器件,其功率输出特性将直接决定整个装置的功率密度和发热问题。将装置主变压器输入视为恒流源,建立了主变压器的功率输出模型,分别研究得到主变压器的输出功率与负载电容、线圈匝数及负荷电流的对应关系,最后通过实验验证了上述结论的正确性。Distributed series compensation device makes the series reactor coupled to the primary circuit through the transformer principle.It changes the reactance which is in series into the primary circuit by changing the reactance of the secondary side,which aims to achieve the function of series compensation.As main power conversion part of the device, the power output characteristics of the main transformer will directly determine the power density and heat problems of the whole device.The main transformer is considered as a constant current source, a power output model of the main transformer according to the law of electromagnetic induction is established.The relationships between the output power of the main transformer and the load capacitance, the number of turns and the line current are studied. Finally, the validity of the above conclusion is verified by experiments.
