摘　　要：为了研究无功补偿器对电力线通信的影响,提出一种建立无功补偿器端口网络高频模型的方法,利用该方法建立的无功补偿器高频模型可用于进一步的理论分析计算和系统仿真,方便分析无功补偿器对电力线通信信道阻抗、噪声、衰减等方面的影响。本方法把无功补偿器的每一相等效成一个无源一端口网络,通过实验测量无功补偿器在不同频率下的阻抗幅度与阻抗角,借助1st Opt对测量数据进行拟合,得出网络的阻抗函数,从而建立无功补偿器的高频模型。此方法避免了复杂的理论分析推导,模型计算值与测量值比较吻合,说明建立的无功补偿器高频模型是有效合理的。In order to easily analyze the influences of reactive power compensation on power line communication,this paper proposes a high frequency modular port model by reactive power compensator modeling method. The model can be put into the power line communication simulation system,and then the influences of reactive power compensation on impedance,noise and signal attenuation of power line communication channel can be analyzed. Each phase of the reactive power compensator is transformed into a passive one-port network. The impedance of the reactive power compensator in the high frequency is measured,including its amplitude and angle,and then the test data are fit through1 st Opt to get the network impedance. The calculation results by using the model fit well with the test data and then the validation of the model is proved. The method is convenient and efficient.
