电力线通信中传输线参数测试与应用
Measurement and Application of Electrical Parameters in Power Line Communication
In order to analyze the characteristics of PLC channel,it is necessary to research the electrical parameters of transmission lines by actual testing.Based on coupling transmission line theory,a specific length of power line is tested by simulating the real line distribution,and the electrical parameters at different frequencies are introduced.In comparison with the test value of the simulation results,the accuracy of theoretic calculation is verified.Besides,we establish the model of various branch lines of power communication network based the transmission line model.The results of Pspice simulation are in consistent with the actual tests,which provides a useful theoretical basis for the establishment of PLC network and the analysis of channel characteristics.
