摘　　要：在分析均匀传输线信道特性的基础上,引入二端口网络理论,分析低压电力线带负载信道的传输特性。采用二端口网络理论的T参数传输矩阵建立了低压电力线信道传输模型,然后利用蒙特卡洛方法建立仿真模型。模型从不同负载特性、不同接入或撤出负载变化量、不同传输信号频率对信号的影响分别进行了仿真和分析。仿真结果表明,采用二端口网络理论建立起的信道模型是可行的;采用蒙特卡洛数值模拟方法模拟低压电力线带负载信道是除了实际测试信道之外又一个可以借鉴的方法。Based on the characteristic analysis of uniform transmission channels,the transmission properties of channel of low voltage power lines are analyzed by means of two-port network theory.Using the theory of two-port network parameters transfer matrix established the low voltage power lines channel transmission model,and then using monte carlo method to establish the simulation model.Model different load characteristics,from different access or withdrawn from load variation signal transmission,different frequency to the influence of the signal are simulated and analyzed.The simulation results show that the two-port network theory to build channel model is feasible;using the method of numerical simulation of monte carlo simulation with low voltage electric load is in addition to practical test channel,and channel a referential method.
