摘要:
为了提升高压电力线中的高频通信信号传输质量，设计了一种用于宽带电力线通信的双向耦合器，并分析了耦合器与电力线的阻抗匹配问题。该耦合器作为收发器可用于发送和接收通信数据，结合陷波器解决了耦合器与电力线之间阻抗不匹配问题。此外，该双向耦合器能够发送或接收可供家用配电网载波频率的调制信号。建立了电力线网络测试的实验室样机进行仿真实验，实验结果表明，所提方法能够提升双向宽带传输，并且传输信号不会受到通信信道失真的影响。
Abstract:
In order to enhance the transmission of high frequency communication signals in high voltage power lines, a bidirectional coupler for broadband power line communication is designed, and the impedance matching problem between the coupler and the power line is analyzed. The coupler can be used as a transceiver to transmit and receive communication data. The impedance mismatch between the coupler and the power line is solved by combining the line notch filter. Finally, a laboratory prototype for power line network test is built and the simulation results show that the proposed method can improve the bidirectional broadband transmission, and the transmission signal will not be affected by the communication channel distortion
