Research on Time Slot Multi-channel Impedance Measurement Method for Power Communication System

针对电力通信系统通道阻抗太大,存在不能及时合理分配电能,导致电能分配不均匀的问题,为此提出一种电力通信系统时隙式多通道阻抗测量方法,利用主、备方式提升电力系统的可靠性,防止通信信号传输时受到干扰,再通过优先级与通道间的连通方式,构建时隙式系统模型,分析时隙系统通道的优先级吞吐性,通过多通道端口的有源抗测量系统,收集单元相控阵数据,最后分别测量有源端口的参数、阵内单元的互偶以及阵内单元端口的驻波,得出多通道阻抗测量值。实验证明:所提方法可靠性良好,精度较高且拥有较强直观性。

In view of the problem that the channel impedance of the power communication system is too large and the electric energy cannot be distributed reasonably in time, which leads to the uneven distribution of electric energy, therefore, a multi-channel impedance measurement method based on time slot in power communication system is proposed, which can improve the reliability of the power system by using the main and standby modes, and prevent the communication signal from being interfered during transmission. Through the active impedance measurement system of multi-channel ports, the phased array data of the unit are collected. Finally, the parameters of the active port, the mutual coupling of the elements in the array and the standing wave of the single element port in the array are measured respectively to obtain the multi-channel impedance measurement value. Experimental results show that the proposed method has good reliability, high precision and strong intuition.
