Abstract
In current power line communication(PLC)networks,there still exists great difficulty to measure the sig-nal power and the time delay,and the lack of effective path weights and direction is also a problem in the process of network establishment.Aimed to solve these problems,this paper proposes an indirect measuring method based on the AMI measuring parameters.By obtaining the circuit voltage,current,and phase parameters from the smart meters and concentrator of AMI system,the value of circuit voltage loss and the voltage direction can be calculated according to Kirchhoff's law,which belongs to the different phase line based on the load center of the low voltage distribution net -work.Moreover,the power line distance can also be achieved based on the material parameters, and the indirect measurement of the communication network path value and direction can be realized.In order to verify the effective-ness of the method,this paper proposes a p-persistent CSMA flooding network scheme based on AMI parameters.Ex-perimental results show that the application of AMI parameters plays an important role on reducing the depth of the re -lay and improving the networking delay.关键词
