Power line communication networking technology based on AMI measurement parameters
In current power line communication (PLC) networks, there still exists great difficulty to measure the signal 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 article proposes a indirect measuring method based on the AMI measuring parameters.By obtaining the circuit voltage, current, phase parameters from the smart meters and concentrator of AMI system, the value of circuit voltage loss and the voltage directing can be calculated according to Kirchhoff''s law, which belong to the different phase line based on the load center of the low voltage distribution network. Moreover, and 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 effectiveness of the method, this article proposes a p-persistent CSMA flooding network scheme based on AMI parameters. Experimental results show that the application of AMI parameters plays an important role to reduce the depth of the relay and to improve the networking delay.
