Power line communication uses the power line of power system as a communication medium, so its convenience is unparalleled. Meanwhile, it is considered to be one of the best communication technologies in smart grid. This technology must be more and more widely used in the future. However, the whole network of PLC shares one channel, leading to shortage of channel resources. The time variation of PLC system also contributes to reduce channel utilization. In this paper, a hybrid channel allocation method based on PRIME will be proposed. It combines the strength of TDMA and CSMA/CA, which can significantly avoid collision, increase throughput and decrease transmission delay. It is emphasized on TDMA, and CSMA/CA is auxiliary. The idea of time-sharing transmission is used in the method. The results of simulation will show that the method is feasible and effective. The method is of great significance to improve overall performance of PLC.
Keywords:power electronics and power transmission; powerline communication; hybrid channel allocation; PRIME; TDMA; CSMA/CA
