Abstract:
To solve the problem that the existing advanced metering infrastructure can not access synchronously and fairly for all meters in smart grids,an interaction communication model based on orthogonal frequency division multiple access is proposed to realize a communication system optimized for the low voltage power lines.A time-varying and selectable frequency power grid channel model is constructed using adaptive bit-loading and low density parity check coding technique and a transceiver is developed based on this model.The simulation experiments show under the conditions of 10-3 bit error rate,the transceiver provides a fair access from the head end to multiple meters in smart grids synchronously,the overall effective power of each instrument is about 1 Mbps,and the channel model can be optimized based on the characteristics of the grid structure.
