Low - voltage power line carrier communication is widely used for smart metering equipment. Due to the se-vere communication conditions that seriously affect the stability of the system,it is necessary to establish simulation platform for power line channel and test its communication performance. The analysis,design and implementation of the simulators for power line load,attenuation and noise are completed based on the analysis of low - voltage power line channel characteristics. The carrier communication test system for smart metering device is established hereby. The low voltage power line carrier communication performance is tested,and the measurement data and test results are analyzed. The establishment of the test system provides an effective method for power line carrier communication per-formance evaluation and associated equipment selection.
