This paper studied communication performance test method which can be used for the power line carrier communication technology of the smart grid, presented the sensitivity range squeeze algorithm based on fixed communication frequency, developed a test system for testing communication performance of carrier communication unit, and developed automatic test software used in the test system according to the characteristics of low voltage meter reading carrier communication channel. The system can change channel parameters of the power line carrier communication to test the receiving sensitivity of the carrier communication technology solutions to three different kinds of center frequency. The test results show that the test system can accurately measure the working parameters of data collection terminal and carrier meter so as to meet the system design requirements.
