Aiming at the characteristics of low-voltage collecting carrier communication channel, the communication performance testing method of power line carrier communication technology which can be used in smart grid is deeply researched. The sensitivity squeezing algorithm based on the number of fixed communication is proposed. Performance test system, developed a set of automatic test software used in the test system. The system can change the power line carrier communication channel parameters, the center frequency of three different carrier communication technology solutions for receiving sensitivity test. The test results show that the test system can accurately measure the operating parameters of the data acquisition terminal and the carrier watt-hour meter to meet the system design requirements.
