The invention discloses a method for testing a power line carrier technology in power distribution and utilization communication. The method is characterized by comprising the following steps: running a test program at a server and a client in a coordinated manner to simulate a preset application scenario, and loading an interference source on a power line to introduce noises; selecting PLC equipment and power supply environments, and recording test data; testing the PLC equipment by using a preset modulation algorithm and a preset physical layer rate; continuously increasing data transmission requests of the client until the network cannot normally transmit the data, and recording the number of requests at the moment as the transmission limit of the system; testing a data source of a video file by using a preset bitstream bandwidth; obtaining a transmission rate variation curve according to the transmission limit; and maintaining the network equipment and topology unchanged, changing channel noises, and obtaining the test data of which the data transmission is affected by the channel noises. By adopting the method disclosed by the invention, a strong support can be provided for the application of the power line carrier technology in power distribution and utilization.
