【Abstract】 According to the structure and characteristics of medium-voltage networks in operation in China, the access mode and principles of broadband power line communication (PLC) on medium-voltage lines are discussed. Based on the generalization of the access equipment and the access interface, the test on the first medium-voltage PLC channel in China is completed and the result of channel test is analyzed and studied. The transmission experiment and test study on medium-voltage power lines have provided the design basis and technology support for further development of broadband PLC on the medium-voltage power lines and reference data for the future long distance access of medium-voltage lines.更多还原
