摘　　要：对低压电力线载波通信技术方案的决策,要依据有可比性的测试数据。通过选取某一典型的抄表台区,对多个载波抄表厂家产品在同一环境下,影响载波通信效果的信号调试方法、载波频率、组网算法等主要因素进行测试分析,介绍了测试系统结构以及测试结果。测试结果的分析可供低压电力线载波通信方案选择时参考。The decision on technical scheme of the low-voltage power-line carrier communication should be based on the testing data with comparability.Through selection of a typical meter-reading area and setting different company＇s product under the same environment,the main factors,such as signal testing method,carrier frequency,network algorith etc.,which can affect carrier communication quality,are tested and analyzed.Structure of testing system and testing consequence are introduced.The analysis of testing result provides the reference to the scheme selection of the LV power-line carrier communication.
