摘　　要：低压电力线载波设备广泛应用于电网低压抄表系统通信网络中。分析了低压电力线载波设备通信性能测试的必要性和重要性;提出了电力载波通信性能测试应主要包含接收灵敏度、发送性能、抗干扰能力、中继性能等内容;同时针对各项测试内容,综合运用频谱分析仪、人工电源网络、程控衰减器等设备进行了测试方法的设计和研究。本文中的测试方法目前已大部分应用于了实际测试工作中,研究成果对相关电力载波通信产品的评估、选型以及对促进相关电力载波通信产品的改进和完善具有重要意义。Power Line Carrier equipments are widely used in the communications network of AMR and AMI systems. This paper analyzes the necessity and importance of the communication performance test for low-voltage power line carrier equipments, and points out that the communication performance tests should mainly contain receiver sensitivity, transmitter performance, anti-jamming capability, relay performance and so on. Focusing on the contents of the tests, we use the spectrum analyzer, artificial power source network, programmable attenuator and other devices to study and design the test methods. The majority of the test methods introduced in this paper has been implemented specifically and utilized to the actual testing. This article has great significance to the evaluation and selection of power line carrier communication products, and also has great significance for promoting the improvement of the relevant power line carrier communications products.
