摘要
低压电力线载波通信技术已广泛应用于智能计量设备中,但由于恶劣通信环境严重影响系统的稳定性,有必要建立电力线信道模拟平台,实现对载波通信性能的测试。文章基于对低压电力线信道特性的分析,完成了对电力线负载、衰减和噪声模拟器的原理分析与设计实现,并在此基础上建立了智能计量设备载波通信测试系统。开展低压电力线载波通信性能测试,并对测量数据和结果进行了分析。测试系统的建立为相关设备的载波通信性能评估和选型提供了有效的手段和参考依据。
Low - voltage power line carrier communication is widely used for smart metering equipment. Due to the severe communication conditions that seriously affect the stability of the system,it is necessary to establish simulation platform for power line channel and test its communication performance. The analysis,design and implementation of the simulators for power line load,attenuation and noise are completed based on the analysis of low - voltage power line channel characteristics. The carrier communication test system for smart metering device is established hereby. The low voltage power line carrier communication performance is tested,and the measurement data and test results are analyzed. The establishment of the test system provides an effective method for power line carrier communication performance evaluation and associated equipment selection.
