摘　　要：分析了用电信息采集系统中存在的主要电磁骚扰,提出了用电信息采集通信中电磁骚扰的测量方案,并通过实验测得了节能灯工作时向电力线发射的电磁骚扰;提出了电磁骚扰对用电信息采集系统通信性能影响的测试方法,在电磁骚扰产生设备开启、关闭2种情况下分别测得了5家低压电力载波通信模块的抄表成功率。试验结果表明:某些用电设备会产生较强的电磁骚扰,当载波通信模块的中心频率对应的电磁骚扰幅值较高时,其通信性能会明显下降。This paper analyzes the main electromagnetic disturbance in the electricity information collection system,and a measurement scheme of electromagnetic disturbance in power enformation collection is proposed.When a energysaving lamp is working,it will transmiss electromagnetic disturbance to the power line,the electromagnetic disturbance is measured by experiment in this paper.The method is proposed to measure the effect of the electromagnetic disturbance in the electricity information collection system.In two cases of the electromagnetic interference source generating device is opening and closing,the success rates of meter reading are measured,the measurements include five kinds of low voltage power line carrier modular.The result of test shows that some electrical equipment produces strong electromagnetic interference,when the center frequency of the communication module correspond to the high disturbance amplitude,the communication performance of the low voltage power carrier is obviously decreased.
