Analysis and improvement of the Influence of new measurement terminals EMC on high speed power line communication

Abstract

The new generation of power consumption information acquisition system has increasingly high requirements for local communication business bandwidth, acquisition frequency, and reliability. However, high-speed power line communication(HPLC) is prone to performance degradation due to the influence of new measurement terminals electromagnetic compatibility(EMC). This paper proposes the analysis and improvement method of the influence of new measurement terminals EMC on HPLC. First, the hardware architecture and the characteristics of the new measurement terminals EMC are introduced. Then, the influence of new measurement terminals EMC on HPLC is studied, and the test environment of the influence of new terminals on HPLC is established; Finally, combined with the typical EMC cases analysis of new measurement terminals, the effect of the improvement of the Influence of new measurement terminals EMC on HPLC is verified. The research results show that the HPLC attenuation performance by referring to the method in this paper is significantly improved, and achieves the similar effect as the standard I concentrator. The method in this paper can provide effective technical support for the construction of a new generation of power consumption information acquisition system.
