INTERFERENCE SUPPRESSION METHOD IN ADVANCED METERING INFRASTRUCTURAL SYSTEM, METHOD, SYSTEM AND APPARATUS FOR POWER LINE COMMUNICATION

摘要

The present invention relates to an interference suppression method in an intelligent metering infrastructure system, which can suppress interference appearing in an AMI system and an electric vehicle charging system, to a power line communication method, a power line communication system, and a power line communication apparatus. The power line communication system according to the present invention comprises: an advanced metering infrastructure (AMI) including a smart meter measuring power consumption of a power demander and an energy management system (EMS) and then transmitting the measurement to a power supplier; and an electric vehicle charging device connected to the AMI system through a power line, and charging a battery of an electric vehicle as power is received.
