Design and implementation of NMS using SNMP for AMI network device monitoring

KEPCO developed meter reading system based on AMI (Advanced Metering Infrastructure) over PLC (Power Line Communication) network for low-voltage customers. Currently, meter reading system of KEPCO operates 2.5 million low-voltage customers and will be 22 million until 2020. This paper introduces the AMI NMS (Network Management System) to monitor the network operating status of DCU and PLC modem for AMI network operation. AMI NMS collects property data of network device, network topology information, communication performance information, fault information, and etc. using SNMP (Simple Network Management Protocol). It analyzes collected data and controls network devices by remote access. This paper introduces main functionalities, designed context, implemented service screen and operational result.
