AMI – Observations

Differences between systems Proprietary Communication Technology System logging and auditing Device registration – device dependant

Collector Meter Substation metering Other (smart grid devices, etc)

Network management interfaces Outage reporting Troubleshooting Monitoring performance System configuration and upgrades

AMI – Observations (Cont.)

AMI communication vendors are not interoperable for maintenance and management Meter Collector/Access Point/Mesh Gate/Take out

point/Cell Relay/Tower Gateway Base Station/ Base Station

HAN ESP interface managed and implemented different between vendors

AMI-Network TF Proposal

Define the devices and well defined points of interoperability within the AMI network for maintenance

Define the benefits of interoperability between AMI network maintenance components to utilities Sharing backhauls

Gas AMR meters Water AMR meters

Hybrid AMI systems Point to Point and mesh and PLC

Proposed TF Scope

Evaluate existing Maintenance Use Cases Define New Maintenance Use Cases Define System Functional Requirements for

AMI meters to the AMI head end for maintenance/lifecycle purposes

Identify areas within an AMI network that are viable for maintenance interoperability

Scope is outside of OpenHAN and the Zigbee/Homeplug efforts

Input from the Group???

Evaluate Existing Use Cases

SCE use cases S1 AMI system recovers after power outage,

communications or equipment failure U1 Utility installs, provisions and configures AMI

system U2 Utility manages end-to-end life-cycle of the meter

system U3 Utility upgrades AMI system to address future

requirements Other Utility use cases AMI Vendor use cases

Define New Use Cases

Focus on maintenance life cycle related activities for the meter thru the head end system

Avoid HAN use cases with the exception of the AMI Communication interface with the ESP

IP/3rd party gateways

Functional Requirements

Create a SRS (system requirements specification) similar to OpenHAN’s efforts

Derive requirements from the use case review

Focus on the AMI head end to the meter from a network maintenance perspective
