Issues with Stand-alone meter readingHighly Person dependant.Human errors cannot be avoided.Accessibility of meters in rural/ Agricultural zones.Energy Audits performed based on bill collection which is highly inaccurate.Billing done mainly on estimated/ monthly average basisInability to monitor and control discrete loadsBilling cycle requires excessive time.Meter data used only for billing, cannot help in analysis like demand analysis, energy audit, pinpointing losses, etc.

Smart Metering and IT: An opportunity to Leapfrog

Why RMS ?

Critical Benefits from RMS

Ability to detect tamper events and outage occurrences.Remotely Connect/ disconnect power supply through meter.Calculate transformer loading and sizing from interval data15 minute interval data gives accurate load information for supply scheduling, switching operations, planning etcMonitor voltage at each premise to know conditions when to operate capacitor switches or regulatorsConsistent and granular data for improved accuracy

Connectivity in AMR Architecture1. GSM Based Communication Single stage communication between Meter and central station through GSM Modem

2. Hybrid Communication Two stages of communication in AMR System

GSM Based Communication

Hybrid Communication

Two stages of communication in AMR System

Stage-1 Meters and Data Concentrator Unit (DCU):Communication channel used between meters and DCU is power Line. Stage-2 DCU and Host Central Station (HCS): Communication channel used between DCU and HCS is the standard GSM, CDMS, RF Network.
