Commercial Operations
Financial Evaluations
Energy Audit
Distribution Business (Franchisees, etc.)
Grid Control, Load Despatch
Load Survey
Power Purchase, ABT
SCADA
Statistical Analysis, Quality Evaluation, etc.
Existing Scenario
Traditionally, Utilities Have…
• Variety of Makes, Models, Types &Versions
• No Uniform Standard either in Features,
Protocols, Communication Methods
• Incompatible Softwares, Platforms
• No Uniform Standards
• No Single Common Meter Reading
Instrument Compatible for the existing
Meter Base
Communications
• PSTN, GSM, GPRS, EDGE, CDMA,
RF, PLCC, ZigBee, Wi-Fi, WIMAX
• Modems with interoperable Protocols
• Operating Systems: DOS, Win98, Win
XP, Vista, Linux, etc.
• Database: SQL Server, Oracle, Access,
etc.
Vision For Future
Smart & Intelligent Energy Meter with..
• Capability to Read KWh, KVAh & PF as
Billing Parameters
• In-built Communication of its own
• Load Survey Data Storage For 45 Days
• Selective Download Facility from Stored Data
• Wireless Communication preferable between
Consumers’ Gadgets
• PLCC Communication over the LT Lines
Wish List
• 2-Way Communication Facility
– To Display Bill Amount, Due Date, etc.
• Voice Provision
– To Announce Bill Amount, Due Date, etc.
• Inter-Operable Communication Capability
with other Devices in a House or Vicinity
Accuracy of Meter
• Undue Importance is being given by Many
to Meter Accuracy; But…
– High Capacity Meters for Low Loads
– Low Power Factor
– Higher CT Ratios Adopted
– Higher CT, PT Accuracies, etc.
should make anybody to think twice before
insisting Higher Accuracy better than 0.5
Class
Any Questions?
