Transcription

1 Metering Billing & CRM Conference Asia 22 & 23 May 2013, Bangkok Integrating Metering, Communications and Data Infrastructure Marcus Tyle Manager Metering Systems Strategy Energex Limited, Australia

2 ENERGEX Ltd Distribution Electricity Utility based in Brisbane, Southeast Queensland, Australia. 1.6 million customers 2.4 million meters Ergon Ltd covers rest of Qld

3 Energex Metering End to end metering systems life cycle asset management and technical and revenue data collection Regulated revenue metering in Energex manual cyclic register read Unregulated National Electricity Market Type 1-4 C&I remotely read nationally SmartGrid metering technical data PQ and Transformer monitoring and technology projects

4 Network SmartGrid Metering Update Monitoring of new LV transformers >100kVA implemented Technical Data: Phase V, I, p.f. (1 min & 10 min profile) Exception reporting of events Successful implementation using Low cost multifunction revenue Class 1 meters and GPRS IP communications with daily reading Metering Management and Head End System (data export point of truth) exporting to Network Analytics daily. Near real time access of instantaneous data

5 Metering Headend Measurement device Surveys Logs Alarms Metering Head End Implemented Inhouse design DLMS structures Interface - metering to network data Device translated and validated engineering data Measured Data Data Analysis Storage Data normalisation Data Store and Headend Derived Data Limits Exceeded Historical Planning and Trending Short term Planning and operations Tasking of Field Operations to action Near Real Time Events

6 Metering Communications Strategy Open international communication standards IP based communication IPv4 to IPv6 Transparent link between meter & data collection application Platforms GPRS evolving to LTE point to point 3 rd generation Power Line Communication PRIME or G3 evolving to IEEE Narrow Band Standard National Broadband Network

7 PRIME Power Line Communications Trial Trial confirmed PRIME OFDM PLC operated successfully on a mix of Energex underground and overhead network 50% sites with PLC. Performance expected to meet or exceed the Australian Smart Metering Infrastructure Minimum Functionality Specification Maturing with firmware updates improving performance Identified benefits of PLC Avoids public concern over wireless technologies Lowest cost communications interfaces Phase identification and accurate LV network connectivity map No communications spectrum required Concentrator provides both Distribution Transformer monitoring and data collection facilities as incremental cost. Full two way communications with guaranteed delivery Reduced risk from cyber security with encryption

9 Business Drivers for Smart Metering Proposed Regulatory AEMC Power of Choice when approved driving industry and metering change: Network to install smart meters & comms for new and replacement Competitive metering provision to all customers (small) Enable data services to customers for informed energy use decisions Reducing cost Specifications, tenders and systems implementation joint with Ergon Smart Metering Systems to be based on interoperable protocols and data interchange standards (CIM) Metering Management System supports multiple data streams Supply contractor operation and load mgt LV network and solar PV data for decision making Customer safety Functionality to reduce truck rolls and reduce operating cost

10 Metering System Direction Transition from proprietary to interoperable meter protocols DLMS/COSEM (IEC62056) - core data definitions meeting our revenue & technical data. Various regional interpretations UK SMETS ANSI C12 Single Metering Management Systems for all data streams types and differing brands of meters Automation of all data transitions - meter and backend systems System generational change & interoperability with new metering systems planned for 2015

11 Key Issues - Information Management Increased end to end systems complexity Multidiscipline team (power engineering, communications, IT) System integration challenges Developing the tactical and operational strategy cross business with stakeholders Understanding the data touch point interchanges and interfacing to Corporate applications, work & asset management & CIS. Data mastering and referencing in systems one source of truth? End to end security Planned scalability Right expertise

12 Smart Metering & SmartGrid Systems Future View

13 CLOSING REMARKS Regulatory drivers for Smart Metering - system generational change. Move from proprietary based protocols to interoperable international standards metering, data interchange & telecommunications. Significant increase in IT systems sizing & cost. Integration and process change to extract new value from Smart Metering functionality. Leverage productivity and technical data opportunities for Network. Understand the roadmap between your strategy and vendors to ensure alignment. Co-operation for regional input into interoperable standards for metering systems?
