SmartLife: Coordination for Effcient T&D Network Management

1. SmartLife = European coordination Actionin Asset Management of T&D Networks • SmartLife initiative in 2009-2010 • Focus on some actions & results • Continuation in 2011-2012 : SmartLife2 Guillaume & SmartLife Core Group – France – S1 – Paper 1095

2. SmartLife Context & Needs & Benefits • Management of current aging networks • Transition to Smart Grids with innovative technologies  Call for optimization of network AM based on : • Knowledge of aging mechanisms & estimation of remaining lifetime • Definition of equipment performance • Relevant AM processes  Need to consider equipment criticality through Risk Management approach Interest of SmartLife  gather & coordinate individual effortsat the European level to increase efficiency Guillaume & SmartLife Core Group – France – S1 – Paper 1095

3. SmartLife • SmartLife = collaborative exchanges through a large networking of Utilities & Instituts • 26 partners from 9 countries • 12 DSOs, 6 TSOs,5 R&D, 3 Universities • Consortium Committee, Core Group, User Groups • 60 experts & asset managers • Exchanges = sharing of data / knowledge / practices • Identify best practices • Prepare / launch common actions Organization & Objectives Guillaume & SmartLife Core Group – France – S1 – Paper 1095

4. Network components ~ 40 experts SmartLife AM processes ~ 20 asset managers OVERHEADLINES led by RSE POWER & DIST TRANSFORMERS led by SINTEF CABLE SYSTEMS led by SINTEF TSO ASSET MANAGEMENT led by KEMA DSO ASSET MANAGEMENT led by ENEL User Groups COMPONENTS User Groups ASSET MANAGEMENT 5 User Groups Guillaume & SmartLife Core Group – France – S1 – Paper 1095

5. SmartLife Cable systems : some key results • Failure analysis • Good aging of both paper & polymeric links • Database to improve statistics on technologies & failures • Failure & aging mechanisms • Partial discharges for paper cables (thermal & mechanical constraints) • Water-treing for polymeric cables (water ingress & insulation imperfection) • Lab tests • Common procedureson samples removed from the field • Common database for sharing of test results Guillaume & SmartLife Core Group – France – S1 – Paper 1095

6. SmartLife Cable systems : some key results • Health Index • Potential powerful tool to represent overall health of equipment • Need of development vs. data quality to help define AM policies • Diagnostics • Applied by utilities as potentially useful to determine link condition • Need of improvement to really support AM decisions (lifetime extension) • Technical specifications • International standards as a minimum quality level of equipment • Need of complementary tests to reach the required quality level Guillaume & SmartLife Core Group – France – S1 – Paper 1095

7. SmartLife Power Transformers : some key results • Failure analysis • Few aging allowing a real opportunity of lifetime extension • Needs of maintenance & condition monitoring & on-line diagnostics • Questionnaire to collect experience on major failure modes • Diagnostics • Lists of main techniques used & major parameters to collect • Aging mechanisms • Long term aging mechanisms important for lifetime estimation • Post mortem analysis to estimate scrapped power transformer condition • Potential innovative technologies & techniques Guillaume & SmartLife Core Group – France – S1 – Paper 1095

8. SmartLife Distribution network AM : some key results • Context & Practices • Generalization of Risk Management concept • Increasing focus on quality by regulators : from SAIDI to specific indicators • Needs • Network automation strategies to improve performance • Heath Index for critical equipment coherent with failure statistics • Aging models for maintenance / renewal decisions & tariff negotiation Guillaume & SmartLife Core Group – France – S1 – Paper 1095

9. SmartLife Distribution network AM : some key results • Tools • Strategic level tool to guide medium / long term CAPEX / OPEX trajectories • Operational level tool to optimize decisions on short term expenditures • Quality & Methodology • General trend for continual improvement program (PAS 55-1 & -2 widely used) • Data collection = key point of AM ! • Recommandations on data to be collected  3 levels : Essential / Relevant an available / Interesting but rarely available • Opportunity to use mobility tools Guillaume & SmartLife Core Group – France – S1 – Paper 1095

10. SmartLife • SmartLife2 = to take benefit from implemented networking of experts and asset managers on Distribution issues • Simple cooperation = data exchange & information sharing • Added Value of SmartLife ! • Partners = DSO & R&D working within 5 User Groups • Cable Systems, Overhead Lines, Power Transformers,Distribution Transformers, Distribution Network AM • 2 annual topical Worshops by each User Group, free of charge • Launch of possible funded studies between interested partners SmartLife2 perimeter Guillaume & SmartLife Core Group – France – S1 – Paper 1095

11. SmartLife Proposed Workshops in 2011-2012 • Cable Systems • Improvement of specifications • Diagnostic techniques • Cable sample tests • Data collection / Health Index • Overhead Lines • Data collection & Analysis • Inspection & Maintenance • Aging • CAPEX-OPEX optimization • Power Transformers • Maintenance • Monitoring & Diagnostic • New technologies • Data collection & Analysis • Distribution Transformers • Data collection & Analysis • Eco-efficient transformers • Knowledge sharing on aging • Remaining lifetime estimation Guillaume & SmartLife Core Group – France – S1 – Paper 1095

12. SmartLife Proposed Workshops in 2011-2012 • Asset Management of Distribution Networks • Strategies of network automation (July 2011) • Impact of DG (& EV) integration on networks • Asset aging & AM methodologies : Risk & Health Indexes • Data collection, tools, regulation, AM strategies SmartLife2 in finalization Partners welcomed !
