Interest of SmartLife gather & coordinate individual effortsat the European level to increase efficiency



Organization & Objectives

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 / practicesIdentify best practices

Prepare / launch common actions

Cable systems : some key results

SmartLife


Failure analysisGood aging of both paper & polymeric links

Database to improve statistics on technologies & failures

Failure & aging mechanismsPartial discharges for paper cables (thermal & mechanical constraints)

Water-treing for polymeric cables (water ingress & insulation imperfection)

Lab testsCommon procedures on samples removed from the field

Common database for sharing of test results


Cable systems : some key results

SmartLife


Health IndexPotential powerful tool to represent overall health of equipment

Need of development vs. data quality to help define AM policies

DiagnosticsApplied by utilities as potentially useful to determine link condition

Need of improvement to really support AM decisions (lifetime extension)

Technical specificationsInternational standards as a minimum quality level of equipment

Need of complementary tests to reach the required quality level


Power Transformers : some key results

SmartLife


Failure analysisFew aging allowing a real opportunity of lifetime extension

Needs of maintenance & condition monitoring & on-line diagnostics

Questionnaire to collect experience on major failure modes

DiagnosticsLists of main techniques used & major parameters to collect

Aging mechanismsLong term aging mechanisms important for lifetime estimation

Post mortem analysis to estimate scrapped power transformer condition

Potential innovative technologies & techniques


Distribution network AM : some key results

SmartLife


Context & PracticesGeneralization of Risk Management concept

Increasing focus on quality by regulators : from SAIDI to specific indicators

NeedsNetwork automation strategies to improve performance

Heath Index for critical equipment coherent with failure statistics

Aging models for maintenance / renewal decisions & tariff negotiation

Distribution network AM : some key results

SmartLife


ToolsStrategic level tool to guide medium / long term CAPEX / OPEX trajectories

Operational level tool to optimize decisions on short term expenditures

Quality & MethodologyGeneral 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


SmartLife2 perimeter

SmartLife


SmartLife2 = to take benefit from implemented networking of experts and asset managers on Distribution issues

Simple cooperation = data exchange & information sharingAdded Value of SmartLife !

Partners = DSO & R&D working within 5 User Groups Cable Systems, Overhead Lines, Power Transformers,Distribution Transformers, Distribution Network AM
