1 Integrating IEC61850 in the Eandis Grid

4 Introduction Eandis and substation concept HV/MV primary substation - TS Double busbar cubicle MV secondary substation - SS Single busbar cubicle 2 or 3 busbar linear sections 2 to 4 busbar sections in O-shape Always involving ELIA Possibly involving other DNO( s) Rarely involving other DNO( s) All position indications, measurements, alarms and control signals implemented using classical wiring (no experience with substation protocols, eg 103)

5 Transition to IEC61850: Study/PoC 2011 Study Time and Proof-of-Concept What is IEC61850 all about? What can IEC61850 do? What can it do for us? The goal Test the technology in real-life substation Test multi-vendor feasibility Estimate impact on existing processes

6 Transition to IEC61850: Study/PoC The result

7 Transition to IEC61850: Study/PoC Conclusions: Multivendor works, but different tooling is too complex Standards not mature enough regarding interoperability, too many vendor specifics IEC61850 added value Wiring can be replaced with standard configurations More measurements (U, I, P, Q, ) More position indications More detailed alarms Increased workload, Need to work with standard templates, Ease of use is mandatory

9 MV secondary substation Switching substation RTU MMS only COUPLING OC OC OC DIFF DIFF VOLTAGE Distribution loop feeders Primary substation feeders

10 Transition to IEC61850: Purchasing European Tender: New or completely renovated (25 to 50 subst/year) HV/MV primary substations (full IEC61850) MV secondary substations (full IEC61850) All expansions of existing substations Using the technology that was standard at the time of substation s first commissioning (= classic wiring) No hybrid IEC classic wiring Protections, RTU s, switches for next 6 years Single-sourcing: RTU and Protection relays from the same vendor Direct Sales: support is essential!

11 Transition to IEC61850: Writing a tender Classic specifications Protection requirements Hardware requirements New specifications Protection requirements Hardware requirements Communication certificates Display requirements Software specifications When writing specifications, take into account that multiple iterations with all stakeholders will be necessary! Don t forget to involve your technicians. Their experience, expertise and involvement in spec-writing is a critical success factor! Write functional requirements taking into account the useability, just the technical specifications are not enough!

12 Transition to IEC61850: Evaluating the tender Classic scoring model Compliance to specs Cost of devices New scoring model Compliance to specs Cost of devices Support Minimum requirements Training Ease of use of software TCO Key differentiators Ease of use of hardware Demo by vendor Introduce end-users early turn them into ambassadors Scoring should be done by the engineers and the end-users! Don t be afraid to make the demo problem complex! If the vendor can t solve it, chances are you won t be either after you signed the contract!

13 Transition to IEC61850: Preparing the rollout 5 Days of Training Train the technicians (>50) General TCP/IP & Ethernet concepts IEC61850 and IEC RTU Software tools Software tools Commissioning s Commissioning RTU s Commissioning and testing substations...and give them the necessary hard- and softwaretools!...

14 Transition to IEC61850: Training and simulation

15 Transition to IEC61850: Take the plunge May 2013: first MV secondary substation Putting training courses to the test Finetuning procedures and processes Fixing final bugs in configurations Consolidating for next 6 years

16 Transition to IEC61850: take the plunge Second half of 2013: full IEC61850 s and RTU s using IEC61850 is now the de-facto standard for MV secondary substations Development of processes and procedures for HV/MV primary substations has been completed: first project end 2014

17 MV primary substation Transformer substation RTU MMS and Goose INTERFACE To TSO COUPLING DIF DIF DIF To switching substation VOLTAGE

18 Transition to IEC61850: Take the plunge Conclusions Transition is hard, but feasible Key success factors Good, easy to use software tools Involvement from decision makers to adopters Extensive spec, including all aspects of the transition Use standard, multi-purpose, reusable templates IEC61850 should be a mean to solve a need, not a goal per se

19 Other applications of IEC Decentralised production systems Above 1MVA or when N-1 situation is not guaranteed Why not talk to a wind turbine directly?
