1 Time-Critical Applications - applying the latest tools and techniques to guarantee QoS for time-critical applications and services over IP/Ethernet/MPLS telecom networks Pedro Gama, Head of SCADA & Telecom Department at EDP Distribuição, SA SGTech Europe 2015 September 22 th Amsterdam

2 AGENDA EDP and EDP Distribuição in brief Communication network and technologies The (new) requirements of EDP EDP s IP/MPLS trials Conclusions and next steps 2

3 From a local electricity incumbent to a global energy player with a strong presence in Europe, Brazil and considerable investments in the USA 3

4 EDP is a Portuguese utility that engages in generation, distribution and supply HV network MV network LV network Generation Transmission Station VHV/HV Substation HV/MV Secondary Substation MV/LV Retailer/ Consumer EB Main figures EDP Distribuição km 416 HV/MV Substations km MV/LV Stations km 6,1 Million Customers MVA installed MVA installed Level of monitoring and automation, today 4

5 The National Electricity System includes EDP Distribuição as the regulated electricity distribution company acting under a public service concession DISTRIBUTION Public Service Concession assigned to EDP Distribuição HV network MV network LV network Generation Transmission Station VHV/HV Substation HV/MV Secondary Substation MV/LV Retailer/ Consumer EB Main figures EDP Distribuição km 416 HV/MV Substations km MV/LV Stations km 6,1 Million Customers MVA installed MVA installed Level of monitoring and automation, today 5

7 EDP Distribuição Telecommunication Network Support mission critical services in a Private Network based on TDM Service TDM Communications SCADA Applications Mission-critical Services Telecontrol (remote control) of electrical facilities Teleprotection Differencial protection Real time Proprietary protocols Legacy interfaces Strict requirements G.703 or dark fiber Voice Operational Telephony Analog circuits over PDH VHF Radio network IED/Terminalserver connections Remote management of telecontrol and protection equipments Remote metering and Power Quality Dedicated circuits Modems 7

8 EDP s Challenges The SDH/PDH network served us well, but Facing obsolescence of TDM tecnology Technology limitations for operational needs Access control Complex operation and configuration Static bandwidth Increasing demand of services Number of applications high need of automation and kwnologe of the network <ex. smart(er) grids> EDP decision for standard protocols (IP based) protocol IEC Available ethernet interfaces on last generation of equipments 8

9 EDP and EDP Distribuição in brief Communication network and technologies The (new) requirements of EDP EDP s IP/MPLS trials Conclusions and next steps 9

10 The (new) requirements of EDP Provide ethernet interfaces for upgraded and new sites (primary and secondary substations) Unified Plataform Network, Applications, SLA and Support Future-Proofed Open Standards, IP-Based, Multi-Purpose Network Low Risk Robust Deployment Support, Managed Software Cost-Effective Leverage the investment Security / Compliance Non-Proprietary, Compliant with Standards, access control for users 10

14 2 vendor trials based in IP/MPLS Architecture IP/MPLS Backbone 11 (100Mb) Edge (substations) rings 108 Sites (primary HV/MV substations) Including integration of 32 IP existing sites Security infrastructure (FW, IPS, ACS and NAC) Using EDP fiber network (> 2800 Km) 14

15 2 vendor trials based in IP/MPLS Architecture Tested Services SCADA IEC SCADA IEC RS232 IP/MPLS Backbone Remote metering (Ethernet / modem) Remote management of telecontrol and protection equipments Power Quality Voip 15

17 IP circuit availability of 99,99%, however SCADA applications recorded 99,89% due to a complex chain of discrete elements (RTU s, Power Systems, FrontEnds, Servers, etc) RTU Reset Communication front-ends reset Planned maintenance RTU reset 17

18 IP circuit availability of 99,99%, however SCADA applications recorded 99,89% due to a complex chain of discrete elements (RTU s, Power Systems, FrontEnds, Servers, etc) 18 Scada availability frequency % >= 99,99% 50% >= 99,96% 75% >= 99,87% Frequency 99,99% 99,96% 99,87% 99,71% 99,22% 18

19 Bandwidth for scada applications peeks at 16 Kbits/s 19

20 Latency within expected values average 7,2 ms (between 5 to 12 ms) 20

21 Access/Edge rings - up to 10 nodes to comply with tele-protection requirements Microseconds Quantity Latency/unit Total Latency Fibre length (km) Access/Edge nodes Aggregation nodes Packetization Jitter buffer Total latency in microseconds

22 Proposed network architecture 10 Gb Backbone Layer 10 Gb Aggregation Layer 1Gb Edge Layer 22

23 EDP and EDP Distribuição in brief Communication network and technologies The (new) requirements of EDP EDP s trial with Public operator Conclusions and next steps 23

24 Conclusions - Initial effort for integrating legacy systems; - Proven technology suitable for current and future needs; - Ring Topology, although fiber layout is not always available; - Avoid copper circuits; - Environmental hardening equipment support; 24

25 Conclusions - In-box hot stand-by redundancy with fast fail-over times - Backbone and Aggregation with Dual Power, Fan and CPU board redundancy; - Edge with Dual Power and Fan redundancy; - Preferred Interface redundancy; - QoS technologies optimizes the available bandwidth utilization BUT it does not create bandwidth: - Increased Edge ring from 100Mb to 1Gb - Aggregation and Backbone 10Gb rings, scalable Backbone to 40Gb 25

26 and next steps - Public tender for roll-out of IP-MPLS network; - Implement a lab/test network with winner for testing proposed architecture bandwidth, latency, resilience schemes, etc, before initial deployment; 26
