2 Agenda Process bus application Large Applications

3 IEC Overview *standardization in work Control Center IEC To be harmonized with CIM IEC 61970* IEC Firewall communication to other substatons* Router IEC61850 Station Bus IED IED IEC (Ethernet) Protection & Control IEC61850 Process Bus Digital Instrument Transformer Data via IEC CT VT Merging Unit CBC x Circuit Breaker Controller

4 Benefits of IEC Process Bus Standardized communication interface on Ethernet Enabling Non Conventional Instrument Transformer Technology Saves cables and other hardware structures Saving engineering efforts Eases installation and maintenance Basis for intelligent switchgear and extended monitoring features

5 Prototype Merging Unit IEC Prototypes Off the shelve switches or Ethernet Switch Prototypes with Real Time availability Process Bus Interface Process/Station Bus Interface Merging Unit 9-2 LE 7SA 525 Distance Protection Siprotec as CB Controller Lopo Conventional Hall sensor..other types

7 Merging Unit Overview SV Vdc PS-1 SV Vdc PS-2 redundant 2x IEC61850 Kontroll-LEDs PPS SYNC Communication Extension Life 4x I (1A) IEC SPI 4x U (100/110V 3) IEC x LoPo +/-10V IEC /-8 DC/ AC z.b. ISH NCT B I Optical / Hall/..

8 Requirements for a Process Bus Communication Samples Must not get lost Samples blocking free Trip signal, non blocking, highly redundant < 1µs Time Sync via the Ethernet Client Server for e.g. monitoring and SV/GOOSE on the same wire/fiber

9 Why not a Real Time Ethernet Solution? Communication system scheduling - separate time domains for real-time and non-real-time - RTE channel Open channel (IP) RTE channel Open channel (IP) Cycle 1 Cycle 2 Cycle n E.g. 1 ms control cycle Synchronization Deterministic communication RTE data Open communication IP data

10 Bandwidth Reservation Principle of the bandwidth reservation Preprogrammed noninteruptable Data transfer inside the IRT Channel Unlimited TCP/IP-traffic in the open Channel TCP/IP TCP/IP TCP/IP TCP/IP TCP/IP reserved lane for IRT TCP/IP Exit TCP/IP IRT TCP/IP

11 Time sync over bus TRIP over bus IEC Protocol Stack combined with RTE Minor extensions, maximum effect Digitized CT/VT values IED to IED Interlocking 1ms station bus time sync Station Controller to IED communication Sampled Values GOOSE SNTP MMS Protocol suite UDP/IP TCP/IP Priority Tagging IEEE 802.1Q RTE IEC CP3/6 ISO/IEC Ethertype ISO /IEC

12 HALL LoPo LoPo CT 1 A Demonstration use of Real time Ethernet Process Bus incl. Access Switch OMICRON CPC 100 (AC / DC source) Clock, e.g. GPS Merging Unit 1 Merging Unit 2 Report Sampled Report Control: Trip of measured - GOOSE CB Values CB off onvalues 3rd party device IRT Access Switch CB-Control x Protection Relay IRT Access Switch SICAM PAS

13 HALL LoPo LoPo CT 1 A IEEE 1588 Time sync via the Bus Master Clock Output Slave Clock Output Clock, e.g. GPS CB-control Merging Unit 1 1µs time sync Protection Relay Merging Unit 2 flicker free redundant Ethernet Ethernet Bay Switch

17 Real-Time Ethernet add-on advantages Bandwidth Reservation Guaranteed response times Bumpless Redundancy In the case of interruption not even one telegram gets lost < 1µs Time Sync via the Ethernet IEEE 1588 Precision Time Protocol Redundancy for the time sync Real Time and non-real-time (TCP/IP) on the same wire/fiber All signals available at each port Conversion IEC LE to RTE in a external switch possible Other domains have the same requirements and discuss similar solutions IEEE 802.1avb Bumpless redundancy and use of IEEE 1588 is now discussed in IEC and IEEE PSRC
