17 Horizontal GOOSE communication General Local SCADA Station bus IEC Standardized horizontal communication Replaces hard-wiring between IEDs GOOSE = Generic Object Oriented Substation Event GOOSE is used to broadcast events to peer IEDs in a substation Can in principle transmit any kind of process data between the IEDs Ethernet technology offers a fast and reliable station bus for transfer of data October 30, 2014 Slide 17

18 Horizontal communication: GOOSE SCADA Engineering GPS Ethernet Switch Ethernet Switch Ethernet Switch Ethernet Switch Ethernet Switch Ethernet Switch Ethernet Switch October 30, 2014 Slide 18

19 IEC communication services The mechanism of GOOSE messages Without any changes, the GOOSE-message is repeated with T max until the next event / change. t max = 1024ms t max = 1024ms time In case of a information-change, the GOOSE-message will be repeated within T min. The repetition frequency is lowered until T max is reached. t max = 1024ms t min = 2ms t max = 1024ms time October 30, 2014 Slide 19

20 Station interlocking Hardwired interlocking bus IEC Hardwired Interlocking Bus October 30, 2014 Slide 20 Features The distribution of information requires many cables and auxiliary Advantages Disadvantages contacts No special tools or training are required to test and maintain hardwired installations Hardwired installations can be extended or commissioned piece by piece, with minimal or no modification of existing IED configurations If, for example, position indications for interlocking are directly distributed via the primary equipment s auxiliary contacts, the number of devices in the signal change is minimized, which reduces the risk of failure.

21 Station interlocking IEC interbay bus (GOOSE) IEC October 30, 2014 Slide 21 Features GOOSE Generic Object Oriented Substation Event Reduction of copper cabling between panels All GOOSE data is continuously supervised, allowing the immediate initiation of remedial actions in case of failure, increasing the availability of the substation Fewer in- and outputs are required in the IEDs and auxiliary relays The selection of signals to be exchanged can be modified easily without needing to change the inter-panel cabling Hardwired signal exchange for station interlocking usually introduces an external signal voltage to the panels, posing a potential hazard. GOOSE communication eliminates this risk. The transmission speed of GOOSE signal exchange matches or outperforms conventional signal distribution

22 Application examples Circuit-breaker failure protection OK, I hear you! I ll open my Breaker X REF615 IED B X REF615 IED A GOOSE message My Breaker is not opening! Activate Breaker failure scheme IED B (outgoing feeder) detects a fault, issues an opening command to its breaker and starts the breaker failure protection The breaker of the outgoing feeder fails to open and after a set time delay the breaker-failure protection in IED B sends a BFP trip command to IED A as a GOOSE message After receiving the GOOSE message IED A issues an opening command to the incoming feeder breaker and the fault is cleared October 30, 2014 Slide 22

23 Introduction to process bus What is process bus? Station level IEC station bus Bay level IEC process bus IEC describes all communication in the substation The station bus transmits information between the bay level IEDs, and between the station level and the bay level The process bus connects the process to the bay level Process level MU MU MU MU MU MU NCIT NCIT October 30, 2014 Slide 23 MU = merging unit NCIT = non-conventional instrument transformer

24 What is IEC process bus Process bus Control Protection Optical Ethernet network between primary equipment and protection and control IEDs Process bus replaces parallel copper cabling with a few fiber optics Control IEC Protection Isolation of primary process through optical cabling Eliminates negative impact of long copper cables Compliant with IEC 61850, the standard in substation communication October 30, 2014 Slide 24
