Aging infrastructureLegecy systems with static or

eletromechanical relays, and evenfirst microprocessor based relays

Workforce in transitionMaintenance and operationengineering groups memberselegible for retirement in next fewyears.

ReliabilityThere´s increasing pressure to

continually improve reliabilityand customer satisfaction.

Spending justificationRevenue challenges and regulatoryinspection will drive thecosts/expenditure.

Cyber segurançaAttacks on critical infrastructure areincreasing in terms of regularity andsophistication.

Disruptive technologiesDigitalization techniques for

substation automation via IEC61850, concerns about cyber security

and asset management demandsattention by the utilities part.

Changes in business modelNew players are entering in energy

market, and among them are investorswho are non-utilities companies. This

group will be responsible by 20% oftransmission and distribution around the

world until 2020.

• All the control copper cables from VTs, CTsand apparatus (circuit breaker anddisconnectors) to the control room arereplaced by optical fibers

• The SAM600 MUs converts the analog data from theswitchyard (voltage and current) in digital signalsprovided by the SMV protocol. The binaries inputsand output are, as well, encoded in GOOSE messagesover the Ethernet network and carried out togheterSMV data.

• The RELION protection and control IEDs offers 4redundant communication networks with zerolatency and switchover, avoiding loss ofinformation in this critical mission system incase of failures N-1

• The MicroSCADA supervisory system get data from theIEDs and show the real time status of the substationvia the single line diagrams, event and alarm lists. Thearchitecture of such system contains 2 GPS clocks tooffers a 1 microsecond synch time to the entirenetwork architecture

December 11, 2017 Sources: ABBSlide 7

The station and process bus togheter offers thefollowing services. using the 7 OSI layers:

Vertical communication over MMS: Data exchangeamong IEDs and supervisory system;Horizontal communication with GSE messages:Information between the IEDs;Process communication: GSE for binary signalsbetween the IEDs and the merging units, SMVmessages for analogs such as currents and voltages;IEEE 1588 (PTP) for devices synchronism, accuracyaround 1 µs;Network redundancy in IEC 62439-3 standard (PRPand HSR).

How to deal to cyber hazards & standardsCyber security approaches

December 11, 2017 Slide 11

IEC 62443*IEEE 1686 IEC62351* NERCCIP

There´s different standards to deal to sensitive data protection in a substation. These mechanisms are aligned to the digitalsubstation philosophy once the data and network communications were expanded with the introduction of process bus. Anyway, more

attention is requited from utilities regarding this issue
