2 Current challenges and changes facing utilities Aging infrastructure Legecy systems with static or eletromechanical relays, and even first microprocessor based relays Reliability There s increasing pressure to continually improve reliability and customer satisfaction. Disruptive technologies Digitalization techniques for substation automation via IEC 61850, concerns about cyber security and asset management demands attention by the utilities part. Risks Avoid Manage $ Costs Minimize Optimize Workforce in transition Maintenance and operation engineering groups members elegible for retirement in next few years. Training Network computers and its protocols, topologies and communication redundancy. Spending justification Revenue challenges and regulatory inspection will drive the costs/expenditure. Changes in business model New players are entering in energy market, and among them are investors who are non-utilities companies. This group will be responsible by 20% of transmission and distribution around the world until Performance Exceed Meet or beat Cyber segurança Attacks on critical infrastructure are increasing in terms of regularity and sophistication.

5 A full Digital Substation The resources available on an IEC station and process bus application with ABB Ability ABB Ability on digital substation journey LEVEL 2 Control room MicroSCADA supervisory system LEVEL 1 Control room Protection and control IEDs LEVEL 0 The SAM600 merging units IEC standard LEVEL 0 The substation swichyard ABB Ability TM On Prem or Cloud The MicroSCADA supervisory system get data from the IEDs and show the real time status of the substation via the single line diagrams, event and alarm lists. The architecture of such system contains 2 GPS clocks to offers a 1 microsecond synch time to the entire network architecture The RELION protection and control IEDs offers 4 redundant communication networks with zero latency and switchover, avoiding loss of information in this critical mission system in case of failures N-1 The SAM600 MUs converts the analog data from the switchyard (voltage and current) in digital signals provided by the SMV protocol. The binaries inputs and output are, as well, encoded in GOOSE messages over the Ethernet network and carried out togheter SMV data. All the control copper cables from VTs, CTs and apparatus (circuit breaker and disconnectors) to the control room are replaced by optical fibers December 11, 2017 Slide 5

6 A full Digital Substation The benefits overview Sceneries: From conventional to digital What happen inside the control room? The direct impacts of a digital substation December 11, 2017 Slide 6

7 Protocols and Ethernet allocation IEC and 9-2 togheter Protocols and services The station and process bus togheter offers the following services. using the 7 OSI layers: Station Computer Gateway 1 Vertical communication over MMS: Data exchange among IEDs and supervisory system; Station bus 2 Horizontal communication with GSE messages: Information between the IEDs; GOOSE 3 4 Process communication: GSE for binary signals between the IEDs and the merging units, SMV messages for analogs such as currents and voltages; IEEE 1588 (PTP) for devices synchronism, accuracy around1µs; Network redundancy in IEC standard (PRP and HSR).

8 Protocols and Ethernet allocation The sampled values in process bus Merging units and SMV according IEC LE 1 Which signals are transmitted in a SMV frame? Four currents, four voltages and their quality information. 984 bits This is the size of a typical SMV frame 4800 It s the number of samples in one second in a 60Hz frequency rate SMV frame captured with the IEC State of art testing tool ITT600 5Mb/s It s the Ethernet network bandwidth allocated for a single SMV frame December 11, 2017 Slide 8 Sources: ABB

10 Cyber security approaches Unauthorized access or attack December 11, 2017 Slide 10

11 Cyber security approaches How to deal to cyber hazards & standards IEEE 1686 IEC 62443* IEC62351* NERC CIP There s different standards to deal to sensitive data protection in a substation. These mechanisms are aligned to the digital substation 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 December 11, 2017 Slide 11
