The Cisco Substation Automation answer permits utilities to beef up new industry fashions, enlarge capability, combine renewable power assets, scale back operational prices, scale back dangers to grid operations, and meet regulatory necessities. The answer helps extra than simply the core supervisory regulate and information acquisition (SCADA) programs, including key use instances involving coverage of key property and tool control. Its generation upgrades and community control features scale back operational prices by way of decreasing the community footprint and automating key duties. The community infrastructure can beef up extra units and care for extra bandwidth with extra resiliency and new features for the community, reminiscent of time synchronization and web hosting programs. The Substation Automation answer builds at the visibility and safety of our Grid Safety method to meet the wishes of a variety of transmission and distribution substations. The up to date answer is helping utilities conquer the next industry and operational demanding situations:

• Rising selection of procedure and station bus units riding upper bandwidth necessities
• Restricted house and tool in substations for apparatus
• Wish to scale back cybersecurity dangers by way of offering visibility into and segmentation of substation units and site visitors flows.
• Loss of networking abilities in grid operations groups
• Necessities to Combine and observe legacy units
• Regulatory necessities, particularly NERC-CIP and NIS2
• Wish to scale to beef up extra substations

The Substation Automation answer is helping utilities conquer those demanding situations and lays the basis for extra dependable, sustainable, environment friendly grid operations at a lower price. Key options of this answer come with:

• Extra ports and quicker speeds: Advent of the IEC 61850-3 and IEEE 1613 compliant Cisco Catalyst IE9300 Rugged Collection Switches with 28 Gigabit Ethernet fiber ports for protected, dependable, low-latency station and procedure bus conversation
• Upper port density by means of stackable switching
• Higher reliability: Strengthen for a spread of resiliency and synchronization protocols
• Multifunctional router: Advent of IEC 61850-3 and IEEE 1613 substation qualified Cisco Catalyst IR8340 Rugged Collection Router and Cisco Catalyst IR1100 Rugged Collection Routers for a mixture of scalable WAN connectivity, firewall safety, and alertness web hosting
• Reliability: Strengthen for a spread of resiliency and synchronization protocols
• Higher safety: Allow extremely protected WAN with complicated firewalling, URL filtering, intrusion prevention (IDS/IPS), malware coverage, IPsec/MACsec encryption, and DNS safety. Implement community get admission to regulate the use of Cisco Trustsec and IEEE 802.1x. Achieve visibility of substation property, their conversation actions and your safety posture with Cisco Cyber Imaginative and prescient. Regulate far off get admission to into property with Cisco Safe Apparatus Get right of entry to. All constructed into Cisco networking apparatus that experience protected boot, signed firmware, and SUDI.
• Flexibility: Extremely modular platforms to beef up switching, routing, synchronization, and edge compute wishes
• Availability: Strengthen for IEC62439-3 lossless community topologies and protocols (reminiscent of Top-Availability Seamless Redundancy [HSR] and Parallel Redundancy Protocol [PRP])
• Precision: Strengthen for substation-wide time synchronization (for instance, the 2017 IEEE Precision Time Protocol – Energy Profile or IEC61850-9-3 PUP)
• Important purposes: Strengthen for substation communications reminiscent of IEC 61850, Modbus, IEC 60870-5-104 (IEC 104) and Disbursed Community Protocol 3 (DNP3)
• Simplicity: Vary of control choices, together with Cisco Catalyst Middle for substation switching and Cisco SD-WAN Supervisor for SD-WAN routing features

Evolution to phase routing and Ethernet VPN (EVPN) for substation WAN connectivity

Previous to phase routing, multi-protocol label switching (MPLS) packets had been forwarded the use of label switching as an alternative of IP-based routing, which means that the routers forwarded site visitors in response to the label and no longer the vacation spot deal with. This required handiest the “edge” routers to accomplish an IP look up, whilst intermediate “core” routers carried out just a label look up.

Sadly, MPLS didn’t take away complexity from an present community. If truth be told, it added extra complexity via further protocols and every MPLS node requiring the state to be synchronized throughout all the community. As the dimensions of networks grew, so did the state and complexity, making it harder to perform and arrange.

Phase routing depends on a small selection of extensions to Cisco Intermediate Device-to-Intermediate Device (IS-IS) and Open Shortest Trail First (OSPF) protocols. It will possibly perform with an MPLS or an IPv6 knowledge airplane, and it integrates with the wealthy multi carrier features of MPLS, together with Layer 3 VPN (L3VPN), Digital Non-public Cord Carrier (VPWS), Digital Non-public LAN Carrier (VPLS), and EVPN.

Phase routing will also be without delay carried out to the MPLS architectures without a alternate within the forwarding airplane. Phase routing makes use of the community bandwidth extra successfully than conventional MPLS networks and provides decrease latency.

EVPN

EVPN is the following technology L2VPN generation, it supplies layer-2 in addition to layer-3 VPN services and products in a scalable and simplified approach. The evolution of EVPN began because of the will of a scalable method to bridge quite a lot of layer-2 domain names and conquer the constraints confronted by way of VPLS reminiscent of scalability, multi-homing, and per-flow load balancing.

Use instances regarded as within the new Cisco Validated Designs

We now have 3 classes of services and products to believe for the delivery community:

1. Layer 3 IP founded Substation to Datacenter: IP founded Scada knowledge, IP founded CCTV, endeavor knowledge and IP telephony.
2. Layer 2 Non routable Substation to Substation: Layer 2 ethernet founded multicast protocols (reminiscent of IEC61850 GOOSE & SV), Digital device migrations (for virtualised programs) and 3rd birthday party Scada site visitors.
3. Layer 2 Substation to Substation for Conventional Teleprotection: Energy Coverage services and products, which can be low latency level to indicate the use of explicit application protocols and strict engineered paths around the community.

SEL Partnership

Cisco companions with Schweitzer Engineering Laboratories to give you the Teleprotection services and products and interfaces inside the substation, which can be by means of the SEL ICON platform. This platform supplies the interfaces required for substation coverage units whilst offering an Ethernet founded uplink to the Cisco Converged Shipping community (NCS). SEL experience in grid automation is coupled with Cisco’s Commercial substation and converged delivery community merchandise supplies a very best of breed finish to finish answer.
