Subsequent era digital substation WAN

The Cisco Substation Automation answer allows utilities to assist new enterprise fashions, broaden capability, combine renewable power sources, scale back operational prices, scale back dangers to grid operations, and meet regulatory necessities. The answer helps extra than simply the core supervisory management and knowledge acquisition (SCADA) programs, including key use circumstances involving safety of key belongings and energy administration. Its expertise upgrades and community administration capabilities scale back operational prices by decreasing the community footprint and automating key duties. The community infrastructure can assist extra gadgets and deal with extra bandwidth with extra resiliency and new capabilities for the community, akin to time synchronization and internet hosting functions. The Substation Automation answer builds on the visibility and safety of our Grid Safety answer to satisfy the wants of a variety of transmission and distribution substations. The up to date answer helps utilities overcome the next enterprise and operational challenges:

  • Rising variety of course of and station bus gadgets driving greater bandwidth necessities
  • Restricted area and energy in substations for tools
  • Want to scale back cybersecurity dangers by offering visibility into and segmentation of substation gadgets and site visitors flows.
  • Lack of networking expertise in grid operations groups
  • Necessities to Combine and monitor legacy gadgets
  • Regulatory necessities, particularly NERC-CIP and NIS2
  • Must scale to assist extra substations

The Substation Automation answer helps utilities overcome these challenges and lays the muse for extra dependable, sustainable, environment friendly grid operations at a decrease value. Key options of this answer embrace:

  • Extra ports and sooner speeds: Introduction of the IEC 61850-3 and IEEE 1613 compliant Cisco Catalyst IE9300 Rugged Collection Switches with 28 Gigabit Ethernet fiber ports for safe, dependable, low-latency station and course of bus communication
  • Greater port density through stackable switching
  • Better reliability: Assist for a spread of resiliency and synchronization protocols
  • Multifunctional router: Introduction of IEC 61850-3 and IEEE 1613 substation licensed Cisco Catalyst IR8340 Rugged Collection Router and Cisco Catalyst IR1100 Rugged Collection Routers for a mix of scalable WAN connectivity, firewall safety, and software internet hosting
  • Reliability: Assist for a spread of resiliency and synchronization protocols
  • Better safety: Allow extremely safe WAN with superior firewalling, URL filtering, intrusion prevention (IDS/IPS), malware safety, IPsec/MACsec encryption, and DNS safety. Implement community entry management utilizing Cisco Trustsec and IEEE 802.1x. Achieve visibility of substation belongings, their communication actions and your safety posture with Cisco Cyber Imaginative and prescient. Management distant entry into belongings with Cisco Safe Tools Entry. All constructed into Cisco networking tools which have safe boot, signed firmware, and SUDI.
  • Flexibility: Extremely modular platforms to assist switching, routing, synchronization, and edge compute wants
  • Availability: Assist for IEC62439-3 lossless community topologies and protocols (akin to Excessive-Availability Seamless Redundancy [HSR] and Parallel Redundancy Protocol [PRP])
  • Precision: Assist for substation-wide time synchronization (for instance, the 2017 IEEE Precision Time Protocol – Energy Profile or IEC61850-9-3 PUP)
  • Vital capabilities: Assist for substation communications akin to IEC 61850, Modbus, IEC 60870-5-104 (IEC 104) and Distributed Community Protocol 3 (DNP3)
  • Simplicity: Vary of administration choices, together with Cisco Catalyst Middle for substation switching and Cisco SD-WAN Supervisor for SD-WAN routing capabilities

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

Previous to phase routing, multi-protocol label switching (MPLS) packets have been forwarded utilizing label switching as a substitute of IP-based routing, which suggests the routers forwarded site visitors based mostly on the label and never the vacation spot tackle. This required solely the “edge” routers to carry out an IP lookup, whereas intermediate “core” routers carried out solely a label lookup.

Sadly, MPLS didn’t take away complexity from an present community. Actually, it added extra complexity via further protocols and every MPLS node requiring the state to be synchronized throughout the whole community. As the scale of networks grew, so did the state and complexity, making it tougher to function and handle.

Section routing depends on a small variety of extensions to Cisco Intermediate System-to-Intermediate System (IS-IS) and Open Shortest Path First (OSPF) protocols. It could function with an MPLS or an IPv6 knowledge airplane, and it integrates with the wealthy multi service capabilities of MPLS, together with Layer 3 VPN (L3VPN), Digital Personal Wire Service (VPWS), Digital Personal LAN Service (VPLS), and EVPN.

Section routing may be immediately utilized to the MPLS architectures with no change within the forwarding airplane. Section routing makes use of the community bandwidth extra successfully than conventional MPLS networks and presents decrease latency.



EVPN is the following era L2VPN expertise, it gives layer-2 in addition to layer-3 VPN providers in a scalable and simplified method. The evolution of EVPN began because of the want of a scalable answer to bridge numerous layer-2 domains and overcome the restrictions confronted by VPLS akin to scalability, multi-homing, and per-flow load balancing.



Use circumstances thought-about within the new Cisco Validated Designs

We have now 3 classes of providers to think about for the transport community:

  1. Layer 3 IP based mostly Substation to Datacenter: IP based mostly Scada knowledge, IP based mostly CCTV, enterprise knowledge and IP telephony.
  2. Layer 2 Non routable Substation to Substation: Layer 2 ethernet based mostly multicast protocols (akin to IEC61850 GOOSE & SV), Digital machine migrations (for virtualised functions) and third occasion Scada site visitors.
  3. Layer 2 Substation to Substation for Conventional Teleprotection: Energy Safety providers, that are low latency level to level utilizing particular utility protocols and strict engineered paths throughout the community.

SEL Partnership

Cisco companions with Schweitzer Engineering Laboratories to supply the Teleprotection providers and interfaces inside the substation, that are through the SEL ICON platform. This platform gives the interfaces required for substation safety gadgets whereas offering an Ethernet based mostly uplink to the Cisco Converged Transport community (NCS). SEL experience in grid automation is coupled with Cisco’s Industrial substation and converged transport community merchandise gives a better of breed finish to finish answer.
