The Cisco Substation Automation resolution allows utilities to help new enterprise fashions, broaden capability, combine renewable vitality 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 property 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 help extra units and deal with extra bandwidth with extra resiliency and new capabilities for the community, comparable to time synchronization and internet hosting purposes. The Substation Automation resolution builds on the visibility and safety of our Grid Safety resolution to fulfill the wants of a variety of transmission and distribution substations. The up to date resolution helps utilities overcome the next enterprise and operational challenges:

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

The Substation Automation resolution helps utilities overcome these challenges and lays the muse for extra dependable, sustainable, environment friendly grid operations at a decrease price. Key options of this resolution 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
  • Increased port density through stackable switching
  • Larger reliability: Help for a variety 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 utility internet hosting
  • Reliability: Help for a variety of resiliency and synchronization protocols
  • Larger 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. Acquire visibility of substation property, their communication actions and your safety posture with Cisco Cyber Imaginative and prescient. Management distant entry into property with Cisco Safe Gear Entry. All constructed into Cisco networking tools which have safe boot, signed firmware, and SUDI.
  • Flexibility: Extremely modular platforms to help switching, routing, synchronization, and edge compute wants
  • Availability: Help for IEC62439-3 lossless community topologies and protocols (comparable to Excessive-Availability Seamless Redundancy [HSR] and Parallel Redundancy Protocol [PRP])
  • Precision: Help for substation-wide time synchronization (for instance, the 2017 IEEE Precision Time Protocol – Energy Profile or IEC61850-9-3 PUP)
  • Crucial features: Help for substation communications comparable 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 an alternative 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 current community. In actual fact, it added extra complexity via extra protocols and every MPLS node requiring the state to be synchronized throughout all the 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 actually function with an MPLS or an IPv6 knowledge aircraft, and it integrates with the wealthy multi service capabilities of MPLS, together with Layer 3 VPN (L3VPN), Digital Non-public Wire Service (VPWS), Digital Non-public LAN Service (VPLS), and EVPN.

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



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



Use circumstances thought-about within the new Cisco Validated Designs

We’ve got 3 classes of companies 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 (comparable to IEC61850 GOOSE & SV), Digital machine migrations (for virtualised purposes) and third celebration Scada site visitors.
  3. Layer 2 Substation to Substation for Conventional Teleprotection: Energy Safety companies, 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 companies and interfaces inside the substation, that are through the SEL ICON platform. This platform offers the interfaces required for substation safety units 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 offers a better of breed finish to finish resolution.
