The Cisco Substation Automation answer permits utilities to help new enterprise fashions, develop capability, combine renewable vitality sources, cut back operational prices, cut back dangers to grid operations, and meet regulatory necessities. The answer helps extra than simply the core supervisory management and information acquisition (SCADA) techniques, including key use circumstances involving safety of key property and energy administration. Its expertise upgrades and community administration capabilities cut 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, similar to time synchronization and internet hosting purposes. The Substation Automation answer builds on the visibility and safety of our Grid Safety answer to fulfill 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 units driving increased bandwidth necessities
Restricted house and energy in substations for gear
Want to cut back cybersecurity dangers by offering visibility into and segmentation of substation units and 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 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 embody:
Extra ports and quicker 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 by way of stackable switching
Larger 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 utility internet hosting
Reliability: Assist for a spread 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. Achieve 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 Tools Entry. All constructed into Cisco networking gear which have safe boot, signed firmware, and SUDI.
Flexibility: Extremely modular platforms to help switching, routing, synchronization, and edge compute wants
Availability: Assist for IEC62439-3 lossless community topologies and protocols (similar 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 similar 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 Heart for substation switching and Cisco SD-WAN Supervisor for SD-WAN routing capabilities
Evolution to section routing and Ethernet VPN (EVPN) for substation WAN connectivity
Previous to section routing, multi-protocol label switching (MPLS) packets had been forwarded utilizing label switching as a substitute of IP-based routing, which suggests the routers forwarded visitors primarily based 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 the whole community. As the dimensions of networks grew, so did the state and complexity, making it harder 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 information 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 might 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
EVPN is the following era L2VPN expertise, it supplies layer-2 in addition to layer-3 VPN providers in a scalable and simplified method. The evolution of EVPN began as a result of want of a scalable answer to bridge varied layer-2 domains and overcome the constraints confronted by VPLS similar to scalability, multi-homing, and per-flow load balancing.
Use circumstances thought-about within the new Cisco Validated Designs
We’ve 3 classes of providers to contemplate for the transport community:
Layer 3 IP primarily based Substation to Datacenter: IP primarily based Scada information, IP primarily based CCTV, enterprise information and IP telephony.
Layer 2 Non routable Substation to Substation: Layer 2 ethernet primarily based multicast protocols (similar to IEC61850 GOOSE & SV), Digital machine migrations (for virtualised purposes) and third get together Scada visitors.
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 by way of the SEL ICON platform. This platform supplies the interfaces required for substation safety units whereas offering an Ethernet primarily based 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 supplies a better of breed finish to finish answer.
