One might think scale can be resolved by adding more equipment into the infrastructure. For utilities that need more time before they can migrate the substation implementation to Cisco and IEC based standards, a few legacy resiliency protocols are available to choose from within ring topology deployments:. The management plane is used to access, configure, and manage a device, as well as monitor its operations and the network on which it is deployed. Communication Bus. IEC defines how data is represented but does not define what function or data is available in any particular type of IED. This section assumes that the Cisco IE switch has been installed and pre-configured with an IP address for remote access. Orlando is a utility automation consultant with Power System Engineering Inc. Legacy Resiliency Protocols Depending on whether or not a utility decides to fully embrace IEC design recommendations, several resiliency protocols are available from which to choose. Substation Automation Local Area Network and Security Preface Cisco is committed to providing a holistic substation automation solution that implements a scalable, secure, and resilient multiservice-enabled network. GOOSE is one of the IEC traffic types within the substation that is time sensitive in nature and requires low-latency forwarding.

  • PDF | The automation of control systems of substations in the energy industry uses a variety of specialized standards, technologies and protocols. Among the. Index Terms—Communication. Substation Automation. Protocols. IEC Substation Automation is one of the key areas of Power. Systems. It enables electric utility to remotely For example data “Pos” of data class type “DPC” is a member of.

    Communication protocols and standards were Introduced in 's to industry implementing substation automation (SA) systems. The main features of. Communications. ▫ Example: employ GOOSE messaging concept for.
    There are two choices:. For example, a recent change with DNP3 is that, by the end ofall devices will be required to return timestamps in UTC coordinated universal time format.

    For example, to restrict traffic at an ingress interface, policing should be used. Native support available on IEDs. Detecting network anomalies as soon as possible gives operations teams the means to remediate network abnormality sooner, thereby reducing possible downtimes.

    GOOSE is one of the IEC traffic types within the substation that is time sensitive in nature and requires low-latency forwarding.

    Where possible, an out-of-band network for network management should be deployed.

    The choice of the tool depends on traffic types. With a proper QoS configuration to protect real-time, latency sensitive traffic, latency and jitter should not be a problem as long as traffic stays inside the Layer 2 ESP zone. Like its predecessor, RSTP creates spanning-tree instances.

    Note: Reload the switch for the change to take effect.

    paper discusses the evaluation of IEC communication protocol, the standard for '“Communication Networks Keywords: Communication, substation automation systems. is based on abstracting the definition of the data items.

    Security risk assessments identify control systems and their level of criticality.

    This allows a shared infrastructure to carry zone traffic over common physical but logically separated networks. Challenge 4—Security The forth challenge is to design for security.

    Low Speed. Industry Needs. For example, to restrict traffic at an ingress interface, policing should be used. This traffic flows normally on the process bus but can also flow over the station bus, for instance, for busbar protection and phasor measurement.

Communication model in previewed protocols [16] • Data definition based on. Today, a substation can have numerous communication protocols Some examples of what communications to a substation could involve today include: IECcommunication networks and systems in substations.
    Interface Mapping.

    Inthe last of the 10 parts of IEC became an international standard. In on-line mode, the master station will receive this data via the file transfer function of DNP3. Each of these applications impact the communications network, cyber security needs, plans and designs for substation equipment, and head-end software applications.

    This zone is the least secure zone and includes devices and services such as IP phones, video end points, and Wi-Fi connected or hardwired PCs for corporate applications.

    It can also be configured using the following command:.

    An intelligent communications network is a foundation to building a smart grid. Each deployment may incorporate variations on the recommended prioritization. This document intends to make a case for moving forward with Ethernet in substations, since Ethernet can be used to help build an intelligent, easy-to-maintain, flexible, and cost-effective alternative to hard-wired and serial-based substation deployments.

    In this mode, the switch participates in the selection of the most accurate master clock. Cloud-Fog-Edge for Utilities: Successful digital business transformation requires putting computing power where it's needed.

    5 thoughts on “Substation automation system communication protocol examples

    1. Assign PRP channel to the physical interface. The DMZ firewall at the substation edge helps provide controlled access into substations.

    2. A dying gasp is a notification message which signifies a critical event, such as loss of power or a link going down. Have you analyzed the bandwidth consumption once application traffic is enabled?

    3. Storm control, a Layer 2 network security protocol, prevents traffic on a LAN from being disrupted by a broadcast, multicast, or unicast storm on one of the physical interfaces. With HSR and PRP resiliency protocols, Cisco recommends protecting the network from storms as they can very quickly multiply even faster considering the packet replication that occurs by applying a redundancy feature.
