    • President, SUBNET Solutions Inc.

    • Former President, DNP3 User Group

    • Canada

  • We have many different IEDs and BI Systems deployed to meet different department needs

    The Situation Today

  • Deploy many more IEDs and integrate them intelligently to new BI Systems and realize many new Smart Grid Benefits

    The “Smarter” Grid Tomorrow – The Reward?

  • Without good standards, this has created a complexity that has become unmanageable.

    The “Smarter” Grid Tomorrow – The Reward?

  • Substation Integration complexity today is more than just Protocol Translation

    • SCADA and Non-SCADA data substation communications

    • Fault File Management

    • Remote Engineering Access (CIP-005, CIP-007)

    • Password Change Management (CIP-005, CIP-007)

    • Configuration Management (CIP-010)

  • IEC-61850 Marketed Promise

    • IEC-61850 had been marketed for approximately 15 years as the Electric Utility answer for….

    – Multi-vendor Interoperability

    – Reducing IED Integration complexity

    • Self Description, etc

    – Enabling engineering efficiencies

    • Configuration

    • Testing

  • Presentation Overview

    • This presentation outlines recent history of the state of IEC-61850 Interoperability

    – Review Results from Recent IEC-61850 IOPs

    – Review Issues and Solutions for a Major Multi-Vendor IEC-61850 Utility Project

    – Discusses vendor business cases “for” and “against” effective Multi-Vendor IEC-61850 Interoperability

  • Using IEC 61850 was supposed to assist with this complexity

  • Single Vendor IEC 61580 Interoperability = OK

    • Issues found between vendor files – Incorrect initialized values. – Issues found between vendor implementations

    • Support of Integer 128 issues – Inability to “to map/support such a value in the implementations

    memory/application”

    – “Vendor A attempted to import an SCD file exported by Vendor B. A problem occurred. The problem was diagnosed to be an unsupported XML Namespace issue”

    – “Engineering efforts required to implement the standard in a substation are huge”

    – “Grid operators are forced to use specific vendor tools that are not optimal in a multi-vendor environment and train staff to use a wide range of tools to configure the system”

    – “A clear move by the market to a top-down approach using standardized third-party tools is needed”

  • IEC 61850 IOP 2013

  • IEC 61850 IOP 2013

    • 61850 Standard Issues from the report:

    – SCL

    • “ED.1/ED.2 co-existence in a single SCD file”

    • “Client reporting subscription”

    • “GOOSE subscription”

    • “SV subscription”

    – Networking

    • “VLAN Tag 0 support in switches”

  • Incorrect SCD/CID File Formats

    • CIGRE 2014:

    – Issues with Major Relay Vendor CID files

    • Problem: Vendor tools create incorrect CID file formats – Issue: Found several instances of missing DOType, DAType,

    ENUM, and ConnectedAP definitions

    – Issue: Point IDs created to be too long and incompatible with certain 61850 server driver implementations

  • Incorrect SCD/CID File Formats

    • Problem: Vendor tools used to integrate CIDs into an SCD file don’t properly handle object types with the same name in each CID. This causes conflicts and redefining definitions. – Example: Each CID defines its own DOType called A. What DOType definition is used in

    the SCD?

    SCD File

    CID DOType = A DAType 1 DAType 2

    CID DOType = A DAType 1 DAType 2

    DAType 3

    CID DOType = A DAType 1

    CID CID CID

    DOType = A?

  • Incorrect SCD/CID File Formats

    • Solution: Vendor enhancement requests

    SCD File

    CID_1 DOType = A DAType 1 DAType 2

    CID_2 DOType = A DAType 1 DAType 2

    DAType 3

    CID_3 DOType = A DAType 1

  • Result of IEC-61850 Issues

    • Many Utilities concerned about doing their own integration

    • Many seek turnkey integration solutions for device Vendor

    • Device Vendors get to supply Single Vendor solutions vs Multi-Vendor

    • Bottom Line: Ongoing Vendor Specific issues hurt Utilities, help Device Vendors

  • IED Vendors Smart Grid Business Case for Profit Maximization

    IED Vendors Integration Goals

    • Buy more of their IEDs

    • Buy newer, more expensive IEDs

    • Upgrade, Replace IEDs more Frequently

    IED Vendor Specific Integration Solutions

    • Buy more of their IEDs vs others

    • Add new basic IT functionality into edge IEDs vs upper tier devices

    • Accelerate product discontinuance, obsolescence

  • Multi-Vendor IEC 61850 is still possible however…

  • Southern California Edison Irvine Smart Grid Demonstration

    “The project will demonstrate the next generation of automation and control design based on the open standard IEC-61850.

    This is expected to provide measurable engineering, operations, and maintenance benefits through improved safety, security, and reliability.

    Demonstration of a new auto-configuration application is intended to significantly reduce manual effort, errors, and omissions.”

  • The Configuration Management, Password Management, and Remote Engineering Access Management need to be integrated.

    Using IEC 61850 for Enterprise Management

  • You can’t keep passwords a secret if every time someone uses your remote engineering access

    system, they need the password.

    Integrated Solution

  • Password Management and Remote Engineering Access need to be integrated.

    Integrated Solution

  • The same is true with configuration management. If the system is to provide automation of these functions, it needs to be able to logon to the device at an authorized privilege level. This requires both remote

    engineering access and the device passwords.

    Integrated Solution

  • The Configuration Management, Password Management, and Remote Engineering Access Management need to be

    integrated.

    Integrated Solution

  • The solution needs to be vendor-agnostic.

    Integrated Solution

  • What functions are we looking for?

    • Version-control

    • Permission policies

    • Approval processes and workflow

    • Change Notifications

    Configuration Management (CIP-010)

  • IEC-61850 Defines a Standards-Based Approach to Configurations with SCL.

    Based on Standards

  • A vast array of tooling and technology can be leveraged for working with the information.

    SCL Files are XML

  • The CID schema can be extended for defining legacy devices (Modbus, DNP3, etc.) within the context of IEC-61850. The CID schema can be extended to support equipment such as routers and switches.

    SCL Files are Extensible

  • IEC-61850 SCL helps us with… • considering all device

    configurations as one holistic substation configuration.

    • differencing two different configuration files.

    • Ensuring compatibility with legacy devices.

    • considering the IT devices (routers, switches, and radios) the same at the OT devices.

    • Leveraging open standards.

    Solving part of the problem

  • Our corporate and substation-level architecture can help with the rest.

    • Synchronization between the corporate environment and the substation.

    • actively monitoring the devices in the substation.

    • Automatically extracting changed configurations from devices.

    Solving the other part of the problem

  • The system starts with the building of a Substation Configuration Description file (.SCD) by a “Substation

    Engineering Modelling Tool”.

    The SCD describes the entire substation configuration, including every IED, HMI, network switch, and router.

    3. Transfer of SCD File to Substation Gateway

  • Configuring the substation gateway:

    • Automatically create all substation devices.

    • Automatically build point references.

    • Establish which end devices have configurations ready to be deployed.

  • In summary…

    • Integration solutions from device vendors benefit from Multi-vendor Interoperability issues as they maximize revenue when he sells a their Single Vendor solution

    • However effective IEC 61850 Multi-Vendor Integration is possible

    • IEC-61850 Interoperability issues can be resolved by companies focused on providing true Multi-vendor solutions
