LAN Redundancy

Substation LAN redundancy has been

traditionally accomplished by reconfiguring

the active network topology in case of failure.

Regardless of the type of LAN architecture (tree,

mesh, etc), reconfiguring the active LAN requires

time to switchover, during which the LAN is

unavailable. UR devices deliver redundancy as

specified by PRP-IEC 62439-3. which eliminates

the dependency on LAN reconfiguration and the

associated switchover time. The UR becomes a

dual attached node that transmits data packets

over both main and redundant networks

simultaneously, so in case of failure, one of the

data packets will reach the receiving device with

no time delay.

Multi-Language

UR devices support multiple languages: English,

French, Russian, Chinese, Turkish and German.

These language options are available on the

front panel, in the EnerVista setup software, and

in the product manuals. Easily switch between

English and an additional language on the local

displays without uploading new firmware.

Direct I/O Messaging

Direct I/O allows for the sharing of high-speed

digital information between multiple UR

relays via direct back-to-back connections or

multiplexed through a standard DS0 multiplexer

channel bank. Regardless of the connection

method, direct I/O provides continuous real-time

channel monitoring that supplies diagnostics

information on channel health.

Direct I/O provides superior relay-to-relay

communications that can be used in advanced

interlocking, generation rejection and other

special protection schemes.

• Communication with up to 16 UR relays

in single or redundant rings rather than

strictly limited to simplistic point-to-point

configurations between two devices

• Connect to standard DS0 channel banks

through standard RS422. G.703 or IEEE

C37.94 interfaces or via direct fiber optic

connections

• No external or handheld tester required to

provide channel diagnostic information

Interoperability with Embedded IEC

61850 Edition 2

The new IEC 61850 implementation in the UR

Family positions GE as an industry leader in this

standard:

• Implements Edition 2 of the standard across

the entire family of UR devices

• Provides full relay setting management via

standard SCL files (ICD, CID and IID)

• Enables automated relay setting

management using 3rd party tools through

standard file transfer services (MMS and SFTP)

• Increases the number of Logical Devices and

data mapped to them, GOOSE messages, and

reports to support different organizational

needs for data transfer and reduce

dependency on generic logical nodes

• Configures GE Systems based on IEC 61850

using universal 3rd party tools

Cyber Security –

CyberSentry UR

CyberSentry UR enabled UR devices deliver full

cyber security features that help customers to

comply with NERC CIP and NIST® IR 7628 cyber

security requirements.

wThis software option delivers the following core features:

AAA Server Support (Radius/LDAP)

Enables integration with centrally managed

authentication and accounting of all user

activities and uses modern industry best

practices and standards that meet and exceed

NERC CIP requirements for authentication and

password management.

Role Based Access Control (RBAC)

Efficiently administrate users and roles within

UR devices. The new and advanced access

functions allow users to configure up to five

roles for up to eight configurable users with

independent passwords. The standard “Remote

Authentication Dial In User Service” (Radius) is

used for authentication.

Event Recorder (Syslog for SEM)

Capture all cyber security related events within

a SOE element (login, logout, invalid password

attempts, remote/local access, user in session,

settings change, FW update, etc), and then

serve and classify data by security level using

standard Syslog data format. This will enable

integration with established SEM (Security Event

Management) systems.

Monitoring and Metering

The C30 provides high resolution measuring

of the status of external devices wired to its

contact inputs. The changing of a contact input

status can be measured

and time-stamped with a 0.5ms resolution,

making the C30 ideal for bay or substation SOE

recording.

Fault and Disturbance Recording

The advanced disturbance and event recording

features within the C30 can significantly reduce

the time needed for postmortem analysis

of power system events and the creation of

regulatory reports.

Advanced Device Health Diagnostics

The C30 performs comprehensive device health

diagnostic tests at startup and continuously

during run-time to test its own major functions

and critical hardware. These diagnostic tests

monitor for conditions that could impact security

and availability of protection, and present device

status via SCADA communications and front

panel display. Providing continuous monitoring

and early detection of possible issues help

improve system uptime.

Multilin™ C30

Substation Hardened Programmable

Logic Controller

The Multilin C30 controller system is a substation hardened device designed to perform substation

control logic that can also expand the I/O capability of protection devices and replace existing SOE

recorders. The C30 provides fast and deterministic execution of programmable logic with I/O capabilities

far above an average protection relay.

Graphical programming tools, supported by a library of logic operators, make the C30 simple to use

and configure. Using high-speed peer-to-peer communications for inter-device messaging, the C30 can

also accept signals and commands from other protection and control devices at a fraction of the cost

of hard-wiring these signals.

Key Benefits

• Powerful and deterministic programmable logic suitable for creating most customized automated

substation control solutions

• Modular hardware architecture allowing for flexibility in the I/O configuration to support most bay

management applications

• Reduced bay or station wiring through the use of high-speed peer-to-peer communication for sending

and accepting control commands from other relays

• Simplified system integration and access to information through the use of multiple communication

options and protocols not found in industrial grade PLCs

• Advanced IEC 61850 Ed. 2 implementation, complete settings via SCL files and IEC 61850-9-2 process

bus solution enable resource and platform managing optimization and reduce cost of ownership

• Increased network availability via failover time reduced to zero through IEC® 62439-3 “PRP” support

• CyberSentry™ provides high-end cyber security aligned to industry standards and services (NERC® CIP,

AAA, Radius, RBAC, Syslog)

• Advanced fault and disturbance recording, including internal relay operating signals, eliminating the

need for external recording devices

Conclusion

CT/VT modules with enhanced diagnostics, released on 23 October 2006 with firmware 5.2.

offer much higher security for internal CT/VT module error detection and prevent undesired operations of URs.

Every UR firmware released since version 5.2 supports CT/VT modules with enhanced diagnostics,

which greatly improves the security and reliability of the protection system.

To take advantage of this feature, a relay hardware and possibly firmware upgrade is required.

If the existing relay has a firmware version below 4.0. GE recommends purchasing a

UR Upgrade Kit that allows modernization of the obsolete relay hardware

while taking advantage of the relay modularity.

The UR Upgrade Kit contains a new CPU and CT/VT modules that can be

inserted in an existing relay case (case is fully backwards compatible).

If the relay currently has firmware version 4.0 to 5.0. the latest firmware

can be downloaded from the GE Multilin website, and Enhanced Diagnostic

CT/VT modules (8L, 8M, 8N, 8R, 8S, 8V) can be purchased from the GE Online Store.

Consult with your local GE representative if you have any questions on the upgrade process.
