DEVICE OVERVIEW CHAPTER 2: PRODUCT DESCRIPTION
The protection system consists of a distributed process interface (data acquisition and
tripping) architecture using GE HardFiber
the B95
The functions of the B95
Plus
.
Plus
include the following:
Bricks, with centralized processing performed by
• Multi-zone differential protection with both restrained (dual-slope percent or biased)
and unrestrained (unbiased or instantaneous) functions incorporated. Differential
protection is fast and secure. Security is achieved by using a reliable current
transformer (CT) saturation detection algorithm and a directional comparison
operating principle. Security is further enhanced by support for redundant process
interface (Bricks). Three-phase tripping is supported; differential protection operands
are provided for individual phase tripping.
• Interfaces with up to eight HardFiber Bricks per process card. The B95
Plus
can contain
one or two process cards.
• Supports up to 12 bus sources per process card. A single bus source is used to
interface a network element connection to the bus, such as a feeder, line, transformer,
capacitor, or reactor. A single bus source is used to interface a bus tie disconnect. Two
bus sources are used to interface a bus tie breaker.
• Dynamic bus replica functionality and multi-zone protection is supported allowing
application of the B95
Plus
to multi-section reconfigurable buses. A zone expansion/
contraction to an open breaker feature is included.
• Check-zone functionality can be configured by programming one of the differential
zones to enclose the entire bus.
• Supports up to two undervoltage functions per process card for differential protection
supervision purposes.
• End-fault protection (dead-zone protection) is provided for each bus source.
• A breaker fail function with three-phase tripping support and fast resetting current
detectors is provided for each bus source.
• An instantaneous phase overcurrent function is provided for each bus source for
possible supervision purposes.
• An inverse time phase overcurrent function is provided for each bus source for
possible backup protection.
• An isolator position resolution and monitoring feature monitors 48 isolators per
process card.
• A CT trouble monitoring function is provided for each zone of differential protection.
Voltage and current metering are built into the relay as standard features, as fundamental
frequency-only root mean square (RMS) scaled magnitude and angle (phasor).
Diagnostic features include an event recorder capable of storing 4,096 time-stamped
events plus 4,096 time-stamped events per process card. Oscillography is userprogrammable as to sampling rate (up to 128 samples per cycle), content, writing mode,
and record length. The internal clock used for time stamping can be synchronized with an
IRIG-B signal or using the simple network time protocol (SNTP) over Ethernet. This precise
time stamping allows the sequence of events to be determined throughout the system.
Events can also be programmed using FlexLogic
TM
equations to trigger oscillography data
capture, which can be set to record the measured parameters before and after the event
for viewing on a computer. These tools significantly reduce troubleshooting time and
simplify report generation in the event of a system fault.
On the communications card, either of the two Ethernet ports can be used for supervisory
control and data acquisition (SCADA) access, the programming of settings, and the
monitoring of actual values. These two Ethernet ports have both 100Base-TX and
4 MULTILIN B95

CHAPTER 2: PRODUCT DESCRIPTION DEVICE OVERVIEW
100Base-FX interfaces, and they can be used to provide fast, reliable communications in
noisy environments. These ports support TFTP, SNTP, IEC 61850, Modbus/TCP, and IEC
60870 protocols. DNP 3.0 and IEC 60870 cannot be enabled at the same time.
A third Ethernet port supports engineering access using the EnerVista B95

Advanced functionality allows the user to access comprehensive information without
having to navigate through conventional displays and keypads. Information displays on
two graphical display panels on the front panel. One serves as a digital annunciator and
the other, called the HMI, displays mimic diagrams, phasor plots, and other information.
The configurable, color LCD annunciator on the front panel eliminates the need for LEDs
and separate annunciator devices. Any contact input, remote input, or internally
generated logic operand can be assigned to each indicator, as well as any analog
operand. Up to 288 indicators can be assigned. The display can be configured for 12, 24, or
48 indicators per page. A separate self-test message page on the annunciator panel
displays error messages about device health.
The HMI panel provides easy access and visualization of device information, ranging from
the graphical and numeric display of bus source current phasors, voltage source phasors,
differential and restraint phasors, and tracking frequency, as well as a display of sequence
of events and a transient records list. The HMI can display a mimic diagram that provides
the status of each bus source’s breaker and isolators. Many bay configurations can be
realized through the setting of the device.

CHAPTER 2: PRODUCT DESCRIPTION HARDFIBER OVERVIEW
HardFiber overview
The GE HardFiber Process Bus System allows copper wiring to be replaced in substation
switchyards with optical fiber. The system includes all physical components required for its
installation: relays; factory pre-terminated fiber cables; fiber crossconnect panels; factory
connectorized copper cables; and switchyard I/O interface devices known as Bricks. The
Bricks implement the concept of an IEC 61850 merging unit, expanded to optically connect
relays with all types of input and output signals in the switchyard, not just instrument
transformers. The relays are the proven GE Multilin Universal Relay (UR) series devices with
a decade-long field record, and they incorporate all major applications from a simple
feeder relay to a sophisticated generator protection package. With the release of the
Plus
, the HardFiber system can also be used for the protection of large and dynamic
B95
buses.
Figure 3: GE HardFiber Brick top view
The HardFiber system replaces copper wiring between power apparatus in the switchyard
and protection and control devices in the control house with off-the-shelf components that
use standard physical and logical interfaces. As such, it shortens deployment time, reduces
labour requirements, facilitates work transfer, improves quality, simplifies procurement,
and improves safety.
