Introduction to the URPlus-series
Historically, substation protection, control, and metering functions were performed with
electromechanical equipment. This first generation of equipment was gradually replaced
by analog electronic equipment, most of which emulated the single-function approach of
their electromechanical precursors. Both of these technologies required expensive cabling
and auxiliary equipment to produce functioning systems.
Recently, digital electronic equipment has begun to provide protection, control, and
metering functions. Initially, this equipment was either single function or had very limited
multi-function capability, and did not significantly reduce the cabling and auxiliary
equipment required. However, recent digital relays have become quite multi-functional,
reducing cabling and auxiliaries significantly. These devices also transfer data to central
control facilities and human-machine interfaces using electronic communications. The
functions performed by these products have become so broad that many users now prefer
the term IED (Intelligent Electronic Device).
It is obvious to station designers that the amount of cabling and auxiliary equipment
installed in stations can be even further reduced, to 20 to 70% of the levels common in
1990, to achieve large cost reductions. This requires placing even more functions within
the IEDs.
Users of power equipment are also interested in reducing cost by improving power quality
and personnel productivity, and as always, in increasing system reliability and efficiency.
These objectives are realized through software which is used to perform functions at both
the station and supervisory levels. The use of these systems is growing rapidly.
High speed communications are required to meet the data transfer rates required by
modern automatic control and monitoring systems. In the near future, very high speed
communications will be required to perform protection signaling with a performance
target response time for a command signal between two IEDs, from transmission to
reception, of less than 3 milliseconds. This has been established by the IEC 61850 standard.
IEDs with the capabilities outlined above will also provide significantly more power system
data than is presently available, enhance operations and maintenance, and permit the use
of adaptive system configuration for protection and control systems. This new generation
of equipment must also be easily incorporated into automation systems, at both the
station and enterprise levels. The GE Multilin Advanced Universal Protection System
(URPlus-series) has been developed to meet these goals.

CHAPTER 1: GETTING STARTED INTRODUCTION TO THE URPlus-SERIES
D90PLUS LINE DISTANCE PROTECTION SYSTEM – INSTRUCTION MANUAL 3
The D90Plus is the sub-cycle distance protection and advanced automation controller for
the URPlus-series platform.
Hardware architecture
The D90Plus is a microprocessor-based device. It has a modular design consisting of a
chassis containing discrete modules that interface over a common bus. Each module is
dedicated to a specific purpose. Several of the modules are required for basic operation of
the device, while others are optional.
The power supply module receives AC or DC power from an external supply and produces
conditioned 12 V DC power for all of the modules in the chassis. The power supply also
generates 48 V DC power for external contact wetting. The output contact indicating a
critical failure of the unit also resides on this module.
The AC module measures AC currents and voltages derived from CTs and VTs. These
signals are sampled and digitized and sent over the D90Plus bus to the CPU module for
further processing. A version is available that accepts nominal 5 A current and another
that accepts nominal 1 A current.
Input and output modules monitor digital (on and off) signals from external devices (field
contacts or other IEDs), control external devices such as breakers, and send digital signals
to other devices. Input and output modules are subdivided into protection inputs and
outputs and automation inputs and outputs, with several flavors of each type.
The CPU module contains the firmware for the D90Plus. The firmware contains the
algorithms required for the various functions provided by the device. The CPU receives
analog and digital data from the AC and input/output modules. The data is processed by
the CPU and resulting control actions are sent back to the input-output modules. The CPU
has one rear Ethernet port that is used for configuration and record retrieval and one rear
RS485 port supporting the Modbus and DNP protocols. The CPU also contains the IRIG-B
port required for clock synchronization.
The communications module is required for communicating with external devices over
Ethernet using the IEC 61850, DNP 3.0, or IEC60870-5-104 protocols. This module is also
required for peer-to-peer GSSE/GOOSE messaging. This module contains its own
microprocessor which is dedicated to handling communications tasks. It also contains two
redundant Ethernet ports. Each port supports 100Base-FX over multi-mode fiber and 10/
100Base-TX over twisted pair, with auto-negotiation. These ports may additionally be
configured for single IP or dual IP redundancy.
NOTE
NOTE: The D90Plus requires one power supply module, one CPU module, one AC module, and at
least one protection input/output module. Communications modules are optional.
The front panel interface consists of an annunciator display, a main display, and an
EnerVista USB port. The annunciator display collects alarm indications from the
D90Plus internal functions and presents them using a standard annunciator format. Alarms
and their corresponding messages are entirely user-configurable. The main display allows
the user to view metering data collected by the D90Plus. It also provides access to the
control functions via dedicated control pushbuttons. The USB port allows the user to
interface with the D90Plus using the EnerVista software running on a portable PC. The
D90Plus operates independently from the front panel interface.

CHAPTER 1: GETTING STARTED INTRODUCTION TO THE URPlus-SERIES
D90PLUS LINE DISTANCE PROTECTION SYSTEM – INSTRUCTION MANUAL 5
• Digital fault recorder (DFR).
• Equipment manager.
• Front panel interface (HMI).
These functions operate autonomously from one another. Each function has its own
configuration parameters and each generates it own output signals. All functions share
the hardware and the communications facilities within the device.
The protection function contains the necessary elements required to detect faults in the
power system and send tripping signals to isolate the fault. This will be the primary sub-
system for many users. The protection function also has its own dedicated FlexLogic™
engine which runs at the same scan rate as the protection (16 times per power system
cycle). Protection FlexLogic™ is used to create custom logic schemes for protection
purposes.
Automation is divided into two major sub-groupings: control schemes and automation
logic. Control schemes are hard-coded general purpose schemes responsible for
automatic control within the substation. These include breaker and disconnect switch
control, interlocking, and synchrocheck. Automation logic is intended for development of
custom or advanced automatic schemes in the case the user requires a level of
functionality beyond that found in the hard-coded schemes. Automation logic generally
requires a lower execution rate than protection logic but has greatly expanded
functionality and lines of logic.
The metering function generates a wide range of real-time power system measurements
including voltage, current, frequency, complex power, and energy. It also incorporates a
data logger that provides historical recording of selected metering quantities and includes
statistical (maximum, minimum, and average) and alarming capabilities. The metering
function also provides synchrophasor capabilities in accordance with IEEE C37.118-2005.
The digital fault recorder incorporates transient recorder, disturbance recorder and fault
report capabilities. The transient recorder is intended to capture short events such as a
fault at a high sampling rate (up to 256 samples per cycle). The disturbance recorder
captures longer events such as a power swing at a lower sampling rate. The channel
assignments and triggering of these features can be independently configured. The fault
report facility provides a comprehensive record of the key measurements associated with
an event including fault type, fault location, pre-fault and post-fault quantities, and
clearing time.
The equipment manager function monitors important parameters of the station battery
under normal operation and can be used to detect incipient failures.
Despite their logic separation, signals can be exchanged between these functions. For
instance, it is useful for the digital fault recorder to record the output of protection
functions. Consequently a fixed, pre-determined set of signals is available as inputs to
each function. These are illustrated in the following figure.
The D90Plus also includes shared operand functionality. Output signals from the various
functions can be assigned as shared operands available to all functions. These signals can
then be assigned as inputs within other functions.
For example, assume that the PHASE TOC1 OP protection FlexLogic™ operand is required as

D90PLUS LINE DISTANCE PROTECTION SYSTEM – INSTRUCTION MANUAL 7
Figure 4: Communications overview
To communicate through the D90Plus rear RS485 port from a computer’s RS232 port, the
GE RS232/RS485 converter box is required. This device (catalog number F485) connects to
the computer using a straight-through serial cable. A shielded twisted-pair (20, 22, or 24
AWG) connects the F485 converter to the D90Plus rear communications port. The converter
terminals (+, –, GND) are connected to the D90Plus communication module (+, –, COM)
terminals. The line should be terminated with a 120 Ω, 1 nF R-C network.
Communications via Ethernet requires a connection to an Ethernet network using a
standard copper or fiber cable. The Ethernet port can also connect directly to a PC using a
cross-over cable.
To communicate via the faceplate USB port, a standard USB serial cable is used.
For additional information, refer to:
Main processor module on page 50.
EnerVista software
The EnerVista software suite is an industry-leading set of programs that simplifies every
aspect of the D90Plus. The EnerVista suite provides tools to monitor the status of your
protected asset, maintain the relay, and integrate information measured by the
D90Plus into DCS or SCADA monitoring systems. Convenient COMTRADE and sequence of
events viewers are an integral part of the EnerVista URPlus Setup software included with
every D90Plus. This allows the user to carry out post-mortem event analysis to ensure
proper protection system operation.
