Read this chapter to help guide you through the initial setup of your new G30 Generator Protection System.
1.1.1 CAUTIONS AND WARNINGS
Before attempting to install or use the device, review all safety indicators in this document to help prevent injury, equipment
damage, or downtime.
The following safety and equipment symbols are used in this document.
Indicates a hazardous situation which, if not avoided, will result in death or serious injury.
Indicates a hazardous situation which, if not avoided, could result in death or serious injury.
Indicates a hazardous situation which, if not avoided, could result in minor or moderate
injury.
Indicates practices not related to personal injury.
a) GENERAL CAUTIONS AND WARNINGS
The following general safety precautions and warnings apply.
Ensure that all connections to the product are correct so as to avoid accidental risk of shock

1.2UR OVERVIEW 1.2.1 INTRODUCTION TO THE UR
Historically, substation protection, control, and metering functions were performed with electromechanical equipment. This
equipment was gradually replaced by analog equipment, most of which emulated the single-function approach of their elec-
tromechanical precursors. Both 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 equip-
ment was either single function or had very limited multifunction capability, and it did not significantly reduce the cabling and
auxiliary equipment required. However, recent digital relays are multifunctional, reducing cabling and auxiliaries signifi-
cantly. These devices also transfer data to central control facilities and software using electronic communications. The
functions performed have become so broad that many users now prefer the term Intelligent Electronic Device (IED).
It is obvious to station designers that the amount of cabling and auxiliary equipment installed can be even further reduced,
to 20% to 70% of levels common in 1990, and 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
in increasing system reliability and efficiency. These objectives are realized through software that is used to perform func-
tions at both the station and supervisory levels. The use of these systems is growing rapidly.
High-speed communication is required to meet the data transfer rates required by modern automatic control and monitoring
systems. Very high speed communications are 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 such capabilities also provide significantly more power system data than was available, enhanced operations and
maintenance, and permit the use of adaptive system configuration for protection and control systems. This new generation
of equipment is easily incorporated into automation systems, at both the station and enterprise levels. The GE Multilin Uni-
versal Relay (UR) series meets these goals.
1.2.2 HARDWARE ARCHITECTURE
a) UR BASIC DESIGN
The UR is a digital-based device containing a central processing unit (CPU) that handles multiple types of input and output
signals. The UR device can communicate over a local area network (LAN) with an operator interface, a programming
device, or another UR device.
Figure 1–2: UR CONCEPT BLOCK DIAGRAM
The CPU module contains firmware that provides protection elements in the form of logic algorithms, as well as program-
mable logic gates, timers, and latches for control features.

1.2 UR OVERVIEW 1 GETTING STARTED

Input elements accept a variety of analog or digital signals from the field. The UR isolates and converts these signals into
logic signals used by the relay.
Output elements convert and isolate the logic signals generated by the relay into digital or analog signals that can be used
to control field devices.
b) UR SIGNAL TYPES
The contact inputs and outputs are digital signals associated with connections to hard-wired contacts. Both ‘wet’ and ‘dry’
contacts are supported.
The virtual inputs and outputs are digital signals associated with UR-series internal logic signals. Virtual inputs include
signals generated by the local user interface. The virtual outputs are outputs of FlexLogic™ equations used to customize
the device. Virtual outputs can also serve as virtual inputs to FlexLogic equations.
The analog inputs and outputs are signals that are associated with transducers, such as Resistance Temperature Detec-
tors (RTDs).
The CT and VT inputs refer to analog current transformer and voltage transformer signals used to monitor AC power lines.
The UR-series relays support 1 A and 5 A CTs.
The remote inputs and outputs provide a means of sharing digital point state information between remote UR-series
devices. The remote outputs interface to the remote inputs of other UR-series devices. Remote outputs are FlexLogic oper-
ands inserted into IEC 61850 GSSE and GOOSE messages.
The direct inputs and outputs provide a means of sharing digital point states between a number of UR-series IEDs over a
dedicated fiber (single or multimode), RS422, or G.703 interface. No switching equipment is required as the IEDs are con-
nected directly in a ring or redundant (dual) ring configuration. This feature is optimized for speed and intended for pilot-
aided schemes, distributed logic applications, or the extension of the input/output capabilities of a single relay chassis.
c) UR SCAN OPERATION
The UR-series devices operate in a cyclic scan fashion. The device reads the inputs into an input status table, solves the
logic program (FlexLogic equation), and then sets each output to the appropriate state in an output status table. Any result-
ing task execution is priority interrupt-driven.

1.2.3 SOFTWARE ARCHITECTURE
The firmware (software embedded in the relay) is designed in functional modules that can be installed in any relay as
required. This is achieved with object-oriented design and programming (OOD/OOP) techniques.
Object-oriented techniques involve the use of objects and classes. An object is defined as “a logical entity that contains
both data and code that manipulates that data”. A class is the generalized form of similar objects. By using this concept,
one can create a protection class with the protection elements as objects of the class, such as time overcurrent, instanta-
neous overcurrent, current differential, undervoltage, overvoltage, underfrequency, and distance. These objects represent
completely self-contained software modules. The same object-class concept can be used for metering, input/output control,
software interface, communications, or any functional entity in the system.
Employing OOD/OOP in the software architecture of the G30 achieves the same features as the hardware architecture:
modularity, scalability, and flexibility. The application software for any UR-series device (for example, feeder protection,
transformer protection, distance protection) is constructed by combining objects from the various functional classes. This
results in a common interface across the UR series.
1.2.4 IMPORTANT CONCEPTS
As described above, the architecture of the UR-series relays differ from previous devices. To achieve a general understand-
ing of this device, some sections of Chapter 5 are quite helpful. The most important functions of the relay are contained in
“elements”. A description of the UR-series elements can be found in the Introduction to elements section in chapter 5.
Examples of simple elements, and some of the organization of this manual, can be found in the Control elements section of
chapter 5. An explanation of the use of inputs from CTs and VTs is in the Introduction to AC sources section in chapter 5. A
description of how digital signals are used and routed within the relay is contained in the Introduction to FlexLogic section in
chapter 5.
