1.1 This manualThe application manual contains application descriptions and setting guidelines

sorted per function. The manual can be used to find out when and for what purpose

a typical protection function can be used. The manual can also be used when

calculating settings.

1.2 Intended audienceThis manual addresses the protection and control engineer responsible for

planning, pre-engineering and engineering.

The protection and control engineer must be experienced in electrical power

engineering and have knowledge of related technology, such as communication

and protocols.

Figure 1: The intended use of manuals in different lifecycles

The engineering manual contains instructions on how to engineer the IEDs using

the different tools in PCM600. The manual provides instructions on how to set up a

PCM600 project and insert IEDs to the project structure. The manual also

recommends a sequence for engineering of protection and control functions, LHMI

functions as well as communication engineering for IEC 60870-5-103, IEC 61850and DNP3.

The installation manual contains instructions on how to install the IED. The

manual provides procedures for mechanical and electrical installation. The chapters

are organized in chronological order in which the IED should be installed.

The commissioning manual contains instructions on how to commission the IED.

The manual can also be used by system engineers and maintenance personnel for

assistance during the testing phase. The manual provides procedures for checking

of external circuitry and energizing the IED, parameter setting and configuration as

Section 1 1MRK 502 033-UEN -Introduction

well as verifying settings by secondary injection. The manual describes the process

of testing an IED in a substation which is not in service. The chapters are organized

in chronological order in which the IED should be commissioned.

The operation manual contains instructions on how to operate the IED once it hasbeen commissioned. The manual provides instructions for monitoring, controlling

and setting the IED. The manual also describes how to identify disturbances and

how to view calculated and measured power grid data to determine the cause of a

fault.

The service manual contains instructions on how to service and maintain the IED.

The manual also provides procedures for de-energizing, de-commissioning and

disposal of the IED.

The application manual contains application descriptions and setting guidelines

sorted per function. The manual can be used to find out when and for what purpose

a typical protection function can be used. The manual can also be used when

calculating settings.

The technical manual contains application and functionality descriptions and lists

function blocks, logic diagrams, input and output signals, setting parameters and

technical data sorted per function. The manual can be used as a technical reference

during the engineering phase, installation and commissioning phase, and during

normal service.

The communication protocol manual describes a communication protocol

supported by the IED. The manual concentrates on vendor-specific implementations.

The point list manual describes the outlook and properties of the data points

specific to the IED. The manual should be used in conjunction with the

corresponding communication protocol manual.

The service manual is not available yet.

understand that under certain operational conditions, operation of damaged

equipment may result in degraded process performance leading to personal injury

or death. Therefore, comply fully with all warning and caution notices.

Section 2 Application

2.1 REG650 applicationREG650 is used for the protection and monitoring of generating plants. The IED is

especially suitable for applications in distributed control systems with high

demands on reliability. It is intended mainly for small and medium size generation

stations.

REG670 may be used when more extensive protection systems are required or in

combination with REG650 to provide redundant schemes.

A wide range of protection functions is available to achieve full and reliable

protection for different types of generating plants, for example hydro power plants

and thermal power plants. This enables adaptation to the protection requirements of

most generating plants.

Protection functions are available for detecting and clearing internal faults, such as

generator stator short circuits and earth faults, generator rotor earth faults, unit

transformer short circuits and earth faults and faults in the external power system,

fed from the generating plant.

Two packages have been defined for the following applications:

Generator protection IED including generator differential protection (B01)

Generator-transformer unit protection IED including transformer differential

protection (B05)

In many generating plants, the protection system can be designed with a

combination of the two packages, that is, two IEDs of either same type or different

types, will give redundant protection for a generating unit (generator and unit

transformer) depending on the requirements for the plant design.

The packages are configured and ready for use. Analogue inputs and binary input/output circuits are pre-defined.

The pre-configured IED can be changed and adapted with the graphical

configuration tool.

1) The generator should have reverse power protection. If the generator consumes low reverse power at motor operation (< 1 % of SN),

low forward power protection should be used. In other cases, reverse power protection should be used.2) Voltage-restrained time overcurrent protection add (VR2PVOC) can be used instead of the underimpedance protection.
