About The Technical Reference Manual - ABB Relion 670 Series Technical Reference Manual

Section 1
Introduction
1.1.2
36
The Technical Reference Manual (TRM) contains application and functionality
descriptions and it lists function blocks, logic diagrams, input and output signals,
setting parameters and technical data sorted per function. The technical reference
manual should be used as a technical reference during the engineering phase,
installation and commissioning phase, and during normal service.
The Installation and Commissioning Manual (ICM) contains instructions on how to
install and commission the protection IED. The manual can also be used as a reference
during periodic testing. The manual covers procedures for mechanical and electrical
installation, energizing and checking of external circuitry, setting and configuration as
well as verifying settings and performing directional tests. The chapters are organized
in the chronological order (indicated by chapter/section numbers) in which the
protection IED should be installed and commissioned.
The Operator's Manual (OM) contains instructions on how to operate the protection
IED during normal service once it has been commissioned. The operator's manual can
be used to find out how to handle disturbances or how to view calculated and measured
network data in order to determine the cause of a fault.
The Engineering Manual (EM) 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 61850 and DNP3.

About the technical reference manual

The following chapters are included in the technical reference manual.
• Local HMI describes the control panel on the IED and explains display
characteristics, control keys and various local HMI features.
• Basic IED functions presents functions for all protection types that are included in
all IEDs, for example, time synchronization, self supervision with event list, test
mode and other general functions.
• Differential protection describes differential functions and restricted ground fault
protection.
• Impedance protection describes functions for distance zones with their
quadrilateral characteristics, phase selection with load encroachment, power swing
detection and similar.
• Current protection describes functions, for example, over current protection,
breaker failure protection and pole discordance.
• Voltage protection describes functions for under voltage and over voltage
protection and residual over voltage protection.
• Frequency protection describes functions for over frequency, under frequency and
rate of change of frequency protection.
