Introduction

1 Introduction to the operators manual

1.1 About the complete set of manuals for an IEDThe users manual (UM) is a complete set of five different manuals:

The Application Manual (AM) contains application descriptions, setting guidelines and settingparameters sorted per function. The application manual should be used to find out when and forwhat purpose a typical protection function could be used. The manual should also be used whencalculating settings.

The Technical Reference Manual (TRM) contains application and functionality descriptionsand it lists function blocks, logic diagrams, input and output signals, setting parameters and tech-nical data sorted per function. The technical reference manual should be used as a technical ref-erence during the engineering phase, installation and commissioning phase, and during normalservice.

The Installation and Commissioning Manual (ICM) contains instructions on how to installand commission the protection IED. The manual can also be used as a reference during periodictesting. The manual covers procedures for mechanical and electrical installation, energizing andchecking of external circuitry, setting and configuration as well as verifying settings and per-forming directional tests. The chapters are organized in the chronological order (indicated bychapter/section numbers) in which the protection IED should be installed and commissioned.

The Operators Manual (OM) contains instructions on how to operate the protection IED dur-ing normal service once it has been commissioned. The operators manual can be used to findout how to handle disturbances or how to view calculated and measured network data in orderto determine the cause of a fault.

The IED 670 Engineering guide (EG) contains instructions on how to engineer the IED 670products. The manual guides to use the different tool components for IED 670 engineering. Italso guides how to handle the tool component available to read disturbance files from the IEDson the basis of the IEC 61850 definitions. The third part is an introduction about the diagnostictool components available for IED 670 products and the PCM 600 tool.

The IEC 61850 Station Engineering guide contains descriptions of IEC 61850 station engi-neering and process signal routing. The manual presents the PCM 600 and CCT tool used forstation engineering. It describes the IEC 61850 attribute editor and how to set up projects andcommunication.

Introduction

1.2 About the operators manual

Use the operators manual for instruction on how to perform common tasks during normal ser-vice.

The operators manual contains the following chapters:

The chapter Safety information presents warnings and notices, which the usershould pay attention to.

The chapter Overview describes operations an operator may perform on a dailybasis or when the need arises.

The chapter Understand the local human-machine interface describes how touse the human-machine interface.

The chapter Understand the HMI tree describes the different menu trees.

The chapter Read measured values describes how to locate and identify avail-able measurement data.

The chapter Event list describes the location and nature of recorded events. The chapter Handle disturbances describes how to retrieve disturbance infor-

mation and reset alarms.

The chapter Read and change settings describes how to locate, and change set-tings and parameters.

The chapter Diagnose IED status describes the location and use of availablediagnostic tools.

The chapter Test the IED describes the tests applicable to the IED.

The chapter Control and supervise the bay describes how to use the SingleLine Diagram to open and close primary apparatuses.

The chapter Reset describes resetting procedures.

The chapter Authorizationdescribes user categories and password procedures.

The chapter Glossary describes words and acronyms used in the literature de-scribing the IED.

This manual does not contain any instructions for commissioning or testing.

1.3 Intended audience

1.3.1 General

The operators manual addresses the operator, who operates the IED on a daily basis.

1.3.2 Requirement

The operator must be trained in and have a basic knowledge of how to operate protection equip-ment. The manual contains terms and expressions commonly used to describe this kind of equip-ment.

Operator overview Chapter 3

Overview

1 Operator overview

The Human machine interface (HMI) on the IED provides an ideal mechanism for the day to dayoperation and even advanced use of the IED. The keypad, LCD and LEDs on the front of theIED are what constitute the HMI. Troubleshooting, apparatus control, monitoring, setting andconfiguring are all possible via this interface. Through the screens and menu elements available,as well as the keypad, the user is able to navigate throughout the menu structure and move fromscreen to screen. This document is, to a great extent, arranged in the same way as the IED soft-ware is structured and describes all aspects of operation via the HMI.

The operator can document disturbances so that their causes can be analyzed and evaluated forfuture reference. For example, the fault currents and voltages at the time of the fault can be doc-umented. The operator can also retrieve data about protected objects, providing further informa-tion for fault analysis. This implies viewing the mean value of current, voltage, power andfrequency or primary and secondary measured phasors. The operator can check the IED statusat any time.

In some cases the operator may need to change the way the IED operates. This might includechanging the active setting group or a parameter value. This must always be done strictly accord-ing to applicable regulations because un-authorized changes may lead to severe damage of the

protected object especially if a fault is not properly disconnected.

LED Chapter 4



5 LED

The LED module is a unidirectional means of communicating. This means that events may occurthat activate a LED in order to draw the operators attention to something that has occurred andneeds some sort of action.

5.1 Status indication LEDs

There are three LEDs above the LCD. The information they communicate is described in thetable below.

5.2 Indication LEDs

The LED indication module comprising 15 LEDs is standard in IED 670s. Its main purpose isto present an immediate visual information for protection indications or alarm signals.

There are alarm indication LEDs and hardware associated LEDs on the right hand side of thefront panel. The alarm LEDs are found to the right of the LCD screen. They can show steady orflashing light. Flashing would normally indicate an alarm. The alarm LEDs are configurable us-ing the PCM 600 tool. This is because they are dependent on the binary input logic and can there-fore not be configured locally on the HMI. Some typical alarm examples follow:

Bay controller failure

CB close blocked

Interlocking bypassed

Differential protection trip

SF6 Gas refill

Position error

CB spring charge alarm

Oil temperature alarm

Thermal overload trip

Bucholtz trip

LHMI setup and test screen Chapter 4



6 LHMI setup and test screen

The contrast setting of the LCD can be adjusted from the LHMI menu tree when the IED hasstarted or from the PST tool in PCM 600. The contrast setting adjusted with one of these meth-ods is an offset to a factory set basic contrast setting.

Normally the basic contrast setting is not changed, but can if needed be adjusted as follows:

Activate the setup and test screen for the LHMI by keeping the Reset key pressed immediatelyafter the dc power to the IED has been applied.

By pressing keys according to information on the setup and test screen

the basic contrast level of the LCD screen can be changed

the LCD screen can be toggled to inverse mode

the indication LEDs can be tested

Press the I key to save and exit the screen and wait for the IED to start. Observe that only thebasic contrast setting will be saved.

Note!

The screen shows I which here means the Close key.

Overview Chapter 6


1 Overview

The measurement menu contains primarily analog measurement data. External signals can alsobe viewed as they are or as they appear in the Signal Matrix Tool (SMT). These signals are avirtual representation of the hard wired signals on the various inputs and outputs. The SMT isonly accessible via the PCM and is intended to simplify the configuration of the IED. It allowshardware changes to be made without having to reconfigure the internal logic. Signals that can

be used in the SMT are indicated with the Suffix SMT.

The functions available under measurements are outlined below.

1. Analog primary values are the quantities measured on the primary side of the cur-rent and voltage transformers (CTs and VTs).

2. Analog secondary values are the quantities measured on the secondary side of thecurrent and voltage transformers. These are the quantities measured on the Trans-former module (TRM) inputs.

3. Analog mean values are the quantities measured at the inputs of the milliamperemodule (MIM).

4. Under Monitoring a number of submenus are available. These include Servicevalues, Current phasors, Voltage phasors, Current sequence components andVoltage sequence components.

5. Metering displays the pulse counter function. The measurements available hereshow pulse counter status data.

All measurement descriptions in this document reflect the maximum number of hardware unitspossible in any application. In reality the hardware in the IED will be chosen according to a par-ticular application. For example, it is possible to equip a 1/1 x 19 case IED with 14 I/O modules.In reality fewer I/O modules may be installed. In the measurements menu the operator will onlysee data from the hardware and software installed.

justed to suit the application. This means that an input 3 mA may be displayed as temperatureof 45 degrees. The output values shown are without units.

4.1.2 Signal matrix for mA inputs (SMMI)

Measurements\Analog Mean Values\SMT mA modules\Instance

Displays the input signals coming into the Milli-ampere Module. Each module has six physicalinputs with an input tolerance of +/- 20mA. The value displayed depends on the settings appliedto this board which may for example cause an input of 3mA to show a value 30. The SMT mAmodules are the virtual representation of MIMs in the Signal Matrix Tool.

2.3 Analog modules

2.3.1 Overview

Under Analog modules in the General settings menu there are settings for Analog inputs and I/Omodules. Within each instance of analog input there are settings for all 12 channels that includethe name of the channel, star point of the CT circuit, the primary and secondary values from the

measuring transformers (CTs and VTs). The channel type and ratings are shown but cannot bechanged.

The settings for binary inputs and outputs even include the milliampere input modules. A mixof up to 14 instances of BIM, BOM and IOM is possible depending on the physical configurationof the IED. Operation ON or OFF can be set for all of these and for the BIMs oscillation releaseand oscillation block settings are available. These settings are on board level and apply to all bi-nary inputs or outputs on a board.
