MiCOM M830

Disturbance Recorder


2/122

Application and Scope

The MiCOM M830 device is a cost

effective disturbance recorder in

compact design. The M830

provides disturbance data recordingin medium- and high-voltage

systems. The systems can be solidly-

grounded, resistance grounded,

Petersen coil or insulated neutral

type.

The device has the following main

functions:

Definite-time overcurrent trigger,4 stages

Inverse-time overcurrent trigger,1 stage

Over-/undervoltage trigger

Limit value monitoring

Programmable scheme logic.

All main functions are individually

configurable and can be disabled

or enabled by the user as desired.

By means of a straight-forward

configuration procedure, the user

can adapt the device flexibly to the

scope required in each particular

application. Due to the powerful,

freely configurable logic of the

device, special applications can be

accommodated.

In addition to the features listed

above, as well as comprehensive

self-monitoring, the following

global functions are available in

the devices:

Parameter subset selection(4 alternative setting groups)

Operating data recording(time-tagged signal logging)

Disturbance recording(time-tagged signal recording

together with disturbance

recording of all measured

signals: phase currents, phase-to-

ground voltages and derived

residual current and neutral

displacement voltage.

The M830 is of compact design.

The boards are housed in a robust

aluminum case and electrically

connected via ribbon cables.

The nominal currents or the

nominal voltages, respectively, of

the measuring inputs can be set

with the help of function

parameters.

The nominal voltage range of the

optical coupler inputs is 24 to

250 V DC without internal

switching.

The auxiliary voltage input forthe power supply is a wide-range

design which can be internally

switched from a nominal voltage

range of 110 to 250 V DC (or 100

to 230 V AC) to 24 to 60 V DC. All

output relays are suitable for both

signal and trip duties.

Control and Display

Local control panel

17 LED indicators, 12 of whichallow freely configurable function

assignment

PC interface

Communication interfaces(optional)

IRIG-B time synchronization(optional).

Information exchange is via the

local control panel, the PC interface

and the optional communication

interfaces. Using this information

interface, the devices can be

integrated with substation control

systems or telecontrol systems. The

communication interface conformsalternatively to IEC 60870-5-103,

IEC 60870-5-101, DNP 3.0 or

Modbus.

Main Functions

Main functions are autonomous

function groups and can be

individually configured or disabled

to suit a particular application.

Function groups that are not

required and have been disabled by

the user are masked completely

(except for the configuration

parameter) and functional support

is withdrawn from such groups.

This concept permits an extensive

scope of functions and universal

application of the device in a single

design version, while at the same

time providing for a clear and

straight-forward setting procedure

and adaptation under

consideration.

Definite-Time Overcurrent

Trigger

A four-stage definite-time

overcurrent trigger (TRIG1) function

can be activated to start disturbance

recording.

Three separate measuring elements

are available for this purpose:

Maximum phase current

Negative-sequence current

Residual current

Inverse-Time Overcurrent

Trigger

The single-stage inverse-time

overcurrent trigger (TRIG2) function

operates with three separate

measuring elements:

Maximum phase current

Negative-sequence current Residual current

For the individual measuring

elements, the user can select from a

multitude of tripping characteristics

to trigger disturbance recording (see

table below).

Over-/Undervoltage Protection

The over-/undervoltage-time trigger

evaluates the fundamental of the

phase voltages and of the neutral

displacement voltage as well as the

positive-sequence voltage and

negative-sequence voltage obtained

from the fundamental of the three

phase-to-ground voltages. Two

definite-time-delay overvoltage

stages each are provided for

evaluation of the neutral

displacement voltage and negative-

sequence voltage. Two additional

definite-time-delay undervoltage

stages each are provided for

evaluation of the phase voltages

and the positive-sequence voltage.

Evaluation of the phase voltages

can be performed using either the

phase-to-phase voltages or the

phase-to-ground voltages as

desired. The neutral displacement

voltage is formed internally from the

three phase-to-ground voltages.

Limit Monitoring

A multitude of currents, voltages aremonitored to aid operation of the

power network. This function is not

intended to be used for any

protection purposes, as it has an

inherent 1 second delay.

E.g. for the 3-phase currents, the

Tripping Time Characteristics of Inverse-Time Overcurrent Trigger


4/124

phase-to- ground voltages and the

phase-to- phase voltages the

highest and the lowest value is

determined. These are evaluated

using an operate value and time

delay set by the user. Thereby, these

currents and voltages can be

monitored for exceeding an upper

limit or falling below a lower limit.

Programmable Logic

User-configurable logic enables the

user to set up logic operations on

binary signals within a framework of

Boolean equations. By means of a

straightforward configuration

procedure, any of the signals of the

protection device can be linked by

logic OR or AND operations withthe possibility of additional negation

operations.

The output signal of an equation

can be fed into a further, higher-

order equation as an input signal

thus leading to a set of interlinked

Boolean equations.

The output signal of each equation

is fed to a separate timer stage with

two timer elements each and a

choice of operating modes. Thus

the output signal of each equation

can be assigned a freely

configurable time characteristic.

The two output signals of each

equation can be configured to each

available input signal after logic OR

linking. The user-configurable logic

function is then able to influence the

individual functions without external

wiring (block, reset, trigger, for

example).

Via non-storable continuous signals,

monostable trigger signals and

bistable stored setting/resetting

signals, the Boolean equations can

be controlled externally via any of

the devices interfaces.

Global Functions

Functions operating globally allow

the adaptation of the devicesinterfaces to the protected power

system, offer support during

commissioning and testing and

provide continuously updated

information on the operation, as

well as valuable analysis results

following events in the protected

system.

Clock Synchronization

The devices incorporate an internal

clock with a resolution of 1 ms. Allevents are time-tagged based on

this clock, entered in the recording

memory appropriate to their

significance and signaled via the

communication interface.

Alternatively two external

synchronization signals can be used

according to the selected

communication protocol: using one

of the protocols Modbus, DNP3,

IEC 60870-5-103, IEC 60870-5-101 the device will be synchronized

by a time telegram from a higher-

level substation control system or in

any other case it will be

synchronized using the IRIG-B signal

input. The internal clock will then be

adjusted accordingly and operate

with an accuracy of 10 ms if

synchronized via protocol and

1 ms if synchronized via IRIG-B

signal.

Parameter Subset Selection

The function parameters for setting

the protection functions are, to a

large extent, stored in four

independent parameter subsets.

Switching between these alternative

setting groups is readily achieved

via any of the devices interfaces.

Operating Data Recording

For the continuous recording of

processes in system operation or of

events, a non-volatile ring memory

entries is provided. The relevant

signals, each fully tagged with date

and time at signal start and signal

end, are entered in chronological

sequence. Included are control

actions such as the enabling or

disabling of functions as well as

local control triggering for testingand resetting. The onset and end of

events in the network, as far as

these represent a deviation from

normal operation (overload, ground

fault or short-circuit, for example)

are recorded.

Disturbance Recording

Disturbance recording comprises

event and disturbance recording

along with the stored faultmeasurands.

While a trigger condition persists in

the power system, the relevant

signals, each fully tagged with date

and time at signal start and signal

end, are entered into a non-volatile

memory in chronological sequence .

Furthermore, the sampled values of

all analog input variables such as

phase currents and phase-to-

ground voltages are recordedduring a fault.

Up to eight faults can be recorded.

If more than eight faults occur

without interim memory clearance

then the oldest fault recording is

overwritten.

Self-Monitoring

Comprehensive self-monitoringprocedures within the devicesensure that internal hardware or

software errors are detected and donot cause malfunctions of theprotective devices.

As the auxiliary voltage is turned on,

a functional test is carried out.

Cyclic self-monitoring tests are run

during operation. If test results

deviate from the default value then

the corresponding signal is entered

into the non-volatile monitoring

signal memory. The result of the

fault diagnosis determines whether

a blocking of the protection device

will occur or whether a warning only

is issued.

Control

All data required for operation of

the disturbance recorder are

entered from the integrated local

control panel, and the data

important for system management

are read out there as well. The

following tasks can be handled via

the local control panel:

Readout and modification ofsettings

Readout of cyclically updatedmeasured operating data and

state signals

Readout of operating data logsand of monitoring signal logs

Resetting of the unit andtriggering of further control

functions designed to support

testing and commissioning tasks

The local control panel shown in

Figure 2 comprises the local control

elements and functions described

below.

Display

(1)The integrated local control

panel has a LCD displaywith4x20 alphanumeric characters.

17 LED indicators are provided forsignal display.

(2)5 LED indicators arepermanently assigned to signals.

(3)The remaining 12 LED

indicators are available for free

assignment by the user. Separate

adhesive labels are provided for

user-defined labeling of these

LED indicators according to the

chosen configuration.

Menu Tree

(4)By pressing the

cursor keys and

guided by the LCD display, the

user moves within a plain text

menu. All setting parameters

and measured variables as well

as all local control functions are

arranged in this menu which is

standardized for all devices of

the system. Changes to the

settings can be prepared and

confirmed by means of the

ENTER key which alsoserves to trigger local control

functions. In the event of

erroneous entries, exit from the

EDIT MODE with rejection of the

entries is possible at any time by

means of the CLEARkey C .

When the EDIT MODE is not

activated, pressing the CLEARkey has the effect of resetting the

indications. Pressing the READ

key G provides direct access toa preselected point in the menu.

Function keys

(5)4 function are available for free

assignment to any logical binary

input or control function. This

facilitates control, e.g. of manual

trip and close commands.

Type Label and PC Interface

(6)Type identification label with

information on the order

number, serial number and the

nominal electrical values.

(7)Dust covered (not shown here)

Figure 2: Local control panel

Measured Value Panels

The configuration of the localcontrol panel allows the

installation of measured value

Panels on the LCD display. The

Panels are automatically

displayed for certain operation

conditions of the system. Priority

increases from normal operation

to operation under overload

conditions and finally to

operation following a short-

circuit in the system. Thedisturbance recorder thus

provides the measured value

data relevant for the prevailing

conditions.

Password Protection

Access barriers protect the entermode in order to guard against

inadvertent or unauthorized

changing of parameter settings

or triggering of control functions.
