INTRODUCTION

This document specifies the Protocol Implementation eXtra Information for Testing (PIXIT) of the IEC61850 interface in the MiCOM P445 with firmware version K3 of protection IEDs. Together with the PICS and MICS specifications the PIXIT forms the basis for conformance test according to IEC 61850-10. The PIXIT entries contain information which is not available in the PICS, MICS, TICS document or SCL file.

DOCUMENT STRUCTURE

Each table specifies the PIXIT for applicable ACSI service model as structured in IEC 61850-10. The “Ed” column indicates if the entry is applicable for IEC 61850 Edition 1 and/or Edition 2. A hyphen (“-“) in the Ed column indicates the PIXIT entry is not applicable for any version.

ID	Ed	Description	Value / Clarification
Sr_ex1	2	Measurement deadbands	Each measurement provides a range

configuration in the data model where a minimum and maximum value can be set.

Then deadbands can be specified as a percentage change based on such a range

For this reason, deadband also can be configured based on an absolute value change with the following ranges:

1. deadband = 0, means deadband disabled and measurements follow the instantaneous measurement value.

2. deadband = 1-100,000, means absolute value changes of

0.001 to 100 respectively based on the formula: (deadband/100000)*(max – min).Deadband measurement will be updated when the instantaneous (absolute) value changes by more than the absolute deadband value.

For complex measurement types supporting both magnitude and angle, the deadband will only apply to the magnitude element.

Ct16| 1| Does the IED accept a select/operate on the same control object from 2 different clients at the same time?| Regardless of how or when a control select/operation is received by a MiCOM Px40 IED the same checks are always performed. The return condition for the request will depend upon many factors including:

Is the control available or is it still operating from a previous request

Is the received control value the same as the control status value

In most instances, assuming the two received control request have the same control value, the second select request will result with an “Object- already- selected” response- in SBO control mode, and operate request will result with a “locked-by- other-client” Response-.

LeapSecondsKnown (mandatory) N ClockFailure

Y ClockNotSynchronized

Tm2| 2| Describe the behaviour when all time server(s) ceases to respond

What is the time server lost detection time

| On one time server:

If one time server ceases to respond, the IED automatically switch to synchronize with other active time server.

On all time servers:

If all the time servers cease to respond, the IED keeps the previous synchronization time. The quality bit “ClockNotSynchronized” will be set after a configured time period

System/LLN0$ST$SyncSt provide an indication of the clock synchronization state in IED.

TRUE: Clock is synchronized (Either by SNTP or IRIG-B)

FALSE: Clock is not synchronized

Configurable Default: 90 seconds

Tm3| 2| How long does it take to take over the new time from time server| SNTP 90s (configurable) IRIG-B 10s
Tm4| 2| When is the time quality bit “ClockFailure” set| Not applicable for this IED
Tm5| 1| When the time quality bit “Clock not synchronised” set?| The ‘Clock not synchronized’ bit at power-up has a default status of not synchronized (set to one (1)). When the clock becomes synchronized, the bit will be reset to zero (0).

All available time synchronization sources will affect the ‘Clock not synchronized’ bit. These time sources include SNTP and where applicable, IRIG-B.

When “Poll Rate” expires (It is configurable, default value is 90s), if the connection to time server is still lost, the time quality bit “Clock not synchronised” shall be set.

Ft2| 2| Directory names are separated from the file name by| “/”
Ft3| 1| The maximum file name size including path (recommended 64 chars)| Disturbance record filenames are a based around the following fixed format giving a maximum filename length of twenty eight (28) characters: yyyymmdd_HHMMSS_xxx_rNNN.*

Where:

yyyy = The year, i.e. 2006

mm = The month, i.e. 03 (for March) dd = The day of month, i.e. 15th HH = Hours in 24hr format, i.e. 12 MM = Minutes, i.e. 59

SS = Seconds, i.e. 59

xxx = Milli-seconds, i.e. 999 r = A literal ‘r’ character

NNN = Disturbance record number, i.e. 001

* = The file type, either cfg or dat

Taking into account the directory structure presented in section Ft1, this gives a maximum, fully qualified, filename length of forty four (44) characters.
