Testing disturbance report

9.1.1

Introduction

The following sub-functions are included in the disturbance report function:

•

Disturbance recorder

•

Event list

•

Event recorder

If the disturbance report is set on, then its sub-functions are also set up and so it is not possible to

only switch these sub-functions off. The disturbance report function is switched off (parameter

Operation = Off) in PCM600.

9.1.2

Disturbance report settings

When the IED is in test mode, the disturbance report can be made active or inactive. If the

disturbance recorder is turned on during test mode, recordings will be made. When test mode is

switched off all recordings made during the test session are cleared.

To locate disturbance recorder in PCM600,

Open the Disturbance Handling tool for the IED in the plant structure in PCM600

Right-click and select Read Recordings Information.

9.1.3

Disturbance recorder (DR)

A Manual Trig can be started at any time. This results in a recording of the actual values from all

recorded channels.

The Manual Trig can be started as follows:

Open the Disturbance handling tool for the IED in the plant structure in PCM600.

Right-click and select Execute manual Trig in the window Available recordings in IED.

Read the required recordings from the IED.

Refresh the window Recordings and select a recording.

Right-click and select Create Report or Open With to export the recordings to any disturbance

analyzing tool that can handle COMTRADE formatted files.

Evaluation of the results from the disturbance recording function requires access to a PC either

permanently connected to the IED or temporarily connected to the LHMI service kit. The PCM600

software package must be installed in the PC.

Disturbance upload can be performed by the use of PCM600 or by any third party tool with IEC

61850 protocol. Reports can automatically be generated from PCM600. Disturbance files can be

analyzed by any tool reading COMTRADE formatted disturbance files.

It could be useful to have a printer for hard copies. The correct start criteria and behavior of the

disturbance recording function can be checked when IED protective functions are tested.

When the IED is brought into normal service it is recommended to delete all recordings, made during

commissioning to avoid confusion in future fault analysis.
