8.6.1 Introduction
The configuration for Disturbance Recording can currently only be used by MicroSCADA via ‘.sasmsc’ file. If you need any other program to upload Disturbance Recording files from an IED for further processing, a configuration in IET600 will currently not be helpful.
In the following description, the following terms will be used:
Disturbance Recording Collector for an IED that uploads Disturbance Recording files from individual Disturbance Recording Servers and collects them in a defined place in the file system.
8.6.2 Configuration
The configuration for Disturbance Recording is done in the ‘IED Settings’ Editor Disturbance Recording can only be configured for:
IEDs classified as “Protection IEDs” (see chapter 8.2.7, “Configure IEDs” for more details), these IEDs act as Disturbance Recording Servers.
OPC Servers, these IEDs act as Disturbance Recording Collectors.
If all values are greyed out, preventing you from configuring individual settings, please check whether one of the above conditions is fulfilled.
Column Function
Disturbance Recording Enabled
Checking this flag on a Disturbance Recording Server (a Protection IED) will indicate to a client that it should try to upload Disturbance Records from this IED. The flag is en-abled only
Checking this flag on a Disturbance Recording Collector (OPC Server) will indicate that it is an active client.
Disturbance Recording Delete Recording After Upload
Checking this flag will cause a Disturbance Recording Collector to try and remove Disturbance Records from an IED after a successful upload.
When having several Disturbance Recording Collectors doing uploads from an IED, it is important to set this flag correctly (normally only one Collector should have this flag set).
Disturbance Recording Use IEC 61850 Default Directory
IEC 61850 specifies a fixed directory on a protection IED, from where Disturbance Records can be retrieved by a Disturbance Recording Collector: the IED must have a Logical Device containing an LN of class RDRE; the path is then [LDName]\COMTRADE.
Checking this flag on a Disturbance Recording Server will cause the Disturbance Recording Directory to be set to this fixed value.
Column Function Disturbance Recording
Directory
The directory where the Disturbance Recording files are stored.
On a Disturbance Recording Server, it is the directory from where the Disturbance Recording Collector will try to upload files. This value is read-only, if the ‘Disturbance Recording Use IEC 61850 Default Directory’ flag is checked. See chapter 8.6.3 below for detailed recommen-dations how to set this path.
On a Disturbance Recording Collector (currently only sup-ported for ABB OPC Servers), it is the root directory where uploaded Disturbance Record files will be saved, (the substructure may vary between different Disturbance Recording Collectors).
Disturbance Recording Polling Period
On a Disturbance Recording Server, the minimum sensi-ble polling period. Used for Legacy purposes; mostly an event-triggered upload is used.
On a Disturbance Recording Collector, the actual polling period, should not be smaller than the largest minimum polling period of any Disturbance Recording Server.
Used for legacy purposes; today, mostly an event-trig-gered upload is used.
Disturbance Recording MMS Upload Capability
A flag indicating whether Disturbance Records can be up-loaded via 8-MMS protocol (IEC 61850).
For IEC 61850 Ed.2 IEDs, this is read-only, as it is de-fined in the Services of the IED.
For IEC 61850 Ed.1 IEDs, the default value is taken from the IED Capabilities. If several Capabilities are selected, 8-MMS will be preferred over FTP over FTPS.
Disturbance Recording FTP Upload Capability
A flag indicating whether Disturbance Records can be up-loaded via FTP protocol (IEC 61850).
For IEC 61850 Ed.2 IEDs, this is read-only, as it is de-fined in the Services of the IED.
For IEC 61850 Ed.1 IEDs, the default value is taken from the IED Capabilities. If several Capabilities are selected, 8-MMS will be preferred over FTP over FTPS.
Disturbance Recording FTPS Upload Capability
A flag indicating whether Disturbance Records can be up-loaded via FTPS protocol (IEC 61850).
For IEC 61850 Ed.2 IEDs, this is read-only, as it is de-fined in the Services of the IED.
For IEC 61850 Ed.1 IEDs, the default value is taken from
8.6.3 Disturbance Recording Directory Recommendations
Be aware that the handling of the Disturbance Recording Directory on a Disturbance Recording Server is currently not yet consistent. As a guidance we suggest to use the following paths (without the “”):
For IED611 series, use “COMTRADE\” as path (an empty path will upload unex-pected files).
For IED615 series, use “COMTRADE\” as path (an empty path will upload unex-pected files).
For IED620 series, use “COMTRADE\” as path (an empty path will upload unex-pected files).
For most other ABB IEDs, use “*” (the IED will automatically use its internally known path).
For many 3rdparty IEDs, try “*” (the IED will automatically use its internally known path). If this does not work, consult the manual.
For Ed.2-compliant IEDs, you may try “Use IEC 61850 Default Directory”; however, the current experience is that this fails fairly often; also this is not useful when using protocols other than 8-MMS for upload. Always test this setting, and use “*”, if it does not work.
8.6.4 Export
The engineer does not need to export this information separately, as it will automatically be included in an ‘.sasmsc’ file, provided that the following conditions are met:
at least one OPC Server belonging to the MicroSCADA must be configured as a Disturbance Recording Collector by setting its ‘Disturbance Recording Enabled’ flag to true.
