In vertical communications, the protection IED can generate events that are automatically reported to any listening clients. These communications are configured via a series of predefined data sets and corresponding report control blocks. The data sets are used to configure what data is sent and the report control block is used to configure when data is sent.
The IED connectivity package includes predefined data sets and control blocks for vertical MMS event reporting. These data sets are used in predefined reporting control blocks for five clients. The selected data in the data sets is suitable to most of the different applications and the selected default data automatically considers the used protection IED type and options.
The data sets and report control blocks can be modified using the IEC 61850 Configuration tool or any IEC 61850 system configuration tool, however, this should only be done by individuals that are extremely familiar with both the protection IEDs and IEC 61850. Inappropriate modifications can result in misoperation of the protection IED.
- StatIed – generic status information of IEDs
- StatIo – inputs, outputs, LEDs
- StatUrg – measurement limit supervision, control feedback
- StatNrml – protection start and trip signals, autoreclosing status
- StatDR – digital fault recorder status
- MeasReg – registered measurement values at faults
- MeasFlt – measurements
When function blocks are added to or removed from a IED configuration also the default data sets and the content of data sets are automatically modified to follow the IED data model. If all data does not fit into one data set, two data sets with suffixes "A" and "B" are created.
The protection IEDs support both buffered and unbuffered event reporting. In the predefined configuration all report control blocks are configured to use buffered reporting. The benefit of buffered reporting is that it buffers events during communication breaks and thus no events are lost. Further, a single data set can only be used by one report control block and the same data set entry cannot be used in different event reporting data sets.
The default values for the data sets and control blocks are suitable for most applications. The protection IED allows free renaming and editing of report control blocks and data sets. Only users who have an in-depth understanding of the protection IED and IEC 61850 should modify the default configuration. Description of data in default data sets is available in the parameter list.
