IEC 61850 MSTA Module
Module icon
Overview
It maps the appropriate ION values to their IEC 61850 counterparts. The MSTA Logical Node provides metering statistics, such as average, minimum and maximum values. Only one instance of this module can exist. Because this module is specific to supporting the IEC 61580 protocol, it can be deleted if IEC 61850 is not required.
For more information about IEC 61850, please refer to the IEC 61850 and ION Technology protocol document.
Inputs
By default, the MSTA module inputs are linked to the outputs of the related Maximum, Minimum and Sliding Window Demand modules.
This register is linked to the output register of the kVA tot mean Sliding Window Demand module, which provides the average apparent power value. Units are kVA.
This register is linked to the output of the kVA tot mx Maximum module, which provides the maximum apparent power value. Units are kVA.
This register is linked to the output of the kVA tot mn Minimum module, which provides the minimum apparent power value. Units are kVA.
This register is linked to the output register of the kW tot mean Sliding Window Demand module, which provides the average real power value. Units are kW.
This register is linked to the output of the kW tot mx Maximum module, which provides the maximum real power value. Units are kW.
This register is linked to the output of the kW tot mn Minimum module, which provides the minimum real power value. Units are kW.
This register is linked to the output register of the kVAR tot mean Sliding Window Demand module, which provides the average reactive power value. Units are kVAR.
This register is linked to the output of the kVAR tot mx Maximum module, which provides the maximum reactive power value. Units are kVAR.
This register is linked to the output of the kVAR tot mn Minimum module, which provides the minimum reactive power value. Units are kVAR.
Setup registers
The MSTA module has no setup registers.
Output registers
These registers are formatted and named according to IEC 61850 protocol standards. These registers have the same units as their corresponding inputs.
These registers contain the instantaneous and deadbanded values for the average apparent power, derived from the AvVA input.
These registers contain the instantaneous and deadbanded values for the maximum apparent power, derived from the MaxVA input.
These registers contain the instantaneous and deadbanded values for the minimum apparent power, derived from the MinVA input.
These registers contain the instantaneous and deadbanded values for the average real power, derived from the AvW input.
These registers contain the instantaneous and deadbanded values for the maximum real power, derived from the MaxW input.
These registers contain the instantaneous and deadbanded values for the minimum real power, derived from the MinW input.
These registers contain the instantaneous and deadbanded values for the average reactive power, derived from the AvVAr input.
These registers contain the instantaneous and deadbanded values for the maximum reactive power, derived from the MaxVAr input.
These registers contain the instantaneous and deadbanded values for the minimum reactive power, derived from the MinVAr input.
Events produced by the module are recorded in the Event register. Possible events and their associated priority numbers are shown in the following table.
Event priority group | Priority | Description |
---|---|---|
Reset | 5 | A module reset has occurred. |
Setup Change | 10 | Input links, setup registers or labels have changed. |
Information | 25 | not available input caused output to go not available. |
The Event output register stores the following information for each ION event: time stamp, priority, cause, effect, and any values or conditions associated with the cause and effect.
