IEC 61850 MSQI Module

The IEC 61850 MSQI module represents the Sequences and Imbalances (MSQI) Logical Node in IEC 61850 protocol.

Overview

It maps the appropriate ION values to their IEC 61850 counterparts. The MSQI Logical Node is used to represent the sequences in a three/multi-phase power system. Sequence calculations are made available on the meter through the Symmetrical Components ION modules. 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.

NOTE: This module is configured as part of the meter’s implementation of the IEC 61850 protocol. Manual creation and configuration of this module, or modification of an existing module, is an advance feature that should only be undertaken by personnel with a thorough understanding of ION and IEC 61850 protocols, and the system in which the meter is installed.

NOTE: The registers and settings available in this module depend on the device or node you are configuring, as well as its firmware and template versions. Not all registers or settings are available on all devices or the Virtual Processor, and labels may vary.

Inputs

By default, the MSQI module inputs are linked to the outputs of the current and voltage Symmetrical Components modules.

NOTE: If input registers are changed, the new inputs must have the same units of measure as the original input.

I PosSeqMag, I PosSeqPhs

These registers are linked to the PosSeqMag and the PosSeqPhs output registers of the current Symmetrical Components module, which provide the magnitude of positive sequence current and the phase angle of positive sequence current, respectively. Units are Amps.

I NegSeqMag, I NegSeqPhs

These registers are linked to the NegSeqMag and the NegSeqPhs output registers of the current Symmetrical Components module, which provide the magnitude of negative sequence current and the phase angle of negative sequence current, respectively. Units are Amps.

I ZeroSeqMag, I ZeroSeqPhs

These registers are linked to the ZeroSeqMag and the ZeroSeqPhs output registers of the current Symmetrical Components module, which provide the magnitude of zero sequence current and the phase angle of zero sequence current, respectively. Units are Amps.

V PosSeqMag, V PosSeqPhs

These registers are linked to the PosSeqMag and the PosSeqPhs output registers of the voltage Symmetrical Components module, which provide the magnitude of positive sequence voltage and the phase angle of positive sequence voltage, respectively. Units are Volts.

Setup registers

The MSQI 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.

Event

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.
