C.2.6 Mmxu: Analog Measured Values - GE C70 Instruction Manual

APPENDIX C
A limited number of measured analog values are available through the MMXU logical nodes.
Each MMXU logical node provides data from a C70 current and voltage source. There is one MMXU available for each
configurable source (programmed in the
from C70 source 1, and MMXU2 provides data from C70 source 2.
MMXU data is provided in two forms: instantaneous and deadband. The instantaneous values are updated every time a
read operation is performed by a client. The deadband values are calculated as described in IEC 61850 parts 7-1 and 7-3.
The selection of appropriate deadband settings for the C70 is described in chapter 5 of this manual.
IEC 61850 buffered and unbuffered reporting capability is available in all MMXU logical nodes. MMXUx logical nodes pro-
vide the following data for each source:
• MMXU1.MX.TotW: three-phase real power
• MMXU1.MX.TotVAr: three-phase reactive power
• MMXU1.MX.TotVA: three-phase apparent power
• MMXU1.MX.TotPF: three-phase power factor
• MMXU1.MX.Hz: frequency
• MMXU1.MX.PPV.phsAB: phase AB voltage magnitude and angle
• MMXU1.MX.PPV.phsBC: phase BC voltage magnitude and angle
• MMXU1.MX.PPV.phsCA: Phase CA voltage magnitude and angle
• MMXU1.MX.PhV.phsA: phase AG voltage magnitude and angle
• MMXU1.MX.PhV.phsB: phase BG voltage magnitude and angle
• MMXU1.MX.PhV.phsC: phase CG voltage magnitude and angle
• MMXU1.MX.A.phsA: phase A current magnitude and angle
• MMXU1.MX.A.phsB: phase B current magnitude and angle
• MMXU1.MX.A.phsC: phase C current magnitude and angle
• MMXU1.MX.A.neut: ground current magnitude and angle
• MMXU1.MX.W.phsA: phase A real power
• MMXU1.MX.W.phsB: phase B real power
• MMXU1.MX.W.phsC: phase C real power
• MMXU1.MX.VAr.phsA: phase A reactive power
• MMXU1.MX.VAr.phsB: phase B reactive power
• MMXU1.MX.VAr.phsC: phase C reactive power
• MMXU1.MX.VA.phsA: phase A apparent power
• MMXU1.MX.VA.phsB: phase B apparent power
• MMXU1.MX.VA.phsC: phase C apparent power
• MMXU1.MX.PF.phsA: phase A power factor
• MMXU1.MX.PF.phsB: phase B power factor
• MMXU1.MX.PF.phsC: phase C power factor
The following list describes the protection elements for all UR-series relays. The C70 relay will contain a subset of protec-
tion elements from this list.
