IEC 61850 is a powerful standard – also for describing the exchange of Power Quality Information.
IEC 61850 has been extended to support many advanced power quality applications like those defined in IEC 61000-4-30 and EN 50160. IEC 61850-7-4 Edition 2 defines logical nodes, that support modeling and configuring event sequencing with additional quality reporting and waveform recording.
Excerpt of logical nodes for power quality:
- Harmonics (MHAI)
- Flicker (MFLK)
- Imbalanced power calculations (MADV)
- Frequency variation (QFVR)
- Current transient (QITR)
- Current unbalance variation (QUIB)
- Voltage transient (QVTR)
- Voltage unbalance variation (QVUB) and
- Voltage variation (QVVR).
