This document summarizes NetCeler, a French company that has provided automated disturbance analysis software called IVPower to utilities for 20 years. IVPower is a modular system that can be customized with different modules. It has been implemented by various transmission and distribution system operators around the world. IVPower provides automated fault location, asset monitoring, power quality monitoring, and wide area monitoring capabilities. It integrates data from existing utility systems. IVPower supports real-time network supervision to quickly identify faults and post-mortem analysis to improve system efficiency. It automatically analyzes events, locates faults accurately, monitors protection performance, and makes recommendations to utilities.

 Characterization on the
Disturbance
 Perform verifications
systematically
 Support conditional maintenance
 Monitor breakers and relay performance
 Pinpoint abnormal events : e.g late tripping
 Record correct operation to postpone
maintenance, if unnecessary

12. Power Grid Monitoring
12
 1. Real Time Supervision
• Goal: quickly & reliably identify faulty scenario
 Deploy Emergency crew in a targeted small area
 Reduce outage time
 2. Post-mortem Analysis
• Goal: improve efficiency and system quality
 Fault analysis & characterization – type, duration, fault impedance, distance
 Voltage Quality and Stability – power quality
 Asset mulfunctioning with root cause analysis
 Data archival for statistical analysis
 Frequency Stability - Wide Area Monitoring

13. Automated Fault Analysis
13
 Use of oscillographic records (COMTRADE format)
 Time saving: automatic collection and classification
of various event-related following any disturbance.
 Fast indication (within a few minutes) of healthy /
faulty lines
 Fast indication of accurate and reliable fault location
to optimize crew interventions:
 Presentation of the sequence of events,
measurements and key performance indicators to
facilitate and speed up the post mortem analysis
 Providing of fault statistics regarding lines,
transformers, breakers and protection devices.
Main Benefits
Boasts productivity of both dispatching crews and post-mortem analysts

14. Automated Fault Analysis
14
 Fault position in km from substation
 Fault accuracy: 5% of line length, (98%
prob.)
 Geographical view with the fault position
 Graphical representation of the fault
 Red rectangle : tolerance zone
Geo-located indication of the fault position

15. Automated Fault Analysis

 L1-G short circuit on line Klm-WOL 536
 The short circuit is located at 4.77 km [Mast356;Mast355] +/- 1.27 km from station Wolmirstedt
 Line Klm-Wol 536 is surely faulty
 L1-G short circuit on line Eu-Wd 208
 The short circuit is located at 62.35 km [Mast181;Mast182] +/- 3.36 km from station Eula
 Line EU-WD is surely faulty

elements, IVPower suggests
to reclose the line manually
According to the analyzed
elements, IVPower suggests NOT
to reclose the line manually

16. Automated Fault Analysis
16
 Presented in a relative time scale
 The time origin : start of fault
 Located faults and relay trips shown
by default
 Additionally, feeder, station binary
signals or additional (secondary) fault
locations may be added to the event
timeline
Sequence of fault event

17. Protection Performance Monitoring
17
 Detection of latent defects in the protection system
 Every disturbance event will trigger an automated performance analysis of the
concerned IED
 Maintenance inspections planned according to IED performances, not time
Main Benefits

18. Protection Performance Monitoring
18
 Selection of the device type:
relays, CB’s
 Upon every disturbance event is
an automated performance test
for concerned IED’s and CB’s
 Statistical data can be linked to
external data historian systems
 Custom protection monitoring
rules can be added through a
development environment
