'''Automated Fault Analysis''' ('''AFA''') is a software-based approach used in the electrical power industry to detect, localize, and diagnose faults in [[Electric power transmission|transmission]] and [[Electric power distribution|distribution]] systems. By analyzing digital disturbance recordings collected from [[Substation|substations]] and field equipment, AFA aims to improve grid reliability, reduce [[power outage]] durations, and support operational decision-making.

Line 7 ⟶ 16:

Automated Fault Analysis systems collect and interpret data from [[Intelligent electronic device|Intelligent Electronic Devices]] (IEDs), such as Digital Fault Recorders (DFRs), [[Protective relay|Protection Relays]], and Power Quality Meters. These systems process standardized event data to reconstruct the sequence of events, identify the nature and ___location of faults, and notify grid operators with actionable insights.

AFA is often integrated into wider energy monitoring environments such as [https://en.wikipedia.org/wiki/SCADA [SCADA]] (Supervisory Control and Data Acquisition), Energy Management Systems (EMS), and Wide-Area Monitoring Systems (WAMS).

== Key Functions ==

Line 25 ⟶ 34:

* A central application server for processing and analysis

* A data collector for receiving standardized disturbance files (e.g., [https://en.wikipedia.org/wiki/[Comtrade |COMTRADE]])

* A database for storing historical fault data and configurations

* A secure user interface (often web-based) for visualization and diagnostics

Supported communication protocols may include:

* [https://en.wikipedia.org/wiki/[International%20Electrotechnical%20Commission Electrotechnical Commission|IEC]] 61850

* IEC 60870-5-104

* [[MODBUS]]

* [[Secure file transfer program|SFTP]] / [[HTTPS]] / [[MQTT]]

* [http://en.wikipedia.org/wiki/Secure%20file%20transfer%20program SFTP] / [https://en.wikipedia.org/wiki/HTTPS HTTPS] / [https://en.wikipedia.org/wiki/MQTT MQTT]

== Standards and Data Formats ==

Line 39 ⟶ 48:

AFA systems typically comply with the following standards:

* [https://en.wikipedia.org/wiki/[Comtrade |COMTRADE]] – IEEE C37.111 / IEC 60255-24: Standard format for transient data exchange

* IEEE C37.118 – Standard for synchrophasor measurements in power systems

* IEC 61000-4-30 – Power quality measurement methods

Line 69 ⟶ 78:

* Phasor measurement unit

* Condition-based maintenance

* [https://en.wikipedia.org/wiki/Electric_power_quality[Electric power quality|Power quality]]

* [[SCADA]]

* [https://en.wikipedia.org/wiki/SCADA SCADA]
