FDIR/FLISR
A key driver and measurement of utility effectiveness is in the reliability of power to its customers. As many faults on overhead distribution lines are transient in nature, reclosing at the substation and installation of mid-line reclosers./switches can improve a utilities SAIDI reliability index by up to 24%.
When permanent faults occur on overhead lines, having feeders with increasing degrees or automation can greatly enhance distribution grid reliability and reduce restoration of unfaulted segments from several hours to a few seconds or minutes. A key component of these automation schemes is intelligent controllers that can integrate with FDIR systems through sharing local information and accepting control commands.
Recloser Control
Robust Design
Based on GE Vernova's proven controller platform with tens of thousands of units installed globally, the Multilin DGCR undergoes extensive Accelerated Life Testing (ALT) and Highly Accelerated Life Testing (HALT) to validate accurate functionality under specified conditions and to ensure accurate performance in extreme operating conditions and harsh environments.
Modes of Operation
The Multilin DGCR Recloser controller provides two modes of operation:
- Remote mode
- Local mode
The Multilin DGCR recloser controller measures three phase voltages and currents, and based on the measurements, manages Auto-Recloser functionality:

DDFR - Legacy
Distributed Digital Fault Recorder
Data Recording
Key Features
- Retrieves and Archives Transient Fault Records, Sequence of Event Records, and Disturbance Records recorded in protection relays distributed across the substation
- Automatically merges Events recorded in protection relays distributed across the network into a single substation wide Sequence of Event Record
- Stores months of fault and disturbance records internally, facilitating local substation analysis
- Discrete second Ethernet port will allow isolation between the network LAN and the IED’s connected to the DDFR.
Data Recording
The DDFR will detect that new information has been recorded in a relay and automatically retrieve and archive this data. Information that will be archived from protection relays include:
- Transient Fault Records
- Sequence of Event Records
- Disturbance Records
The DDFR is a Transient Fault, Sequence of Event, and Disturbance record archiving system that will seamlessly make available all of the recorded power system information necessary for performing post mortem fault and disturbance analysis.
Sequence of Event Record (SOE)
The DDFR will retrieve the Event Records stored in protection relays distributed across a substation and merge all of these Events into a Station-Wide Sequence of Event Record. Connecting the protection relays to an IRIG-B time clock will synchronize the relay internal clocks with 1 millisecond accuracy and enable the DDFR to create a Station-Wide Event Record that will be an exact representation of the sequence of operations that occurred in the substation.
Sequence Of Event Records (SOE)
Transient Fault Records
Transient Fault Records (also known as Oscillography records) that are recorded in protection relays will be retrieve by the DDFR and stored in its internal memory space. All Transient Fault Records will be archived using a naming convention that will make it easy for users to relate the Transient Fault records with a particular substation fault. Each record will be stored with a name that includes the exact date and time that the record was initially triggered. If the Transient Fault record was originally recorded in the relay as a COMTRADE file, the DDFR will store this record in its native format; if the protection relay stores it’s record in another format, such as a CSV file, the DDFR will automatically convert this file into the COMTRADE-1999 format so that the record can be analyzed using a standard COMTRADE viewer.
Disturbance Records
Protections relays that are capable of recording Disturbance Records that are used for analyzing extended or evolving power system disturbances such as Voltage Sags or Swells will be retrieved and archived be the DDRF. All Disturbance Records will be archived using a naming convention that will make it easy for users to relate the Disturbance records with a particular power system disturbance. Each record will be stored with a name that includes the exact date and time that the record was initially triggered. Disturbance records will be stored in COMTRADE format and if needed, first convert this file to a COMTRADE file from its native format.
Key Features
- Effortlessly archives recorded data to a permanent enterprise network location or server for remote investigation and analysis
- Non-volatile, solid state storage able to store months worth of fault and disturbance information locally inside the DDFR.
Entreprise Network Archiving
The DDFR Archiving System will automatically copy all data stored in DDFR’s located throughout a companies wide area network into a centralized network location allowing users to analyze fault and disturbance data without having to be at the same location as the DDFR. This DDFR Archiving System that runs on coma network PC or Server can retrieve data from multiple DDFR’s thereby creating a permanent enterprise wide library of all past disturbances on your power system. The information collected by the DDFR Archiving System will be categorized in separate directories for each DDFR, making it easy for users to identify data about faults and disturbances related to each individual substation.
Archive data collected in DDFR’s distributed across the network into a centralized, accessible network location
Viewing Archived Records
Users can analyze sequence of Event Records, Transient Fault Records, and Disturbance Records that have been stored on a DDFR or archived onto a network location by the DDFR Archiving System by using the EnerVista DDFR Setup Software. The DDFR Setup Software’s Event Record viewer and COMTRADE viewer can access archived records to provide local or remote analysis capability to anyone with access to network storage location.
Sequence of Event Viewer
The EnerVista™ DDFR Setup Software contains a Sequence of Event viewer that allows for easy analysis of the Events stored in the DDFR or archived to the network location. Each recorded event will contain detailed information including:
- Timestamp of Event
- Description of the Event
- Name of Substation
- Name of Source Relay
- Model of the Source Relay
The Sequence of Event viewer provides the ability to sort the recorded events by any of the available fields of information or to perform queries to show only the events that are necessary for troubleshooting a particular fault.
COMTRADE Viewer
The COMTRADE viewer that is included with the EnerVista DDFR Setup Software provides the ability of analyzing the Transient Fault Records and Disturbance Records that have been archived by the DDFR. This full featured COMTRADE viewer allows for analyzing records in a standard time based format that shows the magnitude of all measured quantities, or in Phasor diagram view that shows the magnitude and angle differences between any of the parameters. The COMTRADE viewer can also perform a harmonic analysis on all measured Phasor quantities and display the harmonic content for every point in the record up to the 25th harmonic.
Meet Standards DDFR Requirements
When used with advanced microprocessor based relays such as the UR family, the DDFR System meets or exceeds requirements of International Standards for Digital Fault Recording.
