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.
Switch Control
Robust Design
Based on GE's proven controller platform with tens of thousands of units installed globally, the Multilin DGCS 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 DGCS Switch controller provides two modes of operation:
Remote mode
Local mode
The Multilin DGCS switch controller measures three phase voltages and currents, and based on the measurements, manages Auto-Sectionalizing functionality:
Key Features
Multiple setpoint groups
Expandable inputs and outputs for advanced applications
Customized automation schemes using FlexLogic™
Automation & Control
The Multilin DGCS offers powerful I/O and programmable logic (FlexLogic™) options for advanced automation and control, reducing the need and costs associated with additional programmable controllers or discrete control devices.
Remote Control
For both operational efficiency and reliability reasons, the Multilin DGCS provides remote control for operating switchgear. The Multilin DGCS is capable of providing both local and manual control of the switchgear.
Set Point Group Control
The Multilin DGCS has three identical set point groups. The activation of the group can be done either from the HMI or via a digital input.
Virtual Inputs and Outputs
The Multilin DGCS provides 32 virtual inputs and 32 virtual outputs that provide users with the ability to send commands to the device. The Multilin DGCS can accept commands from SCADA, through the front HMI, or front USB port to issue commands such as close or open.
Command Setting
The Multilin DGCS has the ability to force commands from the menu structure. This can also be achieved via the EnerVista™ software that runs on a PC. This simulation ensures that the close and open commands can be safely issued from a distance without using the HMI.
FlexLogic™
FlexLogic in the Multilin DGCS provides the ability to create customized control schemes. This minimizes the need and costs associated with auxiliary components and wiring
