Voltage regulator controllers and Capacitor bank controllers can operate as part of an integrated Volt/VAR Control (IVVC) scheme or as a Centralized Volt/VAR control (CVVC) system. The IVVC or CVVC system works to achieve two key objectives:
Optimize Voltage - through ‘Conservation of Voltage’ that leads to reduced demand, that may result in decreased generation up to 6%.
Increased efficiency- through improved power factor and reduced VAR which helps to reduce power line losses.
Based on GE Vernova’s proven controller platform with tens of thousands of units installed globally, the Multilin Voltage Regulator Controller underwent 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.
To provide optimal application flexibility, the Multilin Voltage Regulator Controller offers two modes or methods of operation in which the device can be implemented to control the voltage regulator: a) Manual Mode (Local Control or Remote Control). b) Automatic Mode
In this mode, it is possible to Raise or Lower the tap locally from the Push buttons that are available on the front panel of the Multilin Voltage Regulator Controller. For added operational reliability and operator safety, inhibit functions configured in the unit continue to operate as defined.
In this mode, the commands for Tap Raise and Lower are received from SCADA or the Integrated Volt/VAR systems via communications. This communications channel can be provided via optional radio or cellular communications.
In automatic mode, the Multilin Voltage Regulator Controller compares the measured voltage to the set voltage level, and if the difference exceeds the set bandwidth (voltage limits), the Multilin Voltage Regulator Controller issues a Raise or Lower tap commands to maintain the desired voltage levels.

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.
