Volt/VAR control
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.
Voltage regulator control
Robust Design
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.
Mode of Operation
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
Manual Mode – Local Control
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.
Manual Mode – Remote Control
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.
Automatic Mode
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.

The Multilin Capacitor Bank Controller utilizes industry standard, communications technologies making it one of easiest and most flexible controllers to use and integrate into new and existing SCADA or DMS infrastructures. Supported communication protocols include:
- DNP 3.0
- Modbus RTU (RS485)
Multiple communication ports and protocols allow for remote control and easy access to device and system information. All communication ports are capable of simultaneous communications. The Multilin Capacitor Bank Controller can also communicate to Volt/VAR or SCADA systems via wireless communications media. The supported wireless media includes:
- Wireless Radio (MDS or customer specific)
- GSM/GPRS
- Pre-wired for future radio
Front Panel
Front Panel Quick Keys
Front Penel quick keys provides direct access to key individual setting parameters
Key Features
4-Level device security to maintain authorized access only
Simplified device configuration software tool and industry leading suite of software tools to manage and maintain Multilin devices.
Security
The Multilin Capacitor Bank Controller and associated software tools provide a suite of security features that ensure only approved personnel can make changes to the configuration of the system or execute commands. These functions enable a utility to meet NERC/CIP requirements.
Password Security
The Multilin Capacitor Bank Controller offers multiple levels of password security to limit access control based on settings or command levels. There are four levels of password security provided:
- Local Settings Access
- Local Control Access
- Remote Settings Access
- Remote Control Access
Local Access refers to users making changes using the front USB serial port and the HMI. Remote Access refers to users making changes using the rear RS485 port.
EnerVista™ Software
The EnerVista™ Suite is an industry-leading set of software programs that simplifies every aspect of using the Multilin Capacitor Bank Controller The EnerVista™ suite provides all the tools to monitor the status of the protected asset, maintain the controller, and integrate information measured by the DGCC into SCADA or the DMS monitoring systems. The ability to easily view sequence of events is an integral part of the setup software, as postmortem event analysis is critical to proper system operation.
