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.

Robust Design
As a complete package, the Multilin Capacitor Bank Controller is offered in a NEMA-4 certified cabinet that is suitable for operation of harsh environments with an operating range of -40°C to + 60°C (-40°F to +140°F).

Mode of Operation
To provide optimal application flexibility, the Multilin Capacitor Bank Controller offers two modes or methods of operation in which the device can be implemented to control the Capacitor Bank:a) Manual Mode (Local Control or Remote Control). b) Automatic Mode

Manual Mode – Local Control
In this mode, it is possible to Open or Close the Capacitor Bank, locally, from the large pushbuttons located on the front panel of the Multilin Capacitor Bank Controller. For increased operational reliability and operator safety, inhibit functions configured in the unit will continue to operate as defined.

Manual Mode – Remote Control
In this mode, the commands for Open or Close of the Capacitor Bank are received via communication channels from the SCADA or an integrated Volt/VAR system. This communication channel can be provided via optional radio or cellular communications.

Automatic Mode
In automatic mode, the Multilin Capacitor Bank Controller issues commands to Open or Close the Capacitor Bank. In this mode, the Capacitor Bank is controlled

Key Capacitor Bank Control Features:

Four Season Configuration
Time Schedule Control
Temperature control
Voltage control
VAR Control (Min Delta KVAR)

	Star Neutral Overcurrent (Blown Fuse Indication) Customized automation schemes using FlexLogic™ Expandable inputs and outputs for advanced applications

Reverse Power Detection
The Multilin Capacitor Bank Controller includes a Reverse Power Detection function, which defines the minimum pickup required to detect reverse power conditions.

Neutral Overcurrent Protection (Blown Fuse Condition)
In situations where the capacitor bank has been tripped due to a neutral current unbalance situation, the Multilin Capacitor Bank Controller will execute a reclose action to validate the state of the fault, ensuring the fault was not transient in nature. This automatic reclose action ensures maximizes system reliability.

The Multilin Capacitor Bank Controller offers powerful I/O and programmable FlexLogic™ options for advanced automation control, reducing the need for additional programmable controllers or discrete control relays. The Multilin Capacitor Bank Controller has three identical set point groups. The activation of the group can be done either from the HMI or via a Digital Input.

Set point group control
The Multilin Capacitor Bank Controller 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 Capacitor Bank Controller provides 32 virtual inputs and 32 virtual outputs that provide users the ability to send commands to the device. The Multilin Capacitor Bank Controller can accept commands from SCADA, through the front HMI, or front USB port to issue commands such as Open or Close.

Command Setting The Multilin Capacitor Bank Controller has the ability to force commands from the menu structure accessible through the Multilin EnerVista setup software that runs on a PC.

FlexLogic™ Advanced FlexLogic in the Multilin Capacitor Bank Controller provides the ability to create customized control schemes. This minimizes the need for auxiliary components and wiring, thus reducing complexity and costs.
