M-6283 THREE-PHASE DIGITAL CAPACITOR BANK CONTROL
SUGGESTED SPECIFICATIONS
Pole-Top/Pad Mount Capacitor Bank Control, metering, and monitoring for the
Capacitor Bank shall be provided by a microprocessor-based package. The
microprocessor-based package shall be suitable for Pole-Top or Pad Mounted
Capacitor Banks, as well as Single-Stage Substation Capacitor Banks operating in
Non-Series configurations. The control shall have the following minimum
functional and behavioral attributes:
CONTROL FUNCTIONS
The capacitor bank control shall include the following features and can be used for either pole-top
or pad mounted capacitor banks as well as non-series, single-stage, substation banks where
SCADA communications are desired.
LOCAL AUTOMATIC CONTROL MODE

CAPACITOR BANK CONTROL OPERATION
Control Operating Characteristic: The capacitor bank-control shall have independent phaseswitching and the operating characteristic shall be configurable for classic voltage, adaptive
voltage, VArs, or current. The control’s configurable operating characteristic shall employ definite
as well as inverse timing and provide an adjustable bandwidth to optimize bank operation and
eliminate unnecessary switching. The configurable operating characteristic shall allow time and/or
temperature overrides. The selected operating characteristic shall have further user-configurable
selections to refine its switching decision.
SENSING MODES
Single-Phase Selection: This option will allow the user to choose which phase; A, B or C is used
as the controlling parameter. Once this is selected, the control will use that phase value in Classic
voltage control mode or Autodaptive® mode to make decision on how to regulate the load voltage.
The option is valid for all three methods of control namely Voltage, VArs and Current.
Three-Phase Average/Total: If three-phase average is selected the measured value of all three
phases shall be averaged and used as the Effective Bandcenter for operation and to make it’s
open or close capacitor bank switching decisions. When the control uses the VAr control
characteristic, the averaging shall be replaced by the total sum of the VArs of all three phases.
The CT multiplier shall be assumed equal when the VAr control method is selected. In Control
Mode Limits, the three-phase maximum and minimum voltage shall be used to evaluate userassigned voltage limit violations.
CONTROL MODES
Classic Voltage Control: Classic voltage control shall make its CLOSE and OPEN switching
decisions based on Control Close and Open Voltage settings and measured Line Voltage
conditions and Time and/or Temperature overrides when applied. The control Close and Open
Voltage settings shall apply based on the setting of the Control Phase Selection. Voltage
excursions beyond the set value for greater duration than the time-delay will result in appropriate
control operation on the affected phase.
Adaptive Voltage Control: Adaptive voltage control shall contain two control methods, Fixed or
Average.

The Fixed method shall provide means to establish a bandcenter setting for each phase
that the control uses for comparison to measured voltage to make CLOSE or OPEN
capacitor bank switching decisions on the affected phase.

The Average method shall monitor each phase independently and develop an Effective
Bandcenter based on a long-term average of the input voltage on that phase for
comparison to measured voltage to make CLOSE or OPEN switching decisions for the
capacitor bank on the affected phase.
VAr Control: VAr control shall make its CLOSE and OPEN switching decisions based on Control
Open and Close VAr settings compared to Line VAr conditions. The control shall monitor each
phase, and independently switch individual phase capacitor banks based on the individual phase
VArs. A single pair of Control Open and Close Time settings shall apply to all three phases and
VAr excursions that exceed the time-delay setting shall result in control operation on the affected
phase.
When the control uses the VAr control method, the VAr load shall replace the averaging on each
separate phase. The CT multiplier shall be assumed equal when the VAr control method is
selected. In Control Mode Limits, the maximum and minimum voltage shall be used to evaluate
user-assigned voltage limit violations.
Autodaptive Voltage Control method employs an inverse timer and bandwidth to optimize bank
operation, eliminating unnecessary switching, and allow application of Time and/or Temperature
overrides.
Page 2 of 10
File: 841002203
Automatic VAr Control Mode Option: This option allows the control to make its Open and
Close switching decisions based on measured line VAr conditions and Time and/or Temperature
overrides when applied. VAr excursions beyond the set value for greater duration than the time
delay will result in appropriate control operation. In addition, the control shall offer the option for
Line Post Current Sensor inputs to provide phase current measurement to the control.
Current Control: Current control shall make its CLOSE and OPEN switching decisions based on
Control Open and Close Current settings compared to Line Current conditions. The control shall
monitor each phase, and independently switch individual phase capacitor banks based on the
individual phase current. A single pair of Control Open and Close Time settings shall apply to all
three phases and current excursions that exceed the time-delay setting shall result in control
operation on the affected phase.
All Control Methods shall provide a Definite time-delay or an Inverse time-delay allowing faster
response for larger excursions while eliminating unnecessary switching. All Control Methods shall
provide a standard Instant Timer Reset or alternatively, an Integrating Timer Reset to facilitate
bringing the controlled parameter solidly back in band.
SCADA REMOTE MANUAL CONTROL MODE:
SCADA Remote Manual Mode: The IVVC algorithm residing at the Master Control Center of the
SCADA computer or other Host computer may use Remote Manual Mode for control. The control
shall be capable of operating from SCADA signals received through wired or wireless
communications media to command bank switches for OPEN and CLOSE operations. The cap
bank control shall maintain an Overvoltage and Undervoltage Limit supervision to protect the
“never to exceed” voltages set as standard by the utilities and SCADA shall be allowed to make
OPEN and CLOSE commands as necessary when operating within those safety limits. The cap
bank control shall provide a means to switch from Remote Mode to Automatic Mode if
communications fail and continue to operate autonomously until communications are restored.
The control shall provide contingency responses upon extended loss of communications.
The capacitor bank control shall utilize a SCADA integrity monitor (SCADA Heartbeat) as well as
additional means to monitor the on board communications module for loss of its own operation.
Either failure or loss of communications from master or from slave shall trigger the cap bank to
switch to Automatic operation. After communications are restored for a specified length of time,
the cap bank control shall revert to SCADA Remote Manual Control Mode. This may be done
automatically after a time-delay or as directed by SCADA Master.
SCADA Remote Manual Mode - SCADA Heartbeat: A SCADA Heartbeat Remote Mode shall
be provided as a means for the SCADA system to place the unit in Remote Operation to perform
Open and Close operations as directed by a central control source. This mode shall have a timer,
and as long as the Remote Timer setting in the control is refreshed by the SCADA system
receiving a valid DNP 3.0 command, and before timing out, the control shall remain in Remote
Manual Operation. If the delay times out, the control shall revert to Local Automatic Operation.
The Local Automatic Operation shall switch back to Remote Manual Operation upon receipt of a
valid DNP 3.0 command via SCADA.
SCADA REMOTE MANAGEMENT OF LOCAL AUTOMATIC CONTROL MODE:
SCADA Remote Management of Local Automatic Control Mode: The capacitor bank control
shall have the capability to allow Remote SCADA Management of Local Automatic Capacitor
Control. In this way, the Centralized Control can monitor cap bank controls allowing them to
operate autonomously and only controlling them directly when emergencies arise. Management
via SCADA or other Host computer capable of operating through wired or wireless
communications media allows SCADA to effect control by either changing the local automatic
control settings via analog signal or by sending binary commands for direct OPEN and CLOSE
operations. Sending analog settings to the control and letting it operate based on its new
Page 3 of 10
File: 841002203
marching orders instead of directing each open and close commands conserves bandwidth
substantially and thereby minimizes the communications burden and total cost of operation.
The control shall provide a SCADA Test Mode that blocks the unit’s physical outputs and
removes the reclose delay, that normally prevents a Close operation for a minimum of five
minutes after an OPEN. The control LEDs, front panel, and remote status indications shall still
indicate bank operations as if the outputs were not blocked to allow user verification of settings,
correct SCADA communications point mapping, and operation.
INSTALLATION CONFIGURATION SETTINGS:
VT Ratio Correction: The control shall provide VT ratio correction
Phase Shift Compensation: The control shall provide phase shift compensation correction when
in VAr or Current Control mode to correct for phase shifts normally encountered in line post
sensors, and when current information sources are located on phases other than the measured
voltage source.
Operations Counter: The control shall provide a software counter that increments by a
selectable X or 2X count for either a CLOSE or an OPEN operation.
Re-settable Operations Counter: The control shall provide a second software counter similar to
the operations counter that may be reset by the user.
COMMUNICATIONS
The communication ports shall provide access to all features, including metering, software
updates, and programming of all functions. This shall be accomplished using a modem or direct
serial connection from any PC-compatible personal computer running the control’s
Communications Software package or via SCADA communications software.
Communications Ports: Communication ports shall be optionally available in the following
forms:
 Ethernet 10/100 Mbps through a copper RJ-45 connection (100 Base-T)
 Ethernet 100Mbps Fiber Optic with ST connectors (100 Base-FX)
 Serial Ports with RS-485, ST or V-Pin Fiber Optics, or RS-232
Protocols: The control shall support the following standard protocols: DNP3.0 and MODBUS.
The USB port shall utilize MODBUS for local interface communications. The Ethernet port
supports DNP 3.0, MODBUS, and IEC 61850 protocols over TCP/IP.

File: 841002203
Advanced SCADA Communications:
True Ethernet
The control shall provide an imbedded, true 10/100 Mbps Ethernet, auto negotiable, capable of
supporting up to eight concurrent sessions and simultaneous multiple protocols with up to eight
sockets (concurrent sessions) open at a time. The eight sockets shall be capable of supporting
Modbus and DNP over TCP/IP and up to five of the eight sockets shall be capable of supporting
DNP 3.0. This requirement allows users simultaneous remote access to the control via the same
physical Ethernet port to view/change settings or retrieve data, without affecting the SCADA
communications.
Full DNP Implementation
The control shall provide full DNP implementation to support both report-by-exception and
unsolicited reporting within DNP 3.0 to aid in the reduction of bandwidth requirements. The
control shall also provide DNP File Transfer to permit the recovery of data logs and triggered
events, oscillography, and device discovery to facilitate setting up the integrated system.
In serial communication, the control shall have DNP addressing capability that allows networking
of multiple controls. The DNP implementation shall support the pre-defined global addresses
within DNP 3.0 and allow the user to define two additional global addresses. Each control shall be
able to be assigned a Device Address, Feeder Address, and Substation Address ranging from 1
to 65519. The control shall support broadcast commands from the master to all controls on the
network in order to allow some or all controls to act on one command at the same time. This
capability reduces bandwidth and is critical for rapid response to changing system requirements
with settings changes in multiple controls in selected zones. The control shall provide a
configuration program that allows any point to be mapped into any DNP location and allows
dummy filler points to be added to facilitate interoperability by replicating legacy vendor pointmaps to SCADA. This program shall also allow for individual point dead-banding and individual
point assignments into Class 1, 2, or 3.
Cyber Security
The control shall provide the following information security mechanisms when operating within
DNP:
 Permit multiple master source-address authentications, source-address validation, and
multilevel access codes logged with date and time, with DNP authentication using FIPS
180-2 Secure Hash Standard (SHA-1)

Trip and lockout occurs when voltage or current THD increases above the control’s THD
Trip Pickup setting
The control remains in Lockout and the THD Lockout Reset-Delay period begins only
after the THD decreases below the Voltage or Current THD Lockout Reset setting and
continues for the duration of the THD Lockout Reset-Delay setting; indicating THD was
above the THD Trip Pickup setting for a sufficient period to cause capacitor bank
resonance and possible explosion
The Trip and Lockout shall remain in effect only for the duration of the THD Lockout
Reset-Delay setting when the voltage or current THD levels drop below the THD Trip
Pickup setting within 1 second following the trip; indicating the capacitor bank was part of
the L/C system circuit and functioning as the filter, partially sinking the harmonics
Lockout/Reset Operations Counter: The control shall have an internal counter that increments
each time the following sequence occurs:
