Introduction

Description of the Capacitor Bank Controller

The capacitor bank controller is a replacement for standard,
fixed-function capacitor controllers currently on the market. The
controller consists of standard, off-the-shelf, Allen-Bradley hardware
with the application ladder code necessary to perform power factor
correction. The controller is designed to provide the same base
functionality as a fixed-function capacitor bank controller. Also, you
may add additional code to the controller to fit its functionality to
special circumstances.

The capacitor bank controller is a pre-engineered control system
containing a MicroLogix 1500 controller, a standard data access
terminal (DAT), one or more Powermonitor 3000 modules, and an
optional additional human-machine interface (HMI). Pre-engineered
ladder logic code in the controller gathers real and reactive power
data from up to four power feeds (utility feeds and/or generators).
The logic operates on the data in standard engineering units of kVAR
and kW and acts to minimize imported and exported reactive power
by switching up to 10 steps of capacitance. This strategy controls
power factor while reducing the likelihood of voltage surge caused by
excessive kVAR export.

Functions

• Auto configure

• Manual configure

• Discharge timer on each step

• Selectable operating modes

– Manual operation
– Linear, last-in, first-out
– Balanced, level-out usage of capacitor steps

5. Connect the MicroLogix 1500 controller to 120V ac control

power, earth ground, capacitor step contactors (or interposing
relays as required), and an alarm circuit as shown in the wiring
diagram.

Wire the Controller

Fault-protection relays can be used to immediately discharge all or
specific capacitor steps during a fault occurrence. Input 0 is wired to a
normally closed fault-protection relay and discharges all capacitor
steps during a fault occurrence (low-state condition). Inputs 1… 10
are wired to normally closed fault-protection relays, and discharges its
respective capacitor step during a fault occurrence (low-state
condition). If fault protection is not being used for a specific capacitor
step, then that respective input is wired closed using the controller
supplied 24V dc power.

A normally-open momentary pushbutton is wired to Input 11. This
pushbutton is used to reset the controller after a fault occurrence.

Fault Relay Power

Installation 13

Output 0 is used as an alarm relay and is wired normally open to an
external alarm indicator. Output 1…10 is wired to normally-open
contactors for each respective capacitor step.

20 Installation

Configuration

The capacitor bank controller base unit has been set up to require
minimal out-of-box configuration.

The base system has default communications settings. Certain
circumstances and options require additional configuration of
communications, which may include the use of programming software
not included with the controller.

You are required to configure the Powermonitor meters to coordinate
them to the power circuit in the base unit and all options.
Configuration of the Powermonitor meter is performed using the
display module.

The controller requires configuration to coordinate it to the number
and size of steps that exist in the capacitor bank being controlled, as
well as the desired operating mode and other selections. Use the data
access terminal (DAT) or the optional PanelView 550 operator
terminal to configure the controller.

ATTENTION

Do not operate the capacitor bank controller without first

Ethernet HMI Option

This option allows the PanelView 550 terminal to connect to your
Ethernet network. It obtains data from the MicroLogix 1500 controller
through an Ethernet interface module and your local area network.
The MicroLogix 1500 controller obtains data from the Powermonitor
meters through its Channel 1 serial port, in the identical way as the
base unit and serial HMI options.

Default communications settings are factory configured.

To change from the default Ethernet addresses, additional software is
required.

The ENI Utility is a free download used to configure the Ethernet
interface module.

The ENI Utility can be found at:
http://www.ab.com/micrologix. Follow the links to Get Software and
EtherNet/IP and DeviceNet Interface Configuration Utilities.

For information on using the ENI utility, please refer to Rockwell
Automation Knowledgebase article A19540 - Quick Start -- Getting
started with using the ENI Utility.

You need to supply 24V dc power to the Ethernet Interface while
using the ENI utility since the cable to the MicroLogix 1500 controller
is disconnected. After reconfiguring the Ethernet address, cycle power
to the Ethernet interface module.

Publication 1413-UM001C-EN-P - May 2006

Changing from the default addresses in the Powermonitor meters must
be done using the Powermonitor display module.

Refer to Powermonitor Meter Configuration on page 23.

Changing the PanelView 550 communications settings requires the use
of PanelBuilder32 software, which is purchased from your local
Allen-Bradley representative or distributor.

Additional Powermonitor Meters Option

The capacitor bank controller base system and HMI options provide
for the addition of up to three more Powermonitor meters. The
MicroLogix 1500 controller logic is designed to communicate with
Powermonitor meters that have the following communications
settings. If Ethernet Powermonitor meters are added to the system,
their Ethernet addressing should be configured per your networking
requirements.

Use the DAT for Configuration

The data access terminal (DAT) provides a basic configuration
interface for the capacitor bank controller. In Integer mode, the DAT
provides read/write access to the configuration parameters listed in
the Control and Status Parameters table. You may also use the DAT in
Bit mode to automatically detect and configure the capacitor-bank
step sizes.

The DAT enters the Bit mode automatically after applying power. Bit
mode can also be selected by pressing the BIT key. If Bit mode was
already active, the DAT displays the last bit element monitored. If
Integer mode was active, the DAT displays the first bit element, after a
brief delay during which a working message appears.

To select Integer mode, press the INT key. If Integer mode was
already active, the DAT displays the last integer element monitored. If
Bit mode had been active, the DAT displays the first integer element
after a brief delay during which a working message appears.

Auto-configure Capacitor Step Sizes

Use the DAT to automatically configure the step sizes.

1. Select Bit mode.

2. Scroll to and select bit 40.

3. Press the Enter key to edit the bit.

4. Use the up/down key to change the value of the bit to 1.

TIP

If the data is protected or undefined, pressing the
up/down key scrolls to the next data element.

5. Press the Enter key to store the new value.

Esc or INT/Bit keys discard the new value.

Publication 1413-UM001C-EN-P - May 2006

32 Installation

The auto-configure process begins. During this process, the controller
energizes each capacitor-bank step for a short time, measures the
steps kVARs and records the value. This process repeats several times
and the results of each trial are averaged. When the process is
complete, the averaged values are copied to the Effinal_StepSize_Sn
parameters and the Auto_Detect_Cap_Size flag is reset.

You must manually configure any parameters that need to change
from the default values listed in the table.

Input Interlock Mode

The Input Interlock mode allows fault protection for each capacitor
step through the use of fault-protection relays. Wire normally closed
fault-protection relays to each input from 0…10 of the controller. Wire
a normally-open momentary pushbutton to Input 11. This pushbutton
serves as a reset button.

During a fault occurrence, the controller discharges and locks-out the
respective capacitor step associated with the fault relay that tripped.
The fault-protection relay wired to Input 0 discharges and locks-out all
capacitor steps. The remaining fault-protection relays discharge and
lock-out their respective capacitor step (that is, Input 1 discharges and
locks-out capacitor step 1).

In order to place a capacitor step back into the sequence, a fault must
not be present for that step, and a reset must be initiated by pushing
the Reset pushbutton.

Manually Set Configuration Parameters

Use the DAT to manually change the controller configuration
parameters.

1. Select Integer mode.

2. Scroll to and select the desired configuration parameter.

Refer to the Control and Status Parameters table on page 27.

3. Press the Enter key to edit the parameter.

Introduction

The capacitor bank controller gathers real- and reactive-power data
using one or more Powermonitor meters. The processor manipulates
data in engineering units of kVAR and kW. The unit does not directly
control power factor, but rather works to actively minimize imported
and exported kVAR. The net result of this philosophy indirectly
controls power factor and minimizes voltage excursions associated
with excessive kVAR export.

The capacitor bank controller can accommodate up to four different
utility feeds and/or generators. Each feed requires an individual
Powermonitor meter. The unit sums the kW and kVAR readings from
each of the Powermonitor meters to arrive at an aggregate kVAR so
that a single capacitor bank could be used to compensate several
feeds simultaneously.

The traditional C/k ratio is not required for the capacitor bank
controller since we are working in engineering units within the
processor.

Aggregate Power Factor is calculated and displayed using the
following formula:

The Powermonitor meter data is gathered with RS-485 ports using the
DF-1 half-duplex protocol at a data rate of 19.2 Kbps.

Operating Modes

37 Publication 1413-UM001C-EN-P - May 2006

Each capacitor step can be individually selected to on, off, or auto
status. The capacitor discharge-timer interlock is in effect in Manual
mode to prevent capacitor bank damage. In Auto mode, a step is
available to any of the automatic sequences described below. In the
On or Off mode, a step is unavailable to any automatic operating
mode.

• Manual (mode = 0) – This mode disables all automatic

operating modes.

Manual mode is the default configuration. All capacitor steps
have a default configuration of auto.

38 Operation

• Linear (mode = 1) – This mode of operation switches the

capacitor steps on and off in first-in, last-out (FILO) order. That
is, the first step on is the last step turned off. This is most useful
when all the capacitor steps are of similar sized.

• Balanced (mode = 2) – This mode counts the number of

opening operations on each capacitor step and switch-capacitor
steps to balance the number of opening operations equally
across all of the employed capacitor steps. This mode is also
most useful when all of the steps are of similar size.

• Best Fit (mode = 3) – This mode selects capacitor steps to be

switched on and off to most closely achieve the target power
factor and kVAR needs of the system. When the system’s kVAR
needs increase, the available step or steps with the closest
(aggregated) kVAR rating is added. On decreasing kVAR
demand, steps are switched off in similar fashion.

• Special (mode = 4) – This mode is reserved for

customer-defined switching sequences not described above
including voltage, current, and time of day type functions.
Special-switching mode might include switching on parameters
such as PF, current, voltage, time of day, weekends / weekdays,
or seasonal adjustments.

CTPT Modes

Refer to Add Special Functionality on page 51.

• %THD (mode = 5) – This mode selects capacitor steps to be

added in a linear fashion (for example, step 1, step 2) until the
%THD_V is below the setpoint for a user-configurable time
delay (default 60 seconds). The system will start to remove
capacitor steps when the %THD_V is 1% below the setpoint for
the user-configurable delay.

The CTPT mode configures the capacitor bank controller to be
connected to current transformers (CTs) and potential transformers
(PTs) in one of three ways:

• 0 = Normal mode - CTs and PTs are installed in a typical
three-phase configuration. The controller uses the real- and
reactive-power data produced by the power monitor(s) without
further processing.

• 1 = NEU mode - One CT wired on the A phase and one PT
wired from phase A to neutral are installed on a three-phase
circuit. The power monitors must be set up in Wye-wiring mode.
The controller multiplies the real- and reactive-power data
produced by the power monitors by 3.

• 2 = Retro mode - One CT wired on the A phase and one PT
wired from phases B to C are installed on a three-phase circuit.
The power monitors must be set up in Wye-wiring mode. The
controller swaps the values of the real- and reactive-power data

produced by the power monitors and multiplies them by .
This mode is particularly useful in retrofit applications.

Alarms

• Bad Step - This alarm indicates a blown fuse and/or loss of
capacitor condition. The controller measures actual VAR output
from a capacitor step, averages, and compares this value with
the original effective capacitor value. When actual VAR is more
than the user-configurable StepKvarTolerance (default 5%)
below the effective step size for a user-configurable delay
(default 30 seconds), the alarm is activated. The alarm is reset
when actual VAR output is greater than or equal to the setpoint
for the same delay. The step will be latched as tripped/offline if
the VAR output falls below 90% of nominal.

• Target power factor not achieved - If actual power is less than
setpoint for a user-adjustable number of seconds, then set the
alarm flag.

• High and Low Voltage - If BusVolts is outside either limit, this
alarm is activated immediately. After the voltage returns to the
proper range for a configurable amount of time, this alarm is
reset.

• %THD_V above setpoint - If all available steps are added and
%THD_V remains above the setpoint longer than the
configurable time delay, an alarm will be generated and the
system alarm contact closes. The alarm is reset when the
%THD_V falls below setpoint for the same period of time.

• Unbalance - This alarm is set when the average neutral current
exceeds a preset maximum for a configurable period of time. It
is reset using the same timer.

Operator Interface

The capacitor bank controller offers three types of operator interface.

• Data access terminal (DAT) – A simplistic operator terminal
physically attached to the controller that provides read/write
access to configuration and operating data. The DAT is provided
with the base unit and all optional configurations.

• Serial PanelView 550 – A comparatively robust operator
interface terminal that provides selectable configuration and
operating screens and a keypad for navigation and data entry.
Communications with the controller is through a serial
point-to-point connection. The serial PanelView is offered in the
Serial HMI option only.

• Ethernet PanelView 550 – A similar HMI to the serial

PanelView but using Ethernet communications, offered with the
Ethernet HMI option only.

Data Access Terminal (DAT)

The data access terminal (DAT) provides access to 48 integer and 48
binary data registers.

The Binary (bit) Elements and Integer (Word) Elements tables define
how these register assignments are made.

Add Special Functionality

For added functionality, custom ladder-logic programming and
hardware integration are permitted, however, strict guidelines must be
followed to comply with warranty contracts.

• Altering of existing ladder-logic code is prohibited and will void
all warranty contracts.

• Additional functionality can only be implemented by adding
additional ladder logic code to subroutine PFMGR4.

• Additional subroutines may be written, but must be called
through PFMGR4.

PFMGR4 Logic

The following sections provide details of PFMGR4 ladder-logic
programming.

Overview

There are three basic sections to PFMGR4:

• Power factor alarm

The power-factor alarming section specifies whether your
system KVAR is within its specified range and how long to wait
before alarming when it is out of range.

• Step control

The step control section specifies when to actuate or trip a step.

• Step routine

The step routine section specifies what step should be actuated
or tripped.

51 Publication 1413-UM001C-EN-P - May 2006

52 Add Special Functionality

Power Factor Alarm

The ladder logic code for this section has already been written. The
following is an explanation of the ladder logic code for lines one
through four.

If BUS_NET_KVAR (F8:2) falls outside of the limits defined by
KVAR_Lag_DB (N7:35) and PFMGR4_LEAD_DB_NEG (N94:0), then
the timer PF_INRANGE__TIMER_4 (T93:0) will be started. The default
time for this timer is 60 seconds. When this timer is done timing, it will
latch KVAR_NOT_ACHEIVED (B56:2) and reset the timer.

If BUS_NET_KVAR (F8:2) is within the limits defined by
KVAR_Lag_DB (N7:35) and PFMGR4_LEAD_DB_NEG (N94:0), then
reset PF_INRANGE__TIMER_4 (T93:0) and unlatch
KVAR_NOT_ACHEIVED (B56:2).

The above process sets the flag, KVAR_NOT_ACHEIVED (B56:2),
which indicates when the system KVAR is out of your specified limits.
This flag is used for HMI alarming.

Step Control

The step control consists of three parts. Part 1 specifies under what
conditions to tell the system that a step is waiting to be actuated or
tripped. Part 2 specifies under what conditions to tell the system that a
step should be actuated. Part 3 specifies under what conditions to tell
the system that a step should be tripped.

The following ladder logic examples are recommended formats for
your custom coding.

Part 1

If PF_INRANGE__TIMER_4 (T93:0) is done timing

• If PF_LEADING (B3:6/6) is high, and under any user-defined
conditions, latch KVAR_LAG_WAIT_2_ADD (B56:0/8).

• If PF_LAGGING (B3:6/7) is high, and under any other
user-defined conditions, latch KVAR_LEAD_WAIT_2_TRIP
(B56:0/7).

Part 1 should be implemented at line three in parallel with the outputs
of that rung.

Publication 1413-UM001C-EN-P - May 2006

See Part 1 Example.

Part 1 Example

Add Special Functionality 53

Part 2

If KVAR_LAG_WAIT_2_ADD (B56:0/8) is high and
TOTALSTEP_AVAL_AUTO (N70:31) is greater than 0, then output
energize KVAR_LAG_ADD_STEP (B56:0/4) and unlatch
KVAR_LAG_WAIT_2_ADD (B56:0/8). This will actuate the required
step defined by the step routine.

See Part 2 Example.

54 Add Special Functionality

Part 2 Example

Part 3

If KVAR_LEAD_WAIT_2_TRIP (B56:0/7) is high and STEPS_REQUIRED
(N7:58) is greater than 0, then Output Energize
KVAR_LAG_TRIP_STEP (B56:0/3) and unlatch
KVAR_LAG_WAIT_2_ADD (B56:0/7). This will trip the required step
defined by the step routine.

See Part 3 Example.

Part 3 Example

Step Routine

This section defines what step to use or trip. The outputs for the Step
Routine are USE_STEP_NUM (N58:1) and TRIP_STEP_NUM (N58:0).
When a step is controlled to be used, the step equal to the value in
USE_STEP_NUM (N58:1) will be actuated. When a step is controlled to
be tripped, the step equal to the value in TRIP_STEP_NUM (N58:1)
will be tripped.

Glossary

Bank

An overall capacitor or tuned-filter assembly. This controller is
designed to manage and control one bank consisting of 10 steps.

Instance

An instance of an object represents a complete iteration of an object
and all of its attributes and methods. For example, the vacuum switch
describes a typical vacuum switch. Each physical switch would result
in one instance of a vacuum switch object. Each instance of an object
must be managed independently in the software.

PM

See Powermonitor meter.

Powermonitor meter

The power measuring device located at the plant mains. There may be
more than one Powermonitor meter in a system depending on the
number of electrical feeds into the plant.

Step

A single switched circuit in a capacitor or filter bank. There are up to
ten steps in a bank. Others in the industry may also refer to these as
stages.
