General description of system with Bank
Controller
NOTE:
The "Bank controller" is a firmware branch for InteliSys NT controllers (any of it‘s hardware modification). For
more details about the available Firmware, Hardware and Archive file consult this chapter.
NOTE:
In the role of “MINT” controller the InteliGen NT or InteliSys NT controller with appropriate Firmware and
Archive must be used. For more details consult this chapter.
The "Bank controller" concentrates group of gen-sets, equipped with IG-NT or IS-NT MINT application, so
that from the outside point of view the group behaves as one large gen-set. Bank controllers can be
connected together so that large "tree-style" multisites (power stations) can be created. The aim of the Bank
controller is to overrride the limit 32 controllers on the CAN-2 bus.
TREE-STYLE POWER STATION
Several important notes to the tree-style structure:
•One bank can contain up to 31 controllers. Address 32 is reserved for the Bank controller itself.
•It is possible to connect up to 32 banks together.
•Load sharing, VAR sharing and shared peripherial modules do work over the whole multisite.
•Power management works among all the gen-sets in the system to ensure the equal run hours and
the most efficient combination of running gen-sets to cover the actual load demand and the
requested load reserve.

Installation
NOTE:
InteliGen NT or InteliSys NT controller (any of their hardware modification) equipped with the "IGS-NT-LSM-
PMS" dongle and programmed with IG-NT-BC or IS-NT-BC firmware must be used at the place of the Bank
controller.
NOTE:
It is not possible to monitor the whole multisite using one InteliMonitor. Each CAN bus must be monitored
separately.
CAN bus wiring
CAUTION!
Each controller in one segment of the CAN bus must contain unique controller address!
Inter gen-set controller CAN (CAN-B)
The Bank controller is connected with the gen-sets inside the bank via the CAN1 interface. That means
although the gen-set controllers are connected to the intrabank bus via their CAN2 interface the bank
controller uses CAN1 instead. The bank controller has fixed address 32, so gen-set controllers can use
address 1-31. See the Figure: CAN bus wiring.
NOTE:
The gen-set controller is never connected directly to the CAN-A but it has to be always subordinated to
some BankController.
NOTE:
The request of the Bank Controller to run it´s subordinated gen-sets is distributed internally via CAN-B as
internal command Syst start/stop. It is not needed to be configured in the subordinated gen-set.
Interbank CAN (CAN-A)
Bank controllers are connected together via their CAN2 bus. The interbank bus can also contain InteliMains-
NT controllers. Address of the bank controller is adjusted by the setpoint Comm Settings: Controller Address.
NOTE:
It is not possible to use any peripherial module at CAN1 interface of the bank controller.
NOTE:
It is not possible to use InteliMains-NT controllers within the bank. The bank must contain only InteliGen NT
or InteliSys NT controllers with standard firmware and special “MINT-BC” archive.
NOTE:
The general rules for CAN bus wiring remain valid, i.e. the total length of the CAN bus must not exceed
200m (250kbps) or 800m (50kbps).

Figure: CAN bus wiring
Power lines wiring
The wiring of the power lines can be carried out in two ways.
1. One large common bus to which all gensets connect directly.
2. Separated bank buses connected to the common bus via Bank circuit breakers (BCB). In this case
the bank controller first starts the bank and when it is running the bank controller synchronizes the
bank to the common bus. This option is reccommended to be used whenever it is possible.
CAUTION!
Feeders and/or mains inlets must be connected to the common bus only. There must not be any load
connected to the intrabank bus.
If the function LBI: BCB feedback is configured at some input the controller assumes the BCB is used. If this
function is left unconfigured then connection without BCB is assumed.

AC measurement
The wiring of AC measurement depends on the type of wiring of the power lines (see Power lines wiring
paragraph above). If BCB is used following AC values are to be measured:
•Bank bus voltage, 3phase, required
•Common bus voltage, 3phase, required
•Bank current, 3phase, recommended
Following AC values are to be measured in systems without BCB:
•Bank bus voltage, 3phase, recommended
•Bank current, 3phase, optional

BCB control and synchronizing
If the system is equipped with BCB the BCB is controlled by the Bank controller. There is a set of control
outputs for various types of the breaker or contactor: BCB close/open, BCB ON coil, BCB OFF coil, BCB UV
coil. Breaker feedback signal is to be connected to the binary input with logical function BCB feedback. If this
logical function is not configured on any binary input the bank controller assumes BCB is not used. See the
chapter Installation for information about proper wiring of the site with or without BCB.

BCB can be closed to the common bus as soon as all the available gensets in the bank are running. If there
is countervoltage on the common bus the breaker is synchronized, otherwise it is closed to the dead bus.
In automatic mode the breaker is controlled automatically, in manual mode by the button on the controller
front panel or InteliVision.

Functions
OFF-MAN-AUT mode
OFF mode
The bank (gen-sets inside the bank) cannot be started. If START,STOP,BCB ON/OFF buttons are pressed
the controller will not respond.
When the gen-set inside the bank are running it is not possible to switch directly to OFF mode. First you
have to stop the bank.
MAN mode
1) START –Activates the internal signal Sys start/stop and causes start of the gen-sets inside the bank.
2) GBCB ON/OFF
If the bank bus bar voltage is out of the limits (adjusted in the setpoint group Gener protect) controller
does not respond to the BCB ON/OFF
a) controller closes BCB to dead bus.
b) controller starts BCB synchronizing when bus voltage is OK and MCB is closed or when other
bank provide healthy voltage to the bus. Closes the BCB when synchronized and stays running
in parallel (island or mains parallel).
c) Unloads the bank and opens the BCB if the bank was running in parallel to the mains or to other
banks.
3) STOP
a) When bank is running in parallel to other banks or the mains: transfers the load to the mains or
to other banks, opens BCB (internal signal Sys start/stop is deactivated and the gen-sets inside
the bank are going into cooling state and then are stoped).
b) When bank is running in single island (or in general there is no mains and no other bank to take
over the load to): opens BCB (internal signal Sys start/stop is deactivated and the gen-sets
inside the bank are going into cooling state and then are stoped).
AUT mode
1) When the LBI: Sys start/stop (at the Bank Controller) is activated, only the subordinated gen-sets
necessary to cover the actual load and requested load reserve are started (setpoint Powermanagement:
Pwr management is set as ENABLED. The power management can be based on kW, kVA or on relative
% reserve. The start of the bank is:
a) 1 sec delayed when MCB FEEDBACK binary input is closed (mains parallel)
b) delayed #SysAMFstrt del when MCB FEEDBACK binary input is opened –start to island parallel
(multi AMF) situation
2) The first bank closes the BCB to the dead bus (if the system with BCB is used), the rest are
synchronized to the bus as soon as at least subordinated gen-set in the bank closes it´s GCB and
energizes the bank powerline.
3) When all necessary gen-sets are connected to the bus and LoadRes strt is achieved, SYST RES OK
output is closed. Output could be used to close the MGCB (Master GCB).
4) Total load and power factor are shared between parallel operating gen-sets.
5) Close input LOAD RESERVE 2 (or 3 or 4) and use setpoint LoadRes strt2(or 3 or 4) to switch to another
load reserve setting. E.g. high load reserve during system start to be able to switch-on big devices, then
during normal operation lower reserve to save engines (and fuel).
6) If total load increases and selected LoadRes strt is no more fulfilled, after a Next start del next ready
gen-set with the highest priority (lowest priority number) is started and synchronized to the bus.
7) If load decreases and selected LoadRes stp is exceeded, after a Next stop del the running gen-set with
the lowest priority is unloaded, got off line, cooled and stopped.
8) Complete gen-sets group stops when binary input SYS START/STOP opens. If the input MCB
FEEDBACK is closed (gen-sets are in parallel to mains) controllers softly transfer the load to the mains.
When gen-set is unloaded (see GCB open level or GCB open del) opens the output GCB
CLOSE/OPEN.
9) The Running hours balancing or Load demand engines swap can be activated in power management.

HINT:
It is strictly recommended to operate all Bank Controllers and even all subordinated gen-set controllers in
AUT mode to allow all the function like power management to be performed to ensure the moste efficient
running of the system and run hours equalization across the whole installation.
NOTE:
If the wiring without the BCB is used the gen-sets are connected or synchronized to the common bus bar
(power line) directly like in the standard MINT application.
Active and Reactive Power control in the system with Bank Controller
NOTE:
The active and reactive power of the system is controlled by the Bank Controller (the gen-set controller just
take the equal portion of the power to ensure the equal load sharing and VAr sharing.
NOTE:
The power or PF control modes System Base load, System Base power factor, Import-Export, Import/Export
power factor can be used when the system is running in parallel operation to mains (LBI: MCB feedback is
active).
System Base load
Gen-set group is controlled on constant (or adjustable) power. The Baseload value can by changed by
setpoint or via analog input.
Important setpoints: ProcessControl: #SysLdCtrlPtM = BASELOAD; #SysBaseload; SysBaseLdMode.
System Base power factor
Gen-set group is controlled in mains parallel to keep a constant (or adjustable) power factor.
Important setpoints: ProcessControl: #SysPFCtrlPtM = BASEPF; #SysPwrFactor.
Import-Export
Gen-set group is controlled to keep constant (or adjustable) Import or Export value. The external controller
InteliMains NT must be connected on the CAN2 to control gen-set group kW I/E.
Important setpoints: ProcessControl: #SysLdCtrlPtM = LDSHARING.
Import/Export power factor
Gen-set group is controlled to keep constant (or adjustable) Import or Export power factor.
Important setpoints: ProcessControl: #SysLdCtrlPtM = VSHARING.The external InteliMains NT controller
must be connected on the CAN2 to control gen-set group PF I/E.
Local Baseload
Selected gen-set from island or mains parallel running group can be loaded to constant LocalBaseload
value. This bank with active function Local Baseload is taken out from load sharing and keeps the load of the
bank to be equal to the setpoint ProcessControl: LocalBaseload. The power of the bank is only reduced
when common group actual load is lower than this value, on the other hand is increased if the other banks
(gen-sets) running in loadsharing are not able to cover the load themselves. The gen-sets in the group will
try to match their LocalBaseloads (when more than one are put to local baseload) based on their controller
addresses, so the first limited would be the one with the highest CAN address.
Power management in system with Bank Controller
The Power management function in the system with Bank Controller decides how many banks and
subordinated gen-sets has to be running to cover the actual load and requested load reserve. On the top of it
the system ensures that the most efficient combination of the gen-sets (banks) to cover the load and
requested load reserve is running. The run hours equalization of particular gen-sets is also ensured.
The function is based on the load evaluation in order to provide enough of available running power. Since it
allows the system to start and stop gen-sets based on the load demand, it can vastly improve the system

IGS-NT-BC, SW Version 1.2.0, ©ComAp –January 2019
IGS-NT-BC-1.2.0 Reference Guide.PDF
20
fuel efficiency. In other words, an additional gen-set starts when the load of the system raises above certain
level. The additional gen-set stops, when the load of the system drops down below a certain level. The
process of determining gen-set start and stop is done in each controller; there is no "master slave" system.
Therefore, the system is very robust and resistant to failures of any unit in the system. Each of the controllers
can be switched off without influencing the whole system. Except the situation the respective gen-set is not
available for the power management.
The power management evaluates so called load reserve. The load reserve is calculated as difference
between actual load and nominal power of running gen-sets. The reserve is calculated as absolute value (in
kW / kVA) or relatively to the nominal power of gen-set(s) (in %). The setpoint Pwr management: #Pwr
mgmt mode is used to select the absolute or relative mode.
The automatic priority swapping function focuses on efficient run of gen-set in regards to running hours and
gen-set size.
CAUTION!
The function of the controller is designed to handle the maximum sum of nominal power at 32000kW
(3200.0kW, 320.00MW depending on the power format in the controller). If the sum of nominal power of all
gen-sets connected to the intercontroller CAN exceeds these values the power format needs to be changed
accordingly.
Example: There are 20 gen-sets each with 2000kW of nominal power. The sum of the nominal power is
40000kW. Therefore the power format in kW cannot be used because the sum exceeds 32767. Therefore
power format in MW needs to be chosen because the sum in MW is 40MW (it does not exceeds 320.00MW).
In the system with Bank Controller the power management is performed on two lovels, because the system
consists of several independent groups of gen-sets (CAN segments). The Bank Controller distributes the
data necessary for load sharing and VAr sharing among all the subordinated gen-set groups (CAN
segments) to ensure the equal distribution of the load. On the top of it it performs the inter bank
powermanagement. In the same time the second level of power management is performed between the
subordinated gen-sets inside the bank to provide the requested portion of power and requested load reserve
(not oll the gen-sets inside the bank are needed to be running simultaneously.
1. 1. Powermanagement inside the bank
The powermanagement inside the bank (the power management between the subordinated gen-sets)
respects the general principles of standard power management in standard MINT application, however it is
partly limited on this level, because some functionalities is performed on the level of inter bank
powermanagement and would be duplicated.
- The setpoints for setting of load reserves has been removed.
- Relative and kVA mode is not supported.
- Control Groups settings has been removed.
The Powermanagement inside the bank ensures:
- Starting and stopping of subordinated gen-sets according to the system load and the requested load
reserve.
- Priority Autoswap function inside the bank in “RUN HOURS EQU”, “LD DEMAND SWAP”,
“EFFICIENT” modes to ensure the most efficient combination of the gen-sets inside the bank to be
running and equalization of run hours among all the gensets inside the bank.
2. 1. Interbank powermanagement
The interbank power management works the same way like the standard MINT application. Starting and
stopping of particular banks is always based on priorities,actual systemload and actual set of load reserves.
- The powermanagement can run in Absolute or Relative mode (like describes in Figure: Power
management based on absolute load reserve and Figure: Power management based on relative
load reserve) selectable by the setpoint Pwr management: #Pwr mgmt mode.
- In the Absolute mode the power management can be evaluated based on the kW or kVA value
(setpoint Pwr management: #Pwr mgmt mode).
- The banks are started or stopped based on priorities (setpoint Pwr management: Priority) when
Pwr management: #PriorAutoSwap = DISABLED.
- The actual priority of each bank can be changed by the power management to equalize the run
hours of the banks Pwr management: #PriorAutoSwap = RUN HOURS EQU. (each bank counts
