2.2 Appl ications with GCB cont rol and no MCB

Typical applications: MRS (SPM): Manual or remote start/stop of a single engine

Typical applications: Multiple sets running in island-parallel

Typical applications: CHP with no island operation (no backup)

2.3 Appl ications with GCB control with external MCB cont rol

Typical applications: AMF with multiple sets running in island-parallel. MCB controlled by a simple mains protection relay

or InteliMains

AMF with no break return (multiple sets). MCB controlled by InteliMains-NT. Parallel to Mains with AMF for multiple sets (CHP) MCB controlled by InteliMains-NT.

Typical applications: CHP with external MCB control. Normally the load is higher than gen-set capacity and non-

preferential load must be switched off before gen-set can be switched to island operation.

2.4 Generic applications

Controller performs individual steps like: Gen-set start GCB dead bus closing Synchronizing

Load control mode Reverse synchronizing Gen-set stop

Steps are driven by commands from an external device, e.g. PLC. This device is responsible for allsequencing (steps order).

Typical applications: Complex systems with several buses where PLC controls each step of the gen-set. Complex CHP applications controlled from a central PLC

Description

The IM-NT (MCB) controller opens MCB after the mains fails or after the gen-sets are runningaccording to setpointAMF sett ings:MCB opens on.

The IM-NT controller closes binary output Sys start/stop which is connected to Sys start/stop inputsof the gen-set controllers in the corresponding group if:- If IM-NT (MCB) binary input Rem start/stop gets active (AUT mode only).- If AMF condition is sensed in IM-NT (MCB) and the gen-set group should be started as stand-by

power source (AUT mode only).- If PeakShaving function senses that it is suitable to start the gen-set group in order to lower

the mains import (AUT mode only).- If Start button is pressed on IM-NT front panel or remotely (MAN mode only). The signal can bedeactivated by pressing the Stop button. If the controller is switched from AUT to MAN mode, theinternal status of the flip-flop circuit created by Start-Stop buttons is set to follow the previous state inAUT mode. E.g. if the gen-set group has run in an AMF situation in AUT mode, switching to MAN willnot stop it (=Sys start/stop output stays active).


When the mains returns, IM-NT (MCB) synchronizes gen-sets to the mains with limitations given bysetpoints ProcessControl:ParallelEnable and Synchro enable (see Table on p.9 in IM-NT-MCB-MGCB-X.X.pdf).

The gen-set controllers know whether they are connected to the Mains from binary input MCBfeedback that can be configured on binary output InMainsParal (using VPIO for instance). Thisbinary output is distributed over the CAN bus and indicates which MCBs are closed and connectedto the Mains. Based on this information the gen-set controllers are controlled by one or another IM-NT (MCB) controller.

Description with MGCB The system with this topology has to be separated into 4 logical groups by 3 IM-NT (BTB)

controllers. It is not possible to use IM-NT MGCB application for this purpose. The IM-NT (MCB) controller opens MCB after the mains fails or after the gen-sets are running

according to setpointAMF sett ings:MCB opens on. IM-NT (BTB) controller closes automatically BTB/MGCB if

- bus voltages are within the limits (Sync ctrl:Phase window, Voltage window)- there is voltage on one of the buses and closing to dead bus is enabled by

ProcessControl:DeadBusClosing- binary inputBTB disable is not closed- it is enabled by setting ofProcessControl:Synchro enable, Mains coupling setpoints

After binary input Sys start/stop closes the gen-sets are starting with a delay SysAMFstrtDel. It issimilar to setpoint EmergStart del in SPtM application. The first set with a correct voltage andfrequency closes the GCB to the dead bus, others are synchronized.

The gen-set controllers know whether they are connected to the Mains from binary input MCBfeedback that can be configured on binary output InMainsParal (using VPIO for instance). Thisbinary output is distributed over the CAN bus and indicates which BTBs are closed and so whichlogical groups are interconnected and connected to the Mains. Based on this information the gen-set

controllers are controlled by one or another IM-NT (MCB) controller.

Hint:It is possible to use virtual shared inputs/outputs to connect for example Sys start/stop output from IM-NT tocorresponding binary input of all controllers instead of hardwiring it. See chapter Shared virtual I/O periphery.For BTB controllers the BI BTB Feedback should be configured as Group link input as well.

Description


The IM-NT controller closes binary output Sys start/stop which is connected to Sys start/stop inputsof the gen-set controllers in the corresponding group if:- If IM-NT (MCB) binary input Rem start/stop gets active (AUT mode only).

- If Start button is pressed on IM-NT front panel or remotely (MAN mode only). The signal can bedeactivated by pressing the Stop button. If the controller is switched from AUT to MAN mode, theinternal status of the flip-flop circuit created by Start-Stop buttons is set to follow the previous state in

AUT mode. E.g. if the gen-set group has run in an AMF situation in AUT mode, switching to MAN willnot stop it (=Sys start/stop output stays active).- If IM-NT binary input Rem start/stop gets active (AUT mode only). Before the output Sysstart/stop is activated, the MGCB close command is issued (ifProcessControl:MGCBparalClose =YES).- If AMF condition is sensed in IM-NT and the gen-set group should be started as stand-by powersource (AUT mode only). MGCB is not closed before the GCBs but only after a reasonable amountof gen-sets have synchronized to the bus (load reserve achived).- If PeakShaving function senses that it is suitable to start the gen-set group in order to lower themains import (AUT mode only). Before the output Sys start/stop is activated, the MGCB closecommand is issued (ifProcessControl:MGCBparalClose = YES).



The gen-set controllers know whether they are connected to the Mains from binary input MCBfeedback that can be configured on binary output InMainsParal (using VPIO for instance). Thisbinary output is distributed over the CAN bus and indicates which BTBs are closed and so which

logical groups are interconnected and connected to the Mains. Based on this information the gen-setcontrollers are controlled by one or another IM-NT (MCB) controller.

Description

The system with this topology has to be separated into 4 logical groups by 3 IM-NT (BTB)controllers. It is not possible to use IM-NT MGCB application for this purpose.


IM-NT (BTB) controller closes automatically BTB/MGCB if- bus voltages are within the limits (Sync ctrl:Phase window, Voltage window)

- there is voltage on one of the buses and closing to dead bus is enabled byProcessControl:DeadBusClosing

- binary inputBTB disable is not closed- it is enabled by setting ofProcessControl:Synchro enable, Mains coupling setpoints




Hint:It is possible to use virtual shared inputs/outputs to connect for example Sys start/stop output from IM-NT tocorresponding binary input of all controllers instead of hardwiring it. See chapter Shared virtual I/O periphery.For BTB controllers the BI BTB Feedback should be configured as Group link input as well.
