HYUNDAI HIMAP-BCG Generator Protection
HYUNDAI
New product
The HYUNDAI HIMAP-BCG is a sophisticated marine generator protection, automatic control and Power Management System (PMS) unit designed for generator bays and shipboard switchboards.
Unlike a simple protection relay, HIMAP-BCG combines several major functions inside one platform:
Generator Protection
Generator Automatic Control
Power Management
Automatic Synchronizing
Load Sharing
Breaker Control
Diesel Engine Control
Electrical Metering
Alarm / Event Monitoring
Programmable Logic and Communication
Hyundai marine switchgear literature describes HIMAP-BCG as a microprocessor-based intelligent measuring and protection device that performs automatic generator-control functions and provides multiple power-management features.

The photographed equipment shows two HIMAP-BCG panels from SM MARINE SERVICE™ stock.
The HIMAP family is a digital protection and control platform for low-, medium- and high-voltage electrical systems.
A HIMAP user manual describes three principal versions:
HIMAP-X – basic protection/control unit
HIMAP-BC – extended unit with LED indication, event recording and extension capability
HIMAP-BCG – further expanded with power management and diesel control.
That last distinction is important.
It is effectively a generator bay controller + protection relay + generator controller + PMS module.
Hyundai's marine documentation lists several automatic generator functions for HIMAP-BCG.
These include:
Automatic Synchronizing
Automatic Load Sharing
Load-Dependent Generator Start / Stop
Automatic Sequence Control after Alarm or Fault
Heavy / Big Consumer Blocking
Generator Priority Management
Diesel Engine Start / Stop Control
Remote Generator Control
This makes HIMAP-BCG particularly valuable in vessels operating several generators in parallel.
Before a generator can be connected to a live busbar, important electrical conditions must match.
Typically these include:
Voltage
Frequency
Phase relationship
HIMAP-BCG provides automatic synchronizing functionality so that the generator breaker can be controlled as part of the generator connection sequence.
The HIMAP family documentation lists ANSI 25/A Automatic Synchronizing among its supported capabilities.
This is one of the most commercially important search functions for HIMAP-BCG because buyers may search for:
Hyundai Generator Synchronizer
HIMAP Auto Synchronizer
Marine Automatic Synchronizing Unit
Generator Synchronizing Controller
Once two or more generators operate in parallel, load must be distributed correctly.
HIMAP-BCG supports load sharing, including symmetrical and asymmetrical load-control functions. Hyundai documentation explicitly lists automatic load sharing among its power-management functions.
In a multi-generator installation, the controller can participate in balancing generator load according to the configured PMS strategy.
HIMAP-BCG incorporates significant PMS functionality.
Technical literature describing HIMAP-BCG lists:
This is why the unit may be found under different buyer descriptions:
PMS Controller
Generator Controller
Generator Protection Relay
Power Management Module
Generator Bay Controller
All are valuable search terms, but HYUNDAI HIMAP-BCG remains the exact product identification.
One important PMS function is automatically determining when another generator should start or when an unnecessary generator may be stopped.
Historical HIMAP-BCG PMS setting documentation includes parameters such as:
Start next diesel
Generator priority
Remaining load
High current condition
Start / stop delays
Automatic mode
For example, when operating load rises beyond configured limits, the PMS may request another diesel generator to start and connect to the bus.
When demand later falls sufficiently, the system may permit a lower-priority generator to unload and stop according to the configured logic.
A vessel's electrical network must avoid complete blackout during generator overload.
HIMAP-BCG power-management functions include preferential trip / load shedding.
When available generating capacity becomes insufficient, selected non-essential consumers may be disconnected according to the configured PMS logic.
This reduces demand on the running generators and helps protect continuity of essential services.
Starting a large motor can cause a substantial temporary increase in electrical load.
HIMAP-BCG can participate in big-consumer start permission or blocking, using available generating capacity as part of the PMS logic. Hyundai documentation lists both heavy-consumer blocking and load calculation for large motor starting.
This functionality is especially useful for equipment such as:
Bow Thrusters
Large Pumps
Compressors
Cargo Pumps
Other High-Power Auxiliary Motors
depending on the individual vessel's PMS design.
HIMAP-BCG incorporates generator frequency-control functionality.
The regulator pages documented for HIMAP XG/BCG include dedicated regulation for:
Load Sharing
Frequency
Power Factor
Voltage
Generator speed/frequency correction commands can therefore form part of the overall generator-control strategy.
The same regulator architecture includes voltage-control functionality.
Depending on the generator installation and external AVR arrangement, HIMAP-BCG can participate in commanding voltage adjustment as part of generator synchronization, parallel operation and power-management functions.
Power-factor control is another supported function.
The HIMAP-BCG power-management documentation lists power-factor / cos φ control, including asymmetrical power-factor control.
This is especially important during parallel generator operation where active and reactive load distribution must be controlled appropriately.
HIMAP-BCG also includes diesel-engine control functions.
Hyundai marine literature lists:
Manual Start / Stop
Automatic Start / Stop
Remote Start / Stop
Pre-Lubrication Pump Control
Generator Start / Stop Monitoring
The unit therefore acts as part of both the electrical generator-control system and the diesel-generator operational sequence.
The wider HIMAP platform offers extensive protection functions according to ANSI device numbers.
Available HIMAP documentation covers protection suitable for generators, motors, transformers, feeders and electrical distribution systems.
Depending on installed hardware and configuration, generator-related protection can include functions such as:
Overcurrent
Earth / Ground Fault
Under / Overvoltage
Under / Overfrequency
Reverse / Directional Power
Negative Sequence / Unbalance
Differential Protection
Additional generator protection elements
The exact enabled protection functions must be checked from the installed HIMAP-BCG configuration rather than assumed from the front panel alone.
Hyundai connection drawings specifically include a configuration described as:
HIMAP-BC/-BCG: Generator for ship application with differential protection.
The drawings show separate CT arrangements, voltage inputs, protection outputs, current inputs/outputs and communication interfaces.
This demonstrates that HIMAP-BCG can be used in sophisticated generator-protection schemes where the installed configuration supports those functions.
The front panel provides visible I and O breaker controls.
HIMAP documentation describes breaker controls with display, control, blocking and interlocking capability. The platform can control multiple breakers depending on system configuration.
The built-in logic functionality also allows breaker interlocks and control sequences to be implemented.
HIMAP contains an integrated logic-builder / PLC capability.
The HIMAP manual describes a small integrated PLC for implementing individual interlocks and control functions.
This allows the unit to combine protection decisions with generator and switchboard automation logic without requiring every function to be implemented externally.
HIMAP supports communication with other controllers and central vessel systems.
Historical HIMAP marine documentation identifies:
RS-485
DNP 3.0
HD-BUS
Modbus remote monitoring
while connection drawings also show CAN and serial communication interfaces in specific configurations.
The exact protocol available on an individual HIMAP-BCG must be verified against its hardware/software revision.
One particularly interesting aspect of HIMAP-BCG is its distributed power-management philosophy.
Technical documentation describes a two-wire CAN bus linking HIMAP-BCG units associated with each generator panel. If one HIMAP-BCG fails, the remaining units can continue operating rather than depending entirely on a single central controller.
This distributed approach increases resilience in multi-generator marine power-management installations.
The front panel visibly provides separate digital displays for:
CURRENT – A / kA / %
VOLTAGE – V / kV / %
POWER – kW / MW / %
FREQ. / PF – Hz / cos φ
Hyundai marine literature also lists HIMAP metering including:
A, V, F, W, var, Wh, varh and PF.
This allows engineers to view key generator and network parameters from the same unit that performs protection and control.
Visible indicators include:
TRIP
ALARM
READY
COM.
SYS.CHECK
The F2 key is marked ALARMS, while F3 provides PROCESS information.
HIMAP documentation also describes:
Event Recording
Fault Recording
Fault Wave Recording
Sequence of Events (SOE)
Self-Diagnostics
Hyundai literature lists event recording up to 100 records and SOE resolution of 1 ms for the documented configuration.
These functions can significantly assist engineers during post-trip troubleshooting.
HYUNDAI HIMAP-BCG is particularly relevant to:
Main Generator Panels
Main Switchboards
High-Voltage Switchboards
Low-Voltage Main Switchboards
Diesel Generator Control Panels
Power Management Systems
Generator Synchronizing Panels
Parallel Generator Systems
Ship Electrical Distribution Systems
A published vessel machinery manual, for example, identifies a HiMAP-BCG Generator Protection and Power Management Unit as part of the vessel's main electrical-network documentation.
Check the control supply, terminal wiring, fuse/protection devices and installed power-supply requirements before suspecting internal controller failure.
Check internal diagnostics, communication condition, I/O configuration and event/alarm history.
A system-check indication should not automatically be assumed to mean the complete controller is defective.
Check:
AUTO mode selection
Generator availability / READY status
PMS generator priority
Remote start permissive
Diesel-engine alarm status
Start-blocking conditions
Load-dependent start settings
Verify:
Generator voltage
Bus voltage
Generator frequency
Bus frequency
Phase sequence
Synchronizing permissives
Breaker status feedback
Governor / AVR raise-lower control
Check synchronizing status, interlocks, breaker-ready signals, protection trips, CB feedback, logic conditions and closing circuit.
Do not bypass the synchronizing or interlock logic merely to force breaker closure.
Inspect:
Governor control interface
Active-power feedback
Generator ratings/configuration
Communication between HIMAP units
Load-sharing settings
Frequency regulator settings
Check AVR-related control, voltage measurement, PF regulation parameters and reactive-load control settings.
Check:
RS-485 / CAN wiring where applicable
Termination
Communication address
Protocol selection
Baud/settings
Cable shielding
Network health
Review the event and protection history before resetting repeatedly.
A protection trip is often a response to an actual electrical abnormality rather than a controller fault.
A HIMAP-BCG should not be replaced merely because another unit has the same blue front panel.
Before sourcing a replacement, verify:
Exact Model – HIMAP-BCG
Hardware Revision
Software / Firmware Revision
Generator Voltage and Current Configuration
CT / PT Ratios
Protection Settings
PMS Settings
Generator Number / Priority
Input / Output Mapping
Breaker Logic
Communication Protocol & Address
Governor and AVR Interfaces
Diesel Engine Start / Stop Logic
Where possible, settings from the existing working/failed unit should be backed up before replacement.
The HIMAP-BC and HIMAP-BCG belong to the same platform but should not automatically be treated as identical replacements.
The available user manual describes:
HIMAP-BC: expanded protection/control unit with LED indication, event recording and extension capability.
HIMAP-BCG: adds power management and diesel control to the extended controller platform.
Therefore, a vessel using BCG-specific PMS functions may require the correct BCG configuration rather than a generic HIMAP-BC.
These are also different functional products.
Hyundai marine literature identifies:
HIMAP-FI primarily for incoming/feeder protection.
HIMAP-BCG for generator automatic control and power-management functions.
