ENMAKSAN POWER / Parallel generation & power management
Synchronization Systems.
Multiple generators.
One coordinated system.
Bring generation, switching and control together. Explore generator synchronisation and load-sharing solutions built around your electrical network, operating modes and continuity requirements.

More than connecting
generators together.
Parallel generation brings capacity, control and protection into one engineering plan.
ENMAKSAN POWER provides generator synchronisation and power management solutions for industrial, commercial and infrastructure applications. Compatible generating units can operate on a common bus and share demand through an agreed control strategy.
The design starts with the single-line diagram and the required operating modes. Generator-to-generator operation, utility paralleling and automatic transfer each introduce different switching, protection and approval requirements.

Match. Connect.
Share the load.
A simplified overview of connecting a generator to an energised bus. Actual sequences and acceptance conditions are project-specific.
The selected generator starts. Compatible controls bring voltage and frequency toward the bus conditions and verify phase relationships.
Synchronism checks, breaker feedback and interlocks confirm the permitted conditions before the generator breaker is commanded to close.
Controls coordinate active and reactive loading while monitoring the system and responding to demand changes or protective events.
Choose the mode.
Define the control strategy.
Generator to generator
Compatible units supply a common bus. The control strategy defines load sharing, capacity management and the response to a unit becoming unavailable.
Generator to grid
Generators operate in parallel with the utility under an approved connection arrangement, with specified protection and import/export limits.
Automatic or supervised
Define automatic, semi-automatic or manual operating responsibilities while preserving the required checks, interlocks and protection.
Power management
around real demand.
Potential applications to assess against the load profile and required continuity of service.
Industrial facilities
Coordinate multiple generating units around production demand, large load steps and essential process utilities.
Data centres
Review generator capacity and restoration sequences alongside UPS systems and the defined redundancy strategy.
Hospitals & campuses
Coordinate generating capacity with critical distribution and the required transfer times for each load group.
Commercial campuses
Plan central generation for multiple buildings with load priorities and coordinated switching.
Isolated networks
Assess parallel generation where no reliable utility connection exists and loads vary throughout the operating day.
Approved grid-parallel projects
Evaluate peak management or controlled transfer where technically appropriate and permitted by the network operator.
Define the logic.
Coordinate the interfaces.
A clear specification aligns generators, switchgear, protection and supervisory controls before implementation.
Network architecture & operating modes
Define the single-line diagram, bus arrangement, generator ratings and required operating modes. Identify island operation, generator-to-generator paralleling and any utility-parallel operation separately. Specify the intended response to utility loss, generator faults and restoration of the normal supply.
Synchronisation & breaker control
The incoming generator must meet the required voltage, frequency and phase conditions before connection to an energised bus. Phase sequence, synchronism checking, breaker status feedback and electrical interlocks form part of the coordinated design. Dead-bus energisation requires a separate controlled sequence.
Active & reactive load sharing
Active power sharing is coordinated through compatible engine governing controls; reactive power sharing depends on compatible excitation and voltage regulation. Define proportional loading, power-factor or reactive-power control requirements for each operating mode. Different unit sizes require an agreed sharing strategy.
Protection & fault coordination
Review fault levels, breaker duties, instrument transformers, earthing and the protection philosophy. Evaluate generator and network protection against the proposed topology. Settings, selectivity and utility interface protection require project-specific studies and commissioning by the responsible specialists.
Capacity management & load priorities
Specify which loads are essential, which can be shed and the sequence for restoring them. Define the reserve capacity, start/stop strategy and minimum operating conditions. Redundancy must account for the available generating capacity, common equipment and the loads that must remain supplied.
Controller compatibility & communications
Confirm interfaces between generator controllers, governors, automatic voltage regulators, switchgear and the supervisory system. Agree communication protocols, alarm lists, status signals and operator access. Existing equipment compatibility must be checked before promising a retrofit or mixed-brand installation.
Testing, commissioning & documentation
Agree factory and site acceptance tests covering synchronisation, load sharing, breaker interlocks, load shedding and responses to faults or communication loss. Define utility witness requirements where applicable. Request approved diagrams, control descriptions, settings records, test results and operator documentation.

What is a generator synchronization system?
It is a coordinated control and switching arrangement that enables compatible generators to connect in parallel. Before connection to an energised bus, it checks the required electrical conditions. After connection, the system manages operation and load sharing according to the agreed control strategy.
Can generators with different power ratings run together?
They may be able to, provided their electrical characteristics, controls and protection are compatible. Load sharing should reflect the rated capacity and operating limits of each unit. Compatibility requires an engineering review; different ratings alone do not establish suitability.
Can generators operate in parallel with the utility?
Yes, where the installation is designed for that operating mode and the utility approves the connection. Interface protection, metering, switching and import or export limits must meet the applicable requirements. Grid paralleling is not automatically included in every synchronisation system.
Does synchronization guarantee uninterrupted power?
No. Transfer continuity depends on the network topology, controls, available generation and the type of disturbance. Synchronisation alone does not replace a UPS. Define allowable interruption times and any ride-through requirements for critical loads.
Can an existing generator installation be upgraded?
A retrofit may be possible after reviewing the generators, controllers, governors, voltage regulators, breakers and protection. Existing equipment condition, communication interfaces and required operating modes determine the practical scope.
What information is needed for a proposal?
Provide the single-line diagram, generator ratings, controller details, voltage, frequency, load profile and required operating modes. Include utility connection requirements, redundancy objectives, load priorities and the proposed installation location.
