Generator synchronization is an essential part of safe and reliable marine electrical operation. When two or more generators operate in parallel, the incoming generator must be correctly matched with the live busbar before its circuit breaker is closed. Our Generator Synchronization Services in Lome are designed for vessels requiring synchronization troubleshooting, commissioning, adjustment, testing and repair at Lome Port.

Synchronization involves several electrical parameters, including voltage, frequency, phase sequence and phase relationship. Incorrect synchronization can create significant electrical and mechanical transients, potentially causing breaker trips, generator faults or instability within the ship's electrical network.

MARINE GENERATOR SYNCHRONIZATION TESTING

Our technicians can inspect the synchronization system and determine why a generator is unable to connect correctly to the main switchboard.

The inspection may include generator voltage and frequency measurements, phase sequence verification, synchroscope operation, synchronizing lamps, breaker control circuits and relevant protection functions. Where an automatic synchronizer or Power Management System is installed, the control signals and operating sequence can also be checked.

This allows synchronization problems to be separated from faults originating in the generator, AVR, governor, switchboard or circuit breaker.

VOLTAGE AND FREQUENCY MATCHING

Before paralleling a generator, its electrical output must be brought into the required relationship with the running busbar. Generator speed and frequency are normally controlled through the prime mover governor, while excitation and voltage are controlled through the AVR.

Incorrect frequency adjustment can cause unstable synchronization or undesirable load transfer after breaker closure. Similarly, incorrect voltage or excitation settings can affect reactive power distribution between generators.

Our ship generator synchronization service in Lome includes checking these parameters and identifying abnormal regulation or control responses.

PHASE SEQUENCE AND SYNCHROSCOPE CHECKS

Correct phase sequence is fundamental when connecting a three-phase generator to an energized busbar. The incoming generator must have the appropriate phase rotation and phase relationship before the breaker is closed.

Synchroscopes and synchronization lamps can be inspected where fitted. Automatic synchronizing equipment can also be tested to verify that the system receives the correct voltage, frequency and phase information before issuing the breaker-closing command.

If synchronization is unsuccessful, wiring, sensing circuits, instrument transformers, control relays and synchronizer settings may require further investigation.

GENERATOR PARALLELING AND LOAD SHARING

Once generators are synchronized, correct load sharing becomes important for stable parallel operation. Active power distribution is generally associated with governor control, while excitation and AVR settings influence reactive power distribution.

Uneven load sharing, excessive circulating current, unstable kW/kVAr distribution or reverse-power trips may indicate problems within the generator controls or synchronization system.

We can investigate these conditions and support the adjustment and testing of the relevant control equipment.

SYNCHRONIZATION SERVICES AT LOME PORT

Our Generator Synchronization Services in Lome are available for auxiliary generators, emergency power systems and marine alternators requiring synchronization inspection or troubleshooting.

For a ship calling at Lome, service can be coordinated with planned electrical maintenance or an urgent generator problem. Whether the issue involves manual synchronization, automatic synchronizer failure, incorrect phase sequence, unstable frequency, breaker closing problems or poor load sharing, systematic testing can identify the source of the fault.

Following testing and adjustment, the synchronization system can be functionally checked to confirm reliable generator paralleling and stable operation of the vessel's electrical distribution system.
