Analysis of Unstable Rotary Speed of Marine Generating Set

The unstable rotary speed of diesel generator set will cause bad combustion of diesel,affect other equipments' normal running,even shut down the power.The fuel supply unit,electronic control unit and electromagnetic unit,which caused the unstable rotary speed of generator,were checked and analyzed to eliminate the fault.With the wide utilization of electrical control in marine,the manager should strengthen electrical control training.The detail should be paid more attention to during faults diagnosis.The operation should be done by criterion to avoided the malfunction.
