After the diesel generator generates electricity, the faults of unstable voltage and frequency are usually caused by unstable excitation current or low residual excitation voltage of the exciter. When the excitation current of the diesel power generator is unstable or the residual magnetic voltage of the exciter is low, the AC voltage produced by the cutting force line of the stator will be unstable and the frequency will fluctuate. What shall I do? Starlight manufacturer answers for you. The reason for unstable frequency after starting diesel generator: 1.Air enters the fuel line of the fuel supply system, which makes the speed of the diesel engine unstable. 2.Blockage in oil pipeline. 3.The uneven fuel supply of high-pressure oil pumps leads to different deflagration power of diesel fuel in combustion chamber. 4.Poor atomization of fuel injector in cylinder results in different deflagration power of diesel fuel in combustion chamber. 5.Damage of stable regulating comp...
