Analyze the cause of the voltage instability of the diesel generator set

June 01, 2022
Whether the voltage of the diesel generator set is stable or not is directly related to the power of the diesel generator set, especially for some manufacturers who need to use the diesel generator set to make economic benefits, if the voltage of the diesel generator set is unstable, the economic loss caused is Very huge, this article will give you a detailed analysis of the reasons for the voltage instability during the operation of diesel generator sets.
       Whether the voltage of the diesel generator set is stable or not is directly related to the power of the diesel generator set, especially for some manufacturers who need to use the diesel generator set to make economic benefits, if the voltage of the diesel generator set is unstable, the economic loss caused is Very huge, this article will give you a detailed analysis of the reasons for the voltage instability during the operation of the diesel generator set.
 
       1. The excitation voltage of the diesel generator set is unstable or the carbon brush is in poor contact. Specifically, the excitation winding and excitation power components, including rectification, can be checked.
       2. Diodes, thyristors and other resistance-capacitance components, and adjustable potentiometers will often have poor contact and lead to voltage instability. Users should pay attention to maintenance in daily operations.
       3. The load on the diesel generator set is too large, and the large electrical appliances on the load are frequently started, causing the voltage to fluctuate greatly, causing the voltage to be unstable.
       4. The damage of the voltage regulator components causes the generator set voltage to be unstable.
       5. The poor circulation of the fuel pipe of the generator set causes unstable engine speed and voltage instability.
       6. The unstable load of the equipment will also cause the voltage instability of the diesel generator set.
 
       In view of the phenomenon of unstable voltage of diesel generator sets, it is recommended that users must have special personnel to guard and maintain regular maintenance when using diesel generator sets to ensure that the above phenomenon does not occur, and to ensure that all parts of the generator set are normal and in good condition. Ensure that the diesel generator set is running at a normal and stable voltage. When the voltage of the diesel generator set is abnormal, do not start it without authorization, and contact the professional staff of the generator manufacturer to conduct operation inspection and troubleshoot in time.
