    Causes of voltage and frequency fluctuations in diesel generator sets

    Compared with the city power, even the diesel generators with high output power are insignificant. Due to its limited output power capacity, it has adaptive requirements for the input power of the load, the higher harmonic components of the input current, and the input power factor. Otherwise, the electrical equipment and the generator set will be in poor working condition.


    When the engine generates power with a generator, the three-phase windings in the stator output voltage and current to the load in order of 120 ° electrical angle. In general, when electrical equipment with an input power equivalent to about 60% of the output power of a diesel generator set is connected to the output end of the generator set, it will cause obvious and even strong fluctuations in frequency and voltage.


    This is because the load needs to input a large current at the moment, which causes the current in the three-phase winding to increase sharply. The strong electromagnetic force generated by this current attracts the rotor of the generator, causing its speed to slow down and the frequency and voltage to drop instantly. It can be seen that how much current needs to be input when the electrical equipment is connected is the key factor for whether it and the generator set can work normally.
