Problems solved by technology

[0004] 1) When the system load fluctuates greatly, the output power of the diesel generator set cannot quickly respond to the load change, resulting in that the output torque of the diesel generator cannot balance the electromagnetic torque of the generator, which in turn causes the speed fluctuation of the synchronous generator, and then Affect the stability of the generator set output voltage and frequency
[0005] 2) Since most of the diesel generators work off-grid, compared with the grid-connected power supply system, the power supply system of the diesel generator set has a smaller capacity and a larger equivalent output impedance. When there are a large number of reactive loads and When using power electronic devices, it will inevitably lead to the reduction of the efficiency of the generator set and the deterioration of the output voltage waveform
Therefore, the power quality of diesel generator sets is often lower than that of the public large power grid
