Voltage Specifications and Troubleshooting as Standby Power Supply

For many industries, diesel generator sets are the primary choice as standby power sources due to their high power output, stable voltage, fuel economy, high thermal efficiency, relatively flat fuel consumption rate curve under varying operating conditions (economical even at low loads), and reliable, durable operation.

Voltage Level Requirements for Diesel Generator Sets as Standby Power Supply

① When the power supply radius is not greater than 400m, low-voltage diesel generator sets should be used.

② When the power supply radius is greater than 400m, medium-voltage diesel generator sets should be used.

③ The line voltage drop should not exceed 5% of the supply voltage.

Summary: Low voltage for short distance (≤400m), medium voltage for long distance (>400m), voltage drop ≤5%.

Solutions for Low Voltage of Diesel Generator Sets as Standby Power Supply

1.Excessive resistance in the excitation circuit.

Processing: Reduce the resistance of the magnetic field rheostat to increase the excitation current.

2.The prime mover speed is too low.

Processing: Adjust the prime mover speed to the rated value.

3.The exciter brushes are not in the neutral position or the spring pressure is too low.

Processing: Adjust the brushes to the correct position, replace the brushes, and adjust the spring pressure.

4.Some rectifier diodes are broken down.

Processing: Inspect and replace the broken-down diodes.

5.There is a short circuit or ground fault in the stator winding or excitation winding.

Processing: Inspect for faults and eliminate them.

6. The brush contact area is too small, insufficient pressure, or poor contact.

Processing: If caused by an uneven commutator surface, polish the commutator surface with sandpaper at low speed, or adjust the spring pressure.
