1. Load imbalance: When the load is unbalanced, the power output by the generator will be consumed by part of the load, resulting in a decrease in the speed of the generator, which in turn leads to a decrease in frequency.
2. Too little fuel: When the fuel is insufficient, the generator will automatically slow down to protect the engine, resulting in a decrease in frequency and speed.
3. Fault: If the engine fails or the generator fails internally, the frequency and speed will decrease.
4. Fault in the parallel control system: Fault in the parallel control system may cause uneven parallel power distribution, resulting in a decrease in frequency and speed.
1. Balanced load: The power should be balanced between the loads to ensure that the power output by the generator can be fully consumed, thereby increasing the frequency and speed.
2. Increase fuel supply: Increasing the fuel supply can increase the engine speed, thereby increasing the frequency and speed.
3. Timely maintenance: In case of a fault, the faulty parts should be repaired or replaced in time to restore the normal frequency and speed.
4. Parallel control system maintenance: Regularly maintain and inspect the parallel control system to ensure its normal operation, so as to ensure balanced parallel power distribution and avoid frequency and speed drops.
