Causes of Silent Diesel Generator Sets Trip

Mar. 09, 2022

There will be a tripping phenomenon during the use of the silent diesel generator set, so do you know what are the reasons for the tripping of the silent diesel generator set? In this article, the Starlight Power Generation Equipment will be introduced to you:

1. Check whether the indicator device of the silent diesel generator set has obvious fault symbols. Sometimes the excitation should be cut off immediately. If there is no abnormal symbol, the duty personnel should adjust the generator voltage and frequency within the normal range when the machine and furnace are in good condition. , check whether the high-voltage power supply of the unit is tripped, and whether the starting transformers are connected to each other. Is the power supply normal.

2. According to the accident phenomenon and relay protection action, determine the nature and scope of the fault, and conduct a detailed external inspection of the transformer group and related equipment of the silent diesel generator set to determine whether there are external fault characteristics.

3. If the over-current protection of the silent diesel generator set is caused by the busbar differential, or the over-current protection of the silent diesel generator set is caused by the fault of the substation, check that the external of the generator is normal. After the fault is isolated, contact the network to adjust and connect to the power grid.

4. Before the trip, such as strong excitation, there is a current impact, which reflects the main protection (differential, heavy gas, etc.) of the internal fault of the generator-transformer group of the silent diesel generator set. The power grid is running normally, and it should be dealt with at this time.

5. If there is no strong excitation, there is no inrush current before the trip, the power grid is running normally, the engine and furnace are normal, the water and hydrogen oil systems of the generator and main transformer of the silent diesel generator set are normal, such as checking the silent diesel generator set and its circuit ; Check the action protection, such as all normal generators can start with zero voltage. If all goes well during the boost process, the generator can be connected to the grid and continue to find out why.
