How to Deal with The Abnormality of The Silent Diesel Generator Set?

Dec. 13, 2021

What should you do if you encounter an abnormality in a silent diesel generator set. The decibel of a silent diesel generator set is very low. What should we do if there is an abnormality during work? The following generator set manufacturers will introduce to you. Silent Diesel The phenomenon of generator current imbalance: the stator three-phase current indications are not equal to each other, the three-phase current difference is large, and the negative sequence current indication value also increases. When the unbalance exceeds the limit and the regular working time is exceeded, the negative sequence signal device sends a "generator asymmetric overload" signal, which constitutes the vibration and heat of the rotor.

The reason for the current imbalance of the quiet diesel generator set is that one phase of the generator and its circuit is disconnected or the circuit breaker is not in contact with one phase, and a certain transmission line is not working in full phase. The single-phase load of the system is too large: If there is a large-capacity single-phase load, the stator ammeter or meter loop will also cause the stator three-phase ammeter to indicate asymmetrical. The treatment method for the current imbalance of the silent diesel generator set: When the generator three-phase current imbalance exceeds the limit, if it is determined that it is not caused by the meter circuit fault, immediately reduce the load of the diesel generator set to reduce the unbalanced current to the allowable value Following, and then report to the system scheduling. After the three-phase current is balanced, the diesel generator set load is added according to the dispatching instruction.

The difference between the three-phase current of the turbine generator shall not exceed 20% of the rated current, and the current of any one phase shall not exceed its rated value. The negative sequence current promised by the turbine generator shall not be greater than 12% of the rated current.
