Requirements for Parallel Connection of Tongchai Diesel Generator Set

Jun. 02, 2023

The parallel connection of Tongchai diesel generator set must first meet the requirement of uniform distribution of power. The uniform distribution of power of Tongchai diesel generator set includes active power and reactive power. The so-called uniform distribution means that the active and reactive power of each diesel generator set shall be proportional to its rated power. China has clear requirements for the distribution of diesel generator sets connected in parallel. When the load of Tongchai diesel generator set changes within 20% - 100% of the total rated power, Tongchai diesel generator set shall be able to operate stably.

If the active power distribution of the parallel connected diesel generator set is seriously unbalanced, when the total load power of the diesel generator set is large, one diesel generator set is usually full load or overload, while the other diesel generator set is still under light load, so the diesel generator set cannot fully use and play the efficiency of the whole power station. Overload of Tongchai diesel generator set will not only harm the diesel engine or generator, but also cause the action of Tongchai diesel generator set protection device, affecting the operation of the whole power station of Tongchai diesel generator set.

When the total load power of Tongchai diesel generator set is very small, the imbalance of active power will often cause the active circulation between Tongchai diesel generator sets, making some Tongchai diesel generator sets enter the motor state, which is also not allowed by Tongchai diesel generator sets. When Tongchai diesel generator set has reverse power protection, reverse power phenomenon will cause reverse power tripping and cause fault. For diesel power plants with frequent and significant load changes, the above situations should be given more attention. The uniform distribution of power between Tongchai diesel generator sets in parallel operation is not only a problem of economic operation of Tongchai diesel generator sets, but also an important factor to ensure the power supply reliability of the whole Tongchai diesel generator set plant.
