Loss of Synchronism in two synchronous generators
Loss of synchronism refers to a situation where two synchronous generators, which are interconnected are no longer operating at the same frequency. This can result in the following:
Wild fluctuation in current and voltage:
When two synchronous generators are connected, they operate in parallel and share the load. However, if the frequency of one of the generators changes, the load sharing will be affected. As a result, one generator will try to supply more current than the other, causing a fluctuation in current and voltage.
Generator tripping:
If the loss of synchronism is severe, the generators may trip, causing a total blackout. This occurs when the difference between the frequencies of the two generators is large enough to cause a complete loss of synchronization.
Mechanical damage:
Loss of synchronism can also cause mechanical damage to the generators. When the generators are no longer synchronized, the rotor of one generator will try to catch up with the other. This can cause the rotor to overheat and eventually fail.
Conclusion:
In conclusion, loss of synchronism in two synchronous generators can result in wild fluctuations in current and voltage, generator tripping, and mechanical damage. It is, therefore, essential to ensure that the generators are properly synchronized to prevent these issues.
