Synchronization / Advantages of Synchronization System

More Generators, More Advantages

 Bulit by synchronizing a number of generators having small ratings, this system provides certain advantages in comparison to a single generator having a higher rating. Said advantages are:

– Lower costs
– Comparative cost advantage
– Lower initial investment budget
– Flexible use
– Reliable system
– Easy technical and maintenance services
– Easy delivery and supplement of spare parts

Synchronization Control Panels

 THE POWERHOUSE  Generators is able to provide the following solutions for various synchronization applications.

– Synchronous operation of multiple generator sets with each other
– Synchronous operation of a single generator set with network
– Synchronous operation of multiple generator sets with network
– Synchronous operation of multiple generator sets with multiple networks

By what mechanism can generator sets be synchronised (run in parallel)?

In order to parallel a.c. generators, certain conditions must be met. All systems must:
Have the same voltage.
Have the same phase rotation.
Have the same frequency.
Have the same angular phase relationship.
Share the load with respect to their ratings.
Normally, one generating system is used to establish the common bus, and the oncoming generator is then synchronised to that bus by changing the speed of the prime mover driving the oncoming generator.

Manual Synchronisation

Manually synchronised systems rely on monitoring equipment to indicate to the operator when the two systems are synchronised closely enough for safe paralleling. This equipment may include indicating lights, a synchroscope, a synch-check relay, or a paralleling phase switch.

These manual systems, where the accuracy of synchronization depends on the hands and skill of the operator, are giving way to automatic synchronising systems.

Automatic Synchronisation

A modern synchronizer compares the frequency and phase of the two voltages, and sends a correction signal to the summing point of the governor controlling the prime mover of the oncoming generator. When the outputs of the two systems are matched in frequency and phase, the synchronizer issues a breaker-closing signal to the tie-breaker, paralleling the two systems.

These synchronizers may include voltage-matching circuits which send raise and lower signals to the voltage regulator of the oncoming generator. If the voltage of the oncoming generator does not match the bus within set limits, the synchronizer will not allow a circuit breaker closure.
