FAQs
1. What is generator synchronisation?
Generator synchronisation is the process of matching the voltage, frequency, phase sequence, and phase angle of a generator with an energized electrical system before connecting them together.
2. Why is synchronisation important in power generation?
Synchronisation ensures generators can connect safely to a common busbar or power network. Correct synchronisation helps prevent electrical disturbances, equipment damage, and unstable operation.
3. What are the main conditions for synchronising generators?
The main conditions are equal voltage, matching frequency, identical phase sequence, and a suitable phase angle difference. These conditions help ensure safe generator connection.
4. What is load sharing between generators?
Load sharing is the distribution of electrical demand among two or more generators operating in parallel. It helps balance generator loading and improve overall operating efficiency.
5. What is the difference between active and reactive load sharing?
Active power sharing relates to the real electrical power supplied by generators and is mainly controlled through their governors. Reactive power sharing concerns voltage support and is influenced by excitation and AVR systems.
6. What equipment is used for generator synchronisation?
Common equipment includes synchronoscopes, synchronising lamps, automatic synchronising relays, voltage meters, frequency meters, and generator control panels.
7. What happens if generators are incorrectly synchronised?
Incorrect synchronisation can cause high circulating currents, mechanical stress, electrical disturbances, and damage to generator components. Proper synchronising checks are essential before closing the circuit breaker.
8. Who should attend this training course?
The course is suitable for electrical engineers, power plant operators, generator technicians, maintenance supervisors, and professionals responsible for generator control and parallel operation.
9. What are common generator load sharing problems?
Common problems include unequal power distribution, unstable frequency, reactive power imbalance, circulating currents, and incorrect governor or AVR settings.
10. What skills will participants gain from this course?
Participants will develop skills in synchronisation procedures, parallel generator operation, load distribution, synchronising equipment operation, fault diagnosis, and generator control.
