6 FAQs about [Gcb energy storage motor failure analysis]

How to detect GCB failure?

For the detection of GCB failure faults, there are newly built power plants whose generator has installed PTs on both sides of the GCB (at the generator terminal and the low voltage side of the step-up transformer). However, for some power plants, only one PT is installed at the generator terminal.

What is a generator circuit breaker (GCB) failure protection?

Safe and reliable generator circuit breaker (GCB) failure protection can ensure effective isolation between generator and system under different fault conditions to avoid generator damage.

What happens if GCB fails?

When GCB fails, the GCB failure protection should be applied to switch other circuit breakers associated with GCB to ensure the generator and the system can be effectively isolated. The existing circuit breaker failure protection is formed of current quantities.

How does GCB failure protection work?

For the generator only equipped with terminal PT, the proposed GCB failure protection criterions based on the voltage variation are simulated to identify the GCB three-phase rejection fault under different loads. At 2.0s, a single-phase ground fault occurs, and at 3.0s, the GCB failure protection operates and the generator starts to de-excite.

What happens if GCB fails in a generator?

At 2.0s, a single-phase ground fault occurs, and at 3.0s, the GCB failure protection operates and the generator starts to de-excite. Simulation verification is carried out under light load and heavy load condition, respectively. The generator terminal voltage waveforms are shown in Fig. 9 under different conditions.

What is GCB failure protection criterion?

On this basis, a GCB failure protection criterion based on the voltage phasor difference is proposed for the generators equipped with PTs at the two sides of GCB. After a generator fault occurs, in the process of de-excitation, the terminal voltage drops quickly except GCB three-phase rejection because of the voltage support from the system side.
