6 FAQs about [Gcb energy storage motor failure analysis]

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.

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.

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.

Can GCB failure protection be improved in large power plants?

The results of this study can provide effective technical support for the improvement of GCB failure protection in various large power plants with different PT configuration schemes.

What happens if GCB fails?

In addition, the switching of GCB is controlled by the mechanical connecting rods, and there have been open-phase accidents caused by connecting rods breaking . 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.
