We have 3 buses at our generating units. Bay3,4,5.

Bay 3&4 is connected with grid and Bay 5 is at radial load.

Now due to heavy load connected at bay 4 sometimes it trips on overcurrent . As per co-ordination with RCC we close the 52L of Bay 4. During this whole event we remain synchronised with national grid through Bay 3.

Now many times Bay 4 breaker did not close due to phase angle difference greater than 15 degrees.

We had a meeting RCC they said that it cannot be the issue to synchronise with us as you're already connected to grid through Bay 3.
