Looks like your power plant is : Gardabani Combined Cycle Power Plant Project And Calik energy is the EPC , oh ok Chinese are EPC for the second phase of this project...Tianchen Engineering Corporation (TCC) So better to contact them for gettting these informations ... Controls Guy25.

As it is GE frame 6FA i suggest you to contact GE belfort (GEEPE ), otherwise EPC contractor ( you said that chinese built the plant is that HARBIN power ?? ) for giving you the Operations & Maintenance manuals and a correct & good training . We do not know about contract service agreement that...

Could you at least try to respond to my questions on my last post . We trying to support you but you dont cooperate so if no answers i will be off this thread.

You may have a read on this thread: https://control.com/forums/threads/generator-rotor-shaft-vibration-with-increasing-of-excitation-current.41359/ It is written in the title " when increasing excitation current" but it looks like this phenomena occurs as soon as 52G close ( synchronization)...

Ok I know that during standstill there is no permissive for synchronization, anyway there should be a method /operation to do for simulating synchronization at standstill, Maintenance crew at power plant do that during outages, for 52G functionnality tests. If vibration peaks are not...

Coud you try to respond to this post .. Did you ever perform 52 closing/opening command when unit at standstill??? If yes do the isssue is still there? I do not know if you swapped sensors and get same results?? Yes, the vibro sensor was changed and the issue persisted By now it would be...

Mutahir, As per the informations that you provided, we can think about a misalignement ...and in other hand can be another source of vibrations... & you stated that soft foot can be eliminated . Did you ever perform a realignement and checked results ? Do you know critical speed of the motor...

Do you observing continuous "vibrations"peaks", or intermittent or just on the time period for 52G closing when this phenomen occur?? It can ben a noise signal, as you stated that turbine and load gear & generator have no vibrations constated ?? Controls Guy25.

Did you ever perform 52 closing/opening command when unit at standstill??? If yes do the isssue is still there? I do not know if you swapped sensors and get same results?? By now it would be difficult to give more guidance as we are not present at site. Let see if somebody on the forum had...

Thanks for sharing the screenshots. Thats quite impressive ! Did you ever perform noise test/measuring around or close to the mentionned devices?? It could be some CEM issue... According to your statements 52Gclosing command or 52G closed feedback... can make such disturbances? Can you tell...

Hello Team, Cheede, Is there any work have been done on 52G ,,,? Or other auxilliary /equipment/instrumentations prior to this event? Can you tell us : The sensor in question ? Tag name? type( axial radial vibration, sismic ..) and what values are displayed on HMI/I???as you saying that...

You may have look on this informations that can higlight some points: H5-05: Communication Fault Detection Selection Enables or disables the communications time-out fault (CE). If H5-05 is set to 1, a fault will occur if the master controller does not receive a response from the drive after...
