We are having a Mark Vie System for our gas turbine (S/N: 296462, Frame VI machine) control and was commissioned in Feb.2012. The Mark-Vie system FDM No.: F705G1.
Recently our GT was in shutdown and Mark-VIe panel was powered off for Shutdown activities in the field for about two days. Before switching off the power to MK-VIe system it was health and there were no problems in the system.
But on 27/10/2013 at around 6:30pm when it was switched on following problems observed.
(1) During startup <S> controllers could not booted for a long time. It is observed that it got booted after <T> Controller get booted and becomes healthy. It was taking more than 20 minutes or so to get booted after <T> controller becomes healthy.
(2) During and after complete booting of all three controllers it is observed that various PDIA 6 nos, PDOA 5 nos, PAIC 1 number, PPRO 1 number, PPDA 1 number etc are not communicating with controller. They are giving communication error. Remain in ‘Attn’ red LED blinking. Even one number controller UCSA not getting booting.
With this problem we could not start our machine and other start up activities.
It is our humble request to let me know the reasons of above mass failures at a time. Anybody have faced such failures?
We had to urgently procure and repalce the modules to start plant.
Kindly note that power supply, earthing system and power ON sequence are as per recommendations by OEM.
Such a big failure is very uncommon in GE system. Have anybody got repaired failed modules and got analysis reports for root cause analysis.
Kindly share your views, suggestions and experience.
