    GE Frame 6 Trip and Refinery Grid Disconnect Frequency

    Forgot to say - the sister was sharing the load so almost same on each machine before Hz drop GT1 - 36MW (and 103 t/hr HRSG production), GT 2 - 38MW (and 109 t/hr HRSG production). I am going to site next week and will see if I can dig up more data.

    GE Frame 6 Trip and Refinery Grid Disconnect Frequency

    Again, many thanks WTF. I will need to check more on rating data and site ambient at the time etc. For me, a big question mark is that its sister IDENTICAL machine running in parallel - also in droop - survived until after the 47.5Hz islanding and did not trip on high exhaust temp but other...

    GE Frame 6 Trip and Refinery Grid Disconnect Frequency

    Thank you very much WTF for such a comprehensive response. Quite a lot to unpick there and indeed I will engage further with the technicians at site to try to address some of the issues. It appears it is the set up on this individual machine because the (only other) second machine in parallel...

    GE Frame 6 Trip and Refinery Grid Disconnect Frequency

    I have been asked to look at the blackout of a refinery. It happened during a grid collapse when the frequency dropped to zero. Before the refinery could go into island mode, one of its main GE gas turbines tripped on High Exhaust temperature. It was operating in droop mode. It would have been...
