    Steam Turbine Emergency Overspeed Probes Not Sending Signal (2/3) - L14H_ZE

    Good morning, During a recent major outage, we replaced and rewired three primary and three emergency overspeed probes. We had high vibration during startup (another issue altogether) and had one of the emergency overspeed probe wires come loose, producing a 0 signal in the prevote logic. After...

    Reduced Power Operations of a Baseload Plant

    Plant MW control is set at ~124MW for our plant. We have 1 gas turbine and 1 steam turbine. What this does, is, if the GT is putting out, say 100MW, then the ST will put out 24MW. It is a setting for the ST that adjusts the MW output of the ST to make the total plant MW output equal to whatever...

    Reduced Power Operations of a Baseload Plant

    CSA, Thank you for your response. I downloaded the manual that you recommended and have started reading it. A lot of it is over my head at this point, but I will get there. As far as TTRF1 goes, I understand that this is what causes the operational mode change, but I'm not sure how far we...
