(OP)
does anyone know what intercept valve referance means in a general electric mark vi turbine control system?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: ge mark vi turbine control system
Some times some people interchange the phrase "referance" for "EsubL-IV". Also "CV reference" can be confused with "load set" and when there is no loading rate control the two are the same

RE: ge mark vi turbine control system
As stated the CV reference and IV reference are ganged together, in fact they are same value, the CV reference is summed with a set 100% bias to derive the IV reference. a 0% CV reference will will have the IV's 100% open, and a -30% CV reference will have the IV's at 0% open.
Thus set the CV referance to -30% and speed error will control the IVs near 0% open to roll the unit. once "at set speed" rated, the CV referance will be increased, increasing the IV referencae to synch and load the unit. as the IVs open and increase load, the CV referance will be approaching 0%, once IVs are at 100%, the CVs will be opening and continue to increase load.
That would be my guess.
Sounds like an interesting system, much more so than the straight forward speed control units I put into service 20 years ago.
