This question is on behalf of my Plant Manager, and is directed to any 7EA plants with MK V that has had GE modify your controls for black start operation.
Our site has 8 units, 4 are black start capable and 4 are not.
We have what I think is a curious side effect on the 4 units with the controls modification, and I have been unable to get GE to comment as to whether this effect was by design or just the way the particular GE TA programmed our units.
On our non-black start units, we have the ability to select auto sync mode at any time during the start-up.
On our black start units, auto sync mode can't be selected until the unit has reached 95% speed. (basically FSNL)
I am interested if anyone else with the black start modification has this same limitation?
I have my own opinion as to whether you should or should not select auto sync earlier in the start-up process.
My main question isn't if you should or shouldn't, but rather can you on your black start units?
