Dear all,

We are working on upgrading F9 GE turbine control system. I'm looking for information about synchronization card for Frame 9/Mark IV. The card part number is "DS3800NASB1BB1C - synch Iso". If anyone has any information like manual or datasheet, thank you for sharing it with me.

Many thanks

alizareian67,

If you are referring to the printed circuit board mounted on the upper right side wall of the Mark IV cabinet and you are working on a replacement turbine control system for the Mark IV using a non-GE turbine control system there's nothing to know about the card that will be of any use to you.

You need to look at the relevant sheets of the unit's Mark IV Speedtronic elementary to see the details of the signals (hardware and software) associated with the printed circuit card. Then you need to find or develop an automatic synchronizing function. Many manufacturers sell such equipment--Basler Electric, Schweitzer (sp?), Woodward, Siemens, and even GE. An automatic synchronizing function needs to have two voltage/frequency inputs: one from the generator terminals, and one from the grid the generator is being synchronized to/with. It needs to be able to raise- and lower generator terminal voltage to "match" the grid voltage, and it needs to be able to adjust the turbine-generator speed to be able to "match" grid frequency (speed and frequency of a generator are directly related). And, it needs to be able to calculate slip and phase angle and send the signal to close the generator breaker at the appropriate time (when voltage and phase angles are "matched" and in synchronism).

That's all there is to it. If you're replacing the Mark IV, and the Mark IV had the automatic synchronizing function/card, you need to replace that functionality by whatever means is acceptable to the Customer and the budget. Not difficult using off-the-shelf hardware and software.

Best of luck!

 

alizareian67,

The synch card is actually located on the left side wall of the Mark V (when looking into the panel from the open doors on the front of the panel).
