Using vector group 5 (Dyn5) implies: α = 5 x 30° = 150°. Since 150° < 180° and the
easYgen busbar measurement is connected to the high voltage side, this results into "α"
to be used as phase difference. Configure parameter "Phase angle GCB" (parameter
╚═▷
8824 ) to "150°" to compensate the phase difference between generator/busbar.
Example – phase angle compensation MCB
Fig. 259: Phase angle compensation MCB
The easYgen mains voltage is connected to the high voltage side of a transformer with
the vector group Yd11. The easYgen busbar voltage is connected to the low voltage side.
Because of the transformer, the phase angles between mains and busbar differs due the
closed MCB. The synchronization function of the easYgen can be compensated by a
configurable phase angle deviation.
Using vector group 11 (Yd11) implies: α = 11 x 30° = 330°. Since 330° > 180° and the
easYgen mains measurement is connected to the high voltage side, this results into
"-360° - α" to be used as phase difference. Configure parameter "Phase angle MCB"
(parameter
╚═▷ 8842 ) to "-30°" to compensate the phase difference between mains/
busbar.
