ACA 635 IGBT Supply Sections 6-5
The parameters concerning the identification routine are presented
below.
Charging When the control has received a start command, the charging
contactor is closed. After the DC link voltage is high, the main
contactor/breaker is closed and the charging contactor is opened. This
procedure is controlled by the NAMC board via NIOC board digital
outputs R01 to R03.
If the charging is not completed, i.e. the DC link voltage has not
exceeded the value of Parameter 30.12 DC UNDERVOLT TRIP or the
charging current is not below 5% of
I
1base10s/60s
, a fault is set
(Parameter 9.11 SUPPLY FAULT WORD bit 0 CHARGING FLT ) .
Synchronization The ISU is synchronized to the network by two three-phase short-
circuits of 200
m
s in length at an interval of 6 ms. On the basis of the
short-circuit current, the ISU can identify the phase order of the supply
network and the starting point for the flux/voltage vector. The phase
order of the supply can be changed without performing the
identification routine again. The ISU must be stopped during a phase
order change.
The synchronization can also be done with only one 200
m
s short-
circuit by Parameter 99.06 FAST SYNC selection YES. Note: In this
case no phase order check is performed.
If a synchronization trial fails, the ISU makes up to 9 additional trials.
One reason for a failed synchronization is too low a short-circuit current
due to the high impedance of the network.
