Chapter 3 – Twelve–Pulse Parallel
Configurations with DCS 600
The following figures show the most significant features of the 12 –
pulse hardware configurations with two DC thyristor power
parallel
converters of the
DCS 600
12 – pulse control structures:
•
Connection of converters in parallel configuration
•
Use of a T-reactor [for 12 – pulse parallel configurations]
•
Master / Follower link [channel 2 on SDCS-AMC-DC boards]
•
Master / Slave 12 – pulse communication link [channel V260 on
SDCS-CON-2 boards]
