Closed-loop thyristor current control
5-2 System- and communication configuring D7-SYS - SIMADYN D
Edition 06.2002
5.1 Overview
The documentation for the closed-loop thyristor current control is valid for
Step 7 with D7-SYS version V5.2.0 in conjunction with the CFC
program.
The closed-loop thyristor current control software can only run in
conjunction with the ITDC expansion module.
!
WARNING
The warning information/instructions in the Instruction
Manuals/Operating Instructions of the associated thyristor sets must be
carefully observed.
The closed-loop thyristor current control is a standard software package
for closed-loop armature current and field current controls of
single (1Q) or four-quadrant (4Q) DC drives.
The following functions are included in the standard software package
CFC Chart “D7-SPTCC”
Switch-over logic stage
Closed-loop armature current control
Closed-loop field current control
Gating unit
For a 6-pulse, line-commutated drive converter in a B6C or, for two 6-
pulse rectifiers in a circulating-current free, anti-parallel, fully-controlled
bridge circuit (B6)A(B6)C.
This standard software package exchanges ITDC signals with the
6QG2x/6QG3x SITOR sets via the SITOR interface -X7 of the expansion
module.
These standard software packages should be copied into the user project
and supplemented by the application-specific system data and
connections to the user program.
The gating unit comprises line supply synchronization, actual value
sensing and firing pulse generation and requires a clockwise rotating
field.
