Line reactors
for armature (DCS 50xB) and field
(DCF 50xB) supply
When thyristor power converters operate, the line
voltage is short-circuited during commutation from
one thyristor to the next. This operation causes voltage
dips in the mains (point of common coupling). For the
connection of a power converter system to the mains,
one of the following configurations can be applied:
With reference to the power converter:
The line reactors listed in table (2.6/1)
- have been allocated to the units nominal current
- are independent of converter's voltage classification; at some converter types the same line choke is
used up to 690 V line voltage
- are based on a duty cycle
- can be used for DCS 500B as well as for DCF 500B
converters
Configuration A
When using the power converter, a minimum of impedance is required to ensure proper performance of the snubber
circuit. A line reactor can be used to meet
this minimum impedance requirement.
The value must therefore not drop below 1% uk
 (relative short circuit voltage).
It should not exceed 10% uk
, due to
considerable voltage drops which would
then occur.
Configuration B
If special requirements have to be met at
the PCC (standards like EN 61 800-3,
DC and AC drives at the same line, etc),
different criteria must be applied for
selecting a line reactor. These requirements are often defined as a voltage dip
in percent of the nominal supply voltage.
The combined impedance of ZLine and
ZLR constitute the total series impedance
of the installation. The ratio between the
line impedance and the line reactor impedance determines the voltage dip at the connecting point. In such
cases line chokes with an impedance around 4% are
often used.
Configuration C
If an isolation transformer is used, it is
possible to comply with certain connecting conditions per Configuration B without using an additional line reactor. The
condition described in Configuration A
will then likewise be satisfied, since the uk
is >1 %.
Configuration C1
If 2 or more converters should be supplied by one
transformer the final configuration depends on the
number of drives in use and their power capability.
Configuration A or B has to be used which are based on
commutation chokes, if the drive system consists of any
of the converters
(C1, C2, A5, A6,
A7). In case only two
converters type A7
are involved no commutation chokes are
necessary because the
design of these converters is adapted to
that wiring
