9.2.4 Settings for the infeed (Active Infeed) under difficult line conditions
Description
The following setting examples are taken from commissioning procedures and are not
generally valid! The required control characteristics must be checked again after the settings
have been made.
Example 1: Infeed operates on a weak line supply
Infeed error during line identification, power failure (F6200, A6205)
Following procedure:
1. Exclude other sources of fault: e.g. actual power failure, wiring fault, correct supply data
setting (p0210, p0211)
2. Reset the infeed parameters, re-enter the supply data
3. p0281 Line supply overvoltage, alarm threshold = 120%
p0283 Line supply undervoltage, shutdown (trip) threshold = 75%
p0284 Line supply frequency exceeded, alarm threshold = 120%
p0285 Line supply frequency fallen below, alarm threshold = 80%
→ Start line supply ID (p3410 = 5)
4. If 3. was not successful, in addition:
Reduce the excitation current p3415[0] = 5%, p3415[1] = 5%
→ Start line supply ID (p3410 = 5)
5. If 4. was not successful, then in addition:
p3463 Infeed supply angle change phase failure detection = 30°
p3560 Infeed VDC controller proportional gain = 50%
p3603 Infeed current precontrol factor D component = 0 to 50%
p3615 Infeed current controller P gain = 50%
(individual parameters only visible in service access level)
→ start line supply ID
6. If 5. was not successful, then in addition:
Change the controller gain p3560 = 10 ... 300% (Vdc controller)
7. For operation with generators:
If no regenerative feedback is possible when generating: p3533 = 1 (inhibit generator
operation)
If required, the tolerance thresholds for frequency and voltage should be increased
further: p0281 ... p0285
