Thread: ALC Source

  1. #1

    Default ALC Source

    I have a question for ALC for power transformer?
    That the ALC sources can come from each sides of transformer and change different color for each sides. I tried to use link to connection between sides but it did not work.
    I read the manual and tried someway but sometime it worked, some time it did not.
    Could you give me some idea about it?

    Hi mytom!

    Which zenon version are you using?

    Usually your grid is coloured depending on the ALC configuration made at project properties > automatic line colouring.
    If your transformer is configured to be provide colours only for feed-forward and you try to do a reverse feed while having the source for reverse feed set to UNDEFINED[0] parts of the grid in reverse direction are not coloured.
    Same applies when configuring reverse feed only, but in this case the feed-forward part is not coloured.

    Some suggestions that might help:
    - The direction for ALC-colouring is always starting at the left upper corner going down to the right lower corner
    - Ensure that all elements (especially lines and combined elements) have option "Use colour from ALC" set
    - Configuration of sources for both, feed-forward and reverse feed at transformers
    - Three-winding transformers might consist of multiple ALC-elements (transformer elements as well as lines); ensure that all elements have option "Use colour from ALC" set as mentioned above, especially when using it within a symbol
    - It might be necessary to switch the input/output of the transformer if the transformer does not support reverse feed

    Documentation for your product can be downloaded from here (requires having a customer account):

    Best regards,

    - do not use in your topology the ALC sources reserved in zenon for internal use (ID <=10). Create in Project - ALC Configuration your own Sources (ID >= 11) and link only these sources with your ALC elements (Source, Generator, Transformer).
    - link Combi-elements representing Transformers (or Sources, Generators etc.) with internal variables having initial value 1 (not 0).
