CROSS_CURR_COMP
Cross-current (reactive differential) compensation loop for droop-less kVAr balance between paralleled machines.
When to use it
Use CROSS_CURR_COMP when the CT secondaries of two or more paralleled machines are looped in series so each AVR sees only its own reactive current MINUS the loop average, and the bus voltage must not droop with VAr load.

Create a free Ri Tech account to download the block. You get the Structured Text body, the Rockwell Add-On Instruction (.L5X), the Schneider Control Expert DFB (.XDB), PLCopen XML, the IEC 61499 function block type (.fbt) and the datasheet.
Every block in the catalogue is free to download, in every format, with no purchase and no card. Browsing needs no account at all; downloading needs a signed-in one, so the block lands in your library and re-downloads whenever you need it.
Source is never published on this page. The implementation is released to a signed-in Ri Tech account — free of charge, but never anonymously.
