DROOP_KVAR
Voltage (reactive) droop characteristic — the AVR voltage reference falls in proportion to exported kVAr.
When to use it
Use DROOP_KVAR when paralleled machines must share reactive load without a share line or a cross-current CT loop, and a small steady-state sag in bus voltage with VAr load is acceptable.

Download DROOP_KVAR — free
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.
