LOAD_SHARE_KVAR

Reactive (kVAr) load sharing over a share network by AVR voltage trim — parallel machines without circulating current.

Validated application blockGen · Load SharingIEC 61131-3IEC 61499v1.0.0

When to use it

Use LOAD_SHARE_KVAR when paralleled machines must share reactive load in proportion to their kVAr ratings while the AVRs hold a common bus voltage, and reactive droop is not wanted because the bus voltage must not sag with VAr load.

Download LOAD_SHARE_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.
