SE_P34x_GEN
MiCOM P34x shaped generator element set: reverse power (ANSI 32), neutral-displacement stator earth fault (ANSI 59N / 64S 95 %) and over/under-frequency (ANSI 81), with first-out annunciation.
When to use it
Use SE_P34x_GEN when a synchronous generator — standby set, CHP unit, embedded generation — needs its motoring, stator earth-fault and frequency protection modelled in the PLC alongside the set controller and the real relay.
Interface

Supervised control write
SE_P34x_GEN commands a real actuator. It is written to sit underneath your own interlock, permissive and protection logic — not to replace it. Commission it as you would any control block you wrote yourself.

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.
