Do you want to build a
Ring Bus application with +32  generators and many more?

Here is how to connect +32 generators:

One GroupController GC3400XT is added to each powerplant and used as smart an IED (intelligent electronic device) load share gateway collecting all easYgen-3500XT within this group.

No need to connect current and voltage sensing but can be wired.

GC-3400XT's Group breaker is always seen as closed, as there is no physical group breaker 

All GC3400XT communicating via Ethernet B & C redundant Ethernet to other GC-3400XTs.

Each GroupController communicate via CAN Ethernet A  to each easYgen-3500XT within the group.

Each GroupController can placed within the group where it is convenient.

GroupControllers LDSS (Load dependent start & stop) functionality can be used to sequence individual  gensets within each group. 

Layer 1 n+1 easYgen-3500XT controls within one group are connected to  above GC-3400XT in Layer 2.

Ring Bus Couplers &  incoming Mains Feeders  can be served by LS-6XT in Layer 3 as well:

Layer 1 n+1 easYgen-3500XT controls within one group are connected to  above GC-3400XT in Layer 2
