The GC-3400XT is based on a scalable multi-master control concept to combine up to 31 easY

gen-3000XT equipped gensets with one group controller in a group. The groups are scaled up

to 16. i.e. a total up to 496 gensets can be managed in an application. The data flow within the

group is handled by CAN or Ethernet or CAN & Ethernet bus. The group controller collects and

sorts the data of its group and acts like a “Big Genset” control to the other GCs. The data flow

among the group controllers is handled by second communication bus Ethernet B or Ethernet C

or Ethernet B & C. Through the decoupling of the overall data flow, the bus bandwidth is kept low

and the single genset operation is kept safe, should a group controller become the point of failure.

Furthermore, the group controller may handle a group breaker, to synchronize or prioritize dead

busbar closing. Additionally, the group controller supports the synchronization and soft loading/

unloading of a tie- or mains breaker. Comprehensive diagnostics, monitoring and system update

function are implemented to help fast com-missioning of the system.

Woodward’s easYgen-3400XT/3500XT is an exceptionally versatile genset control with complete

engine-generator control and protection, genset breaker synchronization, dead bus arbitration

and isochronous/droop load share capabilities. The easYgen-3500XT is available in two packages,

P1 and P2. both are compatible to work with GC-3400XT. Both the packages are available without

a display in a rugged metal housing suitable for back panel installations. A sophisticated touch

screen remote panel (RP-3000XT) complements them as an operator control panel.
