Woodward GC-3400XT Group Controller for large fleet of gensets

Description

Woodward’s group controller, GC-3400XT together with easYgen-3400/3500XT genset controller

and easYgen | LS-6XT circuit breaker controller is designed to manage virtually any large scale

power generation system you can imagine. The trio enables you to command up to 496 gensets,

with complete genset management, synchronization, dead bus prioritization, load share, load

dependent start/stop and segmenting capabilities to name a few. These controllers come with

stand-ardized software that is simple to configure, yet easily customizable for individual applica

tions. Peer-to-peer communication between the controls and load share line redundancy at each

level ensures single-fail-safe op-eration of your power generation control system.

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.
