Woodward's easYgen-3500 Series paralleling genset controllers provide exceptional versatility and value for OEM switchgear builders, generator packagers, and system integrators. The easYgen-3500 combines complete engine-generator control and protection with advanced, peer-to-peer paralleling functionality and innovative features in a robust, attractive and user-friendly package. Its integrated LogicsManager™ programmable logic functionality provides outstanding application flexibility and can often eliminate the need for additional PLC control, yet can easily integrate with SCADA or PLC-based control systems where desired.

The easYgen-3500 gives you the advantage of standardizing on a single, affordable genset controller for many different distributed power generation applications--from stand-alone emergency backup power to parallel load sharing of up to 32 gensets in complex, segmented distribution systems with multiple utility feeds and tie breakers.

Common easYgen-35400 applications:

Emergency standby: data centers, hospitals, commercial and industrial facilities

Distributed Generation (DG): utility-dispatchable power for peak demand response

Islanded prime-power: oil & gas exploration, marine, remote villages, rental/mobile

Microgrid: military, government, net-zero communities, universities

Utility paralleling: peak shaving, demand curtailment

Cogeneration (CHP): wastewater treatment, biogas production/containment

Switchgear upgrades: generator control retrofit to add load sharing/paralleling capability

easYgen-3500 Features & Benefits

All easYgen-3500 Series models include these standard features:

True RMS voltage and current sensing (gen, bus and mains) for reduced susceptibility to harmonics

CAN network communication/control to engine ECU (standard SAE-J1939 protocol and several proprietary engine OEM protocols are supported)

Serial Modbus RTU (slave) communication for SCADA annunciation and external control

Configuration via PC/laptop with Woodward ToolKit service tool

Connectivity with the RP-3500 Remote Panel for complete annunciation, control and configuration of the easYgen-3500 controller, over CANopen protocol at up to 250m distance

Compliance agency/marine* approvals: CE, UL/cUL, CSA, BDEW, ABS, Lloyd's Register

(* see marine package for further approvals)

The easYgen-3400 Series provide:

AMF (automatic mains failure) detection, decoupling and emergency run with dead bus close

Automatic synchronization: phase-match, positive/negative slip-frequency, run-up (dead field) paralleling

Circuit breaker close/open control: GCB only, GCB and MCB (ATS function), or external (no) control

Proportional load sharing (isochronous or droop) of up to 32 gensets, regardless of individual size

Base loading, import/export control, asymmetrical loading (through external base load input)

Automatic load dependent start/stop for improved generation system efficiency

Asynchronous (induction) generator control

Engine and generator protection functions, with fully programmable settings

Woodward Inc. is responsible for the development and production of a large-spanning range of industrial generator modules, from speed and loading control to voltage regulator modules. This unit is a part of their SPM-D11 category of synchronizers, and designated under the numerical ID of 8440-1706. The 8440-1706 model is outfitted with the capability to provide units with a combined synchronizing ability for a circuit breaker, power factor and load factor control, and the option for isochronous load sharing and generator protection. The 8440-1706 unit is also built with a choice for operators to implement while the generator voltage matching is occuring; either the phase matching can also occur, or the slip frequency synchronization can be enabled. The mains parallel operating features the 8440-1706 is included with is a wide range of features. There is the real power control, the true RMS power calculation, as well as the soft unload feature, and the power factor control and setpoint by the adjusted parameters. This unit is also outfitted with isolated operation control features and dead bus operation features. The 8440-1706 is designed with the standard dimensions, measuring at 144 millimeters by 72 millimeters by 122 millimeters. It weighs at least 800 grams, or 1.76 lbs. The integrated LCD display has a two-line display, and provides users with information for system diagnostics and alarms.
