Woodward easYgen-3400XT/3500XT Genset Control for Complex Paralleling Operation applications

The control combines complete engine-generator con

trol and protection with advanced, peer-to-peer paralleling functionality and innovative features in a robust, at

tractive, user-friendly and all-in-one package. The easYgen-3500 XT controls are designed to direct connect up

to 690Vac and operate to 4000m above sea level without derating.

The easYgen-3500XT is available in two packages. P1. focused at complex paralleling applications provides

redundant Ethernet communication, LS-5 connectivity, and standard I/O set, while P2. Co-Gen/CHP model

offers expanded onboard I/O set, 3-ph busbar voltage measurement capability and phase rotation monitoring

between gen-busbar and busbar-utility. These packages are available without a display in a rugged metal hous

ing suitable for back panel installations (easYgen-3400XT-P1 and easYgen-3400XT-P2 respectively). A sophis

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

A version of easYgen-3500XT (easYgen-3500XT-P1-LT and easYgen-3500XT-P2-LT) is designed to operate

down to -400 C for outdoor applications.

Woodward easYgen-3400XT/3500XT Genset Control for Complex Paralleling Operation DESCRIPTION

DESCRIPTION

Woodward raised the standard in genset paralleling control and power management system with the easYgen

3000XT Series controllers. These controllers come with standardized software that is simple to configure, yet

easily customized for individual applications. Enhanced connectivity enables fast, reliable and secure interfac

ing to other controls and communications systems while the enhanced hardware is a drop-in replacement for

previous generation easYgen-3000 Series Controls.

Targeted at enabling complex power management applications, the easYgen-3500XT supports easYgen | GC

3000XT to manage a large genset fleet of up to 496 sets and easYgen | LS-6XT to control up to 64 synchroniz

ing breaker or manual switches on up to 128 complex bus segments. Redundant load sharing is selectable us

ing Ethernet B and C networks for enhanced reliability. The control combines complete engine-generator con

trol and protection with advanced, peer-to-peer paralleling functionality and innovative features in a robust, at

tractive, user-friendly and all-in-one package. The easYgen-3500 XT controls are designed to direct connect up

to 690Vac and operate to 4000m above sea level without derating.

Static frequency converter For rail electrification FEATURES

BENEFITS & FEATURES

• Avoid unbalanced grid loads and resulting penalties to grid operators

• Provide reactive power control on grid and traction networks

• Increase of efficiency e.g. by reduced power consumption in railway system

• Reduce complexity for rail operator by eliminating the neutral section in overhead

catenary lines

• Flexibility to connect rail grid to power grids of different providers and to grids of reduced

voltage or short-circuit capacity

• Facilitate management of brake energy by sending back braking energy from catenary

to the grid

• Increase distance between substations

An SFC provides multiple features, including independent reactive power control for both grids

and the capability to supply the railway from a weak three-phase grid with low short circuit

power, ensuring perfect voltage balancing between phases.

It synchronizes the SFC along the line using the Phasor Management Unit (PMU), such as the

GE Vernova Multilin N60. which assists in balancing power across substations. The system is

protected by protection and control relays like the GE Vernova Multilin Agile. Additionally, it

supervises and manages the entire traction power supply to optimize availability. Faults along the

line are located using Travel Wave Form Localization (TWFL) technology, enabling faster recovery

of line supply.

Static frequency converter For rail electrification SFCs

As reducing carbon emissions becomes a more pressing issue,

populations are looking for a way to reduce their travel emissions.

Electric railways are recognized as the optimal solution due to their

superior energy efficiency, reduced emissions, and lower operating costs.

This trend is supported by public investments as the rail operators need to increase

power capacity, pushing to upgrade old 3 kV DC distribution networks to 25 kV AC.

In certain countries, the single-phase railway network historically operates at a

frequency distinct from that of the public grid, rendering direct connections between the

two networks unfeasible and requiring frequency conversion.

In contemporary applications, Static Frequency Converters (SFCs) are employed when

the power capacity of the grid network serving the rail line is constrained or the cost and time

to bring a high voltage powerful grid network is prohibitive.

Additionally, some new rail line projects are integrating SFCs for enhanced system optimization.

Static frequency converter For rail electrification

Power Conversion & Storage solution to help otimize power connections and stabilize catenary power

distribution.

Operators are increasing voltage from 3 kV to 25 kV to increase line capacity and reduce substation

counts.

A Static Frequency Converters (SFC) is an enabler of this transition,

particularly where the network grid capacity is limited.

Helping to connect to lower voltage connection to the grid, saving costs and deployment time.

To balance high renewable energy penetration in grid energy mix,

for greenfield projects (newly created lines), SFC substations can help ensure excellent

power quality from the grid, balance power between substations to avoid localized peaks,

facilitate power exchange between trains, and increase distance between substations,

reducing costs to connect to the transmission network.

SFC permits to decouple frequency and phase between

the catenary and the grid connections, enabling to

remove neutral sections along the catenary.
