Woodward easyYgen LS-6XT: A Multi Circuit Breaker Control Solution for Complex Power Management

Introduction

In today's highly dependent industrial and commercial environment on stable electricity, the reliability, flexibility, and intelligent management of power generation systems have become crucial. The easyYgen LS-6XT controller launched by Woodward is an advanced synchronization and protection control device designed to address complex power management challenges. It not only integrates powerful grid disconnection and protection functions, but also ensures high availability of critical power assets through redundant communication architecture and the ability to support large-scale networks. This article will provide a comprehensive and in-depth analysis of LS-6XT from multiple dimensions such as technical specifications, functional features, application architecture, and market positioning, aiming to provide a detailed technical and application reference for system integrators, OEM manufacturers, and end users.

Product Overview and Core Positioning

Woodward easyYgen LS-6XT is defined as a synchronous controller that integrates main network disconnection and protection functions. Its core design goal is to serve application scenarios that require high reliability and complex power management, such as:

Peak Shaving

Import/Export Control of Electricity

Isolated&Utility Parallel

Control of multi-channel mains power supply, bus tie circuit breakers, and generator groups

LS-6XT can seamlessly collaborate with Woodward's easyYgen-3400XT/3500XT series generator set controllers and easyYgen | GC-3400XT unit group controllers to build a hierarchical control system from a single generator set to the entire power plant level. Its redundant bus communication capability (supporting CAN ETH and Eth ETH redundancy) effectively avoids single point failures and significantly improves the availability of the entire power generation system.

The controller adopts a sturdy aluminum powder coating shell, integrates a customizable LED indicator panel, and supports remote operation and monitoring through independent Ethernet connection to Woodward easyYview visualization panel. The hardware design of LS-6XT supports standardization, helping OEM switchgear manufacturers, generator set manufacturers, and system integrators unify hardware platforms in various grid connected or islanded operating applications, reducing costs and complexity.

Detailed explanation of core technical characteristics

1. Strong network and scale support capabilities

LS-6XT demonstrates excellent system scalability:

Up to 64 LS-6XT controllers can work together in a single network.

Can connect up to 32 easyYgen-3400XT/3500XT unit controllers.

It can manage up to 16 GC-3400XT unit group controllers, with each group containing up to 31 generator units.

In an application project, it is possible to control up to 64 circuit breakers on up to 128 bus segments.

This scale support capability enables it to easily handle various applications ranging from small backup power systems to large industrial power plants.

2. Accurate measurement and synchronization function

Three independent true RMS AC measurements: used for system A voltage, system B voltage, and auxiliary voltage respectively to ensure comprehensive monitoring.

High precision measurement: The voltage and current measurement accuracy reaches level 0.5, and the power measurement accuracy reaches level 1.0, meeting the high standard measurement requirements.

Flexible synchronization method: Supports phase matching or slip frequency synchronization, and has voltage matching function to ensure smooth grid connection.

Vector group adjustment: During the synchronization process, the vector group can be adjusted to adapt to different transformer connection methods.

Active synchronization (supported by some models): It can actively control the frequency and voltage of the generator to match the power grid, achieving fast and smooth grid connection.

3. Advanced circuit breaker control and operation mode

Remote selectable circuit breaker switching mode:

Open Transition

Closed Transition (short-term parallel<100ms)

Inter change conversion

Long term parallel operation (Indefinite Parallel)

Support single or dual circuit breaker control logic to adapt to different main wiring schemes.

Generator group circuit breaker (GGB) control facilitates overall scheduling of the unit group.

4. Comprehensive protection function

The LS-6XT is equipped with a variety of protective components, equivalent to multiple ANSI protection codes, including but not limited to:

Overvoltage/undervoltage, overclocking/underflocking protection (59, 27, 81O, 81U)

Voltage imbalance protection (47)

Phase mutation and frequency change rate protection (78, 81- ROCOF)

Synchronization check (25)

Power Direction Protection (32R) - Some models support it

Instantaneous/timed overcurrent protection (50, 51/51V) - supported by some models

Load imbalance protection (46) - supported by some models

Q-V monitoring and time-dependent voltage protection

These protection features can be customized through Flexible Limits to meet the protection needs of specific projects.
