Woodward MSLC-2XT ™ Main synchronizer and load controller

Woodward MSLC-2XT ™ Main synchronizer and load controller

Product basic information

Product Name MSLC-2XT ™  Master Synchronizer and Load Control

Core positioning and DSLC-2XT ™ Cooperate to achieve power system control with multiple generators, multiple segments, and multiple main/connecting circuit breakers

Adapt to complex industrial power systems and ship power systems (ABS/LR classification certification)

Certification qualifications UL/cUL, CE, CSA, EAC, ABS Type Approved, LR Type Approval

Alternative compatibility can directly replace the old version MSLC-2, supporting mixed use of old and new devices (Woodward update file required)

Core functions and features

(1) Synchronization and closing control

Synchronization mode: supports two optional modes: phase matching and slip frequency synchronization

Non voltage busbar closing: Bidirectional support for non voltage busbar closing function, suitable for contact circuit breaker scenarios

Phase angle compensation: It can compensate and correct the phase deviation caused by transformers

Segmented synchronization: supports synchronous control between 8 bus segments and inter segment communication

(2) Power control function

Active power control

Mode: Base load control, import and export power limitation, no impact load transfer (between grid/generator)

Accuracy: Three phase RMS measurement, resistant to voltage fluctuations and three-phase imbalance effects

System level control: capable of controlling the import and export power levels of the entire plant across multiple MSLC-2XT

Reactive power control

Control objects: VAR (reactive power), power factor (PF)

Features: Smooth switching of reactive power to avoid grid impact during load transfer

System level control: supports unified control of power factor throughout the factory

(3) System Expansion and Compatibility

Upper limit of system size

Generator: Up to 32 units (DSLC-2XT required)

Main/contact circuit breakers: up to 16 units

Busbar segmentation: up to 8, supporting automatic segmentation recognition

Communication compatibility
