Woodward MSLC Master Synchronizer and Load Control Application

Introduction 
This manual describes the Woodward MSLC Master Synchronizer and Load Control. 
Application
The MSLC is a microprocessor-based overall plant load control designed for use 
in a system with Woodward DSLC™ (Digital Synchronizer and Load Control) 
controls on each generator to provide utility synchronizing, paralleling, loading, 
and unloading of a three-phase generating system. 

MSLC functions include: 
 Selectable for phase matching or slip frequency synchronizing between the 
utility and a local bus with voltage matching; 
 Automatic system loading and unloading for bumpless load transfer; 
 Import/Export level control capability; 
 Process control for cogeneration, pressure, maintenance, or other process; 
 Proportional loading of associated DSLC controls in isochronous load sharing; 
 Adjustable Power Factor control; 
 Built in diagnostics with alarm relay driver output; 
 Multi-function adjustable high and low limit alarms and adjustable load 
switches with relay driver outputs; 
 Digital communications network to provide loading and power factor control 
of individual DSLC equipped generators; 
 Full setup, metering, and diagnostic capability through a hand held 
programmer terminal (Figure 1-2).
