Woodward MSLC-2™ Master Synchronizer and Load Control

DESCRIPTION

Woodward’s MSLC-2™ functions with the DSLC-2™ control to provide synchronization and load

control across Utility and Intertie breakers. The MSLC-2/DSLC-2 combination operates over an

Ethernet communication network to control simple or complex generator system applications. This

combination, 32 DSLC-2’s and 16 MSLC-2’s,  provide multiple unit, multiple segment, utility and

intertie power management for complex power systems. Controls plant wide Import / Export levels

while always providing bump-less load transfers with utility.

The MSLC-2 control combines synchronization, dead bus closing, utility/intertie load sensor, base

load control, import/export control, VAR, power factor, and a master process control in one power

ful package.

The MSLC-2 provides phase matching or slip frequency synchronization, with voltage matching,

across a utility or intertie breaker. The MSLC-2/DSLC-2 combination can handle multiple utility con

nections with a maximum of 8 bus segments in one application.

The MSLC-2’s load sensor and load control sense true RMS power and provide a bump-less load

ing and unloading against a utility grid. Baseload, import/export, process, and utility unload modes

control the KW power between different power sources at the same time controlling the reactive

power, VAR and power factor.  Reactive power is also ramped on and off for the smoothest load

transactions between power grids.

The MSLC-2 communicates via Ethernet, with redundant Ethernet now available, to control real

and reactive loading against the utility by DSLC-2 equipped generators.

The tie breaker mode allows synchronization between multiple generator systems. Segments are

connected and power can be measured across an intertie, but no load control is functional when in

Tie breaker operation.
