The Woodward MSLC is a microprocessor based load control designed for three-phase electric power generation sites equipped with Woodward DSLC™ Digital Synchronizer and Load Controls which operate in parallel with the utility. The MSLC is a synchronizer, a utility load sensor, an import/export load level control, a power factor control, and a master process control.

The MSLC provides either phase matching or slip frequency automatic synchronizing of the local plant bus to the main power grid. The MSLC talks over its own LON (Local Operating Network using Echelon® LonWorks™ network technology) to control real and reactive loading against the utility by DSLC-equipped generators.

The MSLC's load sensor and load control sense true RMS power and provide bumpless loading and unloading against the power grid. They can either base load, set import/export levels, or maintain a plant process control.

The MSLC not only controls the kW loading on the utility tie, but matches plant voltage to the utility prior to paralleling. The control then maintains a chosen power factor or a set VAR import or export level on the associated generators equipped with VAR/PF-controlling DSLC units (or reduced function DSLC units).
If the MSLC is used with reduced function DSLC units, the DSLC units will not share
VAR/PF on an isolated bus (utility breaker open).
