MSLC
Woodward’s Master Synchronizer And Load Control
Woodward’s MSLC control is a microprocessor-based load control designed for three-phase electric power generation sites equipped with our DSLC (Digital Synchronizer and Load Control) units 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.
Features include:
- Synchronizer and load control in one box
- Automatic plant loading and unloading for smooth load transfer to and from the utility
- Controls plant-wide import/export levels against the utility
- Overall power factor control
- Accurate control of non-linear and distorted utility lien wave forms
- Digital communications network for information exchange between MSLC and individual DSLC controls
