DSLC-2

Woodward’s Digital Synchronizer and Load Control

The Woodward DSLC-2™ (Digital Synchronizer and Load Control) is a microprocessor-based synchronizer and load control designed for use on three-phase AC generators. The DSLC-2 combines synchronizer, load sensor, load control, dead bus closing system, VAR, power factor and process control, all in one powerful package.

Applications allow up to 32 generators to be precisely paralleled and controlled. A dedicated Ethernet system provides seamless communications between DSLC-2™ and MSLC-2™ units. A second Ethernet port is provided for customer remote control and monitoring capability using Modbus TCP, and allowing easy DCS and PLC interfacing. Modbus RTU is available through a separate RS-485 port.

Woodward used the original solid DSLC combined with an additional decade of application experience, to develop the new DSLC-2. The DSLC-2 excels in either simple generator or complex generator system applications. The

DSLC-2/MSLC-2 combination provides multiple unit, segment, utility, and intertie breaker control for complex power systems.

Features include: 

• Synchronizer and load control in one box
• Phase match or slip frequency synchronization with voltage matching
• Applications for up to 32 generators using 32 DSLC-2™ units and up to 16 MSLC-2™ controls
• Complex applications with up to 8 bus segments are possible
• One Ethernet port for unit-to-unit communications
• Second Ethernet port for remote control and monitoring via Modbus TCP
• Automatic generator soft loading and unloading for smooth load transfer
• Process control
• Isochronous load sharing with other DSLC-2 equipped sets
• Application range up to 999 MW
