Woodward blended the original solid DSLC™ with another decade of application experiences in developing 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.
The Woodward DSLC-2™ control is a microprocessor-based synchronizer and load control designed for use on three-phase AC generators. The DSLC-2™ control combines synchronizer, load sensor, load control, dead bus closing system, VAR, power factor and process control, all integrated into 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 allowing easy DCS and PLC interfacing. Modbus RTU is available through a separate RS-485 port.
Slip frequency or phase matching automatic synchronizing with or without dead bus closing is selectable.
The DSLC-2™ control senses true RMS power and provides soft bump-less loading and unloading functions. It can either base load or set import/export/process power levels against the utility, or accurately share loads on isolated, multiple generator systems.
VAR and power factor control flexibility allows you to either provide a set level of VARs to the utility or to maintain a constant power factor for reliable operation. The VAR/PF control also shares kVARs in an isolated systems, maintaining proportional reactive loads (kVARs) on all machines more accurately than droop or cross-current voltage systems.
