New ProAct (RoHS Compliant)
This manual describes the Woodward ProAct Digital Speed Control and ProAct 75° electric powered actuators, Models I and II.
Single control part number, supporting ProAct Models I and II
- SP
| DESCRIPTION |
| Woodward’s DSLC-2XT synchronizes and controls the generator loading for up to 32 three phase AC generators using the integrated (DSLC-2XT/MSLC-2XT) Ethernet communication network. The DSLC-2XT excels in either simple generator or complex generator system applications. The DSLC-2XT/MSLC-2XT combination provides multiple units, segment, utility, and intertie power management for complex power systems. |
| The DSLC-2XT 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. Ethernet network A provides dead bus closing, load sharing, and VAR sharing information between DSLC-2XT and MSLC-2XT units. Ethernet ports B/C provides customer remote control and monitoring capability using Modbus TCP allowing easy DCS and PLC interfacing. The Ethernet network provides each device the capability to monitor all other devices on the network. If the Ethernet network is compromised, an alarm is provided and the system can be transferred to a droop control mode |
| Redundant load sharing is selectable using both Ethernet A and B networks for enhanced reliability. If one network is compromised, the system automatically switches to the second network. Slip frequency or phase matching automatic synchronizing with or without dead bus closing is selectable. Permissive mode provides synch check relay functionality. |
| The DSLC-2XT 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 system, maintaining proportional reactive loads (kVARs) on all machines more accurately than droop or cross-current voltage systems. |
| FEATURES |
| Dedicated Ethernet network for precise system communications between all DSLC-2XT’s and MSLC-2XT’s reduces system wiring. |
| Ethernet Modbus TCP, and Modbus RTU, for remote control and monitoring. |
| Redundant Ethernet communication for enhanced reliability. |
| The “system update” feature allows for removing or adding generator sets |
| Integrated DSLC-2XT and MSLC-2XT system functionality eliminates the need for redundant sensors (like PTs, CTs, and MOPs) that connect to individual modules such as the load sensors and synchronizers. |
| Back panel mounting and a reduced size frees up door space and provides easy wiring. |
| Eliminates the need for additional relay logic to control dead bus closing. |
| Slip frequency paralleling, voltage matching, and speed bias transfer between the synchronizer and load control result in smooth paralleling without the risk of reverse power trips. |
| Three-phase true RMS power sensing makes the DSLC-2XT control accurate even with unbalanced phase loading and voltage fluctuations. |
| Phase angle correction for GCB when a transformer is included in the system |
| The Woodward ToolKit™ software allows flexible setup using the same basic menu tree as the original DSLC-2 plus an overview screen. Graphical overview of generator and bus bar parameters with trending makes the DSLC-2XT commissioning friendly. All the Woodward devices can be programmed from a single connection to the network. |
| The ToolKit can be accessed either via one of the Ethernet ports or via USB port. |
