MSLC-2XT

Product Overview

Woodward’s MSLC-2™ functions with the DSLC-2™ control to provide synchronization and load control across Utility and Intertie breakers.

Key Features

• ✓Woodward’s MSLC-2™ functions with the DSLC-2™ control to provide synchronization and load control across Utility and Intertie breakers.
• ✓The MSLC-2/DSLC-2 combination operates over an Ethernet communication network to control simple or complex generator system applications.
• ✓This combination, 32 DSLC-2’s and 16 MSLC-2’s, provide multiple unit, multiple segment, utility and intertie power management for complex power systems.
• ✓Controls plant wide import/export levels while always providing bump-less load transfers with utility.
• ✓The MSLC-2 control combines synchronization, dead bus closing, utility/intertie load sensor, baseload control, import/export control, VAR, power factor, and a master process control in one powerful package.
• ✓The MSLC-2 provides phase matching or slip frequency synchronization, with voltage matching, across a utility or intertie breaker.
• ✓The MSLC-2/DSLC-2 combination can handle multiple utility connections with a maximum of 8 bus segments in one application.
• ✓The MSLC-2’s load sensor and load control sense true RMS power and provide a bump-less loading and unloading against a utility grid.
• ✓Baseload, import/export, process, and utility unload modes control the KW power between different power sources at the same time controlling the reactive power, VAR and power factor.
• ✓Reactive power is also ramped on and off for the smoothest load transactions between power grids.
• ✓The MSLC-2 communicates via Ethernet, with redundant Ethernet now available, to control real and reactive loading against the utility by DSLC-2 equipped generators.
• ✓The tie breaker mode allows synchronization between multiple generator systems.
• ✓Segments are connected and power can be measured across an intertie, but no load control is functional when in Tie breaker operation.
• ✓One MSLC-2 can provide master control for up to 32 DSLC and an additional 15 MSLC-2 in a system.
• ✓Two dedicated Ethernet lines for precise system communications between all DSLC-2’s and MSLC-2’s on the system.
• ✓Ethernet Modbus TCP for remote control and monitoring by PLC or DCS system.
• ✓Redundant Ethernet communications for enhanced reliability.
• ✓Master MSLC-2 redundancy, loss of communications with the designated MSLC-2 master initiates control hand off to the next designated MSLC-2 master.
• ✓The MSLC-2 hardware is adjustable for multiple applications.
• ✓Slip frequency or voltage phase matching synchronizing fully selectable with dead bus option in both directions provide full flexibility for intertie and main-tie-main applications.
• ✓Having functions integrated into one box eliminates the need for redundant sensors (like PTs, CTs, and MOPs) that connect to individual modules such as the load sensor and synchronizer.
• ✓Digital signal processing makes the MSLC-2 resistant to power line distortions and harmonics.
• ✓Three-phase true RMS power sensing provides accurate readings even with unbalanced phase loading and voltage fluctuations.
• ✓Export/import control over multiple utility MSLC-2’s in same segment.
• ✓The Woodward ToolKit™ software allows flexible setup using the same basic menu tree as the original MSLC plus an overview screen.
• ✓No hand held programmer is required.
• ✓Graphical overview of generators and bus bar parameters with trending makes the MSLC-2 commissioning friendly.
• ✓The Toolkit can be accessed either via one of the Ethernet ports or via RS-232 port.
• ✓Phase angle compensation provides adjustment for additional deviation correction across a transformer.
• ✓The system update feature allows for system reconfiguration.
