MSLC Master Synchronizer and Load Control - Home Mega Global ...

• Digital signal processing makes the MSLC resistantto power line distortions and harmonics• Digital communications across the LON reducesusceptibility to noise on the load sharing lines• Three-phase true RMS power sensing makes theMSLC accurate even with unbalanced phase loadingand voltage fluctuations• Local Area Network carries plant parameters for usein a distributed control systemOPERATING MODESSynchronizing—The MSLC controls all DSLC-equippedgenerators to match both frequency and voltage betweenthe local bus and the main, and then closes the utility tiebreaker when they are synchronized.Base Load—The MSLC talks over its LON to set allDSLC-equipped generators in isochronous load sharing toa chosen percentage of their individual rated loads andpower factor.Import/Export Control—TheMSLC controls real load andreactive power across theutility tie. Real load (kW) iscontrolled by changing theload levels; reactive load(kVAR) is controlled bychanging the power factorreference on all DSLCequippedsystem generatorswhich are in isochronous loadsharing.Process Control—TheMSLC control adjusts thereal load on the plantgenerators to maintain aprocess at a chosen level.ADJUSTMENTSThe Woodward Hand Held Programmer makes alladjustments quickly and easily through the control’s tenconvenient menus. The control saves all set points inpermanent memory, which does not require batteries orother power sources to retain data. The Hand HeldProgrammer prevents tampering with set points, yetallows entries to be changed at any time. The Hand HeldProgrammer displays in plain English, so there are nocodes to look up or memorize.• Menu 1–Synchronizer• Menu 2–Load Control• Menu 3–Load Limits and Switches• Menu 4–Process Control• Menu 5–Configuration• Menu 6–Calibration• Menu 7–Electric Parameters• Menu 8–Control Status Monitor• Menu 9–Discrete Inputs/Outputs• Menu 0–DiagnosticsTypical Wiring Connections
