Efficiency VSD vs. Fluid Couplings
06 Feb 2012
> 2% better efficiency of VSD solution, compared to Variable-Speed Planetary Gear@ nominal conditions, far better under part-load conditions!

Significance of Higher VSD Efficiencies at Part Load on Variable Cost; The Largest Portion of the Iceberg
Economical evaluation based on a full Life Cycle Cost analysis has to be performed for all alternative technologies
Fixed Cost:CAPEX- Analysis: considering all overall installation costs, like
costs for compression train, building, grid connection Install.&Comm. ,Permit
Variable Costs:OPEX-Analysis: costs for energy, personnel, buildings, emmissions,
interest rates, downtimeMAEX-Analysis: spare parts, personnel, downtime

Why VSD?
Better efficiency Less cooling needed Lower inrush current from supply Better dynamic response Environmental friendlier Less space required at motor Larger speed control range Load sharing between parallel units
Electrical VSD
Higher losses, less efficiency
More cooling capacity required
Network impact at DOL start
Space required between motor and machine
Higher total operating costs
