Title:
IMPROVED INTERNAL ELECTRIFICATION SCHEME FOR POWER GENERATION PLANTS
Document Type and Number:
WIPO Patent Application WO/2011/059425
Kind Code:
A3
Abstract:
It is presented an apparatus for use in an electrical power generation plant. The apparatus comprises: at least two adjustable speed drives, each connected, on an alternating current side, to an associated auxiliary motor; at least one reactive power consuming auxiliary device connected to an alternating current bus; a controller; and a converter for converting alternating current to direct current or vice versa between the alternating current bus and a direct current bus; at least one electrical power source arranged to provide power to the direct current bus; and wherein each of the at least two adjustable speed drive is connected, on a direct current side, to the direct current bus.
