摘要： It is presented an apparatus for reducing reactive power consumption of auxiliaries in an electrical power generation plant. The apparatus comprises: at least one adjustable speed drive with an associated motor; at least one reactive power consuming auxiliary device; at least one sensor for measuring a reactive power; and a controller. The controller is connected to the at least one sensor and the at least one adjustable speed drive, for controlling the at least one adjustable speed drive such that a reactive power of the at least one adjustable speed drive at least partly compensates a reactive power consumed by the at least one reactive power consuming auxiliary device. A corresponding method and computer program product are also presented.

摘要： A multi-stage centrifugal compressor multi-stage centrifugal compressor with an integral high-speed motor for compressing air has a variable speed permanent magnet motor having electronically commutated stator coils surrounding a rotor carrying permanent magnets, wherein there is a gap between the coils and the rotor. The rotor has a magnetic steel rotor shaft rotatably supported at each end by pressurized oil lubricated hydrodynamic bearings. The stator coils have a plurality of stator wires extending longitudinally along the stator and continuing around the ends of the stator to define end turns. The compressor also has a plurality of compressor impellers mounted to turn with the rotor shaft and cooler for cooling the bearings, rotor and stator coils comprising a pump for introducing cooled oil into the bearings, said bearing configured so that oil exiting from the bearings splashes over the supported ends of the shaft and splashes over the end turns of the stator coils. There is a passageway through the stator for introducing pressurized air within a gap between the stator and the rotor during start up to maintain a positive pressure within the gap thereby displacing oil from the gap.

摘要： A multi-stage centrifugal compressor with an integral high-speed motor compressing a stator (52), a rotor (28) carrying permanent magnets (72a-72d), wherein there is a gap (50) between the stator (52) and the rotor (28). The rotor (28) has a magnetic steel rotor shaft (75) rotatably supported at each end by pressurized oil lubricated hydrodynamic bearings (53,54). The compressor also has a plurality of compressor impellers (26,27) mounted to turn with the rotor shaft (75) and a pump (29) for delivering cooling oil to the bearings (53, 54). Also, there is a passageway (66) through the stator (52) for introducing pressurized air within a gap (50) during start up to maintain a positive pressure within the gap thereby displacing oil from the gap (50).
