ELECTRICAL POWER SYSTEM COMPRISING A PLURALITY OF GENERATORS DRIVEN BY ROTATION ON A COMMON SHAFT SUPPLYING ACTIVE RECTIFIERS, AND LOAD SHARING CONTROL

摘要

An electrical power system includes a DC bus (30) connected to a load (18), a plurality of generators (6) driven by rotation of a common shaft (8), and a plurality of power converters (10). Each power converter includes an active rectifier controller (24) that operates a respective active rectifier (22) to rectify AC from a respective one of the generators to DC on the DC bus. A load sharing controller (40) is operable to provide a respective adjustment signal to each respective power converter that is enabled, the respective adjustment signals based on a difference between an average output current across all of the active rectifiers that are enabled, and a particular output current of the respective power converter. Each active rectifier controller is operable to determine a quadrature current component value for its associated generator based on its adjustment signal.
