Research Of The Controller For 60kva Vscf Aircraft Electric Power Supply System

The Generator/Converter Control Unit (abbr. GCU) is an important constituent of the VSCF electric power system. It can not only coordinates the operation between generator and converter in order to meet output request of VSCF power system, as well as controls, protects the whole system, but also can achieve BIT, communication, fault isolating and displaying functions.The thesis presents a detailed illumination of Generator/Converter Control Unit of 6OkVA VSCF electric power system. It describes the construction and work principle of GCU, especially for technology of large-power converter controller with dynamic waveform correction, design of Automatic Voltage Regulator with Negative Field Forcing and excite current soft feedback, and fault analysis as well as diagnosis and isolation technology of VSCF power system.The outcome of these critical technology researching has applied to the GCU example design of 6OkVA VSCF power system that has been researched in advance. It proved that these critical technologies used by this GCU example was feasible, and all kinds technical performance of GCU achieved the request of research in advance.
