Beschreibung
In this work, a developed model of brushless synchronous generator of wound rotor type is designed, analyzed by FEM, practically applied and investigated. A comparison of results with conventional machines is also performed. The presented machine can be applied for multi-pole wind/ hydro generators or double-poles diesel-engine generators. It is self-excited by residual magnetism and a connected capacitor. It is also self-regulated by making use of fluctuations at load or limited speed changes. The generated voltage may last at extended speed range by arranging a generating system with variable capacitance. By eliminating the permanent magnets or advanced manufacturing technology of rotor poles; and without using extra rotating/ external DC exciters, an efficient excitation field and an output of flat self-compensated compound characteristic are obtained. More, the feature of damper windings is determined.
Concerning the fact of environmental diminishing of elements in materials of permanent magnets and D.C. Battery, the presented novel machine is hence a good alternative and more economic from generators, exist in the market. Beside, it is safer and highly recommended for power stability when connected to the grid.
