Dzhura O. Single-phase stand-alone induction generator with valve-capacity excitation

The object of research: electromechanical energy conversion in stand-alone single phase electrogenerating aggregates. The purpose of research: increase of reliability, improvement of electric energy quality and increase in functional possibilities of autonomous single-phase electrogenerating aggregates. Methods of research: Laplace conversion, equivalent source, imposition, equivalent circuits, symmetric components, nodal admittance, switching functions, mathematical and physical simulation. Theoretical and practical results and innovations: mathematical models of stand-alone single-phase induction generators (SPIG) with valve-capacity excitation (VCE) are developed; local optimization of parameters of capacity systems of excitation is conducted; the conditions of sircle-type magnetic field in SPIG with three phase stator winding are defined; the methods of control of SPIG with VCE are developed; the comparative analysis of SPIG is conducted. A subject and degree of the application: the results areimplemented in NTUU “KPI” and DRI WIT “Neftegazstroyizoliatsia”. Effectiveness of implantation: reliability rise and electric energy quality improvement of autonomous electroaggregates. The sphere of application: autonomous energetics.
