Novi regulator struje za dvostrano napajani asinkroni generator

Abstract

This paper presents a novel current control methodology for grid connected doubly-fed induction generator (DFIG) based wind energy conversion systems. Controller is based on a proportional controller with additional first order low pass filter disturbance observer which estimates the parameter dependent nonlinear feed-forward terms. The results in simulations and experimental test bed obviously demonstrate that decoupled control of active and reactive power is achieved without the necessity of additional machine parameter.U ovom radu prikazana je nova metoda upravljanja strujom za vjetroagregat s dvostrano napajanim asinkronim generatorom spojen na mrežu. Regulator se temelji na proporcionalnom regulatoru uz dodatak niskopropusnog fitra prvog reda za estimaciju poremećaja koji estimira parametarski ovisne nelinearne predupravljačke članove. Simulacijski i eksperimentalni rezultati pokazuju da je postignuto raspregnuto upravljanje radnom i jalovom snagom bez potrebe za dodatnim parametrima generatora.
