Abstract
U ovom radu obrađena je tematika korištenja dvostruko napajanog asinkronog stroja kao jednog od koncepata upravljanja u vjetronaponskim sustavima. Teorijski su opisane sve komponente suvremenog vjetronaponskog sustava te je objašnjen način pretvorbe energije vjetra u električnu energiju uz dobivanje maksimalne izlazne snage. Navedene su sve prednosti korištenja ovog koncepta upravljanja te je isti uspoređen s ostalim konceptima upravljanja u smislu načina djelovanja, učinkovitosti i cijene. Dan je način djelovanja asinkronog stroja uz pripadajući matematički model u mirujućem i rotirajućem koordinatnom sustavu te je razrađeno načelo toka aktivne i reaktivne snage u slučaju sinkronog, nadsinkronog i podsinkronog načina rada. Kako bi se ispitale karakteristike mehaničkih i električnih veličina izveden je model upravljanja dvostruko napajanog asinkronog generatora u PLECS programskom paketu. Također su opisani svi elementi korištenog upravljačkog sustava kao i njihova hijerarhija djelovanja unutar strukture vektorskog upravljanja s orijentacijom statorskog toka i mrežnog napona. Simulacijom karakterističnih pojava tijekom ustaljenog stanja rada, prijelaznog stanja ubrzanja i usporavanja brzine vrtnje rotora te stanja kvara pada mrežnog napona, ispitana su međudjelovanja električnog i mehaničkog pogonskog sklopa. Analizom rezultata za različita pogonska stanja utvrđeno je kako predstavljeni sustav ima izrazito povoljne dinamičke karakteristike i potvrđena su sva teorijska razmatranja koja opisuju način djelovanja tog koncepta upravljanja.
Abstract (english)
This paper deals with double fed induction generator as one of the concepts of wind energy conversion systems. All components of the modern systems are presented and an explanation about wind power to electric power conversion with maximum power coefficient is given. All the advantages of using this control concept are listed and compared with other common control concepts in terms of performance, efficiency and cost. The principle of the induction machine's work with the corresponding mathematical model in the stationary and rotating coordinate system is described and the principle of active and reactive power flow in the case of synchronous, supersonic and sub-synchronous mode of operation is elaborated. In order to examine the characteristics of mechanical and electrical variables, model of double fed induction generator is created in the PLECS program package. All elements of the control systems used as well as their hierarchical actions within the structure of vector control with stator flux orientation and network voltage orientation are described too. By simulating the system during steady state of operation, transient acceleration state and rotor speed deceleration, as well as failure of network, electrical and mechanical drive circuit interactions were examined. Simulations for different operating conditions confirms that the presented system has well dynamic performances according to theoretical considerations of this control concept.
