Abstract
U ovome diplomskome radu razvijena je kaskadna struktura upravljanja mrežnom stranom pretvarača vjetroagregata. Izvedeni su modeli LC filtra te istosmjernog međukruga koji se nalaze u Laboratoriju za sustave obnovljivih izvora energije Sveučilišta u Zagrebu Fakulteta elektrotehnike i računarstva. Unutarnji krug upravljanja strujom također je razdvojen u kaskadnu strukturu u kojoj se reguliraju mrežna struja i struja pretvarača. Za obje struje parametrirani su regulatori. Također je parametriran i regulator istosmjernog napona. Cijeli regulacijski krug je ispitan u Matlab-Simulink okruženju korištenjem PLECS-a. Nakon dobivanja zadovoljavajućih rezultata simulacijom krenulo se u implementaciju dobivenog rješenja na eksperimentalnom postavu. Provedene su simulacije sinkronizacije sustava na mrežu te su dodani elementi poput daljinski upravljanog sklopnika i pomoćnih otpornika u sustav. Također je izvršena korekcija parametara regulatora. Zatim je regulacijski krug testiran na promjene referentne veličine i na pojavu poremećaja. Ispitivana je regulacija na konstanti vjetar te na turbulentni vjetar. Regulacija se pokazala uspješnom u svim ispitivanim slučajevima. Na kraju su predložena neka poboljšanja.
Abstract (english)
As a part of this thesis, a multiloop control structure was developed for the control of a wind turbine grid side converter. First a model of the converter and the filter, that exist in the Laboratory for renewable energy systems University of Zagreb on the Faculty of Electrical Engineering and Computing, was made. The inner control loop was additionaly separated into another cascade structure within which regulation of grid current and converter current was enabled. For both currents, controller parameters were calculated. Also, for the DC link voltage control another controller was developed. The complete control loop was tested in the Matlab-Simulink environment with the help of PLECS. After obtainig of acceptable results via simulation the implementation on the experimental setup is performed. Another set of simulations was made for the grid synchronization of the system and additional element like remote controlled contactor and auxiliary resistances were added to the scheme. Some corrections of the controller parameters were made as well during the implementation on dSPACE. The control structure was lastly tested on the experimental setup for changes of the reference value and disturbances. Constant and turbulent wind changes were also tested. The controllers were successfull in every tested situation. In the end, some improvements were proposed.
